waterproofing new tub


Hey guys Im remodeling my bathroom and its a total gut and rebuild. I'm about ready to install the tub but have a few questions i want to make it as waterproof / water tight as possible. I'm going to be tileing inside the shower. this is what i plan on doing please help me figure out if what i'm doing is ok or if i need to make changes. I plan on installing the tub than installing a plastic vapor barrier directly on the studs behind than I plan on installing cement backerboard, and than i plan on installing a waterproof membrane on top of the backerboard like (LATICRETE Hydro Ban) or (Red Guard) something that can ust be painted on and than I plan on installing the tile directly over that. How does this sound I want to make sure it's as water proof as possible any help or pictures would be great

I don't think that will work well. You would have a double vapor barrior... Either use the plastic or the Hydroban / Redgard. I used Redgard for my bathroom shower...

There is not limit to the amount of effort you can use to waterproof a shower wall... and at the end, there's no guarantee it won't eventually leak.
30lb Felt paper over the studs would be better/more durable than plastic. I see no need to apply a second membrane over the backer board. It might actually cause some adhesion problems over time on the wall. For added sealing, use a good sealer over your grout and you should have a well built shower wall.
You reference both a shower and a tub in your question, so I'm unclear as to the floor of the project.
Hope this helps,

Waterproofing the board is the best insurance you can get---backer board and tile are not water proof---

Some water can and will get behind the tile--so waterproofing the face of the board is the best plan---

Sealers do not waterproof the grout---their only purpose is to make the grout less likely to stain---

The floor will be a tub I just call it a shower out of habit lol thanks for all your input I like the idea of the waterproof membrane (red guard) on the backer board but if I go that rout is the barrier or felt on the wall needed or even a good idea at that point what else can I do to help this issue ?

When you waterproof the face of the board--no vapor barrier is needed on the studs---

That is considered a double vapor barrier and is not good---

I agree that a surface membrane is by far the best way to go and never use both surface and plastic or tarpaper over the studs. BTW, tarpaper is not a waterproofing, nor is it a vapor barrier. At best it's a vapor retarder, it's permeable.

In the case where there is faced insulation for an outside wall, I would simply slash the facing and let it breathe.

Vapor barriers are a very confusing subject and their use can vary by location. Where you live might matter, so a call to your town's building department may help.
