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.

Kohler K-3887 Reviews

Rated 5 out of 5 by from Excellent Fixture I purchased two of the Kohler Cimarron, round-bowl, 1.28GPF fixtures from Faucet Direct to replace two inefficient, 35 year old Briggs fixtures. I have been more than satisfied with this purchase, including ordering, price, shipment, installation, and the usage experience. The LTL freight was quicker and easier than UPS. Faucet Direct has been great from start to finish. The fixtures flush quickly and effectively every time. No double flushes are needed. They are quiet and quick from flush through refill. The round bowl self-cleans with no problem. Installation was an easy drop-in onto the existing flange. The base of the new fixture is slightly larger and more stable that the old fixture. A wax ring and a flexible water supply line must be separately acquired for installation. The flange bolts and caps are included with the fixture. One can pay a lot more for a high-efficiency toilet but I think you will not get a much better fixture than this one.

Rated 3 out of 5 by from Have a toilet brush handy... ...because it leaves solid waste on sides of the bowl. Although it doesn't get stopped up as my old American Standard did (I was always using a plunger), the water doesn't swirl around sufficiently to cleanse solid waste off the sides. You'll put the plunger away, only to have a collection of bowl brushes. I have the tall version of this bowl in ice grey. I recommend the 16.5 inch to all older people, as it makes a big difference. If it weren't for the lack of adequate self cleaning, this would be a perfect toilet.
