Kohler Technologies / Benefits:

  • 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.
  • Revolution 360™: Revolution 360™ swirl flushing technology generates a forceful swirling motion to keep the bowl cleaner, longer.
  • 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.
  • ReadyLock™ Patented ReadyLock™™ installation system is a simple solution for skirted toilets that saves time, hassle, and eliminates the need to drill into the floor for a standard 12-inch rough-in
  • 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.
