All the bathtub waste and overflow assemblies I've run across are
1.5". I expect a 2" drain, like a shower drain, would drain more
quickly. Does anyone use a 2" drain on bathtubs?
I have an Oatey ABS 1.5" waste show and the female threads for the
spud block some of the outlet. Is there a source for 2" ABS bathtub
waste shoes? Or if I use this 1.5" waste show, is there a point to
adapting to 2" as soon as I can?
