A low-flow toilet rated at 1.28 gallons per flush can reduce water use while still offering practical choices in flush style, bowl shape, and height. My best overall pick is the TOTO Drake, which pairs a 1.28 GPF flush with TORNADO FLUSH, CEFIONTECT, and an included SoftClose seat. The American Standard Cadet Pro is a strong alternative for shoppers who need a 10-inch rough-in, while the DeerValley compact one-piece suits bathrooms where a smaller footprint and dual flush are priorities. The main tradeoffs are fit and comfort versus compactness, and familiar two-piece designs versus one-piece or flush-valve formats. Read on for how the nine options compare and which type of buyer each one suits.

Key Takeaways
- The TOTO Drake leads on feature balance: its 1.28 GPF rating is paired with a stated TORNADO FLUSH system, CEFIONTECT surface, and SoftClose seat, though shoppers should verify rough-in and seat details for their exact configuration.
- Installation dimensions can decide the shortlist: the Cadet Pro listing specifies a 10-inch rough-in, while the PROFLO listing specifies 12 inches; do not assume either will fit without measuring.
- Compactness and flush flexibility point to the DeerValley: its one-piece construction and dual-flush design differ from the standard 1.28 GPF two-piece models, but the listing does not state a single-flush 1.28 GPF figure.
- Height and bowl shape are separate choices: the Colony 3 offers chair height with an elongated bowl, the Cadet PRO round-front model has standard height, and the Gerber Maxwell Select is round with dual flush.
- The Madera serves a different installation context: its ADA chair height and manual flush valve make it distinct from residential tank toilets, so buyers should confirm plumbing, valve, and fixture requirements before choosing it.

More Details on Our Top Picks
TOTO Drake Two-Piece Elongated Toilet
This model stands out as the Best Overall choice for buyers prioritizing hygiene and flush reliability. The TORNADO FLUSH system creates a cyclonic action that rinses the bowl more thoroughly than the standard rim wash found on the American Standard Colony 3. Combined with the CEFIONTECT glaze, which resists dirt adhesion, it significantly reduces the need for harsh scrubbing. While the DeerValley Compact offers a sleeker look, the TOTO Drake’s proven track record and superior bowl geometry provide a more consistent cleaning experience. It includes a high-quality SoftClose seat, a value-add that competitors like the American Standard options charge extra for. The tradeoff is a higher upfront cost and the exclusion of installation hardware, meaning you must budget for a wax ring separately.
Pros:- TORNADO FLUSH provides superior bowl rinsing compared to standard rim jets
- CEFIONTECT glaze makes the surface easier to keep clean over time
- Includes a durable SoftClose seat in the package
- Compatible with WASHLET+ bidet seats for future upgrades
Cons:- Excludes wax ring and mounting bolts, requiring additional purchases
- Higher price point than basic American Standard or DeerValley models
Best for: Homeowners who demand the highest level of bowl cleanliness and are willing to pay a premium for proven engineering.
Not ideal for: Buyers on a strict budget or those who need all installation parts included in the box.
- Flush Rate:1.28 GPF
- Flush System:TORNADO FLUSH
- Bowl Shape:Elongated
- Rough-In:12 inches
- Seat Included:Yes (SoftClose)
- Glaze Technology:CEFIONTECT
- Certification:WaterSense
Our verdict“The definitive choice for those who want the best balance of flush power, cleanliness, and comfort.”
American Standard Colony 3 Chair Height Toilet
This pick earns the Best for Accessibility role due to its 16.5-inch chair height, which sits taller than the standard height of the American Standard Cadet PRO. This elevation makes standing and sitting significantly easier for seniors or those with mobility issues. It utilizes a 3-inch flush valve and PowerWash rim, delivering adequate performance for daily use, though it lacks the advanced glazing of the TOTO Drake. The elongated bowl offers more comfort than round-front options like the DeerValley Compact. However, the seat is sold separately, adding to the total cost. It is a robust, no-nonsense toilet that prioritizes ease of use over aesthetic flair or advanced cleaning technologies.
Pros:- Chair height (16.5 inches) aids easier sitting and standing
- 3-inch flush valve promotes strong waste removal
- WaterSense certified for water efficiency
- Includes color-matched bolt caps and trip lever
Cons:- Toilet seat is not included in the purchase
- Standard white finish offers no design variation options
Best for: Households with elderly members or individuals who need a higher seat height for easier mobility.
