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.

Kohler K-3811 Reviews

Kohler 3811 ToiletThis has the "new" style flush. No flapper--it has a cylinder that raises up to let the water flush very rapidly. Mine leaked from reservoir from day one--about 2 gallons a day. Kohler sent a new seal, which didn't correct the problem. They are sending a whole new flush mechanism, but it is on backorder and will take a month. Not sure this better "mousetrap" of a flushing mechanism is good. The old style flappers have the weight of the water in the tank helping to make a good seal. These cylindars are light and don't have weight to make a good seal. I wouldn't recommend this one.

Kohler one piece toilet Santa Rosa 1.6Kohler is a great product, I was told that the inner makings on their most expensive models are exactly the same as the less expensive models. It looks and works great. The only negative is the sound it makes when it flushes is a bubbling, gurgling noise, quite loud and if your bath is off the bedroom, at night it will wake your spouse. I guess that is to be expected from all the 1.6 gal and less flushes. It is not as elongated as others but we wanted that due to space restraints.

Don't worry........great flush.I drove myself crazy reading reviews about how this toilet flushes! This is the 2nd Kohler Santa Rosa 1.6 I've installed in the last three months. Looks great in Ice Grey and no problems with performance.

Looks greatHard to get excited about a toilet, but this one looks great, the height is very comfortable. I wish I had gotten it last year before my hip replacement. I bought this model because of the larger flush (1.6 L). The one piece tank makes cleaning easier.

Not worth the moneyToilet doesn't clean with one flush. I've recently tried Kohler, American Standard and Jaccuzi and none of them flush as good as the old ones.
