Product Technologies / Benefits:

Easy to Clean: One-piece toilets integrate the tank and bowl into a seamless easy-to-clean design. Because the toilet's shape has fewer crevasses than two-piece models, there are not as many spaces for dirt to hide. This model also features a fully skirted trapway, meaning that the sides of the toilet are smooth and flat. This feature simplifies cleaning and offers a look that is aesthetically pleasing as well.
Simplified Installation: The Tresham one-piece toilet features an innovative trapway installation system. The system anchors the toilet to the floor for a secure, caulk-free installation. The standard 12" rough-in requires no drilling, no special tools and is easy to install on all floor types. There are also kits available to accommodate 10 and 14 inch rough-in installations.
AquaPiston: AquaPiston single flush canister technology uses the force of gravity and a precision-engineered tank, bowl, and trapway to create a strong, efficient siphon during flushing. The canister flush valve's 3:2 ratio optimizes flush performance and resists warping and deterioration, while its durable design features 90% less exposed seal material than a standard 3-inch flapper flush valve, guaranteeing leak-free performance. The light-touch canister requires lower activation force than a flapper, and once activated, allows water to flow into the bowl from all sides (360 degrees), increasing each flush's power and effectiveness.
Comfort Height: Comfort Height toilets offer the greatest accessibility and ease of use with a bowl height of between 16-1/2" and 18", the same as a standard chair.
WaterSense Certified Product: To help make a difference on a global scale and to further its role as an industry leader in eco-performance practices, Kohler has established partnerships with a number of environmental organizations, including WaterSense. Many Kohler faucets and toilets are equipped with low-flow technology - they use less water, while continuing to meet superior performance standards.
