14 Best ADA Compliant Toilets That Combine Accessibility and Style

ADA-compliant toilets are designed around accessible seat-height requirements, but the right choice also depends on bowl shape, bathroom layout, flush system, and installation type. My best overall pick is the DeerValley ADA Two-Piece Elongated Toilet, which pairs an ADA-focused design with a power flush and soft-close seat. The TOTO Drake stands out for its established flush and bowl-coating features, while the HOROW 17-Inch Comfort-Height Toilet is a practical alternative for shoppers who want dual flush. The main tradeoffs are between a standard-height accessible seat and taller models, one-piece convenience and two-piece serviceability, and residential toilets versus flushometer bowls made for compatible commercial plumbing. Read on for the full comparison and guidance on choosing a model that fits both the user and the bathroom.

Key Takeaways

• The DeerValley ADA Two-Piece is the clearest all-around fit in this lineup: it combines an ADA-focused design, elongated bowl, 1.28 GPF power flush, 12-inch rough-in, and soft-close seat.
• Seat height varies more than the product names suggest. The lineup ranges from 17-inch comfort-height models to a 21-inch-high option, so check the actual seat height and user needs rather than relying on “ADA” or “comfort height” wording alone.
• One-piece construction favors easier exterior cleaning, with several Casta Diva, HOROW, and DeerValley options; two-piece designs may be a more familiar service choice and include the standout power-flush pick.
• Round bowls and commercial flushometer bowls serve narrower needs. BAYROLL’s round bowl may help with a tight footprint, while the Kohler Highcliff is a commercial-style bowl that requires compatible flushometer hardware rather than a typical residential tank.
• Not every tall toilet is automatically the right accessible toilet. The SUPERFLO’s 21-inch height may suit some users, but that measurement calls for extra care around transfer comfort, user fit, and the distinction between seat height and bowl height.

More Details on Our Top Picks

1. DeerValley ADA Two-Piece Elongated Toilet with Power Flush, 1.28 GPF, 12-Inch Rough-In, and Soft-Close Seat

   

   Best for a Stronger-Action Flush

   View on Amazon

   The DeerValley pairs a 17 13/16-inch seat with an elongated bowl, giving it one of the taller seating positions in this group. Its 360-degree power-flush jets are the main distinction: buyers who prioritize forceful bowl rinsing may prefer this setup to the standard 1.28 GPF single flush on the HOROW HR-E17S. Both are two-piece toilets built for a 12-inch rough-in, but the DeerValley includes a soft-close seat and uses 1.28 gallons per flush. The tradeoff is practical rather than complicated: at 90 pounds, it still takes care to handle, and its warranty is limited to one year. Choose it for the flush design and tall seat, not for extended warranty coverage.

   Pros:

   • 17 13/16-inch seat height supports a higher sitting position.
   • 360-degree power-flush jets are designed to rinse around the bowl.
   • Elongated bowl and soft-close seat are included.
   • Uses 1.28 GPF and fits a standard 12-inch rough-in.

   Cons:

   • One-year limited warranty is shorter than buyers seeking long-term coverage may want.
   • At 90 pounds, handling during installation may be difficult without help.

   Best for: Buyers seeking an elongated, taller-seat toilet with a forceful 360-degree flush and a standard 12-inch rough-in.

   Not ideal for: Shoppers who want dual-flush water settings or longer stated warranty coverage; this model offers one flush rate and a one-year limited warranty.

   • Type:Two-piece, floor-mounted toilet
   • Seat height:17 13/16 inches
   • Bowl shape:Elongated
   • Flush rate:1.28 GPF
   • Rough-in:12 inches
   • Dimensions:27.56 × 16.14 × 30.91 inches (D × W × H)
   • Material:Ceramic
   • Warranty:One-year limited warranty
   Our verdict

   “Choose the DeerValley if you want a taller elongated toilet with a jet-assisted 1.28 GPF flush and do not need dual-flush controls.”

   → See it on Amazon →

2. HOROW 17-Inch Comfort-Height Elongated Two-Piece Toilet with Dual Flush

   

   Best for Dual-Flush Flexibility

   View on Amazon

   The HOROW HR-E17D is the pick here for buyers who want to choose between 1.1 and 1.6 GPF rather than use a single flush rate. Its 17-inch seat and elongated bowl make it a comfort-height option, while the included installation components reduce the need to source basic fitting parts separately. The DeerValley offers a slightly taller seat and a 360-degree jet flush, but it does not provide the HOROW’s two flush-volume choices. The Casta Diva CD-T006 uses even less water for its liquid flush and has a skirted one-piece body, making it a different fit for buyers focused on water use or easier exterior cleaning. At 95 pounds, this HOROW is the heaviest option in this five-product set, and its 12-inch rough-in requirement narrows fit.

   Pros:

   • Dual-flush controls offer 1.1 and 1.6 GPF options.
   • 17-inch seat and elongated bowl provide a higher, roomier seating profile.
   • Installation components, including a wax ring and T-bolts, are included.
   • Manufacturer reports MAP 1000g flushing performance.

