follow up on shower floor:
i finally got the shower basin out after going at it with a pry bar and a hammer. was sadden to destroy it because it looked custom made. it was sitting on a 2×4 frame filled with sand/concrete mix. it seems that the bath room was an addition to the house. when i got to the drain i was very surprised. it seems the plumber didn’t want to raise the basin to high so he punched a rough whole in the slab for the p-trap to protrude lower. is this common and am wondering the long term effects of a whole in my slab. this whole has allowed termites in (the reason it was removed in the first place) and tree roots to come in.
