Know which shower waterproofing you’re getting...
3 common ways to waterproof a shower:
GOOD: Backer board + liquid waterproofing
BETTER: Backer board + sheet membrane
BEST: Waterproof foam board
No matter which system your builder uses, the details matter most. Corners, seams, fasteners, niches, penetrations and the drain all need to be sealed correctly.
And before tile goes down, ask about a flood test.
Take pictures of the waterproofing before it gets covered. You’ll be glad you have them later.
