Trusted for years by professionals and homeowners, Cimarron features KOHLER's most complete flush ever, Revolution 360 degree swirl flush powered by the AquaPiston flush valve. Revolution 360 degree swirl flushing technology keeps your bowl cleaner longer than a conventional flush. Installation saves you time and money, too, with KOHLER's patent-pending two-bolt tank-to-bowl omni-directional leveling system.

                  I have bought this full package. But the towel seat lid does not seem to line up to the edge of the toilet bowl. Is the toilet seat lid is designed to be shorter than the bowl or should it align perfectly?

                    The reason for only 4 stars, I installed the toilet after installing, turned water on , I had a leak from back of tank , after a couple of times re installing I took main drain in the tank out and saw it was miss aligned from factory,pinching seal re seated it now all is well. Nice toilet, looks good, nice flush.

                    Helpful part — don’t throw the original away like I did
                    This is the small plastic piece that sits between the Kohler toilet seat hinges. I accidentally threw the original one away, not realizing how important it is, and my toilet seat kept coming loose as a result. After installing this replacement, the seat is solid again and works exactly like it should. Fit was perfect for my Kohler toilet. Just a heads-up for anyone installing or cleaning their toilet seat: don’t throw this part away. If you already did, this replacement does the job and saves you from replacing the entire seat.

                      Got One In An Emergency; Now Buying Another One
                      I got this 1.5 years ago in an emergency, when I had an old upstairs toilet that was cracked and leaking at the base (all the way down to the first floor). I did not have a lot of time to do any research and I was facing a substantial home repair bill. So I logged on and I picked one that was in stock, looked decent, and cost less than $300. Hands down it is the best toilet I've ever owned. I love the seat height, flush power, rapid refilling and soft-close lid. The tall form factor and glossy white finish make the "throne" quite attractive on my black tile floor. Zero complaints so far, and indeed I am so happy with this toilet's performance that I am buying another for the 2nd bath early next year. Still less than $300!

                        If anyone says this is a great toilet...
                        ...they are full of what a toilet is used for. A toilet, totally unused for 10 days, resulted in a gray bowl under the water. This is also a horribly poor flushing toilet as it doesn't have enough water with enough force to flush the entire bowl resulting in double or triple flushes. How is that saving water? The pic attached is a toilet that did not flush its contents and was inadvertently left for 2 days. Disgusting!

                        Hello Kell, this is Lisa with Kohler Co. I am sorry to hear of your experience with your Cimarron® toilet. We are more than glad to help. There are often minor adjustments that can be made in your toilet tank to ensure it flushes and cleans the bowl properly. You will want to ensure the chain that comes off the canister flush valve is taut. There should be no slack in the chain (1-2 links at most). The black refill tube in the toilet should be connected on both ends; from the fill valve to the top of the canister flush valve. The water level in the tank should also be to the waterline marking listed on the canister flush valve. If you do need further assistance, please feel free to contact us at KohlerCustServ@Kohler.com. We look forward to hearing from you. Sincerely, Lisa A., Kohler Customer Service

                          The toilet came well packaged and easy instructions to follow. Once I unpackaged all of the parts, I followed the instructions in sequence. First, the bowl on the was ring, then the tank to the bowl, then the water supply to the tank. Upon turning on the supply, there were no leaks at the tank and the first flush went down uneventfully. The toilet has been in service for about a month, and has worked as advertised. There have been no issues in this excellent product.

                          Porcelain is poor quality.
                          Mechanicals are great. Flushes and fills fibers. The problem is the porcelain. It’s garbage. Even though my water in San Diego is from 7 to 8 ph with no iron this toilet leaves streaks where the water flows down the sides. I have a 20+ year old American Standard that is spotless. The stain won’t come out. It looks terrible
