Kohler K-6428 Features:

  • One-piece configuration provides a uniform look and simplifies installation
  • Elongated bowl offers comfort and convenience, extending out an extra 1-1/2" compared to a round configuration
  • Covered under Kohler's 1 year limited warranty
  • Constructed of vitreous china
  • Comfort Height - designed for ease of use, with a higher than average bowl
  • WaterSense certified - toilet uses 20% less water than the current standard while still maintaining superior performance
  • Concealed trapway - a built in skirt hides the discharge passageway from view, for a smoother, less utilitarian appearance
  • Includes a soft close seat with grip-tight cover

Kohler K-6428 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.
  • 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.
