Easy install
Easy installation with included hardware and it looks great. We are on septic so appreciate the fact that it's HET (1.28 gallons per flush).

    Missing rubber piece on toilet seat/board. No QC?
    Purchased 3 of these for our remodeling, so far the first one is missing of the 2 plastic pieces that attached to the board (see picture). I searched everywhere inside the box and can't find it. Hopefully the next 2 are going to be better.

      Nice toilet but needs better quality assurance
      Purchased two - one was perfect but the second had very low water in the bowl because the refill tube (part K-1248134) was kinked. Kohler shipped me a new one, but it took several days. Factory should not have let it ship with this problem.

        A great toilet at a great price. Easy to install. Pick up a thick wax ring and be certain to make sure the tank is secured to the bowl, tighten the nuts and bolts. Highly recommend.

        Being that my toilets were both the standard height water guzzling toilets of old, anything halfway decent would be an improvement but so far everything is going well. My plumber did the install on both and he had no complaints. I initially wanted a dual flush for my bathroom but my plumber pointed out this toilet was just as good for water conservation. After that I ordered another for my master bath and I am very pleased with both plus they look so darn good. It has a very quick flush which is strange at first, still a little odd to me, but I keep reminding myself of how old my original units were. With my old toilets you had to grab the handle but with these the gentlest push of the handle does the job. My mother was so impressed with the powerful flush and the quick water refill that I’m thinking of upgrading the toilets at her house as well. As for the seat, I don’t like the light weight plastic but I’m guessing that’s needed for the slow close feature which by the way is a very very slow. I may end up switching the seat out but I purchased this toilet for the size, both of my bathrooms are very small, height, and low water consumption, not the seat. Granted I’ve only had these toilets for a few weeks now but I’m not anticipating any issues. Great toilet with a great price.

        mine came with the wrong toilet seat
        Bought and installed one this evening. The toilet itself seems just fine. Mine came with the elongated seat that doesn't match the round bowl. Quality QC Kohler!! Now I have to try and find another seat that fits this darned thing.

          My Kohler Highline Arc works well with a powerful flush. I gave a four instead of 5 because it was missing a part.
          The toilet was rather easy to assemble. All parts were in the box with the exception of a small insert that fits under the toilet seat for stability. It only had one. I have no idea how to order this little plastic piece that was missing. Other than that, I am very satisfied with the performance of the toilet and it's height.

            Works great! And the flush is so quiet! I wish I could have found it with a 10-in rough in for my other bathroom.
