You want to use only one water containment method in your shower, Ryan. Either the properly installed moisture barrier behind the wallboard, or a direct bonded waterproofing membrane on the face of the wallboard, but not both.

With your niche(s), you'll not likely be able to effectively use the moisture barrier behind the wallboards. If you cut the moisture barrier around your niche, you'll need to use the waterproofing membrane in that area anyway, so better to use that method for the entire shower.

My opinion; worth price charged.
