Rated 4.4 out of 5 by 17 reviewers.
Rated 1.0 out of 5.0 by Filler is Junk Do not buy this toilet. While it flushes great, the filling mechanism is junk. When flushed the filler will frequently not start, and once filled it will frequently not stop filling. I also have a Kohler Cimmaron which works great, for less money. Save your money and buy the cheaper one. July 24, 2015
Rated 5.0 out of 5.0 by Beautiful and efficient Love the style of this toilet. Got the soft close lid which fits it perfectly. The tank did come with a 1 inch chip on it, but the tank lid hides it. Be sure to check over your toilet when you take delivery! So far the flush seems very strong. No need to flush twice even though it's only 1.28 gallons. March 13, 2014
Rated 5.0 out of 5.0 by Stylish and reliable I originally bought the one piece for > $500, but it cracked the first time I sat on it. I replaced it with the 2-piece and the savings helped pay for re-install. Also, this one is a bit taller than the one piece. December 19, 2013
Rated 5.0 out of 5.0 by nice design for toilet alcove this comfort height toilet replaced a leaky 20 year old one piece kohler toilet. this is a great design and the toilet tank fits well with the base unit in design. Flush seems great, quiet unit. Purchased the slow close lid. June 12, 2014
Rated 4.0 out of 5.0 by good qualty...went together verry easy I replaced a dual flush toilet with this one. The Kohler significantly out performed my old toilet. It's nice having to only flush once. June 24, 2014
Rated 5.0 out of 5.0 by Nice Piece of Furniture for the Bathroom Very nice - looks great - sits high and cleans easily. Great quiet and fast flush - absolutely happy and would recommend May 5, 2015
Rated 5.0 out of 5.0 by Nice Throne ! Comfort height is nice, flushes with authority. Noticeably less need to clean as the flushing action does what it is supposed to do. Have not needed to "double flush" as was needed with the toilet that was replaced. This toilet is highly recommended. Easy to install. Wax ring and mounting hardware ( 2 T bolts and nuts) were not included. Home Depot has these available. December 12, 2014
Rated 4.0 out of 5.0 by Good buy I really like the way it flushes. Saves a lot of water, and completely cleans out the bowl each time. Looks good too. August 5, 2014