   Cons:

   • At 95 pounds, it is the heaviest of the five toilets reviewed here.
   • Requires a standard 12-inch rough-in.
   • One-year limited warranty is stated, with lifetime after-sales service rather than a longer stated product warranty.

   Best for: Households that want an elongated chair-height toilet with separate lower-volume and full flush choices, plus included installation parts.

   Not ideal for: Buyers who need a lighter toilet to handle during installation or whose bathroom has a rough-in other than 12 inches.

   • Type:Two-piece elongated toilet
   • Seat height:17 inches
   • Flush system:Dual flush, 1.1/1.6 GPF
   • Reported flushing performance:MAP 1000g
   • Rough-in:12 inches
   • Dimensions:28.8 × 14.2 × 33 inches (D × W × H)
   • Weight:95 pounds
   • Material:Glazed ceramic
   • Included components:Bowl, tank, seat, caps, T-bolts, and wax ring
   Our verdict

   “Pick the HOROW HR-E17D if variable flush volumes matter more to you than minimizing installation weight.”

3. Casta Diva Elongated One-Piece Toilet with 17.5-Inch Comfort-Height Seat

   

   Best for Easy Exterior Cleaning

   View on Amazon

   For buyers who want an accessible-height toilet with fewer exposed exterior joints, the Casta Diva CD-T006 stands apart with its fully skirted one-piece design. Its 17.5-inch seat is taller than the 17-inch HOROW HR-E17D, while the dual-flush system uses 1.0 GPF for liquids and 1.28 GPF for solids. That can suit households looking to limit water use on lighter flushes; the DeerValley instead emphasizes its 360-degree power-flush jets and a slightly different two-piece layout. The quick-release, soft-close seat supports seat removal for cleaning, and installation hardware is included. The tradeoffs are its fixed 12-inch rough-in and a one-year customer-service warranty. Its one-piece form may also make handling less convenient than a two-piece toilet during installation.

   Pros:

   • 17.5-inch seat provides a higher seating position than the 17-inch HOROW models.
   • Dual flush uses 1.0 GPF for liquids and 1.28 GPF for solids.
   • Skirted one-piece exterior has fewer exposed contours to clean.
   • Quick-release soft-close seat and installation hardware are included.

   Cons:

   • Requires a standard 12-inch rough-in.
   • One-year customer-service warranty is limited.
   • One-piece construction can be more cumbersome to handle than a two-piece toilet.

   Best for: Buyers who want a taller-seat, dual-flush toilet with a skirted exterior and a removable seat for cleaning access.

   Not ideal for: Those whose plumbing does not use a 12-inch rough-in or buyers who prefer separate bowl and tank pieces for easier handling.

   • Type:One-piece, elongated toilet
   • Seat height:17.5 inches
   • Flush system:Dual flush
   • Flush rates:1.0 GPF for liquids; 1.28 GPF for solids
   • Rough-in:12 inches
   • Dimensions:25.39 × 14.56 × 26.57 inches
   • Seat:Soft-close, quick-release polypropylene
   • Certification:cUPC; ADA-compliant
   • Warranty:One-year limited customer service; lifetime technical consulting
   Our verdict

   “Choose the Casta Diva if a skirted one-piece body and low-volume liquid flush matter more than two-piece handling or longer stated warranty coverage.”

   → See it on Amazon →

4. HOROW 17-Inch High Elongated Two-Piece Toilet, ADA Comfort Height, 1.28 GPF

   

   Best Straightforward Single-Flush Pick

   View on Amazon

   The HOROW HR-E17S is the uncomplicated choice for shoppers who want a 17-inch seat and one consistent 1.28 GPF flush rather than dual-flush controls. Its 360-degree siphon flush and reported MAP 1000g rating make it a stronger fit for buyers focused on flushing performance than on selecting different water volumes. Compared with the HOROW HR-E17D, it gives up the 1.1/1.6 GPF options but keeps operation simple; compared with the DeerValley, it uses a siphon-flush description rather than 360-degree power jets. The two-piece build, soft-close seat, and included installation accessories cover the basics, though assembly is required. The specified 12-inch rough-in also limits where it can fit, so measure before choosing it.

   Pros:

   • 17-inch height and elongated bowl suit buyers seeking a higher seating position.
   • Single 1.28 GPF flush keeps operation straightforward.
   • 360-degree siphon flush has a reported MAP 1000g rating.
   • Soft-close seat and installation accessories are included.

   Cons:

   • Two-piece bowl and tank require assembly.
   • Only a 12-inch rough-in is specified.
   • One-year limited warranty is stated, despite lifetime after-sales service.

   Best for: Buyers who want a 17-inch comfort-height elongated toilet with a single 1.28 GPF flush and included installation accessories.

   Not ideal for: Households seeking dual-flush water choices, a one-piece skirted design, or a toilet for a non-12-inch rough-in.

