: Is this something that we can switch, or are the drains different in any way? The drain that our toilet sits on is appox. 1' from the stack, and the shower is probably 2' away (though hard to tell since it has been built up).
I'm no expert, but that sounds like a pretty big job. I'm going through something similar right now. Do you access under the floor to see how your neighbour's plumbing was set up? I'm guessing you won't in a basement.
I have pretty good underfloor access, so I can see what I'm faced with from above and below (my bath remodel is on the 3rd floor).
Regarding drain size, I believe, a toilet uses a 4" drain flange to a 3" (or 4" drain) and a shower a 2" drain. So you'd need to redo the drains, not to mention all the tearing up of flooring or slab. Plumbing is complex, as I'm finding out, particularly in the DWV (Drain, Waste, Vent) arena.
Good luck,
Martin