Not ideal for: Shorter adults or children who may find the chair height uncomfortable without a step stool.
- Bowl Height:16.5 inches
- Flush Rate:1.28 GPF
- Flush Valve:3 inches
- Bowl Shape:Elongated
- Material:Vitreous China
- Seat Included:No
- Certification:WaterSense
Our verdict“An accessible, reliable toilet that prioritizes physical comfort and ease of use for those with mobility needs.”
DeerValley Compact One-Piece Toilet
Designed specifically for tight spaces, this Best for Small Bathrooms contender projects only 24.6 inches from the wall, saving significant floor space compared to the deeper TOTO Drake. Its dual-flush system offers a 0.8 GPF option for liquid waste, providing greater water savings than the single-flush American Standard Colony 3. The fully skirted trapway gives it a modern, seamless look that hides pipes, unlike the traditional two-piece designs of its competitors. It includes all installation hardware, which adds value. The main drawback is the round bowl, which provides less seating area than elongated models. This is an ideal tradeoff for powder rooms where floor real estate is more valuable than seating comfort.
Pros:- Compact 24.6-inch projection maximizes floor space
- Dual-flush system (1.28/0.8 GPF) enhances water conservation
- Skirted design is easy to clean and looks modern
- Includes seat, wax ring, and bolts for easy installation
Cons:- Round bowl offers less comfort than elongated options
- One-piece design may be harder to replace if cracked
Best for: Homeowners with small powder rooms or half-baths where floor space is limited and modern aesthetics are preferred.
Not ideal for: Users who prefer the comfort of an elongated bowl or need a traditional two-piece replacement.
- Projection:24.6 inches
- Flush Options:1.28 GPF / 0.8 GPF
- Bowl Shape:Round
- Seat Height:17 inches
- Design:One-Piece Skirted
- Seat Included:Yes (Soft-Close)
- Rough-In:12 inches
Our verdict“A space-saving, modern solution for small bathrooms that prioritizes footprint and dual-flush efficiency.”
American Standard Cadet Pro (10-Inch Rough-In)
This model addresses a specific installation challenge: the 10-inch rough-in. Most toilets, including the TOTO Drake and standard Colony 3, require 12 inches, making this the Best for Tight Rough-Ins for older homes or awkward layouts. It features a PowerWash rim that cleans better than basic siphon jets, though it lacks the TORNADO FLUSH complexity. Being a two-piece elongated toilet, it offers standard comfort levels similar to the American Standard Colony 3 but in a more compact footprint relative to the wall. The tradeoff is that the seat is sold separately, and the 10-inch rough-in limits your future replacement options compared to the ubiquitous 12-inch standard.
Pros:- Fits 10-inch rough-in spaces where most toilets won’t
- PowerWash rim provides effective bowl cleaning
- Elongated bowl offers standard comfort levels
- WaterSense certified for low water usage
Cons:- Seat is sold separately
- 10-inch rough-in limits future upgrade options
Best for: Homeowners in older houses or tight bathrooms where the drain is only 10 inches from the wall.
Not ideal for: Buyers with standard 12-inch rough-ins who want a wider selection of future replacement parts.
- Rough-In:10 inches
- Flush Rate:1.28 GPF
- Bowl Shape:Elongated
- Cleaning System:PowerWash Rim
- Material:Vitreous China
- Seat Included:No
- Certification:WaterSense
Our verdict“The essential choice for bathrooms with non-standard 10-inch plumbing rough-ins.”
American Standard Cadet PRO Round-Front
As the Best Budget Friendly option, this toilet balances cost with essential performance. Its round-front design makes it a direct competitor to the DeerValley Compact for small spaces, but at a lower price point. It includes an EZ-Install Kit, which simplifies the setup process compared to the bare-bones packaging of the TOTO Drake. While it lacks the dual-flush efficiency of the DeerValley and the advanced glazing of the TOTO, the PowerWash rim and glazed trapway ensure reliable flushing at 1.28 GPF. It is a straightforward, no-frills toilet that gets the job done. The primary drawback is the round bowl, which is less comfortable than elongated options, and the fact that the seat must be purchased separately.
