Like look says, fine on the vertical surfaces, but not kosher on flat surfaces where you know water will be behind the finished surface. When you install shower pan liners, you never put nail holes in the curb or bottom. You nail the pan liner on the studs 6+" inches up and then lap your vapor barrier over the pan liner. Water then sheds down your tile walls and into your pan. If water gets behind your floor tile, as it inevitably will, the pan liner catches the water and sheds it to the weep holes. Now, since you have a fiberglass pan, you've eliminated the pan liner and mortar bed, but you still have to make sure the water gets to your pan. The shelf you made
may prohibit that.
Am I way off base here, guys?
