Other Moisture Barriers Besides Kerdi for Shower
I have read most of the posts here on Kerdi and that definitely seems the way to go, but just wondering if it is something regional or fairly new. I was at a bathroom designer showroom where they had part of the shower removed so you could see the layers of their work. They used a bright orange kind of thick plastic sheeting for their moisture barrier.
I am planning on having tile people come in to give bids for redoing our Master floor and shower area and wanted to know what other types of material are used to help keep moisture from going through tile. We will have a tile shower floor instead of the acrylic shower pan. It will be enlarged to about 45 to 48" square.
I guess I have a few questions:
1. What are the layers or steps that should be done to have a good shower construction/install?
2. Green board vs cement board vs other options in the shower? I've heard of something called Denshield. Is this something to consider?
3. What are some of the other types of moisture barrier besides Kerdi that may be used that would be effective?
4. What are some things to definitely avoid in an shower tile install?
With your help I can do some additional research so I will know the questions to ask the installer to make sure their process will get me the best outcome. Anything else you might suggest I know would be appreciated.