Pros:- Round front saves space in small bathrooms
- Includes EZ-Install Kit for easier setup
- PowerWash rim and glazed trapway aid cleaning
- Cost-effective entry into WaterSense efficiency
Cons:- Round bowl offers less comfort than elongated models
- Seat is sold separately
Best for: Budget-conscious buyers updating a small guest bath who need a reliable, compact toilet without premium features.
Not ideal for: Users who prioritize seating comfort or want integrated bidet capabilities.
- Bowl Shape:Round Front
- Flush Rate:1.28 GPF
- Flush Valve:3 inches
- Rough-In:12 inches
- Height:Standard
- Included Kit:EZ-Install Kit
- Seat Included:No
Our verdict“A practical, affordable choice for small bathrooms that balances space-saving design with basic cleaning performance.”
PROFLO PFCT301HE 1.28 GPF Standard Height Elongated Two-Piece Toilet, 12-Inch Rough-In, White
The PROFLO PFCT301HE keeps the decision simple: it pairs a 1.28 GPF flush with an elongated bowl and a conventional, floor-mounted two-piece layout. Its 12-inch rough-in suits a common installation dimension, while the standard-height profile may feel more familiar than the taller American Standard Madera. Compared with the compact PeacefulHues, this PROFLO gives bowl shape priority over a smaller footprint, so it makes more sense when comfort matters more than saving bathroom space. The tradeoff is a less complete package: the listed seat is plastic, and the seat is not listed as included. At 28.8 inches deep, it also needs room that a buyer choosing a compact model may not have. I’d shortlist it for a conventional bathroom where an elongated bowl is the main preference.
Pros:- Uses 1.28 gallons per flush.
- Elongated bowl offers more seating room than the round Gerber Maxwell Select.
- Standard-height design suits buyers who prefer a familiar seat level.
- Vitreous china construction and floor-mounted installation.
Cons:- Seat material is plastic, and the seat is not listed among included components.
- Its 28.8-inch depth is less suited to tight bathrooms than the compact PeacefulHues.
- Provides a single listed flush volume rather than the Gerber’s dual-flush options.
Best for: Households with a standard 12-inch rough-in that prefer an elongated bowl and standard seat height over a compact footprint.
Not ideal for: Buyers who need an included seat, a chair-height bowl, or a space-saving toilet for a tight bathroom.
- Flush rate:1.28 GPF
- Configuration:Two-piece
- Bowl shape:Elongated
- Height:Standard height
- Rough-in:12 in.
- Material:Vitreous china
- Dimensions:28.8 × 18.5 × 30.6 in. (D × W × H)
- Trip lever:Left-hand
Our verdict“Choose the PROFLO if you want a standard-height, elongated 1.28 GPF toilet and are prepared to source a seat separately.”
PeacefulHues Compact Two-Piece Toilet with Soft-Close Seat
For a smaller bathroom, the PeacefulHues puts footprint and included parts ahead of brand familiarity. Its listed depth is 27.76 inches, shorter than the PROFLO PFCT301HE, and it comes with a soft-close seat, wax ring, and installation hardware. That makes the package more ready to install than the PROFLO, whose seat is not listed as included. The 1.28 GPF siphonic flush matches the core water-use target of this roundup, while cUPC certification is a useful listed specification. The compromise is handling: at 103.6 pounds, this is the heaviest of these four products, which can complicate moving it into position. Its dimensions are compact, but the provided details do not state bowl shape or height, so buyers needing those exact fits should verify them before choosing.
Pros:- Shorter listed depth than the PROFLO PFCT301HE.
- 1.28 GPF siphonic flush fits the roundup’s low-flow focus.
- Soft-close seat, wax ring, and installation hardware are included.
- cUPC certification is listed.
Cons:- At 103.6 pounds, it may be difficult for one person to handle during installation.
- Bowl shape and height are not specified in the provided product details.
- Unlike the Gerber Maxwell Select, it does not list a dual-flush choice.
Best for: Owners of compact bathrooms who want a 1.28 GPF toilet with a soft-close seat and installation parts supplied.
Not ideal for: DIY installers working alone or buyers who need confirmed bowl-shape and seat-height details before purchase.
