Among Swiss Madison toilets, my best overall pick is the St. Tropez One-Piece Elongated Toilet with Dual Flush and a 10-inch rough-in, since it pairs a space-specific fit with an elongated bowl and water-saving flush choices. The Sublime II Round is a better match for smaller bathrooms, while the Casta Diva Comfort Height models focus on easier sitting and standing. The main tradeoffs are fit, bowl shape, seat height, and whether a distinctive finish is worth narrowing your options. Rough-in dimensions matter especially: a toilet that does not match the existing plumbing can complicate installation. Read on for the full comparison and advice on choosing among these 13 models.

Key Takeaways
- Rough-in fit changes the shortlist: the lineup includes 10-inch models, a 12-inch Sublime II, and a 14-inch St. Tropez, so measure before choosing by appearance.
- The St. Tropez is the most adaptable family: it appears in multiple rough-in sizes, comfort-height styling, and finishes, giving it more ways to suit a bathroom than the more specialized options.
- The Sublime II favors tighter spaces: its round bowl is the clear alternative to the elongated St. Tropez and Casta Diva when bathroom clearance matters.
- Comfort height is a fit preference, not a universal upgrade: Casta Diva and St. Tropez comfort-height versions may suit adults who prefer a higher seat, but can feel too tall for some users.
- Finish and shape carry practical tradeoffs: matte or glossy black and square-bowl designs make a stronger visual statement than white elongated models, but are less conventional choices for matching and replacement.

More Details on Our Top Picks
Swiss Madison St. Tropez One-Piece Elongated Toilet with Dual Flush and 10-Inch Rough-In
I’d put this St. Tropez first for shoppers whose existing plumbing has a 10-inch rough-in: that fit is its defining advantage over the 12-inch St. Tropez models, including the black-hardware version. Its 1.1/1.6-gpf dual flush gives buyers a lower-volume option for liquid waste, while the elongated bowl offers more room than the round-bowl Sublime II models elsewhere in this roundup. The skirted trapway and quick-release seat also reduce the awkward surfaces around the base and seat hinges when cleaning. The tradeoffs are practical: it is a heavy, 110-pound one-piece unit, and its standard-height design is not the pick for someone seeking a taller seat. I’d verify the rough-in before buying; the otherwise similar 12-inch models will not solve a 10-inch fit problem.
Pros:- 10-inch rough-in suits installations that the 12-inch St. Tropez models cannot match
- Dual flush offers 1.1- and 1.6-gpf options
- Elongated bowl provides more room than round-bowl alternatives
- Skirted trapway and quick-release, soft-close seat simplify routine cleaning
Cons:- The 10-inch rough-in limits compatibility with more common 12-inch layouts
- At 110 pounds, the one-piece unit can be difficult to position during installation
- Standard height may be less comfortable for buyers seeking an elevated seat
Best for: Homeowners replacing a toilet in a bathroom with a confirmed 10-inch rough-in who want an elongated bowl and dual-flush operation.
Not ideal for: Buyers with a 12-inch or 14-inch rough-in, or anyone who needs a comfort-height seat or a lighter toilet for easier handling.
- Model:SM-1T274
- Rough-in:10 inches
- Flush:Dual flush, 1.1/1.6 gpf
- Bowl shape:Elongated
- Height:Standard, 15–17 inches
- Material and finish:Ceramic, glossy white
- Dimensions:27 x 15.15 x 31.2 inches
- Weight and installation:110 pounds; floor mounted
Our verdict“Choose this St. Tropez when your bathroom needs a 10-inch rough-in and you want an elongated, dual-flush toilet; skip it if your layout calls for 12 inches or a taller seat.”
Swiss Madison St. Tropez One-Piece Elongated Toilet, 14-Inch Rough-In, Dual Flush, Glossy White
This St. Tropez earns a distinct place for bathrooms with a 14-inch rough-in, a less flexible fit than the 12-inch St. Tropez with black hardware but a direct match for the right existing plumbing. It keeps the lineup’s useful combination of an elongated bowl, skirted exterior, and 1.1/1.6-gpf dual flush. The seat’s quick-release feature helps with cleaning around the hinges, while soft-close operation avoids a hard seat drop. Compared with the 10-inch St. Tropez, this model serves the opposite installation need; neither should be treated as a general replacement without measuring first. At 108.3 pounds, it also calls for careful handling, and its specialized rough-in may require plumbing changes in a standard 12-inch bathroom. I’d choose it for a confirmed 14-inch layout, not for its finish alone.
