Plasterboard on bathroom wall

[Dan Fitchie]

I've put up marmox backer boards on 3 of the walls in my small bathroom including the wall that holds the loo and basin, side of shower and shower itself. I've bought normal 12.5mm plasterboard for the remaining wall which is furthest away from the bath/ shower (about 1.5m away) to try and save some money, but I'm questioning whether its going to be ok to use. The wall won't come into contact with water directly but probably condensation with it being quite a cold room.
I was just wondering on peoples opinions on this?
All 4 walls are going to be tiled by the way.

Thanks.

Oh I see, well the tiling place gave me this primer for the cement adhesive ProPrime IT - Instarmac - http://www.instarmac.co.uk/ultratile-products/proprime-it/
Is it the same sort of product as sbr?

No, that is an acrylic primer not SBR. It should work perfectly well so long as it is definitely not in a splash zone. Most of us use acrylic primer day in day out.

Thanks for the info folks, I think I'll get some sbr for a bit of piece of mind. I'm assuming bal bond sbr and everbuild bond sbr do the same. Does it just form a waterproof/resistant coating on the boards then as well as improving adhesion? Should be able to return the acrylic one.
