Centering existing drain to shower insert?
I roughed in the shower drain -in basement- for a bathtub. I have changed plans and would like to switch to shower only but I don't want to dig up concrete in order to position drain for an insert type composite shower. My question is does anyone manufacture a shower insert with enough room underneath to center the drain to the floor drain of shower with a few pvc fittings?:eek:

Not sure about the shower insert, but why not just build up the base to accommodate the extra piping?

Sounds good. Nice simple solution. I'm thinking maybe buid a curb with bricks or form and fill wth sand mix mortar and another "footer" in center at drain. Thanks :huh:

Sounds like more work than 1/2 an hour of jackhammering, 20 minutes of easy plumbing and one bag of premix to patch it.

Yes, this is what I may have to do. Is there something out of the ordinary about recentering the drain without jackhammering the slab? I have a feeling if not installed correctly, with the floor drain going straight to the drain in the shower insert, that this may increase the chance for a leak. It would be really nice if space under the insert is just standard design for an insert so I won't have to pay extra for a special design or loose headroom.

Can't say if I ever saw a shower stall that was designed to be installed with the drain pipes and trap above floor level. It would be a whole other issue if you had no drain pipes handy (sump pump, saniflow type system), but they're right there waiting for you to jackhammer up. Unless your bathroom is hokey already I wouldn't build up a base for the shower, cause that's super-hokey. Not to mention theres probably a p-trap under that slab already. Throw a couple of elbows on that drain to get to your elevated shower stall and you'll never be able to snake the drain when it eventually clogs.
