The plastic cover in my shower drain cracked. I bought a Moen drain assembly (couldn't get just the cover), but the cover is a bit too small. I thought it would be a standard size.


The outside diameter is 4.25" and the 1/4" "snap-in" part should be 3", but the Moen is about 1/16" too small.

Take the broken plastic cover to a local plumbing supply house and see what they can come up with. If that fails to work, you can simply silicone caulk the new cover in place (let dry overnight) and you should be all set for awhile!
