I will be creating a built in shower in my home, in place of the plastic bathtub. I continue to get conflicting information and still have other unanswered questions, so bare with me.
First, how high up do I need to water proof the walls? All the way to the ceiling? What about the ceiling?
Second, if using Kerdi I can apply it over dry wall, however, it seems to be expensive. If I do go this route, what do I used to seal the floor, and cover the seams? Ive heard some seam sealing stuff will not allow thin set to adhere well.
Third, Kerdi is expensive and Id almost rather use redgaurd or a similar liquid membrane, and although it says it can be applied to drywall, most do not recommend it. Id agree, better safe than sorry. So my question is, even though the plastic barrier mounted to my wall is there to protect the wall from water, wouldnt the wall be cement board any ways?
3a, If it is cement board, do I need to prime it or just apply redgaurd right to it? Ive heard not to apply redguard to painted cement board, can I sand the paint off if painted?
4- If using redgaurd would I apply it to the cement floor or the ply wood under the cement?
5- if using Kerdi, would I apply it to the cement floor or under the cement floor, or do it the old way and do a cement floor, liner, and more cement?
6- if behind the plastic tub barrier there is drywall and not cement board, I will likely replace the drywall and not put CB over it. Do I need a liner behind the CB? What kind? 6a- Do I need to replace the drywall all the way to the ceiling? The plastic tub liner only goes about 6 feet up the wall from the ground.
