The previous owner did a fantastic job of tiling the shower room. It lasted about a year before the grout started to crack and eventually a couple of tiles came off. B&Q cheap white tiles bonded directly to plaster board. No backing board or tanking.
I wasn't in a position to do anything with it then so I raked out the broken grout and stuck the tiles back on to keep it usable. Probably not a good decision but it lasted a bit longer this time.
Now I want to do it properly. I also want to replace the shower with a shower/bath and replace the wall and floor tiles. Unfortunately the cheap tiles go all the way around and from what I've read on this forum it will be easier to replace all the plasterboard to get a smooth service.
2 of the walls are exterior but the house is brick skin over timber frame so they I believe they will be some sort of plasterboard, perhaps with an insulation and/or moisture barrier behind the board, I'm not sure. If I remove this board will it be ok to just replace with one of the water resistant backer boards or will I need something between board and outer insulation?
(Incidentally, of the two walls of the corner shower, the tiles have only come away from the interior wall. The exterior wall substrate seems superior)
I will be fitting the new bath into the same corner as the shower is in now so I can use the current shower (digital shower fed from the ceiling). Do I just use backer board on the two walls adjacent to the bath or shall I do the entire room to cope with moisture? It is only about 2mx2m square. Do I board the floor? (again I'll probably damage the current floor pulling up the tiles.
Finally, how difficult are these boards to work with and put up so everything is nice and even?