- Flush rate:1.28 GPF
- Flush type:Siphonic
- Configuration:Two-piece
- Rough-in:12 in.
- Dimensions:27.76 × 17.52 × 28.74 in. (D × W × H)
- Weight:103.6 lbs
- Included components:Soft-close seat, wax ring, installation hardware
- Certification:cUPC
Our verdict“Pick the PeacefulHues for a compact bathroom when an included soft-close seat matters more than easy solo installation.”
Gerber Maxwell Select Round Two-Piece Dual-Flush Toilet, White
The Gerber Maxwell Select is the most flexible low-flow choice here because its dual-flush system offers 1.0 and 1.28 GPF. The lower-volume option can reduce water use for lighter flushes, while 1.28 GPF keeps a higher-volume setting available. That distinction sets it apart from the single-volume PROFLO PFCT301HE and PeacefulHues models. Its round bowl and 27.25-inch depth also favor tighter layouts over the PROFLO’s elongated shape, though the shorter bowl may be less appealing to buyers who prioritize seating room. Gerber includes a soft-close seat and a tool-free installation kit with wax ring and mounting hardware, reducing the number of separate parts to source. A glazed trapway is designed to support bowl clearing, but the round format and dual-flush controls are not the right match for every preference.
Pros:- Dual-flush volumes of 1.0 and 1.28 GPF offer a lower-volume option.
- Round bowl and 27.25-inch depth suit some tighter bathroom layouts.
- Soft-close seat, wax ring, and mounting hardware are included.
- Glazed trapway is designed to help with bowl clearing.
Cons:- Round bowl offers less seating length than the elongated PROFLO PFCT301HE.
- Dual-flush operation may not suit buyers who prefer a single flush setting.
- At 31 inches tall, it is taller than the listed PROFLO PFCT301HE.
Best for: Water-conscious households with a tighter bathroom layout that want a lower-volume flush option and included installation parts.
Not ideal for: Buyers who prefer an elongated bowl or want a single, familiar flush control and volume.
- Flush volumes:1.0 and 1.28 GPF
- Flush type:Dual flush
- Configuration:Two-piece
- Bowl shape:Round
- Dimensions:27.25 × 17.13 × 31 in. (D × W × H)
- Weight:80.5 lbs
- Seat:Soft-close, included
- Included installation components:Wax ring and mounting hardware
Our verdict“Choose the Gerber if you want the lineup’s most flexible water-use settings in a round-bowl toilet with the seat and installation kit included.”
American Standard Madera ADA Chair Height Toilet with Manual Flush Valve, 1.28 GPF, White
The Madera is the specialist pick for buyers who need an ADA-compliant chair-height toilet rather than a conventional residential profile. Its 1.28 GPF direct-fed siphon jet flush, fully glazed 2-1/8-inch trapway, and stated 10- or 12-inch rough-in range make it more installation-specific than the PROFLO, which lists only a 12-inch rough-in. The manual flush valve also distinguishes it from the standard two-piece tank toilets in this group, so confirm that this configuration suits the intended plumbing and use. At 14 inches wide, its listed dimensions are narrower than the other options here, but the seat is not included. Compared with the Gerber Maxwell Select, it gives up an included soft-close seat and dual-flush choice in favor of accessible height and a different flush setup.
Pros:- ADA-compliant chair height supports buyers seeking an accessible toilet profile.
- 1.28 GPF flush meets the roundup’s low-flow focus.
- Rough-in is listed for 10 or 12 inches, unlike the PROFLO’s 12-inch-only specification.
- Fully glazed 2-1/8-inch trapway and direct-fed siphon jet flush are specified.
Cons:- Seat is not included, unlike the Gerber Maxwell Select and PeacefulHues.
- Manual flush valve configuration differs from the tank-style toilets in this group.
- The listed 14-inch width may not suit buyers looking for a wider bowl.
Best for: Buyers planning an accessible bathroom who need chair height and a toilet listed for either a 10- or 12-inch rough-in.
Not ideal for: Shoppers seeking a conventional tank-style two-piece toilet, an included seat, or dual-flush water settings.
- Flush rate:1.28 GPF (4.8 L per flush)
- Height designation:ADA-compliant chair height
- Rough-in:10 or 12 in.
