Im a first time home buyer of a two-story house with 4 people taking a shower twice a day. Problem- I just bought this house 3 months ago and I already have a leak. Bathroom has a stall shower that leaks sometimes to 1st floor and has damaged the ceiling. Called plumber but he found nothing. Leaked again and left water running plumber still found no source and removed nice chunk of ceiling. Called another plumber and he said it was the shower pan. Had 3 estimates and decided I would redo the bathroom since they can't match my wonderful tile. It's been a month now since all this and ready to move forward with bathroom remodel. BIG PROBLEM.........It hasn't leaked again since last shower pan test. Is it the pan? Shouldn't it still leak if it was? Still don't know what the problem is or was or if I should just do the remodel. Any suggestions before I gut out my wonderful bathroom. HELP PLEASE!!!!
