Product Technologies / Benefits:

  • Touchless: Kohler Touchless toilets are the ideal no-touch flush solution - no handle means no germs either picked up or left behind. The touchless module projects an electromagnetic field through the lid of the tank, which activates the flush when a hand is placed above.
  • AquaPiston: AquaPiston canisters allow water to flow into the bowl from all sides, increasing a flushing system's power and efficiency.
  • 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.
