shower surround questions
I'm having a tub/shower installed as a replacement to the clawfoot tub in my bathroom. The house is approx. 100 years old.
I realize there are a variety of opinions and previous threads dealing with the subject of vapor barriers surrounding showers, but I'm hoping to get some feedback/confirmation on my specific plan, which is to insulate the shower walls with kraft-faced batts, followed by cement board, then a sealer on the cement board (redgard or something else?), followed by tile.
I don't view the batts as a vapor barrier. They will not be tightly sealed, but will just be stuffed in the cavities with some tears in the paper.
Am I missing anything or is there anything obviously wrong about this plan? Is there anything regarding the type of grout or adhesive that I should be aware of since it will be going on over the redgard?
Also, we're installing a ceiling fan/vent and the shower itself will have a glass block window with a vent in it, so the ventilation should be pretty good.
