Okay, in my case I am kinda free to do anything at this point. What would you suggest? I don't like the masonite bathroom board for the same reasons. Locally, the Lowe's has yellow board, which has no paper. I was going to use that. I don;t think I'm up to tiling yet. At least I'd rather not be tiling around a fiberglass shower surround. Seems pointless to me.
I have lived in a house for 30 years that has non green sheetrock in the bathroom, and around and above the bath tub. Has been repainted with primers and mold resistant paint and no signs of breakdown in the last 12 years since the repaint. So I figured the yellow board would work fine. by the time it breaks down, we'll be ready to re-do again.
But I am open to suggestions.
