Final answer:
Shower pan linings can be constructed with cement mortar, rubber membrane, or PVC liner. Each provides a waterproof and durable base for a shower area.
Step-by-step explanation:
Shower pan linings can be constructed using a variety of materials to ensure they are waterproof and durable. The materials you can use include: 1) Cement mortar, which is a traditional method that involves creating a sloped base with a mixture of cement and sand; 2) Rubber membrane, a flexible sheet that can be laid down to create a watertight barrier; and 3) PVC liner, a plastic sheeting that serves the same purpose as the rubber membrane. All of the above options are viable materials for constructing a shower pan lining.
