Santa Rosa

Santa Rosa toilet's one-piece design adds a contemporary look to your bathroom environment while conserving space with a compact elongated bowl. Its 1.28-gallon high-efficiency flush provides significant water savings of up to 16,500 gallons per year, versus an old 3.5-gallon toilet, without sacrificing performance. A chair-height, elongated seat makes it comfortable to use.Lifestyle

 

Product 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
  • The Santa Rosa toilet offers exceptional functionality with a small footprint
  • Constructed of durable, easy to clean vitreous china
  • Installs in a floor mounted configuration
  • Features a powerful gravity flush with AquaPiston technology
  • ADA compliant - complies with the standards for toilets set forth by the Americans with Disabilities Act
  • 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
  • Includes Brevia Quiet-Close with Grip-Tight Seat

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.
  • 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.
