Our toilet has worked flawlessly for 7+ years with a lot of daily use. I installed this toilet and noted it is a tad more difficult to install than a "standard" USA toilet. However, the differences are, IMO, from superior engineering - especially how to toilet fits onto the floor and the plumbing connects. Any installation shortcut(s) and for sure there will be problems. (Note: I was not compensated in any way for this review - just a firm believer in Kohler products after spending years repairing and wasting money on inferior brands.)

I've had this toilet at two houses. At my current house, we've had it for over 7 years, and still works great. I think it's harder to install than some toilets, but I've had a professional install mine and always had success. If you get the model with the top dual flush button I find that they have been prone to getting stuck for the first month (this happened on both toilets we owed) but after a month or so they wear in and work great. It flushes well and looks great and easy to clean.

We have two of these that are only 6 years old, we had to replace the seats on both in the first 4 years and now we’re on the second set of seats. BTW, the bolts on these seats are notorious for failure, so drilling them out and buying a replacement kit will be part of your plan. Garbage.

Purchased toilet April, 9, 2020 and had installed. Toilet is leaking with plumbers telling me this toilet is known as an incredibly hard install (see towels next to toilet on each side see video). Plumber recommended buying different toilet as he will have to charge me double to fix this toilet as he would just to install another toilet. Also, toilet stains and collects mold (see photo)

We are very happy with our new toilet. It looks fantastic in our newly remodeled bathroom. It's the top flush version. We are a bit confused though, which button is for liquids and which button is for solids?
