I've been in this situation .... Water on the backside wall leaking along the framing onto the drywall and down into a ceiling light on the 1st floor. I hit the old grout with a grout saw, with particular attention to the soap dish that was tiled into the wall. Re-grouted, sealed three coats.

Problem fixed. Hope that helps you and others ...

Villa: Do you have any idea how much water soaks onto the drywall, framing and floor sheeting as well as floor joists before it shows up on the ceiling below.

Hey Neal ... you bet. I didn't give you every step I followed . . . In my case, there was a slope to the downstairs celing that allowed the water to run out of the ceiling box to the 1st floor. I cut an access hatch in the closet adjoinging the valve side of the shower through a closet. Close inspection revealed the course of the water while the shower was running. I made the repairs to the shower wall tile and rechecked for leaks. There were none.

I ran a fan to dry out the backside, then sprayed for mildew. No more leaks, so I installed an access door for future plumbing repairs and called it job done.

Zepper10 was just asking about mainentence after a year from new. Anyone with water showing up down stairs needs to open things up.