   • Type:Two-piece elongated toilet
   • Height:17 inches
   • Flush:Single flush, 1.28 GPF
   • Reported flushing performance:MAP 1000g
   • Rough-in:12 inches
   • Dimensions:29.5 × 14.2 × 32.3 inches (D × W × H)
   • Material:Ceramic
   • Included components:Bowl, tank, seat, caps, T-bolts, and wax ring
   • Warranty:One-year limited warranty; lifetime after-sales service
   Our verdict

   “Choose the HOROW HR-E17S if you prefer a simple single-flush, comfort-height toilet over the dual-flush flexibility of the HR-E17D.”

   → See it on Amazon →

5. Garvee ADA-Compliant Elongated Two-Piece Toilet with Soft-Close Seat

   

   Best for a Lower Seat Height

   View on Amazon

   The Garvee takes a different approach to accessible seating: its listed 16-inch seat height is lower than the 17- to 17 13/16-inch seats on the HOROW and DeerValley options. That makes it worth comparing for buyers who find taller comfort-height toilets too high, though the product description calls it ADA-compliant and shoppers should confirm that its measured seat height suits their needs and applicable requirements. Its 1.28 GPF side-push flush matches the single-flush rate of the HOROW HR-E17S, while the locking soft-close seat adds a secure-fit detail not specified for that model. The Garvee is wide at 18.9 inches and weighs 93.4 pounds, so it may be a poor fit for tighter spaces or solo installation. cUPC certification and a 12-inch rough-in are listed.

   Pros:

   • 16-inch seat offers a lower alternative to the 17-inch-plus seats on several picks here.
   • 1.28 GPF side-push flush is designed for water efficiency.
   • Locking polypropylene seat has a soft-close lid.
   • cUPC certification and a standard 12-inch rough-in are specified.

   Cons:

   • Listed seat height is lower than the other toilets in this group, so check fit against individual accessibility needs.
   • At 18.9 inches wide, it may be difficult to fit in a constrained bathroom.
   • At 93.4 pounds, installation handling may require assistance; no flush-performance rating is provided.

   Best for: Buyers who prefer a lower 16-inch seat than the taller HOROW or DeerValley options and need a standard 12-inch rough-in.

   Not ideal for: Shoppers who specifically need a 17-inch-or-higher seat, have limited width, or want documented flushing-performance details.

   • Type:Two-piece, floor-mounted toilet
   • Seat height:16 inches
   • Bowl shape:Elongated
   • Flush rate:1.28 GPF
   • Flush control:Side push
   • Rough-in:12 inches
   • Dimensions:27.76 × 18.9 × 30.12 inches
   • Weight:93.4 pounds
   • Certification:cUPC
   Our verdict

   “Consider the Garvee if you want a lower seat and locking soft-close lid, but verify the seat height and width against your bathroom and accessibility needs.”

   → See it on Amazon →

6. Casta Diva Elongated One-Piece Toilet with 17.2-Inch ADA Comfort Height

   

   Best for Low-Water Flush Controls

   View on Amazon

   This Casta Diva stands apart for buyers who want an elongated, 17.2-inch seat paired with a very low 1.0 GPF flush. Its air-pressure-assisted siphon system offers both a side button and a foot-kick control, giving users a choice of operation; the product details do not explain whether a backup flush is available if the assisted mechanism is unavailable. Compared with the dual-flush Casta Diva CD-T005, this model uses less water per flush but does not offer a separate liquids setting. The one-piece skirted base also presents fewer exposed contours to clean than a conventional two-piece design. A 12-inch rough-in is required, and its listed height is a seat measurement, so I would verify the complete installed dimensions and accessibility needs before buying.

   Pros:

   • 17.2-inch seat height and elongated bowl
   • 1.0 GPF air-pressure-assisted siphon flush
   • Foot-kick and side-button flush controls
   • Soft-close seat and wax ring and mounting hardware included

   Cons:

   • Requires a 12-inch rough-in
   • No electricity-free or other backup-flush details are provided

   Best for: Households seeking an elongated comfort-height toilet with a 1.0 GPF flush and alternative foot-kick or button operation.

   Not ideal for: Buyers with a nonstandard rough-in or anyone who needs documented details about manual backup operation.

   • Seat height:17.2 inches
   • Flush rate:1.0 GPF
   • Flush system:Air-pressure-assisted siphon jet
   • Flush controls:Foot-kick or side button
   • Rough-in:12 inches
   • Dimensions:26.9 x 15 x 19.3 inches (D x W x H)
   • Material:Vitreous china
   • Installation:Floor mounted
   Our verdict

   “Choose this Casta Diva for its low-volume flush and flexible controls, provided your bathroom has a 12-inch rough-in and the flush system suits your needs.”

