Rated 4.4 out of 5 by 192 reviewers.
Rated 5.0 out of 5.0 by Comfort Height Toilet I picked up the two boxes at the store. The products were well packed, but the lid had a chunk missing on the underside which is used for centering the lid on the tank, and not visible. I used epoxy to reattach the piece, rather than going through the hassle of getting a replacement. This is my second Cimarron, Comfort Height, 1.6 gallon I have purchased. The first one I bought in 2013 upon inspection, had casting spurs in the main flow channel which would have snagged paper. I filed them off and all is well. This Cimarron was all smooth and had no casting flaws. Did notice this 2015 Aquapiston base sits a bit higher in the tank, and flushes slightly less water, but still flushes very well. Can't beat the comfort height, as you get older. Came with everything for installation except the wax ring, and self closing seat, but I knew this from before. Just follow the instructions!

Rated 5.0 out of 5.0 by My second Cimarron Bought the exact same one, from the exact same place ( (but at a quite a bit higher price) several months ago. So, the decision this time was automatic. Flushes greart, clean rinses. Only complaint: The small hook that attaches to the flush lever's chain keeps getting disconnected; hard to crimp it right. May 2, 2011
Rated 5.0 out of 5.0 by Height is perfect! So far flush is wonderful. Price not too bad. flush is quiet & easy. Height perfect for me. Seat is comfortable & pretty. December 10, 2013
Rated 5.0 out of 5.0 by Great product,excellent function I am totally pleased with my purchase of two Kohler toilets. They use less water but the flush quality is high. I bought the slightly taller model which is better for taller people but my 4 year old Grandson doesn't have a problem using them. Very pleased with the quality of this product. December 27, 2011
Rated 5.0 out of 5.0 by Exceeded my expectations so far I was concerned updating from my old 3.5 gal with now required 1.6 Did my research including reviews from several sources HD included. Decided on this Kohler and I am surprised at how good it works. Still not used to what I would kind of describe as almost a mini flush but absolutely has handled all thrown at it! The added height was a concern and is noted by my wife who is in 5-2 5-3 range. She is fine with it but might prefer standard height if had been familiar. I being 6-2 it was of no note except as positive for when you get older then easier to get up. Elongated is good if have room, had round it was fine. I plan to replace two other toilets with Cimarron, those one I can get away with white ( bisque is nice and was needed but over $100 more for color annoying ) both will be normal height and round based on room size etc. Some had commented on side cleaning action being not so good, have not found that to be the case at all.

Rated 4.0 out of 5.0 by Old school skeptic rather impressed! As an old school skeptic, I was really disappointed that I was being forced by the liberal tree huggers into buying a "green toilet" with only a 1.6 gallon flush. The Cimarron does a great job getting "the load" down, but I will admit that more often than not "marks" are left behind. So, I still end up flushing twice and using 3.2 gallons. For these occasions I still miss my flush-once 3.0 gallon toilets but the Cimarron is a pretty good toilet. Hope this helps someone while putting a smile on your face! August 24, 2011
Rated 3.0 out of 5.0 IMPERFECTIONS IN WORKMANSHIP product was received with imperfections in workmanship very disappointed. waiting at least 3 weeks now for Kohler to replace tank cover which was DIMPLED IN CERAMIC March 18, 2014
Rated 4.0 out of 5.0 by Great toilet. We didn't realize that this toilet does not come with a toilet seat. So, be sure to order one with your purchase. August 13, 2014
