Have used Redgard on floors hadn't thought of it on shower walls but it should work if it will adhere to the thinset well enough. The literature says that it is a valid application. Expense is more than plastic but still reasonable.

But I am reading a lot of people saying that 2 vapor barriers could cause problems. So basically if I understand correctly, I should use unfaced bats for insulation then a vapor barrier over the studs and then the backer board. Does anyone have any first hand knowledge of Redguard or the similar Laticrete product? I'm wondering if that would be an even better choice as it seems like it would stop the moisture before it got behind the backer board. I'm sure it would cost more than the poly vapor barrier but if I can pull this off, then I would be saving on labor so cost of product wouldn't be such an issue especially if the job is done right. Thanks again for the replies. I appreciate it.

I asked a guy at Home Depot for some advice and he seemed to know what he was doing but I wanted to check with you good people here.

Does this sound right? I want to be sure I don't have any moisture or condensation behind the backer board. Also I was thinking of using Hardi backer. Is this a good choice or is there some other product that might work better. Hope these weren't stupid questions. lol. Thanks