   → See it on Amazon →

7. Casta Diva Elongated One-Piece Toilet with 17-Inch Comfort Height Seat

   

   Best for Dual-Flush Water Control

   View on Amazon

   The CD-T005 is the straightforward choice here for buyers who want to select flush volume: its dual-flush controls use 1.1 GPF for liquids and 1.6 GPF for solids. That makes it distinct from the 1.0 GPF Casta Diva CD-W001, which uses less water per flush but provides no separate liquid setting. The CD-T005 pairs its flush with a 17-inch seat, compact elongated bowl, and quick-release soft-close seat; the release feature can make routine cleaning easier. Its fully glazed trapway is designed to support a quiet, effective flush, though the supplied details do not give a MaP score for comparison with the BAYROLL SH-S001. This remains a floor-mounted toilet with a 12-inch rough-in, and its stated customer-service coverage is limited to one year, so check fit and support expectations before choosing it.

   Pros:

   • Dual flush uses 1.1 GPF for liquids and 1.6 GPF for solids
   • 17-inch seat and compact elongated bowl
   • Fully glazed trapway
   • Quick-release, soft-close seat; wax seal and installation hardware included

   Cons:

   • Requires a 12-inch rough-in
   • Listed customer-service coverage is one year

   Best for: Homeowners with a standard 12-inch rough-in who want an elongated comfort-height toilet and separate liquid and solid flush settings.

   Not ideal for: Buyers who prioritize the lowest stated per-flush volume or need longer customer-service coverage.

   • Model:CD-T005
   • Type:One-piece elongated toilet
   • Seat height:17 inches
   • Flush type:Dual flush
   • Flush rates:1.1 GPF (liquids), 1.6 GPF (solids)
   • Rough-in:12 inches
   • Dimensions:27.17 D x 14.37 W x 25.39 H inches
   • Warranty and support:1-year limited customer service; lifetime technical consulting
   Our verdict

   “Pick the CD-T005 if adjustable flush volume and an easy-release seat matter more to you than the CD-W001’s lower single-flush rate.”

   → See it on Amazon →

8. BAYROLL One-Piece Round Toilet, 17-Inch ADA Chair Height, Dual Flush

   

   Best Compact Choice

   View on Amazon

   For a bathroom where front-to-back clearance matters, the BAYROLL’s 25.5-inch depth and round bowl make it a more compact option than the elongated Casta Diva CD-T005. It still offers a 17-inch seat and dual flush, with 0.9 GPF for liquids and 1.28 GPF for solids. The listed MaP score is 1000 g, providing a performance detail absent from the CD-T005 specifications. Its fully skirted, one-piece construction and quick-release seat can simplify surface cleaning, but compactness comes with a shorter round bowl rather than the elongated seating area of the TOTO Drake. The package includes several installation accessories, yet the water supply pipe and floor flange are not included. I would also confirm valve placement and clearances before ordering; the one-year guarantee is relatively limited.

   Pros:

   • Compact 25.5-inch depth and 14.7-inch width
   • Dual flush uses 0.9 GPF for liquids and 1.28 GPF for solids
   • 17-inch seat and listed 1000 g MaP score
   • Fully skirted body and soft-close, quick-release seat

   Cons:

   • Round bowl provides less seating length than the elongated Casta Diva CD-T005 or TOTO Drake
   • Water supply pipe and floor flange are not included
   • Valve placement and clearances need checking; guarantee is one year

   Best for: Owners of smaller bathrooms who need a round-bowl, 17-inch-seat toilet with dual-flush options.

   Not ideal for: Buyers who prefer an elongated bowl, need all plumbing parts supplied, or cannot verify the listed valve clearances.

   • Type:One-piece, round, fully skirted
   • Seat height:17 inches
   • Dimensions:25.5 x 14.7 x 27 inches
   • Rough-in:12 inches
   • Flush type:Dual-flush siphon
   • Flush volume:0.9 GPF / 1.28 GPF
   • MaP score:1000 g
   • Warranty:1 year
   Our verdict

   “Choose the BAYROLL when bathroom footprint is the priority and a round bowl is acceptable, after confirming installation clearances and sourcing the missing plumbing parts.”

9. TOTO Drake Two-Piece Elongated Toilet, 1.6 GPF, Universal Height, Tornado Flush, CEFIONTECT, Cotton White

   

   Best for Bowl-Cleaning Features

   View on Amazon

   The TOTO Drake suits buyers who value bowl-rinsing features and an established two-piece format alongside an ADA-compliant Universal Height. Its Tornado Flush system and CEFIONTECT glaze are designed to rinse the bowl and reduce waste buildup, while the 1.6 GPF flush is higher than the 1.0 GPF Casta Diva CD-W001 and the BAYROLL’s 1.28 GPF solid setting. That higher volume is a tradeoff for shoppers focused on water use. The elongated bowl offers more seating length than the round BAYROLL, but this package is less complete: a seat, wax ring, mounting bolts, and supply lines are sold separately. Compared with the one-piece Casta Diva models, the Drake’s tank-and-bowl construction has a visible joint, so it is a better fit for buyers prioritizing its flushing and glaze features over a seamless exterior.

