This WaterSense-labeled high-efficiency toilet combines water conservation with the versatile style of the Cimarron collection. A 1.28-gallon flush provides significant water savings of up to 16,500 gallons per year, compared to a 3.5-Gal toilet, without sacrificing performance. This toilet features innovative AquaPiston technology, a patented flush engine, that delivers a fast, powerful, and plug-free flush. An elongated bowl, positioned at the height of a standard chair, offers comfort and ease of use.

  • AquaPiston canister allows water to flow into the bowl from all sides (360°), increasing the power and effectiveness of the flush
  • Flush valve's 3: 2 ratio harnesses the natural force of gravity and optimizes flush performance
  • Durable canister design has 90% less exposed seal material than a 3 in. flapper, for leak-free performance
  • Light-touch canister flush requires a lower actuation force than a flapper
  • AquaPiston canister flush valve optimizes flush performance and resists warping and deterioration
  • Standard 12 in. rough-in.

Rated 4.4 out of 5 by 153 reviewers.
Rated 5.0 out of 5.0 by AWESOME Easy to install, "NO" leaking from tank-to-bowl connection due to the innovative connection design. (Respectfully)-This toilet will flush large stool loads completely with no second flushing required. If you plug this toilet than you must be using way to much toilet paper.I originally purchased another brand made toilet, and had to replace it due to a leaking tank/bowl connection. This Kohler toilet will flush as well as the other brand, which is reported to be a better flushing unit. The 16.5" bowl height of this toilet has really improved the comfort level for doing the deed. Overall-- an EXCELLENT product. June 24, 2012

Rated 5.0 out of 5.0 by Super simple installation even with working with an old house Product arrived on time and in good condition. Installation was a breeze. Might have been nice for someone to mention the seat was not included but maybe I missed it. May 1, 2012
Rated 5.0 out of 5.0 by Great quality Love the appearance May 4, 2011
Rated 3.0 out of 5.0 No toilet seat included!!! Nice toilet but it wasn’t cheap and got a whole lot more expensive when I had to purchase a seat for it. In fine print it stated that a seat wasn’t included. Why not??? For the price paid it should have auto flush. I will never purchase another toilet or anything from Home Depot online. I will not purchase another anything from Koehler. Come on $500 plus tax and no toilet seat?? September 6, 2011
