Product Technologies / Benefits:

  • Class Five: The Class Five siphon jet flushing system is designed for high-powered bulk flushing performance. Water flow is maximized with a larger than standard flush valve, which allows rapid release of water, and direct fed jets that quickly clear the bowl.
  • 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.
