Best Dual Flush Toilets of 2026

The Woodbridge T-0001 brings a high-end one-piece look to a mid-tier budget. Its fully skirted trapway hides the exposed piping found on traditional toilets, leaving a flat surface you can wipe in one pass. It is the value play for anyone who wants the smooth, modern silhouette without paying TOTO or Kohler money.

The siphonic flush creates a vacuum that pulls waste down, which keeps it quieter than a standard gravity-fed unit. The dual-flush buttons pair a roughly 1.0 GPF light flush with a 1.28 GPF full flush, so it earns its WaterSense certification on both settings rather than leaning on the light flush alone. Woodbridge rates it at a 1000 gram MaP score, so the full flush still clears heavy waste in one pass.

The HOROW T0338W is built for a contemporary bathroom where the toilet is meant to disappear into the design rather than announce itself. The one-piece body has no tank-to-bowl seam, so there is no grout-colored grime line to scrub, and the compact 26.6-inch depth tucks into a powder room without crowding the door swing.

It pairs that look with a dual flush rated at 1.1 GPF on the light setting and 1.6 GPF on the full setting, so it leans on the lighter button for its water savings rather than a sub-1.28 full flush. The ADA-friendly 17.3-inch seat height sits close to a dining chair, so getting up and down takes less effort than it does on a standard 15-inch bowl. A soft-close seat ships in the box. The trade-off is that it is a value-tier brand rather than a legacy name, so you are buying the design and the water numbers more than a decades-long service record.

The Swiss Madison St. Tropez is a favorite for interior designers working with modern spaces. It features a bold, fully skirted design with a slim tank that fits well in narrow bathrooms.

Beyond its looks, the dual-flush mechanism offers a 1.1 GPF light flush and a 1.6 GPF full flush, so the lighter button handles everyday liquid use while the full flush stays at the federal standard. It uses “Vortex” flush technology, which swirls water around the bowl to ensure full coverage. The quick-release seat is a nice feature, allowing you to pop the seat off instantly for deep cleaning.

The American Standard H2Option is a strong choice for households that struggle with frequent clogs. It utilizes a PowerWash rim that scrubs the bowl with pressurized water with every flush.

This two-piece model is highly efficient, using just 0.92 GPF for liquids and 1.28 GPF for solids. It features American Standard’s EverClean surface, a permanent glaze that inhibits the growth of stain and odor-causing bacteria. This keeps the mirror-like finish looking new with less scrubbing on your part.

The Gerber Maxwell Select earns the easiest-to-clean slot by removing the parts of a toilet that usually fight you with a brush. Its trapway is finished with a smooth glaze that keeps waste moving instead of clinging, so the bowl rinses cleaner on each flush and needs fewer hard scrubs to stay fresh.

It backs that up with a true dual flush rated at 1.0 GPF on the light setting and 1.28 GPF on the full setting, so it clears the WaterSense threshold on the full flush rather than leaning on the light button alone. A canister flush valve opens the full base of the tank to send water in fast, which helps clear the bowl in one pass and keeps clogs down. The Maxwell Select ships as a toilet-in-a-box: the tank, bowl, mounting hardware, wax ring, and a soft-close seat are all included, and the seat lifts off for cleaning the hinge area. It is a round-bowl unit at ADA chair height, so it suits a compact bathroom while still sitting tall enough to be easy to get on and off.

The Casta Diva takes the clog-prevention slot on the strength of its flush numbers rather than its badge. It is a skirted one-piece toilet with a fully-glazed, wide trapway and a siphon jet rated at a 1000 gram MaP score, the top of the waste-removal scale, so a single full flush clears heavy loads instead of leaving you reaching for the plunger.

It runs a true dual flush, 1.0 GPF on the light setting and 1.28 GPF on the full setting, so it keeps its WaterSense rating on the full flush rather than leaning on the light button alone ⁽²⁾. The one-piece shell has no tank-to-bowl seam to trap grime, and the 17.5 inch comfort-height elongated bowl sits close to a dining chair for easier sitting and standing. A soft-close, quick-release seat and the wax seal ship in the box. The trade-off is the same as the other value-tier picks here: you are buying the flush numbers and the easy-clean shell, not a legacy brand’s decades-long parts record.

The Convenient Height toilet lives up to its name with a rim height of 20 inches. This is significantly taller than standard 15-inch toilets and even exceeds most ADA-compliant “comfort height” models. It is specifically engineered to help seniors and those with mobility issues sit down and stand up safely.

Despite its unique height, it does not skimp on performance. It features a high-elevation gravity flush that uses 1.28 GPF for solids and 0.9 GPF for liquids. The structural reinforcement in the bowl allows it to support higher weight capacities than standard consumer toilets.
