Rated 4.4 out of 5 by 151 reviewers.
Rated 5 out of 5 by Excellent toilet This is the second Kohler Cimarron toilet I've purchased from Home Depot because I was so pleased with the way the first one performed. It very rarely becomes plugged and the flushing action really does keep the bowl clean as advertised. I also really like it's efficient use of water. It seems to have a dual-mode flushing system, depending on how long you hold down the flushing handle, even though there is no information from Kohler that it is designed that way. May 29, 2012
Rated 5 out of 5 by Once I got it delivered in one piece it was great. It took four deliveries to get three undamaged pieces. Once installed it works great. Low flow flushes completely every time. September 6, 2014
Rated 3 out of 5 by not perfect The toilet is of good quality,however the flush was not always complete.It is over priced and identical to a lower priced toilet. The tank came broken, and had to be reordered. The second tank also came broken and was reordered.After considerable inconvenience,the toilet was finally installed. August 5, 2014
Rated 4 out of 5 by Easy to install. Flushes well Just installed this product. Easy to do. Tank flushing mechanism was already installed. You just add the rubber gasket and tighten the bolts. Flushes with less water than traditional toilets as advertised. Tank is pretty quiet when filling. One tip .... If you are going from a standard round bowl to elongated one, make sure your new bowl will sit on existing tiles. You may need to fill any gaps first. September 18, 2012
Rated 5 out of 5 by Very Good Toilet Best features are low water use and excellent flushing - I used to have to plunge my toilet once or twice a week. So far there has been no need to plunge the Cimarron! July 31, 2012
