We have a standing shower with a strange leak. It was built with a small tiled wall/step that the frame-less glass shower wall panel sits on. I noticed water pooling outside the door after a shower. At first I thought it was the door seal but upon closer inspection it is coming out of the grout. See pics (right where the arrow is pointing). The shower was already in the house when we bought it so I don’t know anything about how it was constructed.
How should I proceed trying to fix this leak? Do I need to re-do the grout? Should I just use grout sealer? Any help appreciated.
Update #1: Thanks for the help everyone. Do ya’ll have any thoughts on where the water could be entering from? The silicone caulking was recently redone. My thought was that I have a hairline crack along the grout somewhere that is allowing water to wick in and and along to the outside.
Update #2: It’s Fixed! Thanks everyone for the suggestions and advice. My working theory was that water was wicking down under the bottom frame and finding its way into the frame attachment holes. This appears to be what was happening. I ended up pulling out all the caulk around the inside of the shower on that side and replaced it with fresh silicone. That seems to have done the trick. Bingo, no more water on the ground!
I would try removing the caulking around the shower pan and redo it. If that doesn’t fix it, basically I would rebuild the whole shower. It looks like water might flow beneath the flooring here, which might cause a lot of problems in the future.
Also, I cant see it well in your pictures, but I’ve found in past remodelling projects that the best way to make showers leak free, is to first place the shower pan and then do the wall tiles, so the tiles are slightly above the pan.
