Swiss Madison St. Tropez One-Piece Toilet Review: Budget-Friendly Dual Flush with a MaP Score of 600g

The Swiss Madison St. Tropez sells on a simple promise, a modern skirted one-piece look and dual-flush water savings at a budget price. We compared its manufacturer specifications, flush design and owner feedback against the toilets buyers usually cross-shop, and a clear picture emerges. This is a style-forward, water-thrifty fixture that clears the bowl with a mid-pack MaP score rather than a class-leading one. Below we break down the flush system, the water use, the build and cleaning details, how it stacks up against premium rivals, and exactly who should buy it.

What the St. Tropez is built to do

The St. Tropez is a one-piece, elongated, floor-mount toilet made from glazed ceramic. Swiss Madison sells it as a seamless skirted design, meaning the trapway is hidden behind a smooth outer shell with no exposed curves or crevices to trap grime. That single-body construction and skirted profile are the main reasons buyers choose it, since the look normally costs more from legacy brands. Configurations are offered in standard height and a taller comfort-height version, and in a wide palette that includes glossy and matte finishes in white, black, gray and bisque. A soft-close, quick-release seat is included, and it detaches with a button for easier cleaning.

Swiss Madison is a value-focused brand that competes on style and price rather than on the deep parts networks of the old American makers. If you want the wider lineup context and how the St. Tropez sits among the brand's other models, our Swiss Madison brand guide maps the range. Knowing the brand matters here, because parts and long-term support differ from what you get with a mainstream American Standard or Kohler fixture.

Flush performance: Vortex dual flush and the MaP 600 score

The St. Tropez uses Swiss Madison's Vortex flushing system, a rimless-style design that sends water through dual nozzles to spin a vortex around the bowl instead of relying on a ring of small rim holes. The claimed benefit is a more complete wash of the bowl surface on each flush, with fewer holes to clog or scale over time. On paper that is a sound approach, and owners generally report a clean bowl wall after flushing.

Clearing power is where honest expectations matter. Manufacturer and retailer data list a MaP score of 600 grams at the full 1.28 gallon flush. The Maximum Performance test records how many grams of solid waste a toilet removes in a single flush, and the scale tops out at 1000 grams. A 600 gram result means the St. Tropez clears roughly 1.3 pounds of solid waste per flush. That is comfortably above what a typical household actually produces in one sitting, but it sits below the 1000 gram ceiling that premium TOTO and Kohler models reach. If you want a full explanation of the number and why it beats vague marketing adjectives, read our guide on what a MaP score is before you shop.

The practical takeaway is that the St. Tropez is a capable everyday flusher, not a heavy-duty clearing champion. For most bathrooms it will handle daily use without drama, and the dual nozzles help keep the bowl clean. Households with very heavy demands, or anyone who has fought recurring clogs, will get more margin from a MaP 1000 model.

Water use and the dual-flush tradeoff

Dual flush is the St. Tropez headline feature. A short press releases 0.8 gallons for liquid waste, and a full press uses 1.28 gallons for solids. The 0.8 gallon reduced flush is unusually low, undercutting many rivals whose light flush lands near 1.0 gallon, so a household that uses the reduced flush often can trim meaningful water over a year. The full 1.28 gallon flush meets the federal 1.6 gallon standard with room to spare and qualifies under the WaterSense efficiency threshold of 1.28 gallons or less.

The tradeoff attached to any dual-flush design is the button mechanism itself. Top-mounted push buttons and their cartridges are a more complex point of failure than a single trip lever, and Swiss Madison's parts availability is thinner than the major brands. Buyers weighing flush volumes across the market can see how the full flush stacks up in our comparison of 1.28 GPF versus 1.6 GPF, which explains why 1.28 has become the efficient default without sacrificing clearing on well-designed bowls.

Design, build and cleaning

The one-piece body is the St. Tropez calling card. With no seam between tank and bowl, there is no gasket joint to leak and no crevice to collect dust, which makes the exterior faster to wipe down. The skirted trapway continues that theme by presenting a flat side wall instead of the scalloped underbelly of a standard two-piece. Owners consistently praise the modern look and the easy-clean exterior, and the included soft-close seat closes quietly and lifts off for cleaning behind the hinges.

The bowl is glazed ceramic that Swiss Madison describes as scratch-resistant and non-porous, a standard surface that resists staining but does not carry the branded antimicrobial glazes some premium lines advertise. The rimless Vortex bowl helps here too, since there is no hidden rim channel where mineral scale and bacteria usually build up. Installation uses a standard 12-inch rough-in, matching the drain spacing in most homes. One honest caution from owner feedback is weight and handling, one-piece toilets are heavy and awkward to set solo, so plan for a helper. Swiss Madison backs the toilet with a limited warranty that owners extend by registering the product, shorter and less established than the lifetime chinaware coverage from the big American brands.

How the St. Tropez compares

Against the toilets people cross-shop, the St. Tropez wins on price and on a lower reduced flush, but gives up ground on clearing power and long-term support. The obvious dual-flush rival is the TOTO Aquia IV, which pairs a 1.28 gallon full flush and a 0.9 gallon reduced flush with a full MaP 1000 rating. Single-flush heavyweights like the TOTO Drake II and the Kohler Highline also reach MaP 1000. The St. Tropez counters with a lower 0.8 gallon light flush and a skirted one-piece look at a budget price, so the decision comes down to whether you value maximum clearing and brand support or style and water savings for less.

If your priority is the strongest possible clearing in a dual-flush body, the TOTO Aquia IV is the direct upgrade. If you want a single powerful flush and a deep parts network, the TOTO Drake II or Kohler Highline are the safe long-term picks. If you want a modern skirted one-piece with a very low reduced flush and a friendly price, the St. Tropez earns its place. You can see how each lands in our roundup of the best flushing toilets.

Pros and cons

• Pro: Modern skirted one-piece design with no tank-to-bowl seam and an easy-wipe exterior.
• Pro: Very low 0.8 gallon reduced flush, undercutting many dual-flush rivals on water use.
• Pro: Rimless-style Vortex bowl with dual nozzles reduces the hidden rim channel where scale builds.
• Pro: WaterSense efficient at the 1.28 gallon full flush, with a soft-close seat included.
• Con: MaP 600 clearing sits below the MaP 1000 ceiling that premium TOTO and Kohler models reach.
• Con: Dual-flush push-button cartridges add a failure point, and Swiss Madison parts are less widely stocked.
• Con: Shorter, registration-based warranty than the lifetime chinaware coverage from legacy American brands.

Who should buy the St. Tropez

The St. Tropez fits style-conscious, budget-minded buyers who want a modern skirted one-piece look and strong water savings without paying premium-brand prices. It is a smart pick for guest bathrooms, updated powder rooms and low-to-moderate traffic homes where daily reliability and a clean design matter more than maximum clearing headroom. The comfort-height version suits taller users or anyone who prefers a higher seat. Buyers with very heavy household demand, a history of stubborn clogs, or a strong preference for a lifetime warranty and easy nationwide parts should choose a MaP 1000 model like the TOTO Aquia IV or Drake II instead.