Pros:- 14-inch rough-in serves a specific layout not covered by the other St. Tropez options here
- Dual-flush choices use 1.1 or 1.6 gallons per flush
- Elongated bowl and skirted trapway pair comfort with a cleaner exterior
- Soft-close, quick-release seat makes seat removal and cleaning easier
Cons:- The 14-inch rough-in is incompatible with many standard 12-inch installations
- Its 108.3-pound weight can complicate delivery and installation
- One-piece construction leaves less flexibility for handling than a two-piece toilet
Best for: Owners of bathrooms with a measured 14-inch rough-in who want a white, elongated one-piece toilet with dual flush.
Not ideal for: Shoppers with standard 12-inch or 10-inch rough-ins, or those who want an installation that is easier to handle without help.
- Model:SM-1T251
- Rough-in:14 inches
- Flush:Dual flush, 1.1/1.6 GPF
- Bowl shape:Elongated
- Material and finish:Ceramic, glossy white
- Dimensions:27.35 x 15.75 x 30.3 inches
- Weight and installation:108.3 pounds; floor mounted
- Seat:Plastic, soft-close, quick-release
Our verdict“Buy this model when your measured rough-in is 14 inches; for a standard 12-inch layout, the St. Tropez with black hardware is a closer fit.”
Swiss Madison St. Tropez One-Piece Elongated Dual-Flush Toilet, Matte Black
Among these five, this is the clear choice for buyers who want the toilet itself to contribute to a dark, high-contrast bathroom scheme. Its matte-black ceramic finish sets it apart from the white St. Tropez models, while the 12-inch rough-in matches the standard layout that the 10- and 14-inch versions do not. Functionally, it shares the family’s elongated bowl, skirted trapway, and 1.1/1.6-gpf dual flush, so the main compromise is aesthetic rather than a different flushing setup. Compared with the white St. Tropez with black hardware, this model makes a bolder statement but gives up the familiar white-fixture look and its easier coordination with many bathrooms. It is also a 110-pound, standard-height unit, so buyers seeking easier installation or an elevated seat should look at other options.
Pros:- Matte-black finish gives it a distinctive look compared with the white St. Tropez models
- 12-inch rough-in suits standard-layout replacements
- Dual flush provides 1.1- and 1.6-gpf options
- Skirted trapway and quick-release, soft-close seat support easier cleaning
Cons:- Matte-black ceramic is a less versatile match for bathrooms built around white fixtures
- At 110 pounds, installation may require extra help
- Standard-height design may not suit buyers who prefer a taller seat
Best for: Renovators designing a dark or contemporary bathroom who have a 12-inch rough-in and want a matte-black toilet rather than black accents on white ceramic.
Not ideal for: Buyers seeking a traditional white fixture, a comfort-height seat, or a lighter unit to install with less effort.
- Model:SM-1T254MB
- Rough-in:12 inches
- Flush:Dual flush, 1.1/1.6 gpf
- Bowl shape:Elongated
- Color and material:Matte black ceramic
- Dimensions:27 x 15.15 x 31.5 inches
- Weight and installation:110 pounds; floor mounted
- Seat and warranty:Soft-close, quick-release seat; 1-year limited warranty
Our verdict“Choose this St. Tropez for a deliberate matte-black look with a standard 12-inch fit, but pick the black-hardware white model if you want a lighter visual contrast.”
Casta Diva One-Piece Elongated Toilet with 17.5-Inch Comfort Height
The Casta Diva is the strongest fit here for buyers prioritizing a 17.5-inch comfort-height seat and lower listed flush volumes. Its 1.0-gpf liquid and 1.28-gpf solid settings use less water per flush than the 1.1/1.6-gpf choices on the Swiss Madison St. Tropez models. The siphon jet flush and fully glazed trapway are useful design details, while the skirted one-piece body and quick-release seat keep cleaning access straightforward. This is a different proposition from the St. Tropez with black hardware: the Casta Diva emphasizes seat height and flush rate rather than finish accents. The tradeoff is that the product is outside the Swiss Madison brand focus of this roundup, and its 12-inch rough-in and heavy one-piece form still demand a compatible layout and careful installation.
