Rated 4.6 out of 5 by 277 reviewers.
Rated 5.0 out of 5.0 by Great toilet The toilet itself is great. Flushes really well and does not use much water. The seat is not good (one came broken). However, I had planned to replace the seats with slow close seats and purchased the Bemis slow close elongated seat, opting for the heavier enamel on wood which was only an extra dollar at $35.98 (not listed on the web but available in the store at Seaside, CA). BTW, the Vigo vessel sink and faucet and the Home Decorators Fuji 24 inch vanity were also purchased from Home depot. These were all excellent purchases. January 13, 2015
Rated 4.0 out of 5.0 by Looks great; easy to install, but one thing to consider Looks great, was easy to install, functions well for low flow, good value, a quality product. One technical diappointment. When selecting this toilet the specs led me to believe it would extend from the wall about an inch less than my current toilet. This was an issue due to a our plans for a new shower door. But once installed it actually extended almost an inch further from the wall. Rough-in was 12 inches for both old and new. This was a big disappointment and resulted in a shower door of 24" rather than the planned 26" which would have worked better. Other than that technical detail, we love the toilet. July 11, 2014
Rated 5.0 out of 5.0 by Happy we bought this toilet! This toilet was purchased for my mothers bathroom. She is 80 years old and she loves the new toilet. She likes it because it is compact, one piece, and has a nice finish that is easy to clean. It is slightly higher and easier for her to use. Good purchase, I would recommend it. December 26, 2014
Rated 4.0 out of 5.0 by Great toliet I have three of these toilets in my house they are very easy to install and easy to clean being a one-piece. One of the toilets I have had for almost three years with no problems and the others have been installed for two years and one for about a month. The only thing i do not like is the seat which is cheap plastic and I will eventually change the seats out this is why I am giving 4 stars instead of 5. August 19, 2014
Rated 5.0 out of 5.0 by This toilet is a great addition to a small bathroom. This toilet is a great replacement/addition to our very small bathroom. It is very stylish and really fits well into the small space. Flushes efficiently and quietly, very clean look in our contemporary home. Comfortable throne height! Very satisfied user April 30, 2014
Rated 4.0 out of 5.0 by Good product, nice compact size for an elongated seat design We changed out an older Kohler Lite round bowl standard size toilet that worked fine but we wanted the comfort height design as we have one of those at our vacation home. The nice thing about this product is that it is a one piece design and sticks out no more than the one we replaced. Using only 1.2 gallons to flush it does the job, but its not like one of those turbo flush units but it has worked well so far. At 100lbs. you will need a helper to set it but that's no too bad for two guys, or girls to set. December 23, 2014
Rated 5.0 out of 5.0 by Santa Rosa is a five star for style....... This toilet was easy to install being a one piece toilet. The flush is very fast and powerful. The seat mounting hinges are not very good, If you don't hold the( horse shoe shaped slot) while tightening the screw or tighten to tight-the seat will not stay put. Kohler's toilet quality is outstanding. Very heavy-yes August 27, 2014
Rated 2.0 out of 5.0 by Quality lacking I have relied on Kohler in the past but the quality has "tanked". We have had the toilet less than a year and the flush handle lever that is inside the tank is encrusted with rust. The metal lever is cheap and will not survive a wet environment. June 22, 2015
