My bathtub/shower on the second floor has a persistent leak. It leaked thru the ceiling and we had all plumbing changed and the tile redone and the leak stopped for about a year. It recently started leaking again. We hadn't closed the hole in the kitchen ceiling yet, so I can see what's going on and I'm a little confused. The drain pipe and the water lines are all dry, the leak is coming thru the subfloor beside the tub, above the drain pipe and water lines. The shower curtain is sealed, so water is not escaping the shower that way and the floor is dry. I cannot for the life of me figure out where the water is coming from. Anyone have any ideas how I can figure this out? Thanks in advance.

It could be leaking behind the tile/wall joint on the plumbing end of the tub, running horizontally to the outside of the tub, down to the floor (still behind the tile) and then under the floor and beyond.

I'd slide the plate that's around the shower arm away from the wall and look closely for a leak at the threaded connection that's in the wall. If that's ok then pull the plate that's around the shower faucet from the wall and caulk behind it. Is there a tub filler ? The leak could also be coming from behind it.

if it has taken more than a year for the leak to start, i would question the tile rather than the plumbing..

It is probably either the tile or the overflow connection to the tub.
