Do you need a shower pan liner on a concrete floor?

A shower pan liner is installed on top of a concrete floor. It’s important to use the right adhesive for your particular shower pan liner. CPE and PVC liners require different types of adhesives, and you need to make sure you select the right type of adhesive for your concrete floor. In this article, we’ll discuss CPE and PVC liner adhesives and how to install them.

Before you start, make sure you’ve put down a layer of mortar on the concrete floor. Ideally, it’s about half an inch thick where the drain is. This will minimize moisture retention and allow you to install a shower pan liner over it. If you have a wood subfloor, use a sand/topping mix. These materials are easy to mix, and the instructions are simple to follow.

The next step is to lay a cement board backing on top of the concrete. The cement board backing is the substrate for the tiled walls. Make sure to apply a mortar bed about one and a quarter inches thick around the drain assembly. The mortar bed should slope one-fourth inch upward per foot away from the drain to allow for room for the actual tiles. If you do not install a shower pan liner, concrete may be an adequate base but is not recommended. Before you go ahead and install a shower pan liner, make sure you place a proper membrane between the concrete and any vulnerable materials.

Once you have laid the concrete base, you should apply a waterproof membrane over it. The best waterproofing solution for a shower base is Portland cement mixed with fine sand. You can also buy ready-to-use concrete products. If you want to mix your own concrete, make sure to measure the ingredients carefully and use a level to ensure you get a perfect mix.
