rstout69 posted a bathtub leak problem, in aug. '08 and that is exactly what mine is doing.
It leaks in the basement below the shower. You can see that the water has traveled. So we tore off the bottom of the wall in the bedroom on the other side of the tub/shower. UGH all moldy insulation,etc. We cleared it all up and took a look see while we turned on the shower. Like rstout69, nothing happened until someone stood inthe shower. But your solution,
to make sure that sure you caulk good where (in our case ceramic tile wall) wall meets tub lip. We have done this several times in the last 2 yrs...YOW.

..each time I would fill the tub with water while I caulked and it set. Only to have the problem return. It is NOT the drain, or the over flow, or any gaskets by the spout fixtures. We can see clearly thru the wall now that the water IS coming from the lip when someone is in the shower. How else can we caulk good between the ceramic tiles and the lip.
Immediate help needed
thank you
Bob :thumbsup:

Hey, thanks to all who offered advice. I finally FINISHED the bathroom.
I put up 'cement board' on the wall, where it meets the tub, and then did the necessary 'fixins' for that. I left the CBU up off the tub edge at least 1/8" so water does not wick up the board. then put back up all the ceramic tiles and re grouted. Sealed the grout, and then after all that dried, I put 2 100# weights in the tub, and then filled the tub with water....then used the 'new' 100% silicone caulking around the edge of the tub. so just waiting for the first shower to be done and then it's a wait and see process. Before with the 'wrong' silicone caulking usually about 1-3 months after, it would start leaking. That is when ''as I have found out now'' the caulking would crack, and it was sooo hairline we cud never see it.
Will keep you posted, and THANKS A MILLION FOR ALL THE ADVICE....

I believe it will still leak. What you need to do is take the escutcheons off that are around your tub valve and fill those holes up with caulk if it is a three handle valve if a single handle put caulk all the way around the perimeter of the hole. then put you escutcheons back on and caulk around your escutcheons.
