In our house, there's an upstairs shower and toilet. This bathroom was originally part of the master bedroom but was partitioned with a plasterboard wall.
The shower "cubicle" is in the middle, against the plasterboard wall. There are two plasterboard walls on either side of the shower base, and there's a folding door on the fourth side.
On the back wall, some of the tiles have been falling off. We had this issue around ten years ago. We then had the inside of the shower cubicle redone. This involved taking all the tiles off, removing the plaster and plasterboards and replacing them with newer ones, replastering and retiling. We also had a new shower tray installed. The old plasterboard on the back was warped.
Since then, a few years ago, the tiles came off in the same place. The tiles are 6" x 6" and the area is 4 tiles x 3 tiles, about two feet below the mixer. It's always in the same place. We've tried drying out the underlying plaster (it's damp) and regrouting the tiles but it happens again and again.
I don't know where the water is coming from - we have a mixer shower and the tiles around the mixer are fine. In fact, all of the other tiles are fine except this one particular area.
Any ideas on what's causing it? Is it a leak? It doesn't seem to be the mixer, so where's it coming from?
