Why is backer board necessary?
Backer board is a substrate material for tile. Unlike plywood and other wood substrates that can warp, backer board is hard and flat, so it won't buckle. Its stability allows you to adhere tile using a thinset mortar, making it relatively easy to create a tile surface that's level and consistent.
