I agree. If you really wanted a steam shower, you should have put in a vapour ######er (such as the 6 mil poly that they use on your exterior walls) on all the the walls and on the ceiling in the washroom (prior to installation of the gypsum board), and then used a fibre glass faced, mould resistant gypsum board - such as Georgia Pacific Dens-Armor (where you don't have tile), and Georgia Pacific Dens-Sheild, where you do have tile. You can get similar products from CGC and from Certain-Teed. This would be as a minimum. You definitely don't want to use a paper faced gypsum board product (they will sustain mould growth).
