The Kohler San Souci is a popular new toilet released by Kohler in 2015. It has an appealing one piece design, and if you’re reading this you probably own one, or are considering buying one. So now for the big question, “What bidet seats will fit the Kohler San Souci?”

Kohler San Souci Design

The Kohler San Souci is a fashionable toilet with its elegant curved tank and seamless one piece design.  However, its beauty is also its weakness. Due to its “French curve” tank design, the San Souci is not compatible with most bidet seats on the market. There is very limited space between the tank and the toilet seat bolt holes, and the width between the curves of the tank is narrow.  Luckily, the Kohler San Souci’s does have an elongated bowl which will at least allow for some bidet seats to fit.

Which Bidet Toilet Seats Will Fit the Kohler San Souci?

We can confirm that the Alpha JX bidet toilet seat, the TOTO s550e washlet, and the TOTO s500e washlet will all fit on the Kohler San Souci. With the Kohler San Souci, it is possible that there will be a very slight overhang off the front of the toilet bowl. Although this overhang will not be greatly noticeable, this is something that is worth considering when installing a bidet seat on the Kohler San Souci.

The Alpha JX bidet toilet seat will give your Kohler San Souci a great aesthetic along with a bidet seat with great functions. At a very reasonable price tag, the Alpha JX provides all of the necessary features a person would want in a bidet seat.  Packed full of features such as unlimited warm water, adjustable nozzle, heated seat, a sturdy sittable lid and much more, the Alpha JX is one of the few bidet seats on the market that will fit on the Kohler San Souci. The Alpha JX has a tankless type heating system that will provide unlimited warm water after one second of lag time of room temperature water. One underrated feature that the Alpha JX has that bidet seats mentioned above do not have, is a sturdy sittable lid. Although it may not be a feature that will “wow” people, the functionality and usefulness of a sittable lid is unmatched. Whether it be watching children while they’re taking a bath or clipping your nails, a sittable lid has many practical uses that many people do not consider.
