The shower stall walls are
The shower stall walls are framed with 2×4 studding and faced with some type of backerboard underlayment designed for receiving ceramic tile.
The installation of a shower pan starts with the spreading of a layer of mortar. The mortar needs to be sloped properly to enable water to run off towards the drain. The flexible plastic shower pan membrane liner is then installed on top of the sloped mortar bed.
The shower pan membrane liner should be cut to size and hand molded into the shower base.
Note: The shower pan should be cut to size such that several extra inches of shower pan material can be run up the shower stall side walls to enable the shower pan to be secured with nails to the studs.
