Questions & Answers

SILLY QUESTION BUT WHY DOES IT LOOK LIKE THERE'S ONLY A LID AND NOT A SEAT TOO?

Asked by: LEAN
The Koehler seat cover is designed to encompass the seat itself whereas the standard cover simply lays on top of the seat.The Kohler cover acts like a cover and skirt. As a retired professional I like this cleaner look. Though this seat is cheaply made I'm sure another manufacturer has a more durable approach.

is the seat a slow close seat?

Asked by: MACy
There is no spring or piston action closing. Strictly hand operated using the laws of gravity.

We have a very tight fit in our bathroom so if the toilet is too deep we will not be able to close the door. Is the Depth measurement (27.5") include the distance to the edge of the bowl that sticks out a bit farther or just to the farthest point of the base? Its a little hard to tell from the diagram. Thanks.
Asked by: Steve
According to the Kohler cut sheet the 27-1/2" specifically denotes the bowls lip edge. The base dimensions should be to the right of the page. Please keep in mind this dimension is based on the 12 inch center rough or the floor opening you see to the left below the base in the drawing. If your rough is 13 or 14 inches, which it could be. You will be adding another inch or two to your protrusion. Please refer to my previous post with more detail and a possible solution to your door.

I read that some of the Kohler seats in other toilets are made a cheap plastic. Is this a firm seat or is it plastic? Thanks
Asked by: fh
Everything is plastic today. This seat that comes with the toilet is lightweight plastic. We are comfortable with it but you can always get any store shelf elongated seat. Heck get a heated or fur lined seat.

San Souci 1-Piece 1.28 GPF Single Flush Elongated Toilet in White is rated 4.4 out of 5 by 64.

I know it's expensive but if you plan to keep it for years you won't be disappointed. It weighs in at 94 pounds and is rock solid. I'm not sure why two piece toilets still exist after installing and using this. It's a much better design and looks, in my opinion, a lot better. I was a little skeptical about the 1.28 gallon tank at first but we haven't had any problems with it, at all. To fully test it, my wife wasn't really happy with this, I flushed a few bananas. First a half, then a whole one. Just for fun I tried 2 at the same time. Not a single problem with any of it. Everything about this toilet is top notch. From the bolts holding it down, to the no slam seat with a lid that covers the actual seat, I can't imagine anything better than this. One more thing. The instructions say to use a wax ring on install but I choose the fancier and a bit more expensive toilet gaskets and had it installed in under an hour.

Rated 5 out of 5 by from We purchased three San Souci 1-Piece 1.28 GPF Single Flush... We purchased three San Souci 1-Piece 1.28 GPF Single Flush Elongated Toilets. The replacement and installation, done by our plumber, was easy on the two American Standard toilets. The replacement and installation of the Kohler toilet were challenging. The water line was in the way of the base of the new toilet since it's placement was close to the wall in the back and has a wider base. He was able to get it installed. The toilets are great, they have a lower smaller tank, which flushes fine. It seems like it will not have enough water and power to completely flush, but so far we have had no issues after 2 weeks of use. We do like the comfort height and the raised height of the toilets. The slow closing seat and lids are also great. The only thing I would like an option on is the handle color, we have brass in one bathroom and would have preferred a white handle. We also had trouble with one handle sticking. It works fine now, so it probably just needed to be flushed for a few days to break it in. We recommend this toilet and would buy it again. Finally, Home Depot's service and delivery were terrific!

I recently upgraded the toilet in my bath to a new Kohler San Souci Comfort Height One-Piece Elongated Toilet. This is the second San Souci toilet I have owned and really love the design. I’m very impressed with the performance and sleek design and contours of the toilet. The integral tank on the San Souci one-piece toilet is much smaller than a conventional two-piece toilet, but has sufficient capacity for the 1.28 gpm flush using the efficient AquaPiston Canister flush system. It has a comfortable height of 16.5 inches and a shallow depth of only 27.5 inches, making it ideal for small spaces. It also includes a soft close toilet seat that snaps on and off for easy cleaning. The one-piece design prevents leaks common in two-piece toilets from holes attaching the tank to the bowl. Cleaning behind the seat is also easier with a one-piece toilet. The only negative aspect of the San Souci Toilet is high cost, which is common with all one-piece toilets. However, the quality and functionality of the San Souci toilet are outstanding. Highly recommenced!!

Our Kohler Sans Souci toilet is only two years old, yet we've repeatedly replaced the inner tank parts because on a weekly basis the water flow isn't shut off by the gasket. We have to manually move and jiggle the gasket, sometimes even having to wipe the rubber seal. This happens WEEKLY. After only two years, we are seriously contemplating buying a new toilet. It will NOT be a Kohler.
