my upstairs tile shower is leaking in 3 areas through the drywall onto my kitchen table. All three of those areas on the shower threshold.
- at the base of the threshold where it meets the wall outside of the shower. (the shower door isn't sealed properly and it trickles between the wall and the door onto a crack in the grout)
- inside the shower and inside the shower door, where the tile going up the threshold meets the tile on top of the threshold. There's a crack in the grout.
- same place just a bit over.