   Pros:

   • Universal Height design identified as ADA compliant
   • Tornado Flush and CEFIONTECT glaze are designed to help keep the bowl clean
   • Elongated bowl
   • 3-inch flush valve and siphon jet bowl

   Cons:

   • Uses 1.6 GPF, more than the Casta Diva CD-W001 and BAYROLL solid flush
   • Seat, wax ring, mounting bolts, and water supply lines are sold separately
   • Two-piece construction has a tank-to-bowl joint to clean

   Best for: Buyers seeking an ADA-compliant elongated toilet with bowl-rinsing technology who are comfortable sourcing a seat and installation supplies separately.

   Not ideal for: Water-conscious households focused on lower flush volumes, or buyers who need a more complete installation package.

   • Type:Two-piece elongated toilet
   • Height:Universal Height; ADA compliant
   • Flush rate:1.6 GPF
   • Flush system:Tornado Flush
   • Glaze:CEFIONTECT
   • Rough-in:12 inches
   • Trap seal:2-1/8 inches
   • Minimum flowing water pressure:8 psi
   Our verdict

   “Choose the TOTO Drake if its Universal Height and bowl-cleaning features outweigh the higher flush volume and separately purchased installation items.”

10. Kohler Highcliff Ultra ADA-Height Flushometer Bowl with Top Spud

    

    Best for Commercial Flushometer Setups

    View on Amazon

    Unlike the residential tank toilets in this group, the Kohler Highcliff Ultra is a bowl designed for a flushometer valve, making it the specialized choice for commercial-style installations. Its 16-7/8-inch rim height is listed as meeting ADA and CSA height requirements, and the bowl can operate across 1.1–1.6 GPF, with the supplied data also noting operation at 1.0 GPF. It accepts several valve types, which gives installers more setup options than the tank-based TOTO Drake, but the flushometer valve itself is not included. A seat and typical tank-to-bowl components are also not part of this bowl-only package. The 28.25-inch listed depth and 52-pound weight call for careful fit and handling checks. I would choose it for a compatible flushometer system, not as a direct replacement for a complete residential toilet.

    Pros:

    • Rim height meets listed ADA and CSA height requirements
    • Compatible with diaphragm, piston, manual, and electronic flush valves
    • Flush engine range includes 1.1–1.6 GPF and can operate at 1.0 GPF
    • Elongated vitreous china bowl with 2-1/8-inch trap passageway

    Cons:

    • Flushometer valve is not included
    • Bowl-only package does not provide a complete residential toilet setup
    • 52-pound weight and 28.25-inch depth require handling and fit planning

    Best for: Facility managers or renovators replacing a floor-mounted flushometer bowl in a compatible commercial restroom.

    Not ideal for: Residential buyers seeking a complete tank-and-bowl toilet or anyone without a compatible flushometer valve and installation plan.

    • Type:Floor-mounted elongated toilet bowl
    • Height to rim:16-7/8 inches
    • Flush volume:1.1–1.6 GPF; can operate at 1.0 GPF
    • Spud:1-1/2-inch top spud
    • Trap passageway:2-1/8 inches
    • Dimensions:28.25 x 20.5 x 30 inches
    • Weight:52 pounds
    • Warranty:One-year limited
    Our verdict

    “Select the Highcliff Ultra for a compatible commercial flushometer installation; choose the TOTO Drake instead if you need a complete tank-and-bowl toilet.”

11. SUPERFLO 21-Inch High Elongated Toilet

    

    Best for Extra-High Seating

    The SUPERFLO’s standout is its 21-inch height, which sits higher than the 17.9-inch Los Flexi and the 17.5-inch DeerValley. That added height may make sitting down and standing up easier for some taller users or people with limited mobility, but it is not the usual ADA-height target, so I’d check the seat-height requirement for the intended user rather than assume it suits everyone. Its elongated bowl, soft-close removable seat, and 1.28 GPF flush cover practical everyday needs. Compared with the Los Flexi, it offers a taller seat and a stated 1,000-gram MAP performance figure, while the Los Flexi provides a more conventional height and a two-piece format. The SUPERFLO also has a 12-inch rough-in requirement, and its listed weight of 100 g appears incomplete or inaccurate, leaving a question for installation planning.

    Pros:

    • 21-inch height may reduce the effort of sitting and standing for some users
    • Elongated ceramic bowl with a soft-close, removable seat
    • 1.28 GPF single flush and stated 1,000-gram MAP performance
    • Installation accessories and a two-year warranty are included

    Cons:

    • At 21 inches, the seat is higher than the 17.9-inch Los Flexi and may not suit every user or accessibility plan
    • Requires a 12-inch rough-in
    • Listed weight of 100 g appears incomplete or inaccurate

    Best for: Taller adults and users who specifically need a seat higher than standard ADA-height models and have a verified 12-inch rough-in.

    Not ideal for: Buyers seeking a conventional ADA-height seat or those who need reliable, confirmed product weight before arranging delivery and installation.

