Wall Mounted Toilet Interchangeability?

[Joe Kennedy]

I just installed a Kohler K-18829 in wall carrier. Sadly as I've been doing the project, it looks as though the Toto Aquia bowl has much better reviews than the Kohler Veil(as far as skid marks). I was wondering has anyone mounted a Toto bowl on a Kohler carrier? The specification sheets show the mounting studs and locations for the inlet and outlet are spaced the same but there's no specs listed for the actual inlet and outlet diameter. I was hoping to get some confirmation before I purchase a bowl.

Kind of looks similar. I've wondered that too. I know that Duravit and the TOTO are compatible. I've wondered since Kohler looks similar if it was too.

Well I bit the bullet and purchased a
Toto CT428CFG. I guess I’ll be the guinea pig to find out if it’s compatible with the kohler carrier. Will report back with findings

Good news the toto bowl fit the kohler carrier. No issues so far. Fits, flushes, no leaks

I don’t have a lot of experience with these but I sold plumbing supplies for a couple of years and always wondered how interchangeable they were. They seem to all be close anyway.

Good info.
