Santa Rosa

Santa Rosa Comfort Height 1 piece compact elongated 1.6 gpf toilet offers the exceptional functionality you expect from Kohler in a smaller footprint, so you can transform even the smallest of bathrooms into a well-designed, comfortable space. 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
  • 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.

Product Specifications:

  • Overall Height: 28-3/16" (measured from bottom of base to top of tank)
  • Overall Depth: 27-3/4" (measured from back of tank to front of rim)
  • Overall Width: 18-3/4" (measured from rightmost to leftmost edge of toilet)
  • Bowl Height: 16-1/2" (measured from floor to bowl rim)
  • Flow Rate: 1.6 GPF (gallons per flush)
  • Water Area: 11" x 8-1/8" (inner rim dimensions of bowl, length x width)
  • Water Depth (from Rim): 6-1/4"
  • Tank Width: 18-3/4" (measured from leftmost to rightmost edge of tank)
  • Tank Depth: 6-9/16" (measured from back edge to front edge of tank)
  • Trapway (Discharge Passageway) Size: 2-1/8"
  • Distance Between Toilet Seat Installation Holes: 5-1/2"