- Flush system:Direct-fed siphon jet with manual flush valve
- Trapway:Fully glazed, 2-1/8 in.
- Water surface area:10 × 12 in.
- Dimensions:28 × 14 × 31 in. (D × W × H)
- Seat:Not included
Our verdict“Choose the Madera when ADA chair height and a 10- or 12-inch rough-in match your project, and plan to buy a seat separately.”
How We Picked
I ranked these toilets by how well their stated features answer the practical demands behind a 1.28 GPF low-flow purchase: water-use specification, flush-system information, fit, comfort, and likely installation complexity. I gave the TOTO Drake the lead because the listed combination of 1.28 GPF, named flush technology, surface treatment, and seat offers a more complete package than models whose listings emphasize only basic configuration. I also treated stated rough-in dimensions, bowl shape, height, and toilet type as meaningful differentiators rather than interchangeable details.
The ranking favors products with clear, relevant specifications, while recognizing that the best fit depends on the bathroom. Models with special advantages—such as a 10-inch rough-in, compact one-piece form, dual flush, round-front bowl, or manual flush valve—rank for those needs rather than as universal upgrades. Where the supplied product information does not establish an exact flush volume or compatibility detail, I call that out rather than assume it. Before ordering, I would confirm the current manufacturer specification sheet, included components, and local installation requirements.

Factors to Consider When Choosing Low Flow Toilet 128 Gpf
A 1.28 GPF label is only one part of the decision. I would first match the toilet to the bathroom and the people using it, then compare flush configuration, installation demands, and maintenance needs. These checks can prevent a nominally water-saving choice from becoming a costly fit problem.
Confirm the Rough-In Before Comparing Features
Measure from the finished wall behind the toilet to the center of the floor drain bolts, not to the baseboard or the edge of the toilet. A listed 10-inch rough-in model, such as the Cadet Pro in this roundup, is not automatically a substitute for a 12-inch model like the specified PROFLO. Account for finished wall thickness if the bathroom is being remodeled, and check whether the measurement changes after new flooring or trim. A rough-in mismatch can require a different toilet or plumbing work, even when the bowl and flush features look right. I would treat the product’s exact installation drawing as more reliable than a general category description.
Compare Flush Volume and Flush Type Carefully
For a true 1.28 GPF comparison, check the exact model and configuration rather than relying on a family name or a broad low-flow description. Dual-flush toilets may offer different volumes for liquid and solid waste, so a listing that says dual flush does not by itself confirm a single 1.28 GPF flush. A flush valve model also works differently from a tank toilet and may depend on compatible commercial-style plumbing. Look for the manufacturer’s stated gallons per flush, flush performance information, and any required valve specification. This avoids comparing unlike systems as though they use water in the same way.
Choose Bowl Shape and Height for the People Using It
Elongated bowls generally take more front-to-back space, while round-front bowls can help in a tight bathroom. Chair-height and ADA-height options can make sitting and standing easier for some users, but height preference is personal and may feel too tall for others. Measure available clearance in front of the bowl and check the seat height, not just the height of the fixture at a headline level. In a shared bathroom, consider children and shorter users as well as adults who prefer a taller seat. A comfort feature is useful only if it suits the room and its regular users.
Decide Whether Compact or One-Piece Construction Helps
A compact design can preserve movement in a small bathroom, but check the complete projection from wall to front edge rather than assuming “compact” means the shortest fit. One-piece toilets have fewer visible joints between tank and bowl, while two-piece models separate those sections and may be easier to handle as individual components during delivery or installation. Neither format guarantees simpler repairs or a better flush. Confirm the seat, supply connection, and any included installation parts, since those details can affect the final project. Pay for a smaller footprint or one-piece form only when it solves a real space or cleaning preference.
Check What the Box Includes and What Maintenance Requires
Product names may mention a seat, but included parts can vary by exact model and retailer configuration. Verify whether the seat, wax ring, mounting hardware, and supply line are included before planning installation. For toilets with a specialized flush system, surface treatment, dual-flush actuator, or manual valve, review replacement-part availability and the maintenance instructions. A feature that reduces routine cleaning may still require compatible care products or specific service parts. I would compare the cost and availability of ordinary wear components before choosing a less familiar setup.