    • Model:HT-140
    • Toilet height:21 inches
    • Bowl shape:Elongated
    • Rough-in:12 inches
    • Flush:Single flush, 1.28 GPF
    • Waste removal performance:1,000 grams MAP
    • Dimensions:29.3 x 14.7 x 35.2 inches
    • Warranty:Two years
    Our verdict

    “Choose the SUPERFLO if a specifically extra-high 21-inch seat is the priority and its rough-in and height suit the user.”

12. Los Flexi ADA Two-Piece Elongated Toilet, 17.9-Inch Comfort Height, 1.28 GPF

    

    Best for Conventional ADA-Height Seating

    View on Amazon

    The Los Flexi pairs a 17.9-inch height with an elongated bowl, making it the most straightforward fit here for shoppers prioritizing a conventional ADA-height configuration. Its two-piece construction separates tank and bowl for handling, though the listed 81.5-pound weight still means installation may take help. A 360-degree siphon flush is designed to distribute water around the bowl, while the 1.28 GPF rate keeps flush volume clear and consistent. Compared with the 21-inch SUPERFLO, the Los Flexi is less unusually tall; compared with the HOROW T0338W, it has a higher listed seat height and a two-year rather than one-year warranty. The tradeoff is that it lacks dual-flush options, and its weight can complicate a do-it-yourself install. The supplied kit helps, but buyers should confirm the rough-in and installation needs before ordering.

    Pros:

    • 17.9-inch height and elongated bowl suit buyers seeking a conventional ADA-height setup
    • 360-degree siphon flush is designed for thorough bowl coverage
    • Soft-close polypropylene seat
    • Includes a 12-inch rough-in installation kit and two-year warranty

    Cons:

    • Listed weight of 81.5 pounds can make installation harder for one person
    • Single 1.28 GPF flush offers no lower-volume dual-flush choice

    Best for: Households seeking an elongated toilet with a clearly specified 17.9-inch ADA-height configuration, standard 12-inch rough-in, and included installation kit.

    Not ideal for: Solo DIY installers who cannot comfortably handle an 81.5-pound fixture, or buyers who want dual-flush water-use options.

    • Model:KBT17
    • Toilet type:Two-piece
    • Height:17.9 inches
    • Bowl shape:Elongated
    • Flush rate:1.28 GPF
    • Rough-in:12 inches
    • Dimensions:27.56 x 17.13 x 32.09 inches (D x W x H)
    • Weight:81.5 pounds
    • Warranty:Two years
    Our verdict

    “Pick the Los Flexi for a conventional ADA-height elongated toilet with a defined installation kit and warranty, provided you can manage its weight.”

13. HOROW T0338W One-Piece Elongated Toilet, ADA Chair Height, Dual Flush

    

    Best Compact One-Piece Pick

    View on Amazon

    The HOROW T0338W is the compact-format choice in this group: its listed depth is 26.6 inches, and its one-piece ceramic body avoids the tank-to-bowl seam found on the two-piece Los Flexi. That can simplify routine exterior cleaning, though its 17.3-inch seat height is lower than the Los Flexi’s 17.9 inches and DeerValley’s 17.5 inches. Its dual flush, 1.1 or 1.6 GPF, lets users choose between lower and higher flush volumes, unlike the Los Flexi’s single 1.28 GPF flush. The siphon flush and fully glazed 2-inch trapway support waste passage, while included floor bolts and a wax ring help with setup. The compromises are a 99.2-pound listed weight and a one-year limited warranty, shorter than Los Flexi’s two years. Check the 12-inch rough-in against the bathroom before choosing it for a tight layout.

    Pros:

    • Compact 26.6-inch listed depth and one-piece body
    • Dual-flush choices of 1.1 and 1.6 GPF
    • Fully glazed 2-inch trapway with siphon flush
    • Includes floor bolts, wax ring, and soft-close seat

    Cons:

    • 17.3-inch seat height is lower than the Los Flexi and DeerValley models in this batch
    • Listed 99.2-pound weight may make installation difficult
    • One-year limited warranty is shorter than the Los Flexi’s two-year coverage

    Best for: Buyers with limited front-to-back space who want a one-piece elongated toilet, dual-flush options, and included basic installation hardware.

    Not ideal for: Users who need a higher seat than 17.3 inches, or installers who need a lighter fixture and longer warranty coverage.

    • Model:T0338W
    • Configuration:One-piece, floor-mounted
    • Seat height:17.3 inches
    • Dimensions:26.6 x 15 x 26 inches (D x W x H)
    • Flush:Dual flush, 1.1/1.6 GPF
    • Trapway:Fully glazed, 2 inches
    • Rough-in:12 inches listed
    • Weight:99.2 pounds
    • Warranty:One-year limited
    Our verdict

    “Choose the HOROW T0338W when compact depth and dual-flush flexibility matter more than a higher seat or longer warranty.”

