Hope someone has some great advice for me, I have a situation with the tiles on the outside of the shower curb. The bathroom was renovated about 8 years ago by a previous owner. We have lived here about 3 months, and when we first moved in I noticed one tile was a bit loose on the right exterior side of the curb. Some grout was missing, and the tile was pushing forward. So, this week I had a look, thinking there may have been some water seeping in there and loosening the tile. I realized there were quite a few areas around the top of the curb where water could have been getting in, although we are pretty careful and always swing the door into the shower. I popped the most obviously loose tile off, and realized that someone had caulked along the floor recently, which was was was essentially keeping the tile on the wall. There was mold and wet backer board (I think...it was green on one side), so I pulled this out and pulled off the 6 or so tiles along the curb. I cleaned out the wet board and this is what I am left with.
I know there should be a moisture barrier, I did not see one until I took the photo where you can see the thin orange line. After I cleaned out the sides and saw the liner on the inside of the shower area I realized the liner must be orange. It just comes over the top of the curb but obviously does not extend down in front. I can see concrete under the tiles on the top of the curb and along the side where it meets the wall. It looks like there is a gap there, could the water be getting in through the sides of the doorway, where the vertical tile meets the curb? The wood is wet, but not rotted, and the wetness only seems to extend along the curb. After only a few hours it is much drier. I cannot see if there is water under the shower but we have no issues in the ceiling of the kitchen which is below the bathroom. However, when I reach up to feel the drywall behind the tiles it is damp so I know I have to remove more tiles to see how far up the wetness goes.
What do I need to do? Can I somehow repair this without damaging the rest of the curb? Does anyone have any advice for me? I have tiled my own backslash in the kitchen and done minor tile repairs before, but nothing where I am concerned that the initial job was not done properly. Thanks for any suggestions!!
