    My shower developed a leak. The bathroom was pretty old and tired, so it was time to rip it out.

    When I removed the tiles it caused a lot of damage to the plasterboard as well as leaving a lot of the old tile adhesive too. The plasterboard also had some black mould on it where the leak had been. Also, I think it is just regular plasterboard rather than the green moisture resistant stuff that I'd expected for the walls of a shower.

    So, I figured my best bet was to replace the plasterboard.

    One of the walls of the shower is an internal wall; plasterboard fixed to metal studs. The other wall is an external wall which is plasterboard fixed by dot-and-dab. The sheet of plasterboard on the external wall actually spans into the next room along.

    I'd like to replace the plasterboard right up to the corner to make sure I get all the water damage (I can see through the holes in the stud that the water doesn't appear to have gotten behind the stud) but I don't suppose I'd be able to join the new plasterboard as I couldn't get the scrim tape behind the stud.

    I'm a bit stuck on what the best way to proceed is. Perhaps I should cut the plasterboard a couple of inches into the room to make a satisfactory join and just accept that there is a small amount of damaged plasterboard remaining.

    Any advice will be very gratefully received!

    Just dot n dab right up to the corner, if there is a gap between rooms, fill it in with board adhesive.
