Hi LazyPup,

I don't know where you are in the world but I'm in Ontario Canada and I found the opposite to what you've said and I’m not surprised.

On the exterior wall of my bathroom, the wall was covered with green board and behind the green board was a six mil poly vapour barrier.

Everywhere else in the bathroom was regular 1/2" drywall including the ceiling.

Believe me when I tell you that I'm not doubting what you are saying and with no visible signs of the regular drywall deteriorating (after 20 years of use), I suspect that I'll go with my original plan.

I wonder why you can't put a vapour barrier behind green board, that one has me scratching my head.

Many, many thanks for all your help.
