Re: 1950s Bathroom moisture = tile, caulk, ceiling issues
I'm 95% sure that the leak is caused by the shower water running down the bath walls. I had my son downstairs watch for leaks, while I was upstairs running the shower with a plastic collar around it so it wouldn't splash onto the walls. He saw no leaks, verifying that it isn't the incoming water pipes causing the leak.

I honestly couldn't tell you how or what the previous homeowner did; we haven't remodeled the house and it's from the 50s, so for all I know -- the tile/grout could be that old. Not sure if it was sealed; is it possible to tell by its appearance? I assume that sealed grout looks a little slicker/smoother than the chalky/rough/porous stuff I've got.

We don't use the soap dish so I'd have no problem removing it if I knew how to put up 2 tiles in its place; we've found a few matching tiles in the basement that we could install.
Right now, we need to keep the bathroom moisture/leak from getting worse. We eventually plan on remodeling the bathroom & perhaps enlarging it within a year or two, so I'm not too keen on ripping out all the tile and starting over right now... but we'll definitely do a vapor barrier and "the works" when we remodel/enlarge the bathroom.
