Kohler K-4636 Reviews

Rated 5 out of 5 by from A suprisingly good toilet seat! We bought two Toto elongated toilets but after trying the Toto seats in a showroom I decided they were extremely uncomfortable so we only bought the toilets without the seats. I went online and looked for soft close, elongated seats and this one seems to be the only other existing brand besides Toto, who invented the soft close seats. I bought one very cautiously. At first it seemed a little uncomfortable, the shape of the rim is slightly sloped down towards the toilet bowl which gives at first an odd sensation as supposed to seating on a regular flat profile toilet seat. After a few uses the whole family got used to it and we all like it. The seat is extremely comfortable and somehow ergonomic. I strongly recommend this seat especially since at first I was doubting this design very much. One design mistake I made: I bought one gray one for a white toilet in an attempt to be different and match my white and gray powder room marble colors. It was a major mistake! Toilet seats have to be the same color as the toilets otherwise they look very bad. So now I have an extra gray seat, maybe I'll buy a gray toilet for the third bathroom one day!

Rated 2 out of 5 by from Very Uncomfortable Now I realize that many don't plan to site on the can as if they are going to watch TV or something, but this seat has a goofy taper to it that make it uncomfortable to sit on. Seating on it for even a minute seemed to bring pain. I ask my wife what she thought after I installed it without saying what I thought and she said the exact same thing. I ended up getting a Kohler K-4774 Brevia Q2 Elongated instead.

Rated 5 out of 5 by from Accurate, Reliable and Timely This was just the last item ordered from Faucets Direct in re doing 3 bathrooms, from toilet seats to slide bars in the showers. Everything came as ordered, quickly and in good condition. Kohler products come with clear instructions that make it easy for anyone with basic tools to do the installations. I know that I will be ordering from this company again.

Rated 5 out of 5 by from Amazing It doesn't go BANG in the middle of the night anymore. Pretty amazing! Having read most of the reviews, I was a little on the fence. Nearly everyone loves it, but there are some that returned it because it quit working. After about a week, mine also quit working. After a close look, I noticed the little white cylindrical pieces underneath had started to back out. Pushing them back in would fix it, but they wouldn't stay. I bought a $1 part and fixed it. I put a spring loaded toilet paper holder in between the white pieces. It has not failed to close quietly since. In short, WE LOVE IT!!

Rated 1 out of 5 by from Broken Toliet Seat We ordered two of these seats and both were broken when the plumber went to install them. We ordered two with one being a extra. We were very surprised to find both broken in the original packaging. Faucet Direct packing looked fine. Our only thought is that they were broke in the manufacturing process. Faucet Direct did not question our return and immediately refunded our money. They are great.

Rated 1 out of 5 by from won't soft close the seat will not soft-close, the lid does, but not the seat
Date published: 2014-02-16
Rated 4 out of 5 by from Comfortable seat I wasn't sure when I first got it if it was what I was looking for since we were replacing a Kohler wooden seat that was original with the toilet. But after installing it, I was glad this was my selection. Although it is plastic, it is a very comfortable seat and is much easier to clean than a wooden seat.

Rated 1 out of 5 by from Snap off feature not a plus... This seat was fine except for the fact that we could not get the hinges to fit snug and secure due to the easy snap off feature. Had to return this item for another model without snap off feature.