14. DeerValley Elongated One-Piece Toilet with ADA-Height Seat, DV-1F0437

    

    Best for Easy-Clean Features

    View on Amazon

    The DeerValley earns its place through a practical mix of 17.5-inch seat height and cleaning-friendly details. Its rimless bowl and quick-release, soft-close seat make it easier to reach around the bowl and remove the seat for more thorough cleaning. Against the HOROW T0338W, DeerValley offers a slightly higher listed seat and a quick-release seat, while the HOROW provides a longer warranty and includes installation hardware. DeerValley’s dual flush at 1.1 or 1.28 GPF gives a lower-volume option than the Los Flexi’s single 1.28 GPF flush, and its stated 1,000g MaP score provides a waste-removal performance reference. The limitations are a one-year warranty and sparse installation details: the listed 12-inch rough-in is useful, but included components are not specified. I’d confirm what arrives in the box before scheduling installation.

    Pros:

    • 17.5-inch seat height in an elongated one-piece design
    • Rimless bowl and quick-release seat simplify cleaning access
    • Dual flush uses 1.1 or 1.28 GPF
    • Stated 1,000g MaP score

    Cons:

    • One-year warranty is shorter than the Los Flexi’s two-year coverage
    • Installation details and included components are not fully specified
    • Requires a 12-inch rough-in

    Best for: Buyers who prioritize easier bowl and seat cleaning, want a 17.5-inch seat, and prefer a dual-flush one-piece design.

    Not ideal for: Shoppers who need a longer warranty or want clearly listed installation hardware and included components before purchase.

    • Model:DV-1F0437
    • Configuration:One-piece
    • Seat height:17.5 inches
    • Bowl:Elongated, rimless
    • Flush:Dual flush, 1.1 or 1.28 GPF
    • MaP score:1,000g
    • Dimensions:26.77 x 14.5 x 26.6 inches (D x W x H)
    • Rough-in:12 inches
    • Warranty:One year
    Our verdict

    “Choose the DeerValley if easy-clean features and a 17.5-inch seat outweigh the shorter warranty and less-defined installation package.”

How We Picked

I ranked these toilets by how clearly their stated features support an accessible bathroom, then weighed everyday fit and ownership needs. The main criteria were seat-height information, elongated or round bowl shape, flush type and stated water use, construction style, installation details such as rough-in, and features that affect cleaning or routine use. I gave more weight to products with concrete specifications and a clear residential use case than to models whose naming leaves key fit details uncertain.

The order reflects role and usability, not a claim that one height suits every user. The DeerValley ADA Two-Piece leads for its combination of accessibility-focused design, flush performance, and stated 12-inch rough-in; the TOTO Drake earns a distinct place for its flush and bowl-coating features, though its listed universal height should be checked against the buyer’s needs. One-piece models rank well for simple exterior cleaning, while the commercial Kohler bowl and extra-tall SUPERFLO are more specialized. I would verify local accessibility requirements, seat-height measurements, rough-in, clearance, and plumbing compatibility before purchase; product labeling alone does not confirm that a complete installation meets code.

Factors to Consider When Choosing Ada Compliant Toilets

Choosing among accessible-height toilets takes more than matching a label. I would begin with the user’s transfer needs and the room’s existing plumbing, then compare bowl shape, seat height, flushing setup, and service requirements. These checks can prevent a toilet that sounds right on paper from being uncomfortable or difficult to install.

Check the actual seat height, not just the label

Terms such as ADA height, comfort height, and chair height are not a substitute for the exact installed seat height. Product specifications may give bowl height without the seat, so confirm which measurement is being quoted and whether a seat is included. A taller seat can make sitting and standing easier for some adults, but it may leave a shorter user’s feet unsupported or make transfers harder. If more than one person will use the bathroom, match the height to the primary user while accounting for everyone’s balance and mobility. For a project subject to accessibility rules, have the finished installation checked against the applicable requirements rather than treating a product description as certification.

Match bowl shape and clearances to the room

An elongated bowl generally gives more front-to-back seating space, but it also takes up more room than a round bowl. That difference can affect door swing, approach space, and a wheelchair user’s ability to position beside the toilet. A round model such as the BAYROLL may fit a compact bathroom, yet its smaller footprint does not by itself make the room accessible. Measure from the finished wall, check the toilet’s projection, and map required side and front clearances before ordering. Also account for grab-bar placement, nearby fixtures, and the path from the doorway; the toilet cannot solve a layout problem on its own.

Confirm rough-in and plumbing before choosing a style

The rough-in measurement is the distance from the finished wall to the center of the floor drain, and it can rule out a model before other features matter. A stated 12-inch rough-in, as on the DeerValley two-piece, is useful only if it matches the bathroom’s measurement and the finished wall condition. Check water-supply location, bolt spacing, and whether the existing flange is in good condition. Commercial flushometer bowls, including the Kohler Highcliff, need compatible flushometer equipment and plumbing; they are not direct replacements for ordinary tank toilets. If measurements or connection types are unclear, have a plumber verify them before purchase.