Pros:- 17.5-inch seat height suits buyers who want a taller sitting position
- Flush volumes are 1.0 GPF for liquids and 1.28 GPF for solids
- Fully glazed trapway and skirted body support easier cleaning
- Soft-close, quick-release seat is included
Cons:- It is a Casta Diva model rather than a Swiss Madison toilet
- Requires a 12-inch rough-in
- Heavy one-piece construction can make installation more demanding
Best for: Buyers who prefer a 17.5-inch seat, want lower listed flush volumes, and have a standard 12-inch rough-in.
Not ideal for: Shoppers specifically seeking a Swiss Madison-branded toilet, or those with a non-12-inch rough-in or limited ability to handle a bulky one-piece unit.
- Model:CD-T006
- Rough-in:12 inches
- Flush:Dual flush: 1.0 GPF for liquids; 1.28 GPF for solids
- Maximum performance:MAP 1000 g
- Bowl and seat height:Elongated; 17.5-inch seat height
- Dimensions:25.39 x 14.56 x 26.57 inches
- Seat:Soft-close, quick-release PP seat
- Certification and warranty:CUPC; WaterSense criteria stated; 1-year limited customer service and lifetime technical consulting
Our verdict“Pick the Casta Diva over the St. Tropez models if seat height and lower listed flush volumes matter more to you than staying with the Swiss Madison brand.”
Swiss Madison St. Tropez One-Piece Elongated Toilet with Dual Flush and Black Hardware
This is the most balanced St. Tropez option for a standard 12-inch bathroom when buyers want a comfort-height seat without choosing a fully black fixture. Its glossy white ceramic body keeps the room feeling familiar, while the black hardware adds a restrained accent; that makes it less visually committed than the matte-black St. Tropez. The 1.1/1.6-gpf dual flush and elongated bowl match the broader St. Tropez formula, but the listed 17–19-inch height gives it a practical advantage over the standard-height 10-inch and matte-black models. Its included installation components are helpful, though the 108.5-pound weight still means careful positioning. I’d choose it for a taller seat and black details; buyers seeking lower flush volumes should compare the Casta Diva’s stated 1.0/1.28-gpf settings.
Pros:- Comfort-height design can make sitting down and standing up easier
- White ceramic with black hardware offers a subtler look than the matte-black St. Tropez
- Dual flush provides 1.1- and 1.6-gpf options
- Includes seat and listed installation components
Cons:- Requires a standard 12-inch rough-in
- At 108.5 pounds, it can be challenging to position during installation
- Flush volumes are higher than the Casta Diva’s stated 1.0/1.28-gpf settings
Best for: Homeowners with a 12-inch rough-in who want a taller, elongated toilet with a white finish and black hardware accents.
Not ideal for: Buyers with a 10-inch or 14-inch rough-in, or those who want a fully matte-black fixture or the lower listed flush volumes of the Casta Diva.
- Model:SM-1T254HB
- Rough-in:12 inches
- Flush:Dual flush, 1.1/1.6 gpf
- Bowl shape and height:Elongated; comfort height, 17–19 inches
- Material and finish:Ceramic; white with black hardware
- Dimensions:27.1 x 15.35 x 31.2 inches
- Weight and installation:108.5 pounds; floor mounted
- Included components:Seat, flush valve, fill valve, push button, wax ring and bolt kit, hardware, and manual
Our verdict“Choose this model for a comfort-height St. Tropez in white with black accents; the matte-black version suits a bolder finish, while the Casta Diva lists lower flush volumes.”
Swiss Madison Sublime II One-Piece Round Toilet, 12-Inch Rough-In, Dual Flush, Glossy White
The Sublime II with a 12-inch rough-in is a practical fit for bathrooms with a standard layout where a compact round bowl matters more than extra seating room. Its 1.1/1.6 GPF dual flush lets you choose a lower-volume flush for liquid waste, while the skirted trapway hides the exterior contours that can collect dust. Compared with the elongated Swiss Madison Ivy, this version takes up less front-to-back space but gives up some bowl room. The included soft-close, detachable seat and installation components make it a more complete package, though its standard-height seat may not suit buyers who prefer easier sitting and standing. I’d shortlist it for a compact bathroom with a confirmed 12-inch rough-in, but not for someone prioritizing an elongated bowl or taller seat.