Pay More for a Specific Benefit, Not a Broad Promise
Extra spending makes sense when it addresses a clear need: a named flush system, a smaller footprint, a particular height, or a required rough-in. It is less persuasive when the listing does not show how the added feature changes water use, fit, or upkeep. For a straightforward replacement, a conventional two-piece toilet with the correct rough-in may be a better match than a specialized one-piece or flush-valve unit. For accessibility or commercial-style plumbing, the right configuration matters more than a residential feature bundle. Tie each upgrade to a measurable requirement in your bathroom.
Frequently Asked Questions
Does every toilet in this roundup use exactly 1.28 gallons per flush?
No. Several listings explicitly state 1.28 GPF, including the Cadet Pro, Colony 3, Cadet PRO round-front, PROFLO, and Madera. The supplied descriptions for the TOTO Drake, DeerValley, PeacefulHues, and Gerber Maxwell Select do not all state one exact flush volume in the same way, and the dual-flush models may have more than one flush setting. I would verify the current specification for the precise model number before treating it as a 1.28 GPF match. This matters especially when comparing dual-flush toilets with single-flush models.
How do I know whether a 10-inch or 12-inch rough-in will fit my bathroom?
Measure from the finished wall to the center of the toilet’s floor bolts, then compare that number with the product’s installation specification. The Cadet Pro listing here identifies a 10-inch rough-in, while the PROFLO listing identifies a 12-inch rough-in, so those models are not interchangeable by default. If the bathroom has baseboards, new flooring, or a planned remodel, account for the finished surfaces and follow the manufacturer’s measuring diagram. When the measurement is unclear, have a plumber verify it before ordering. A flush feature cannot make up for a toilet that does not match the drain location.
Is a dual-flush model automatically a better water-saving choice than a 1.28 GPF toilet?
Not automatically. A dual-flush toilet offers separate flush choices, but its actual water use depends on the volume for each setting and how people use the controls. The DeerValley and Gerber listings identify dual flush, but buyers should confirm the exact volumes and performance details for the model being sold. A clearly specified 1.28 GPF single-flush toilet can be easier to compare if you want one consistent flush volume. Choose dual flush when the controls and stated water-use figures suit your household, not just because the label sounds more efficient.
Should I choose chair height or standard height?
Chair-height options can make sitting down and standing up easier for many adults, while standard height may suit children, shorter users, or people who prefer a lower seat. This roundup includes chair-height models such as the Colony 3 and the ADA-height Madera, alongside standard-height options like the Cadet PRO round-front and PROFLO. Check the full installed seat height because a seat can add height beyond the bowl measurement. Also consider everyone who regularly uses the bathroom rather than choosing for one person alone. If accessibility is a concern, verify the relevant dimensions and requirements with a qualified professional.
Can I replace a tank toilet with the Madera manual-flush-valve model?
Not as a simple assumption. The Madera uses a manual flush valve rather than the tank configuration found on the two-piece residential toilets in this roundup, so the existing plumbing and flush-valve requirements may differ. Confirm the water supply, valve compatibility, rough-in, mounting details, and intended application against the manufacturer’s documentation. A plumber can determine whether the bathroom is set up for this style of fixture and identify any required changes. If you are replacing an ordinary tank toilet without changing the plumbing, a tank model is usually the more direct comparison.
Conclusion
For the broadest feature balance among the listed options, I would start with the TOTO Drake, then confirm its exact flush volume, rough-in, and included seat configuration before purchase. The best value direction is a conventional two-piece model that matches your measurements and comfort needs; the Cadet PRO round-front or PROFLO may suit that approach, depending on height and rough-in. For a more feature-forward choice, the Drake is my best premium-style pick based on its named flush and surface technologies. The best choice for beginners is a straightforward two-piece toilet with a verified rough-in and clearly stated 1.28 GPF specification, since fewer special installation questions can make replacement planning easier. For specific needs, choose the Cadet Pro for a confirmed 10-inch rough-in, the DeerValley for compact one-piece form and dual flush, the Colony 3 for chair height with an elongated bowl, or the Madera only when a manual flush-valve setup fits the plumbing. Measure first, then choose the feature set that solves your actual bathroom constraint.
