Product Overview
Product Features:
- Tank only configuration - allows the opportunity to match pieces with a selected bowl
- Covered under Kohler's 1 year limited warranty
- Constructed of vitreous china for a clean and modern look
- Insulated tank - prevents condensation from forming on the outside of the toilet tank and ending up on the floor
- WaterSense certified - toilet uses 20% less water than the current standard while still maintaining superior performance
Product 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.
- Insuliner: An Insuliner tank liner reduces condensation on the outside of the toilet tank, ideal for high-humidity locations.
- 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 are equipped with low-flow technology - they use less water, while continuing to meet superior performance standards.