Pros:- Dual-flush options offer 1.1 and 1.6 GPF choices
- Skirted, fully glazed trapway is designed to simplify exterior cleaning
- Soft-close seat detaches for cleaning
- Includes a wax ring and mounting hardware
Cons:- Standard-height design may be less comfortable for people who prefer a taller seat
- Round bowl offers less seating room than the elongated Swiss Madison Ivy
- The 12-inch rough-in limits fit in bathrooms built for other rough-in measurements
Best for: Homeowners with a standard 12-inch rough-in who want a compact, easy-to-clean one-piece toilet and dual-flush options.
Not ideal for: Buyers who need a taller seat, prefer an elongated bowl, or have a rough-in other than 12 inches.
- Model:SM-1T257
- Rough-in:12 inches
- Flush options:1.1 GPF and 1.6 GPF
- Bowl shape:Round
- Dimensions:24 × 14 × 29 inches (D × W × H)
- Material and finish:Ceramic, glossy white
- Installation:Floor-mounted
- Included components:Tank, bowl, seat, wax ring, bolt kit, and cover caps
- Warranty:1-year limited
Our verdict“Choose this Sublime II when a compact round bowl and 12-inch rough-in fit your bathroom better than the Ivy’s elongated profile.”
Swiss Madison Sublime II One-Piece Round Toilet, 10-Inch Rough-In, Dual Flush, Glossy White
This 10-inch rough-in Sublime II fills a specific need: it keeps the compact round bowl and skirted one-piece design of its 12-inch counterpart for a bathroom where the plumbing measurement calls for a shorter rough-in. The 1.1/1.6 GPF dual flush gives it the same two-volume approach, and its quick-release, soft-close seat is convenient for routine cleaning. Compared with the 12-inch Sublime II, the meaningful difference is fit, not a larger bowl or a richer feature set; measure before choosing, since this model is intended for a 10-inch rough-in. At 89 pounds, it can also be cumbersome to position, especially in a tight bathroom. I’d choose it when the rough-in matches and skip it if a standard 12-inch model would fit without plumbing changes.
Pros:- 10-inch rough-in suits bathrooms that cannot take a standard 12-inch model
- Dual-flush system offers 1.1 and 1.6 GPF options
- Skirted design conceals plumbing and is designed for easier cleaning
- Includes a soft-close, quick-release seat
Cons:- Requires a 10-inch rough-in, so it is not a general replacement for a 12-inch toilet
- At 89 pounds, installation and positioning may require extra help
- Round bowl provides less seating space than elongated options such as the Swiss Madison Ivy
Best for: Renovators replacing a toilet in a bathroom with a measured 10-inch rough-in who want a round, dual-flush one-piece model.
Not ideal for: Buyers with a 12-inch rough-in, those who want an elongated bowl, or anyone planning to move and position the toilet without help.
- Model:SM-1T277
- Rough-in:10 inches
- Flush options:1.1 GPF and 1.6 GPF
- Bowl shape:Round
- Dimensions:24 × 14 × 28.75 inches
- Weight:89 pounds
- Material and finish:Ceramic, glossy white
- Installation:Floor-mounted
- Included components:Toilet, hardware, bolts, bolt cover caps, seat, and lid
Our verdict“Pick this model only when your measured rough-in is 10 inches and you want the Sublime II’s compact round format.”
Swiss Madison Ivy One-Piece Dual-Flush Toilet (SM-1T112)
The Swiss Madison Ivy is the lineup’s better fit for buyers who want an elongated bowl without giving up the skirted one-piece look. Its longer profile offers more seating room than either round Sublime II, while the soft-close seat and skirted exterior support easier day-to-day care. The listing gives conflicting flush-volume figures: one section says 0.8/1.28 GPF, while another says 1.1/1.6 GPF. Warranty details also differ, so I would verify both with the seller before buying rather than assume a particular water use or coverage period. At 90 pounds and 27.5 inches deep, it also needs more handling and floor space than the round Sublime II. This is the comfort-oriented choice if you value an elongated bowl and can confirm the specifications.
Pros:- Elongated bowl provides more seating room than the round Sublime II models
- Skirted one-piece design reduces exposed exterior contours
- Soft-close seat is included
- Wax ring and hardware kit are included
Cons:- Product information conflicts on flush volumes, listing both 0.8/1.28 and 1.1/1.6 GPF
- Warranty information is inconsistent across the listing
- At 27.5 inches deep and 90 pounds, it needs more space and effort to install than the round Sublime II
Best for: Buyers with a 12-inch rough-in who prefer an elongated bowl and want a skirted one-piece design with a soft-close seat.
Not ideal for: Shoppers who need reliable published flush-volume or warranty details before purchase, or who have limited bathroom depth.