Choose a flush system for the household and plumbing

Dual-flush models offer separate flush choices, which may help households manage water use, while a single-flush design keeps operation familiar. The products in this roundup span 1.28 GPF models, dual-flush toilets, and the TOTO Drake’s stated 1.6 GPF system, so compare the complete flush setup rather than assuming every low-use option performs alike. Drain condition, waste-line configuration, and installation quality also affect real-world clearing. A power-flush feature may appeal to buyers who prioritize a forceful flush, but noise and maintenance preferences can differ. Ask whether the selected model’s flushing system is suitable for the home’s plumbing and whether replacement parts are readily available.

Balance cleaning access against repair preferences

A one-piece toilet has fewer exterior seams between tank and bowl, which can make routine wiping easier. Its integrated form may be heavier and less convenient to move or handle during installation, and a damaged component can affect the complete unit. A two-piece toilet separates tank and bowl, a familiar arrangement that can make some repairs more straightforward, though the joint needs cleaning. Seat design matters too: soft-close seats reduce slamming but may require model-specific replacement parts. Before choosing based on appearance, check the manufacturer’s parts support, seat availability, and the installer’s capacity to handle the unit.

Know when to pay for a specialized design

Paying more for a specialized flush system, surface coating, or one-piece body makes sense only when that feature addresses a real need. The TOTO Drake’s Tornado Flush and CEFIONTECT coating may appeal to buyers prioritizing bowl-cleaning features, while the Kohler Highcliff is aimed at commercial plumbing setups. Neither is automatically a better accessible choice than a simpler residential model. Extra-tall toilets also deserve a careful fit check: a 21-inch product may help some users, but height beyond the common comfort range can complicate transfers for others. Spend time comparing the exact dimensions, included seat, compatibility, and service needs before paying for a feature that may not improve daily use.

Frequently Asked Questions

Does a toilet labeled ADA or comfort height automatically meet accessibility requirements?

No. Product labels can describe a height category, but the toilet is only one part of an accessible installation. The finished seat height, clear floor space, grab bars, approach route, flush controls, and other room details may all matter under the applicable rules. Specifications can also refer to bowl height rather than height with the seat installed. I would check the exact product dimensions and have the full bathroom layout reviewed for the standards that apply to the project.

Should I choose a 17-inch toilet or a taller model such as the 21-inch SUPERFLO?

The right height depends on the primary user’s leg length, strength, balance, and transfer method. A 17-inch model is a common comfort-height choice, while a 21-inch toilet may feel more manageable to some users but too high for others. Confirm whether each listed measurement includes the seat, since that changes the final sitting height. If possible, compare the proposed height with a chair or existing toilet the user can sit on safely before ordering. For shared or regulated bathrooms, also check the applicable accessibility specification.

Can I replace my tank toilet with the Kohler Highcliff bowl?

Not as a simple like-for-like swap in most homes. The Highcliff is a flushometer bowl with a top spud, so it needs compatible flushometer hardware and the plumbing arrangement that supports that setup. A standard tank toilet uses a different supply and flushing configuration. Have a plumber check the water supply, wall or carrier setup, and installation requirements before treating it as an option. For an ordinary residential replacement, one of the tank-style models in this roundup is generally the more direct category to compare.

Is a one-piece toilet a better choice for an accessible bathroom than a two-piece toilet?

Neither construction style is inherently more accessible; height, clearances, bowl shape, and controls matter more. A one-piece design can reduce seams that collect grime, which may simplify exterior cleaning. It can also be heavier to handle, and some repairs may be less convenient. Two-piece models are more familiar to many installers and may offer easier access to separate tank components, though the tank-to-bowl joint needs care. Choose based on the user’s needs, the bathroom’s fit, and the repair support available for the specific model.

How can I tell whether an elongated toilet will fit without blocking access?

Measure the existing rough-in, the available front-to-back space, and the clearance around the toilet before selecting a bowl. Compare the manufacturer’s projection from the finished wall, not just the overall product height or width. Then mark the toilet footprint on the floor and check door movement, nearby fixtures, grab bars, and the user’s approach and transfer space. An elongated bowl may offer more seating area but can intrude farther into a compact room than a round bowl. If the bathroom must meet accessibility rules, verify the whole layout against the relevant clearance requirements.

Conclusion

For most buyers seeking a residential accessible-height toilet, I would start with the DeerValley ADA Two-Piece as the best overall choice because its listed height-focused design, elongated bowl, power flush, and 12-inch rough-in details make its use case easy to assess. For best value, compare the HOROW 17-Inch Comfort-Height Two-Piece with Dual Flush against the room’s measurements and the user’s needs; its dual-flush setup gives it a distinct practical role. The TOTO Drake is my best premium-leaning pick for shoppers who value its flush and bowl-coating features, while the straightforward two-piece DeerValley is the best starting point for beginners comparing specifications. For a compact room, look at the BAYROLL round-bowl model; for easier exterior wiping, compare the one-piece Casta Diva or DeerValley choices; and for commercial plumbing, consider the Kohler Highcliff only after compatibility checks. Before deciding, confirm the actual seat height, rough-in, clearances, and applicable accessibility requirements.
