Rated 4.5 out of 5 by 144 reviewers.
Rated 3.0 out of 5.0 by Tank arrived broken inside box, waiting for a replacement the unit seems good, so i don't blame Kohler, but the tank part arrived cracked from shipment. waiting on a replacement, no firm date given yet. they should probably ship in a double padded box. June 2, 2015
Rated 3.0 out of 5.0 by Not all it looks like - Read the fine print The toilet is fine, but read the fine print. It doesn't come with a toilet seat or waxie kit. A little frustrating, not the deal it looks like. January 13, 2015
Rated 5.0 out of 5.0 by Great Toilet - Misleading Online Description When I received the toilet from Home Depot the seat was missing. I call them and was told that it is not included (even though it is shown in the online picture). It cost me another 30 bucks. However, the toilet is great and was easy to install. The flush is quiet and completely cleans the bowl. I bought another Cimarron three years ago and the seat WAS included. I thought that one was great but this one is even better, it's quieter, and uses less water. October 28, 2014
Rated 5.0 out of 5.0 by Best Toilet Ever - and the Best Deal I now have 2 of these, replace over the last 4 months. My old toilets would plug practically every day. These new toilets have not plugged a single time, and flush with amazing power while only using 1.28 gallons per flush. You can hold the handle down for 2-3 seconds to get the maximum flush, but it is seldom, if ever necessary. I installed them both myself (just be careful not to over-tighten the bolts), using separately-purchased REINFORCED wax rings. Be sure to level/stabilize the toilet with shims and re-tighten the bolts after a few days or weeks (see the how-to video on this site). Seal to the floor with silicone sealer. Note that the biscuit color is lighter than almond. April 15, 2014
Rated 5.0 out of 5.0 by Flushed the old tolet away!! It took me about two hours to take the old one out put the new one in. It was very easy to do. Wish I would have done it years ago. You can see the saving with the first flush. No where near the water is being used. The two inches the toilet is raised made a big different on my comfort. July 26, 2014
Rated 5.0 out of 5.0 by Clean and Effective, Great product! I highly recommend this toilet, especially to anyone with stomach issues. I have been dealing with major stomach issues for the past two years and find it hard to keep the toilet clean. This toilet practically cleans itself! I love it!!! I installed two of these just over a month ago and have had no issues. They were easy to install, use low water, and are high quality. November 11, 2014
Rated 5.0 out of 5.0 by Just what I wanted I wanted to replace my contractor grade toilet which easily clogged with a quality toilet which flushes well. I ended up choosing the Kohler Cimarron Comfort Height 1.28 gpf. It is a 2 piece toilet. Bolting the tank to the toilet is much nicer now do to a bracket under the tank that holds the bolts. No more having to worry about them going down through the tank. When you flush it, it does not seem like it has a lot of power but in 3 months time, it has not once clogged or required a second flush. It does sit away from the wall pretty far but that is based on your rough-in. My only complaint is it does not come with a seat (but I new that before I purchased it). May 21, 2014
Rated 4.0 out of 5.0 by It Looks Good I like the size of this toilet. I also like the look. The seat did not come with it, so I ordered it. Initially, I had problems at the Home Depot store. When my contractor went to pick up the toilet, the tank was missing. I was so upset and disappointed because that stalled my move-in date. I lost money because I had to pay additional money to stay in another place until my toilet arrived. I was not impressed with how the managers handled the situation. I've only been using the toilet for about a month. So, I'm not sure if it will stand up to the test of time. One thing that I don't like about the toilet is that I can hear it filling up after I flushed it. I don't know if that is normal but I was under the assumption that I would not hear it filling up. However, the flush is powerful. May 14, 2015
