I had three of these installed in my new home by my plumber. It was immediately apparent that ALL THREE lean to the right side! I went back to the store and checked several in the boxes and they all also lean to the same side! See pictures below.

    defective out of the box
    out of the box, the fill valve is not working properly. it extends over the top of the tank. When you put the tank lid on, it presses valve down and water continues to fill.

    Toilet is ver good, but......
    I ordered the toilet based on the measurements on home depot website. However, when I installed it with help of a plumber, the tank lid seems to be too bulky and he was unable to fit in the gap under the banjo counter top. I called Kohler customer support to see if they can help me find some other slimmer tank lid that can fit this toilet and they had no interest to help and quickly ended my call. I am stuck in this situation now and looking for some ideas how I can solve this problem. Lesson learnt the hard way, next time I am buying a toilet I will take a measuring tape with me and check measurements on the display unit.

    Hello LazyBoy, this is Laura with Kohler Co. I am sorry for the issue with the tank cover for your Cimarron toilet. All tank covers are designed for specific tanks and are not tested for fit on any other tanks. The tank cover 1383446 is the only tank cover that is guaranteed to fit this Cimarron tank. Please email KohlerCustServ@Kohler.com with any questions. We are glad to help. Sincerely, M. Laura K., Kohler Customer Service

      Looks pretty but cleaning challenge
      Installation was easy and everything you should need is included, though I needed to buy a different was ring as my flange wasn't flush to the floor. It looks good and works like it should. The big problem with this toilet is the weird lip design. I can already tell it's going to be hard to keep clean over time. You can't easily get a toilet brush in there. If I could go back, I would not buy this toilet on this basis.

        The Kohler Cimarron Rev 360 2-piece 1.28 Gpf Single Flush round-front complete solution toilet (white), which comes with bowl, tank, seat, wax ring, supply line and floor hardware. I installed this toilet to upgrade from the older toilet I'd had in my home since it was built almost 20 years ago. I had it professionally installed with no issues. Looks nice, much nicer than my old cheap standard toilet. This quality toilet is ADA Compliant, ASME Certified ,CSA Certified, and EPA Approved. Includes a 1-year limited manufacturers warranty. I received this toilet at no cost in exchange for a honest review.

        Toilet Broke
        My plumber installed the toilet. They next day I saw that it was leaking. The plumber came back to tighten the bolts, but water was still leaking between the tank and base, he even removed the tank and reinstalled it, but it was still leaking and the base ended up breaking because the bolts were too tight. I returned the broken toilet and bought different toilet. It was a hassle.

          Nice look, but floppy handle, loud flush, poor design for cleaning the bowl
          Really "pretty" toilet that fits well in our small space for a boy's bathroom. However, I'm disappointed that the handle is quite floppy. I had the plumber take a second look at it, and he could not tighten any more. It's just the way it's built. Also, the flush is quite loud. Unfortunately, that's a huge minus for me as my goal was to be able to flush in the middle of the night and not wake anyone else up. Finally, there's an odd sort of lip around the toilet bin's bowl. So if you use toilet bowl cleaner to clean your toilet, the solution gets stuck/sits in that lip and it's very hard to scrub out with a toilet brush. Just a bit of a bad design for cleaning. It's nice looking, but I probably wouldn't buy this model again.
