Our ensuite bathroom was renovated 1 year ago, and now our shower stall is leaking. The shower stall is completely tiled with cross cut travertine. We initially noticed that the grout between the floor and walls had cracked, so we regrouted and then siliconed the corners, but it is still leaking. I opened the wall behind the shower to make sure none of the pipes are leaking, and they are all dry.
I opened the ceiling below the shower and found the water is leaking through the above subfloor and the pipes appear to be dry. It seems that the water is getting under the tiles and working its way along to a seem in the subfloor and dripping from there. When we stop using the shower for a few weeks, it then takes a few days worth of showers before the leak starts again.
I don't know where to go from.

Hi Doug, you've done all the right things and came Up with the same answer I would have. I would concentrate on the area where the shower stream hits the tiles. We pan out our showers with a 6 to 8" lip. Your leak is above the lip and runs down the wall outside the lip. Try siliconing the grout where the stream hits. That's where you'll find your leak. Good luck, Tom
