The house came with a Delta shower valve. When I went to replace it with a Kohler valve and trim kit, I found that the Kohler cartridge doesn't appear to mount to the rough in valve.
From what I can tell I have this Delta universal rough in.
Am I correct that I have a mismatch?
This is the new Kohler cartridge
And this is the existing Delta cartridge (still trying to get it out).
EDIT
Okay, I got it out, and they definitely do not match.
So does Kohler make a valve that'll fit this "rough in"?
