For a comfort-height bowl, choose the Swiss Madison St. Tropez SM-1T254; for standard height, the Sublime SM-1T205 or the rounded Monaco SM-1T108. All three are skirted one-pieces with a soft-close seat and a 12-inch rough-in, and Swiss Madison lists a 1.1 / 1.6 gpf dual flush, so confirm the flush rating if your area requires 1.28 gpf.

| St. Tropez SM-1T254 | Comfort height, 17 to 19 in. | Dual Vortex, 1.1 / 1.6 gpf |

Swiss Madison sells modern one-piece toilets with fully skirted sides, which are easy to wipe clean. Swiss Madison lists for all three a standard 12-inch rough-in, an elongated bowl, a fully glazed and skirted trapway, 3-inch access holes for installation, and a soft-close, quick-release seat. The main differences are height, flush style and shape.
Important: check the flush rate
On our October 15, 2026 check, Amazon listing titles for the Sublime and Monaco described a 0.8 / 1.28 gpf dual flush, while Swiss Madison’s own product pages (swissmadison.com) list 1.1 / 1.6 gpf for the same model numbers. We use the maker’s figures here. Dual-flush toilets are rated using an effective flush volume that averages the light and full flushes, and some states and cities require high-efficiency or WaterSense-certified toilets in new installs. If that applies where you live, confirm the exact rating and certification with Swiss Madison or the seller before you buy.

Comfort height or standard height?
Swiss Madison lists the St. Tropez at 17 to 19 inches and the Sublime and Monaco at 15 to 17 inches. A taller bowl makes sitting and standing easier for many adults; a standard-height bowl can be easier for children and shorter adults. Our chair-height toilet guide covers heights and ADA notes.
Skirted one-piece toilets: the trade-offs
A skirted toilet hides the trapway behind smooth sides, so there are no curves to scrub. The catch is installation: skirted toilets usually fasten through access holes in the sides or use special brackets, so read the instructions before you start. Swiss Madison lists 3-inch access holes on these models. One-piece toilets are also heavier to lift than the bowl of a two-piece. Our skirted toilet guide and one-piece vs two-piece guide cover these trade-offs.
Rough-in and space
All three are listed for a standard 12-inch rough-in, measured from the finished wall to the center of the closet bolts. If yours is 10 or 14 inches, Swiss Madison sells other St. Tropez models for those rough-ins; buy the version that matches. Our rough-in guide explains measuring. For a very small bathroom, our compact toilet guide covers shorter bowls.
Dual flush buttons
The Sublime and Monaco use dual-flush buttons that, per Swiss Madison, let you choose a 1.1-gallon light flush or a 1.6-gallon full flush. Use the light flush for liquid waste and the full flush for solids. Buttons on top of the tank lid mean the lid must sit properly on the button mechanism, so set it down carefully after any repair inside the tank.
Quick-release seat
Swiss Madison lists a soft-close, quick-release seat on all three toilets. Soft close lowers the seat and lid gently instead of letting them slam. Quick release means the seat lifts off with the push of a button, so you can clean the hinge area and the top of the bowl, which is where grime builds up on most toilets. Swiss Madison sells replacement seats for its toilets by model if one breaks.
Colors and hardware
Swiss Madison offers several of these toilets in more than one color, such as bisque and matte black versions on Amazon, and sells color-matched or contrasting toilet hardware, including brushed gold and black hardware for the Sublime. The St. Tropez linked here has white color-matched hardware. If you want a specific color, check that the model number on the listing matches the color you want before ordering.
Installing a one-piece toilet
Set a new wax ring on the flange, lower the toilet straight down onto the bolts, and tighten the nuts evenly and only until snug, since vitreous china can crack. On a skirted model, follow the maker’s instructions for the side fasteners through the access holes. Connect the supply line, open the valve, and flush several times while checking the base and supply for leaks. Our wax ring guide and supply line guide cover those parts.
