Acrylic: While shower pans made from acrylic are typically reinforced with other materials, they are largely made of large sheets of acrylic that have been heated and stretched onto a mold.

Do you need a shower pan liner on concrete floor?

It will need to be lined or it will wick into the slab and studding. The liner also makes the walls around the pan water-tight, that’s why the liner normally goes up at least 3″ above the pan behind the tile and backer material. Moisture gets behind the wall tile and is eventually caught by the liner.

How thin can a mortar shower pan be?

Thin-set mortars are typically about 3/16”, which makes it preferred when height is an issue (e.g. barrier free showers). When tile is bonded to the subfloor with a thin-set, movement in the subfloor can telegraph through the tile and cause it to crack.

How far up the wall should a shower pan liner go?

The pan liner should finish a minimum of 6 inches above the framed or (roughed-in) curb height. This height allows for the application of concrete base and finishes to be applied.
