UPDATE: Kohler responded quickly and sent a new fill valve and flush valve assembly at no cost. Took off the canister, though, and found the base for the valve was not seated properly and that's what was causing the leak. Disassembled it, got the new value base unit, but it won't fit in any way and certainly not in a way that will keep water from leaking out. The opening for the valve appears to have been cast incorrectly and, when they tried to install the flush valve at the factory, figured "good enough" would work. To their credit, they're sending me a new toilet so we'll see if that one works. While I appreciate their quick attention to the problem I would much rather just have a product that works out of the box. ORIGINAL REVIEW: Toilet looks great installed but seal won't hold so it constantly drains and refills. Not happy. Replaced the sealant ring since that's a know point of failure on Kohler Swirl toilets but still leaks.

Absolutely perfect toilet bowl. I bought it for five bathrooms. The height is really good for any size person. And it flushes very well.

I order 5 for all the bathrooms ... they are great and look amazing

Great toilet! The one piece makes it easy to install and easy to clean!

This is a very nice toilet With decent height.
