How to water proof your tile shower install

[Jay H.]

When I am installing a new shower, I always use peel and stick tar tape and 6mill plastic visqueen. 

1st peel and stick the tar tape to the studs and stick to the top 1" lip of the base and staple to the studs.

2nd overlay the visqueen on top of the tar tape and staple to the studs

3rd properly attach your hardy board over the visqueen.

Jay the way you are doing it is not waterproofing your surround,thats more of a vapor barrier. To properly waterproof it needs to be between tile and wall such as the membrane that is mentioned or i prefer a product by schluter. Just so you know for the future, the hardi board or durarock boards are NOT waterproof, more like water resistant. Grout,tile and backer boards are not waterproof, you need to use something between the two.
