My understanding is that when tiling a shower wall, the standard preparation process includes:

  1. Install a vapor barrier
  2. Install cement backer board
  3. Apply a waterproof membrane

(This comes from https://www.lowes.com/n/how-to/prep-shower-wall-tile)

Is an acceptable alternative to do the following?

  1. Not use a vapor barrier
  2. For the walls, use DensGlass instead of backerboard; only apply backerboard at the shower pan and about 1.5 feet up from the floor
  3. Coat the walls with Red Guard; use a waterproof membrane at the bottom of the shower pan.
