The elongated seat and chair-like height ensure comfortable use.

Rated 4.1 out of 5 by 18 reviewers.
Rated 5.0 out of 5.0 by Totally Satisfied This toilet replaced an eljer that clogged up about once per week. The eljer was a beautiful looking toilet but it was too much trouble. This toilet has NEVER clogged in almost a year. It looks nice and I am now thinking of getting another one for a different bathroom. May 16, 2014
Rated 2.0 out of 5.0 by Had to return it The seat fit and color matched the toilet perfectly, unfortunately, there were bubbles in the finish...so it's going back for a replacement. February 11, 2014
Rated 3.0 out of 5.0 by Nice toilet, read the fine print So sorry I did not read the fine print to see that the toilet seat was not included. Great shipment to house but it was missing the wax ring and multiple nuts and bolts. This involved and extra hour pay for the installer as I ran back and forth for supplies. I am very disappointed. Had I checked for all parts I would still not have noticed as this is not something I normally do. I have purchase 2 other Kohler toilets in the past 2 years, both included toilet seats. The picture shows a toilet seat too. October 4, 2014
Rated 4.0 out of 5.0 by Highline toilet Clearly a quality toilet.Easy to install.Almost Flushes everything.But for the most part does an excellent job.Happy I bought it. January 13, 2015
Rated 2.0 out of 5.0 by Incomplete flush Does not flush bowl contents entiely (#2). Very disappointing for such an otherwise quality toilet. Simply does not perform. Very embarrasing if you have company, for them and for you. November 5, 2014
