Answer This Question

A:  Hello Alex, this is Lisa with Kohler Co. I am glad to assist with your inquiry. The Highline Arc Collection will have a slightly different tank style / design than the Highline Collection. In addition to that, depending on the model number, you may see dimension differences such as the rough-in. Thank you for choosing Kohler.

      A:  This may be a 10" rough-in, measured from the wall, not the baseboard.

        A:  Hello Kathy, this is Lisa with Kohler Co. I am glad to answer your question. At this time, we do not offer a toilet that would be compatible with a 9" rough-in. Thank you for reaching out to Kohler Co.

          Q:I have two toilets to replace. One has a 9 1/2” rough in and the other has a 11” rough in (distance from the floor bolts to the wall molding). Would this toilet work for both?

          A:  Roland, my name is Jessica with Kohler Customer Service. I am happy to assist with your inquiry. K-78206 is a 10" rough-in. When installed as a 10" rough-in there is a 7/8" gap between the finished wall and tank; this would not work with a 9-1/2" rough-in. Thank you for choosing Kohler.

            Toilet upgrade!
            [This review was collected as part of a promotion.] We had replaced the toilets in 2 of our other bathrooms with Kohler toilets and still needed to replace the one in our primary bathroom. To say I was beyond excited to receive this toilet ( in exchange for my honest review) is an understatement! To my delight, this is the step up from the Kohlers that we already have and love. The seat is comfortable to sit on and is easily removable for cleaning. The quiet close close lid is also a nice touch. The rim under the seat seems to be designed for easy cleaning….no hard to reach crevices. Seems to be able to handle quite a bit of toilet paper in each flush without clogging. The flush itself is pretty loud but quick. I love it and am so grateful to have received this!

              A Really Nice Toilet
              [This review was collected as part of a promotion.] What a really nice toilet! It is is really easy to install with instructions and fits perfectly. I love the fact that it has a slow close toilet to keep from slamming shut. The toilet is also just the right height and fills with jibe right amount of water to help keep clean. The seat is comfortable and I would definitely recommend it.

                If you are tall, this is the toilet for you
                [This review was collected as part of a promotion.] The elongated bowl makes it easier for coverage when sitting that long sitting feeling where your butt gets numb is no longer there. The chair height is also taller so this helps with sitting and standing easier. Definitely love this more than the toilet that I had existing the sleek look and design upgrades, the bathroom without even trying, highly recommend the highline arc 10 inch Ruffin elongated bowl really is Kohler‘s best selling toilet family number one

                  Very nice looking
                  [This review was collected as part of a promotion.] Unfortunately I had a surgery immediately after receiving this so I haven’t been able to install yet, but it is packaged well to keep it safe and is a very nice looking toilet. Excited to get it installed!

                    Perfect Addition
                    [This review was collected as part of a promotion.] Fit was perfect, installation was easy and made our newly remodeled bathroom look fantastic! I can’t speak much on the technical things about this toilet but it looks and works great. I really like the elongated seat and the height is perfect for my household.

                      Pretty design but less than expected performance.
                      [This review was collected as part of a promotion.] I was excited to have this installed after I received it complimentary! I think it has a beautiful design and I love the elongated seat, the one I had previously was small and rounded. After installation, I noticed it didn’t seem to flush great. My old one was about 15 years old or so and seemed to flush better. I will say it seems to use less water.

                        The neatest toilet!
                        [This review was collected as part of a promotion.] The Highline Arc by Koehler is a very stylish and sophisticated little toilet. We like that the tank is shaped very stylishly and looks very fashionable. We added a simple bidet to make it even more effective. The tank is a water efficient tank. The kit came with everything you need to install including a wax ring. My husband said it was simple to install and took less than an hour.

                          Elegant looking toilet!
                          [This review was collected as part of a promotion.] The Highline Arc Comfort Height two-piece elongated chair-height toilet looks great in my bathroom. I really like the elongated style and flared tank. It gives it an elegant look. This toilet is chair-height, so it makes it easier to sit and stand. It has a powerful flush which I like because it helps eliminate clogs. It is quiet when it flushes. The bowl is quite easy to clean and wipes up well. It comes with everything necessary for installation. I had my handyperson install it for me. It took him a little over an hour to install it. He first had to remove my current toilet. I absolutely love Kohler products. They are high quality and I find them to be exceptionally durable. I love my new toilet.

                            Great taller size
                            [This review was collected as part of a promotion.] This toilet sits a little higher than the standard one I had which makes getting up and down easier. It has a strong flush but is still quiet. The slow closing seat is a great help since my kids love to slam the lid and now they can’t. It was very easy for my husband to install. I love the elongated bowl and the tank design is more stylish than standard models.
