      A:  Ok

      by|May 8, 2020

        A:  If the lid is supposed to be slow close, then contact Kohler customer service. I have many of their products and they have always made things right with us.

        by|May 8, 2020

          A:  I may be wrong but on mine it did not advertise when I got it that it was a slow fall on the seat. On mine I just bring it up and lower it by hand so no issue

          by|May 6, 2020

          A:  The soft close seats are extra and not included

            Q:Why is this an option if it's not in stock and not deliverable? Is this an item that *will* be available? Is it discontinued? Please assist. Thank you.

                    I never write reviews.
                    I literally don’t write reviews but this annoyed me. Had this toilet for a few years, cleaned it with a Rubber brush and toilet bowl cleaner. The white is rubbing away from the inside. When I emailed Kohler they sent me cleaning instructions and said due to the age they can’t do anything. The original toilet in the house was at least 20 years old. This didn’t even make it to its 6th birthday.
                    Response from KOHLER Customer ServiceJun 28, 2018
                    Hi there, this is Laura with Kohler Co. I am sorry for the issue with your Cimarron toilet. This is a vitreous china product which doesn't experience the finish rubbing away. Please email our Customer Service team at KohlerCustServ@Kohler.com with photos of your toilet so we can determine what is happening and offer a resolution. We look forward to hearing from you! -M. Laura K., KOHLER Customer Service

                      Can’t go wrong!
                      Had this and couldn’t source replacement parts, so replaced with another brand, not as high, not as good!
                        One Challenge With The Install
                        Only installed a month ago, but so far seemingly a very good toilet with no finishing issues with the porcelain out of the box (I had seen this on some other non Kohler toilet reviews). Nice to have everything included such as mounting bolts, wax ring and soft close seat and lid. The only drawback, making it a 4-Star review, were the tank mounting bolts. The bolts seemed very short and with the attached rubber grommets seemed even shorter. I could barely get purchase on the bolts with the nut and it took some fiddling to get both sides attached. Thereafter, it was a bit of a concern about over-tightening due to the short length and to make sure the rubber seals worked. No idea why these bolts aren't a bit longer or that the mounting system isn't more intuitive. Could use some work in this area.

                        Good toilets - great price from Home Depot
                        Bought three of these toilets a year ago for our house. We have been very happy with how they work. As we are a bit older now, so the comfort height is a must. Liked them so much, we just bought three more for our retirement home renovation. The complete package from Home Depot is much cheaper than the price from a bathroom fixture store which appears to have to order the individual sections at a higher total cost.
