Answer This Question

A:  Hello Lisa, my name is Kassi with Kohler Co. I'd be glad to answer your question. The rough-in size is referring to the space between where the toilet mounts on the floor, until it hits the wall. Thank you for choosing Kohler.

    Q:The toilet I need to replace appears to have an 11.5" rough in. All other toilets in the house have 12" rough ins. Does this toilet have enough "give" to work in my space? Thanks for your help.

    A:  Hi Mindy, my name is Meli with Kohler Co. I am happy to assist with your question. The Highline Arc K- will have a 13/16" gap between the tank and finished wall when installed in a 12 inch rough in; if installed in an 11-1/2" rough in this would bring the tank closer to the finished wall by 1/2". Thank you for choosing Kohler.

      Q:My newly installed bowl leaks from below in approximately the middle/front of the bowl when it has water in it. No water leaks or runs from the tank and no water leaks when flushing. What might be my issue? The bolts are tight and wax ring seems set well

      A:  Did you compress wax ring with plastic stand before you set toilet?

        A:  I tried setting the wax ring both ways, directly on the flange and also compressed on the pedestal, same leak from the bowl. I?m pretty confident there is a crack in the trap.

          Worst toilet ever
          I will never buy another Kohler product. This toilet has been nothing but a problem since day one. Never buy a toilet that has a canister style flush system, unless you like going back to jiggle the handle.

          Response from Kohler Product ExpertJan 31, 2023
          Hello, my name is Kassi with Kohler Co. I am sorry for the issues you encountered with your Highline Arc toilet. There may be an issue with the settings in the tank; please review the following settings in your tank and correct if necessary. The trip lever should be taut; remove excess links of chain until there is very little play in the chain when the toilet is at rest. Check that the water level is at the water line mark on the canister. The refill hose must be inserted into the top of the canister flush valve and pushed in as far as it will go. There may be debris in the fill valve as well; this comes through the water line and lodges in the fill valve cap and seal, preventing it from closing completely. Here are instructions for flushing it out: http://bit.do/eoFtJ. Anytime we hear of issues encountered in the use of one of our products, we want to get involved and resolve the difficulties the best we can. Please contact our customer service team at 800-456-4537 M-F from 8AM-5PM CST so we may gather more information and find a resolution for you. We look forward to hearing from you soon! -Kassi D., Kohler Customer Service
            Terrible install instructions
            The instructions on mounting the tank to the bowl are terrible. Had to watch a YouTube video to see that you need washers. It also says “don’t over tighten!” But there are these huge rubber gaskets that seemingly need to be compressed, but how much, we will never know because the instructions are so rudimentary. Also, there was a sizable chunk of porcelain sticking on the bottom of the bowl. This would have made the toilet sit crooked on the floor. Luckily I had an angle grinder to shave it off. I have installed the basic $100 toilets and they were way easier and still get your “stuff” flushed. Not sure why I paid so much to suffer through a terrible install!

              Low Toilet Water Level Caused by "Kinked" Line
              I had a problem reported by other people where the water level in the toilet was very low. After a bit of searching I found the cause of the problem was the black rubber "water fill line" in the tank had a "kink" in it that was restricting the flow of water filling the tank. I was able to cut the line "shorter" to eliminate the kink and reconnect it and this solved the problem and the toilet now fills properly. This has been reported by other people, so is an issue to be aware of. See photo.

                Not working as it should
                The toilet looks pretty but the float valve is not working properly. The tank is not filling consistently on its own. I need to lift the lid and push down on the valve so it fills. My husband wanted to buy an American Standard toilet and I convinced him to buy this one, but now I am thinking I should have listened to him. Not happy with the product

We recommend flushing out the fill valve which will likely resolve this.

                  New Throne.
                  Professional plumbers install the bolts that attached the bowl to the tank could be a little bit longer for user insulation other than that Good product.

                  Something is off
                  This toilet is really nice. Flushes great. Classic design. However, I'm not sure if I received the wrong tank but my take sits about three inches away from the wall. Not sure that I've ever seen a toilet tank not flush to the wall.

                    Lousy execution
                    Kohler, are you listening? I hope so... I bought this toilet today at Home Depot, not my first toilet installation. It was nice that all the hardware is included but what would have been better is if it was actually usable! The bolts to attach the tank to the bowl were too short to clear the bowl and get the nut and washer on it. About a half inch longer would have been great. After two hours trying to make yours work I ended up using my own bolts. Stupid error on Kohler's part.
