Kohler K-3811 Reviews

Rated 2 out of 5 by from Kohler 3811 Toilet This 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.

Rated 5 out of 5 by from Kohler one piece toilet Santa Rosa 1.6 Kohler 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.
