: I just bought a house with the second bathroom mostly roughed-in. The biggest problem I have is that the waste rough-in (2" PVC) for the shower is 5-10 degrees out of plumb. I have a 4 piece shower stall coming. How do I work with this? If I try to install the drain in the fiberglass pan and onto to the out of plumb pipe will I be flexing the floor too much and cause premature damage? There is about 1" of space all the way around between the pipe and the concrete.