- Model:SM-1T112
- Rough-in:12 inches
- Flush options:Dual flush; listing conflicts between 0.8/1.28 GPF and 1.1/1.6 GPF
- Bowl shape:Elongated
- Dimensions:27.5 × 14 × 28 inches (D × W × H)
- Weight:90 pounds
- Material and finish:Ceramic, glossy white
- Installation:Floor-mounted
- Warranty:Listing states both a 1-year limited warranty and a limited lifetime warranty
Our verdict“Choose the Ivy for its elongated bowl, but confirm the flush rate and warranty details before placing an order.”
Swiss Madison Concorde One-Piece Toilet, Glossy White
The Swiss Madison Concorde stands apart from the Sublime II models with a square bowl, comfort-height design, and lower-volume 0.8/1.28 GPF dual flush. That combination suits buyers who want a more architectural look and an easier sitting height, rather than the compact, standard-height round profile of the Sublime II. Its fully skirted body and quick-release, soft-close seat also make exterior cleaning more straightforward. The tradeoff is that its square styling will not blend into every traditional bathroom, and its one-piece ceramic construction can be awkward to move into place. It is also not the choice for someone seeking the Ivy’s elongated shape. I’d put the Concorde ahead of the round models for height and design, but only if its distinctive bowl suits the room.
Pros:- Comfort-height bowl can make sitting down and standing up easier
- Dual flush offers 0.8 and 1.28 GPF options
- Fully skirted exterior is designed to simplify cleaning
- Soft-close, quick-release seat supports quieter use and easier seat removal
Cons:- Square bowl may not suit traditional bathroom styling
- One-piece construction can be difficult to move and install
- Square shape differs from the elongated seating profile of the Swiss Madison Ivy
Best for: Buyers seeking a comfort-height toilet with a distinctive square bowl, skirted styling, and lower-volume dual-flush options.
Not ideal for: Shoppers who prefer traditional rounded styling, need an elongated bowl, or want a lighter, easier-to-handle toilet.
- Model:SM-1T106
- Bowl shape:Square
- Flush options:0.8 GPF and 1.28 GPF
- Dimensions:26.05 × 14 × 29.25 inches (D × W × H)
- Material and finish:Ceramic, glossy white
- Seat material:Plastic
- Installation:Floor-mounted
- Warranty:1-year limited
Our verdict“Choose the Concorde if comfort height and square styling matter more to you than an elongated bowl or simpler handling.”
Casta Diva Elongated One-Piece Toilet with 17-Inch Comfort Height Seat
The Casta Diva is the non-Swiss Madison alternative here for buyers who put flush performance and a taller seat ahead of brand match. Its listing cites a MAP rating of 1000 for the siphon-jet flush, plus a 1.1/1.6 GPF dual-flush system; that gives it a stronger stated performance case than the Swiss Madison Concorde’s lower-volume flush figures, though the two use different specifications. The 17-inch comfort-height seat and elongated bowl also favor easier sitting and more seating room over the standard-height round Sublime II. Its skirted one-piece body is designed for easier cleaning, and the listing includes installation hardware. Tradeoffs include a one-year limited service warranty and a white-only finish in the supplied information. Buyers focused strictly on Swiss Madison models should choose among the other four instead.
Pros:- 17-inch comfort-height seat supports easier sitting and standing
- Elongated bowl provides more seating room than the round Sublime II
- Dual-flush system offers 1.1 and 1.6 GPF options
- Listing specifies a MAP rating of 1000 and includes installation hardware
Cons:- Not a Swiss Madison model, unlike the other four products in this group
- Only a white finish is specified
- Warranty information lists a 1-year limited term
Best for: Buyers open to another brand who want an elongated bowl, 17-inch comfort-height seat, and a published MAP flush rating.
Not ideal for: Shoppers committed to Swiss Madison, seeking multiple finish choices, or wanting warranty coverage beyond the listed one-year limited term.
- Model:CD-T005
- Rough-in:12 inches
- Flush options:1.1 GPF and 1.6 GPF
- Bowl shape:Elongated
- Seat height:17 inches
- Dimensions:27.17 × 14.37 × 25.39 inches (D × W × H)
- Material and installation:Ceramic; floor-mounted
- Certification:CUPC, EPA WaterSense
Our verdict“Consider the Casta Diva if a 17-inch seat and its stated flush rating outweigh your preference for a Swiss Madison toilet.”
