KOHLER K-5172-NY San Souci Comfort Height Compact Elongated 1.28 GPF Toilet with AquaPiston Flushing Technology and Left-Hand Trip Lever, Dune, 1-Piece

We like the height, the elongated seat, and the fact that it actually works with low volume water usage! The height seems to me to be correct for adults, especially if you have lower back pain. I have always been skeptical about the low flow toilets. This one actually works. In fact, I replaced all of our toilets after using this model. It has only been a couple of years but so far so good and no maintenance. The elongated toilet seems to help the flush, however, the "target" needs to be further back to help prevent guests from doing a ceramic clean if you know what I mean... The other thing we like is the look. Very sleek and modern.

Replaced older low seat commode.Delivery was excellent from FedEx.

We had this installed by a professional. It meets our expectations of high quality from Kohler. It was shipped directly to us and arrived in perfect condition.

Hands down the worst toilet I have ever owned.Purchased this for the height and the compact elongated depth. It fits perfectly in our small bathroom.Bought in January, 2020 and had it professionally installed since I am not a plumber.From day one, each time you flush it, within 30-60 seconds it starts to run.You can jiggle the handle and it will stop for a few minutes, then start again.Every once in a while we get lucky and it will stop for several hours.I have replaced the seal, twice, as suggested here and on Kohler's site with no success.I have checked that there is nothing interfering with the canister.The chain is taut as Kohler suggests.We have not had a plumber look at it and am very hesitant to spend money on a plumber for something that is/was brand new and never functioned properly.Bottom line, the toilet is a very nice unit but I wouldn't waste this much money for something that does not work and appears to not be supported.In the future I would much prefer a cheaper, old fashioned flapper and float toilet. At least they won't waste water and your time.

We remodeled our bathroom and did it in a modern style. This toilet looks perfect in there. It is quiet when it flushes, uses much less water than a regular toilet and refills fast. I'm going to buy another one when I remodel the powder room.
