Rated 4.6 out of 5 by 299 reviewers.
Rated 5.0 out of 5.0 by The perfect toilet! Although not a very glamorous subject, I have to say that this is a wonderful product! It is incredibly quiet and water- efficient. The flush is instantaneous and the tank fills in under 10 seconds (no waiting around to make sure the water shuts off). The glossy black finish is very attractive. This toilet is slightly taller than our other toilets, and this makes it much easier for my mother, who has arthritis in her hip, to use. It was also very reasonably priced. All in all, a superior product. We are very pleased. December 10, 2013
Rated 5.0 out of 5.0 by Black is bad idea, pick grey or something lighter as a previous owner of a black toilet, it shows everything. You never realize how much WHITE hard water stains are on a toilet, untill you have a black one. This toilet comes in many color options though December 3, 2012
Rated 4.0 out of 5.0 by Good Value Good Value . But came without a wax ring and the bolts whitch tha same white one I purchased from the store came with. Also the seat is less quality than the one that came with the white one I got from the store . August 6, 2013
Rated 5.0 out of 5.0 by I love the comfort height and energy efficicency The black color really makes it stand out. It looks great August 13, 2013
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 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 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 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
