I'm new to your website and I hope someone can explain something for me. I also have a shower drain location problem like devouru's. When I explained how I wanted to use elbows to move the drain position, the local building official said it sounded o.k. However, the unequivocal advice on this website (and others, for the most part), is to relocate the p-trap.
My question is this: As far as the water flow is concerned, how is the "two-elbow" approach different from a regular bathtub "shoe"? Both have two 90 degree turns.
See sketch attached.
Also note that the original rough-in for this future basement bathroom was inspected and approved back in 2004. The IRC governs here in north Georgia.
