Also, there are no leaks, and it uses only 1.28 gallons of water per flush. With its lovely design and outstanding features, this is a nice toilet to invest in.


Question: Can I install this toilet in the restroom?
Answer: No, you can’t. This is because the toilet is not ADA compliant. It is a requirement that only ADA compliant toilets should be installed in restrooms or public areas. But the Kohler San Souci is a wonderful toilet for homeowners or offices.

Question: Can I install the toilet by myself?
Answer: Though this is possible, it is not recommended at all. This is because the San Souci one-piece toilet is quite heavy as the tank and bowl are adjoined together. Installing this toilet by yourself is very risky as you may drop it or damage it while installing it. You should get a helper to assist you in proper and safe installation.


  1. I would not invest in this expensive toilet. It flushes by itself as it is touch less. If you go away for a week it could be going off 300 times before you get back. You only know this because your water bill is off the chart.