Swiss Madison St. Tropez Comfort Height One-Piece Elongated Toilet
The St. Tropez Comfort Height pairs an elongated bowl with a dual-vortex flush, making it a sensible fit for buyers who value everyday comfort and a lower-volume flush option. Its 1.1 GPF setting uses less water per flush than the 1.6 GPF setting, while the higher-volume option gives buyers another choice. Compared with the Concorde square toilet, this model has a more familiar elongated shape and a standard 12-inch rough-in rather than a 10-inch one, so it suits a different bathroom layout and style. The tradeoff is its 109-pound weight, which can complicate handling during installation. Its one-year limited warranty is also a relatively short stated coverage period, so buyers should check the terms before purchase.
Pros:- Dual-vortex flush offers 1.1 and 1.6 GPF settings
- Elongated bowl provides more room than a round bowl
- Comfort-height design can suit buyers who prefer a higher seat
- Non-porous, scratch-resistant ceramic is designed for routine use
Cons:- At 109 pounds, it can be difficult for one person to handle during installation
- Requires a 12-inch rough-in, limiting fit in bathrooms with other layouts
- One-year limited warranty provides a defined but short coverage period
Best for: Buyers with a 12-inch rough-in who prefer an elongated bowl, a comfort-height design, and a choice of lower- or higher-volume flushing.
Not ideal for: People with a 10-inch or 14-inch rough-in, or DIY installers who need a lighter toilet to move and position.
- Model:SM-1T254
- Type:One-piece toilet
- Flush system:Dual-vortex dual flush
- Flush rate:1.1 / 1.6 GPF
- Rough-in:12 inches
- Bowl shape:Elongated
- Dimensions:27 x 15.12 x 31.18 inches (D x W x H)
- Weight:109 pounds
- Warranty:1-year limited warranty
Our verdict“Choose this St. Tropez if your bathroom has a 12-inch rough-in and comfort, an elongated bowl, and dual-flush options matter more than easy solo installation.”
Swiss Madison Concorde One-Piece Square Toilet, Dual Flush, 1.1/1.6 GPF, 10-Inch Rough-In
The Concorde is the lineup’s fit-specific choice: its 10-inch rough-in can serve bathrooms where a standard 12-inch toilet may not align with the existing plumbing. The square bowl and skirted trapway give it a more architectural look than the elongated St. Tropez Comfort Height, while the smooth-sided trapway is designed to make exterior cleaning less fussy. A soft-close, quick-release seat adds a practical convenience for households that want easier seat removal for cleaning. Its dual-flush settings match the St. Tropez’s 1.1/1.6 GPF choices, but the square bowl is a distinct comfort and style preference, not a universal upgrade. At 103 pounds, it remains a heavy floor-mounted unit, and buyers with a 12-inch rough-in should skip it rather than assume the plumbing can accommodate it.
Pros:- 10-inch rough-in suits bathrooms configured for that measurement
- Dual-flush settings offer 1.1 and 1.6 GPF options
- Skirted trapway presents a smooth exterior for easier cleaning
- Included seat has soft-close and quick-release functions
Cons:- The 10-inch rough-in limits compatibility with other bathroom layouts
- Square bowl may not suit buyers who prefer an elongated seat
- 103-pound weight can make positioning and installation difficult
Best for: Owners replacing a toilet in a bathroom with a confirmed 10-inch rough-in who want a square bowl, skirted sides, and a quick-release seat.
Not ideal for: Buyers with standard 12-inch or 14-inch rough-ins, or anyone who prefers the more familiar proportions of an elongated bowl.
- Model:SM-1T278
- Type:One-piece toilet
- Flush rates:1.1 / 1.6 GPF
- Rough-in:10 inches
- Bowl shape:Square
- Dimensions:27.15 x 14.75 x 29.15 inches (D x W x H)
- Weight:103 pounds
- Material:Ceramic
- Seat features:Soft-close and quick-release
Our verdict“Pick the Concorde when a 10-inch rough-in is the deciding constraint and its square profile suits your bathroom better than the elongated St. Tropez.”
