Same recurring problem
I bought 3 Koehler toilets in the past 3 years for each of our bathrooms. I have 2 of these and the same problem with the handle sticking in the down position and the flushing mechanism staying in the upright position causing the toilet to continuously run. It’s very annoying when we have people over and have tried everything to fix. When they work properly it’s a decent toilet.

Dave, we are sorry to hear of the issue you are experiencing with your Cimarron toilet. We first recommend checking the nut on the trip lever to ensure it is not too tight. Next, you can check the chain to verify it is taut when the toilet is resting. If this does not resolve the issue, please contact our Customer Service team at 1-800-4Kohler (1-800-456-4537). We are here to help. - Jessica P. Kohler Customer Service.

    Nice Comfort height toilet and fits nicely in a small bathroom. Does not come with a toilet seat so I added a nice Bemis round seat that fits great. This is our first toilet that has the AquaPiston Flush Technology. I kind of expected it to be like the "old school" toilet found in the public schools. You know, those flush valve toilets where you could flush a behemoth jobby down with those badboys...and when you flush then they sound like a 747 taking off...would echo down the hallways : ) but no, it doesn't even come close to that. Hopefully it will not get plugged up but if it does, I am wondering if a round toilet plunger would work on the odd shaped hole.... ??? Still I do think this is a very nice toilet and I enjoy the Comfort Height.

      We got this 1.6 GPF toilet in ice grey for our guest bathroom. It flushes so much better than our 1.2 GPF toilet in master bath. And it looks great. Love the color.

      When I first ordered the toilet was told that it came with the toilet seat but it didn't $60 more. My wife hates the comfort height it is Too Tall, I had to buy a EZ Go to put underneath for her to be able to use the bathroom comfortably. I was very unhappy with the salesperson who placed the order for me because he did not inform me that the toilet was a comfort height toilet and did not have a toilet seat included with it. Over $400 for a toilet and toilet seat that I'm not happy with it's a shame.

      Robb, my name is Jessica with Kohler Customer Service. I am very sorry to hear of your disappointment with your Cimarron toilet. The only Kohler toilets that come with a toilet seat are the one piece toilets and Complete Solutions that are sold exclusively at Home Depot. If a standard toilet (14 1/2" from the floor to the top of the bowl without the seat on) is more suitable for you, the following link is to our current options: https://goo.gl/Xv3cWf. If you have any questions or need additional assistance, please contact our Customer Service team at KohlerCustServ@kohler.com. We're happy to help! - Jessica P. KOHLER Customer Service.

      Good quality unit easy installation works great. Very quiet the comfort height has taken a little to get used to being higher than what we had grown accustomed to, but both myself and my wife have no issues. I would highly recommend this unit. We also purchased the matching seat.

      Everything we were hoping for
      This fixture replaced an older Kohler round-front two-piece toilet that couldn't flush worth a darn. Based on the Kohler reputation and positive previous experience I disregarded the fact that the older fixture was from the same company and after reading several glowing reviews we picked this one, but in the 1.6 GPF version rather than the 1.28. The clearance was tight, but after careful measurements, I concluded that this one would fit, and it does (the door swing clears it by about 3/4". The unit shipped with the wrong size tank-to-bowl seal, and it was a bit of a nuisance having to go back to find the right one in the middle of the project. The flushing action is quick, quiet, and effective, even with the water level in the tank set at the lowest possible level. There was a problem with the flush valve running after several weeks, and Kohler Customer Service was useless in terms of addressing this issue, sending me the wrong part as a fix. But I found a great fast no-cost solution on line at http://www.justanswer.com/plumbing/8641b-kohler-1-6-liter-toilet-aqua-piston-keeps-running.html. Now we're pleased as punch with our new toilet.

      Flushing Great!
      We replaced our old toilets on a rural septic system with these Kohler Cimarrons recommended by my friend who is a master plumber. The old toilets often would not flush completely and we were worried that it was a plumbing drainage or vent fault. We didn't need to worry. These things flush like crazy! No more unwanted reruns! We also like the added height and seat comfort. The only problem was with shipping. One toilet tank wasn't properly packed and arrived with a crack so we had to wait for a replacement.

      Throw away your plunger. You won't need it.
      I have been vey pleased with this toilet. In the one month since installing it I have not had a single clog. The old toilet would clog 2-3 times per week. Also really like the comfort height and the elongated bowl. The toilet is 1.6 gallons per flush but with this piston design you need to hold the flush lever to get it all 1.6 gallons. If you just do a quick flush and release it still gives you a good flush but you will not have quite as much water in the bowl for the next user. I also adjusted the float height so the tank would be as full as possible. Does a great job of rinsing the entire bowl with each flush. The toilet is fairly quiet and you think it can't possibly flush that much waste but I can testify that it has been thoroughly tested this past month and has not clogged up once!
