    Looking at the bathroom within our straw bale/timber frame home. We've gone for walls with clay plaster inside and lime render cladding outside. Given the bathroom is a great moisture generator we have chosen purge ventilation/extraction via an extractor fan and/or window. So no MVHR.

    Rather than use wool boards, as we are for the sheepswool insulated, hemp/lime rendered internal stud walls and clay plastered rafters, I am considering foil backed plasterboard for the bathroom ceiling, walls. Is it a good idea to hermetically seal this room? And what of the floor? We have suspended timber ijoists which I will be insulating with glass or mineral wool. The plan for the rest of the home is to put a taped 18mm OSB 3 layer on top to act as a vapour check. Your thoughts welcome.

    Our house is conventional brick and block with stone tiles and emulsion painted ceilings. Four adults use the high flow rate shower daily. No extractor fan only an MVHR extract port in the bathroom. I did have a minor issue with the ceiling paint over the shower but Zinsser paint fixed that. Is it really necessary to go OTT on breathable products/design?

    We used 12mm Hardibacker board behind the stone tiles including in the shower. Ordinary plasterboard on ceiling. Hardibacker is hard to cut but bomb proof and great for fixing to compared to regular plasterboard. Sorry not very green.

    Definitely do NOT use ordinary plasterboard for the walls. Maybe moisture-resistant plasterboard, but I would prefer Fermacell or cement-based tile-backer boards.

    We have some lime-rendered bale walls in our wet rooms, but not in areas where they get struck by showers (actually there is one shower that can be pointed at a lime wall, so I've installed a waterproof roller blind on the ceiling n front of it that we pull down before using the shower). On internal walls we've put waterproof panels (Bushboard Nuance) over tile-backer board. My wife dislikes tiles because of cleaning grout.

    Floors are normal chipboard panels, with vinyl over. One room is a wetroom and the vinyl there is contract non-slip; the other rooms have shower trays and the vinyl is just normal stuff.

    I don't think hermetically sealing it is necessary or a good idea.

    If the cement backer board minimises water damage and a resulting strip out and rebuild, then its probably greener than using inappropriate materials that get binned after a few years. Horses for courses in material choice.

    That was my thought process exactly.

    Thanks all. I don't have a problem with using a few cement backer boards in the scheme of things. Noted your points DJH, cheers.