Swiss Madison St. Tropez One-Piece Elongated Toilet, Glossy Black, Dual Flush
This glossy black St. Tropez is the lineup’s most visually distinct option, combining an elongated bowl with a skirted trapway and a dark finish that can anchor a contemporary bathroom. Its dual flush offers the same 1.1 or 1.6 GPF choice found on the St. Tropez Comfort Height, and both share an elongated profile; the black model instead emphasizes finish and a streamlined exterior. That look comes with a maintenance tradeoff: water spots and dust can stand out more against glossy black than glossy white. It also weighs 105 pounds, so installation may call for help. The listed standard-height seat range of 15–17 inches is another reason not to choose it solely for appearance if a comfort-height setup is a priority.
Pros:- Glossy black finish creates a distinctive alternative to the white St. Tropez
- Dual flush offers 1.1 and 1.6 GPF settings
- Elongated bowl provides more room than a round bowl

How We Picked
I compared the 13 listed toilets on the details that most affect a real purchase: rough-in compatibility, bowl shape, seat height, flush configuration, and finish. A toilet’s style matters, but it cannot compensate for a mismatch with existing plumbing or the available floor space. I also weighed one-piece construction and the range of configurations within each product family, since those affect the choice between a broadly adaptable model and a more specialized design.
The ranking favors models that serve a clear, common need while offering useful flexibility, which puts the 10-inch St. Tropez first and the compact round-bowl Sublime II among the strongest alternatives. Models with a specific advantage—such as a 14-inch rough-in, comfort height, square bowl, or dark finish—rank for those needs rather than as universal picks. I avoid treating finishes or flush labels as proof of performance: buyers should confirm the current specification sheet, included seat, and installation requirements before ordering.

Factors to Consider When Choosing Swissmadison Toilets
Before choosing among Swiss Madison toilets, I would narrow the options by installation constraints and household needs, then compare appearance. These broader checks can prevent common mismatches that product features alone do not resolve.
Measure the Rough-In Before Comparing Models
Rough-in is the distance from the finished wall to the center of the floor drain, not the distance to the baseboard or tank. Measure from the wall itself, allowing for the toilet’s existing position and any unusual trim. This roundup includes 10-, 12-, and 14-inch configurations, so choosing the wrong one can mean installation work or an unusable purchase. A nominal measurement may not account for wall finishes or an offset flange, so check the manufacturer’s fit diagram when your measurement falls close to a boundary. If plumbing changes are possible, compare their cost and disruption against choosing a model that matches the current setup. Do not assume two toilets from the same family share a rough-in just because their names are similar.
Choose Bowl Shape Around Clearance and Daily Use
An elongated bowl extends farther into the room but offers a shape many households prefer for everyday use. A round bowl, such as the Sublime II options, can preserve more floor clearance in a compact bathroom or powder room. Measure the distance from the wall behind the toilet to doors, drawers, and nearby fixtures before deciding that either shape will fit. A smaller footprint does not automatically mean easier installation; rough-in and side clearance still matter. When replacing an existing toilet, compare the old bowl’s projection with the new model’s dimensions rather than relying only on the bowl label. For shared bathrooms, weigh comfort against the space each person needs to move around the fixture.
Treat Seat Height as a Household Fit Decision
Comfort-height designs, including options in the Casta Diva and St. Tropez families, can make sitting down and standing up feel easier for many adults. A taller seat may be less comfortable for shorter users or children, so height is not a simple upgrade for every household. Check the specified height from the finished floor to the seat, since product descriptions may distinguish bowl height from seat height. Also verify whether the seat is included and whether its height changes the finished fit. If multiple people use the bathroom, consider who benefits most and whether a step stool or other accommodation is already part of the routine. Compare models by the installed seat height, not by a general comfort-height label alone.
Compare Flush Options Without Guessing at Performance
Dual-flush models offer different flush choices, which can help households avoid using a full flush for every use. The lineup includes dual-flush St. Tropez and Sublime II models, as well as a Concorde listing specified at 1.1/1.6 GPF. Those figures describe water use, not a guarantee of bowl-clearing performance or plumbing compatibility. Check the exact model documentation for flush controls, local requirements, and any installation limits before buying. A flush system with unfamiliar controls may take more explaining in a household shared with guests or children. I would compare the maintenance instructions and replacement-part availability alongside water-use claims, particularly when planning a long-term installation.
Decide Whether a Distinctive Finish Is Worth the Commitment
White is the easiest finish to coordinate with conventional fixtures and future bathroom changes. The lineup’s matte black, glossy black, and black-hardware options create different looks, but those details may be harder to match if other fixtures are replaced later. Finish names can also refer to different parts: a model with black hardware is not the same choice as an entirely black toilet. Ask whether the finish is consistent across the bowl, tank, and included components, and check care instructions before selecting a specialty surface. In a bathroom being remodeled as a coordinated set, a dark finish can be a deliberate design choice; for a single replacement, white usually leaves more options open. Avoid choosing solely from a product image, since lighting can change how a finish appears.
