So today I took the drywall out in the room behind my bathtub. My waste and overflow pipes are concreted into the slab. Is there a way to keep the old pipes or do the waste and overflow pipes have to be replaced? Also I have attached a picture of what it looks like. The concrete mixed around the pipes seems to be more of a gravel mix and I believe my drain pipes are galvanized steel.
