Starting bathroom refit shortly which will involve stripping off old tiles/plaster etc right down to the brickwork and removing the ceiling. I plan to use plaster board and tank the shower enclosure and around the bath. Should I use the vapour check plasterboard or will the standard type be ok. Once plasterboarded I'll tape and fill joints then tank the wet areas is there anything else i need to do or can I then tile directly onto the plasterboard.