Check Installation Details and Future Service Needs
One-piece construction gives these models a unified appearance, but buyers still need to plan for delivery, handling, and access to the installation area. Confirm the toilet’s full dimensions, weight, mounting requirements, and the installer’s ability to work with the selected rough-in. Ask whether the package includes the seat, wax ring or other seal, bolts, and any flush components; included items can vary by listing. Before purchase, identify the manufacturer’s instructions and the parts that may need replacement over time. A less common finish or unusual configuration can narrow matching-part choices, so serviceability deserves a place in the decision. When installation complexity is uncertain, share the precise model number and fit diagram with a plumber before ordering.
Frequently Asked Questions
How do I choose between the 10-, 12-, and 14-inch rough-in Swiss Madison models?
Measure from the finished wall to the center of the floor drain, then compare that number with the exact model’s installation diagram. The St. Tropez options here include 10- and 14-inch versions, while the Sublime II list includes 10- and 12-inch versions. A model’s family name does not tell you its rough-in, so verify the full listing and model number. If the measurement is unusual or close to the stated size, ask a plumber whether the flange position allows the fit. Choosing by appearance before checking rough-in is the most avoidable source of a mismatch.
Is a round-bowl Sublime II a better choice than an elongated St. Tropez for a small bathroom?
The Sublime II’s round bowl is the more space-conscious direction, while an elongated St. Tropez extends farther into the room. Whether that difference matters depends on door swing, nearby cabinets, and the clearance available in front of the toilet. Compare the full projection dimensions for the exact models, since bowl shape alone does not establish the complete footprint. Also check rough-in: the listed Sublime II versions have different rough-in sizes, and one may not suit your plumbing. Choose the round bowl when clearance is the priority, not simply because the room is described as small.
Should I choose comfort height for every bathroom user?
No: a higher seat can make sitting and standing easier for many adults, but some shorter users and children may find it less comfortable. The Casta Diva and St. Tropez comfort-height options make sense when the people who use the bathroom most prefer a taller seat. Compare the installed seat height rather than relying on the product label, and check whether the seat comes with the toilet. In a shared bathroom, consider the full range of users and any existing accessibility needs. If possible, compare the specified height with a seat height that already feels comfortable at home.
Are the black Swiss Madison toilets a practical choice for a replacement?
They can be, but a dark toilet is a stronger design commitment than a white replacement. The lineup includes matte black, glossy black, and a St. Tropez version with black hardware, so confirm exactly which parts are dark before ordering. Check how the finish coordinates with the sink, bathtub, and other hardware, and review the maker’s cleaning guidance. White is usually easier to coordinate if surrounding fixtures may change later. For a planned bathroom design with matching components, black can be a deliberate fit; for a quick fixture replacement, it may limit future choices.
What should I verify before ordering a Swiss Madison one-piece toilet online?
Confirm the exact model number, rough-in, overall dimensions, bowl shape, and finished seat height against your bathroom and plumbing. Check what comes in the package, especially the seat and installation parts, rather than assuming every listing includes the same accessories. Review delivery access and handling needs because a one-piece toilet must be moved as a single unit. Ask your installer to check the mounting and flange requirements before the order is placed. Keeping the product documentation and parts information can also make later maintenance easier.
Conclusion
For the broadest fit among these choices, I recommend the St. Tropez elongated dual-flush with a 10-inch rough-in as best overall, provided that rough-in matches your bathroom. The Sublime II round is my pick for tighter floor plans, while a St. Tropez or Sublime II configuration matching your existing rough-in is the value-minded route because it can avoid plumbing changes; verify the exact specifications before buying. For a more elevated seating position, choose a Casta Diva comfort-height model, or compare it with the St. Tropez comfort-height option to find the preferred shape and fit. Beginners replacing a standard white toilet should start with a white model that matches the measured rough-in and has familiar dimensions, rather than a specialty finish or square bowl. For a specific design statement, the black St. Tropez models stand out; for a square-bowl look and specified dual-flush water use, consider the Concorde 10-inch model. My final rule is simple: choose for plumbing and household fit first, then settle on bowl shape and finish.
