Mortar Bed Shower Liners

A waterproof mortar bed shower liner prevents this from occurring, by stopping and directing the water to the shower drain.

A mortar bed shower liner, as the name implies, is constructed out of mortar. In addition, there is a flexible shower pan membrane liner that is sandwiched in between the mortar.

To be more specific a mortar bed shower liner is comprised of two layers of mortar. First a pre-slope mortar bed is installed such that it creates a gentle slope towards the shower drain. A flexible shower pan membrane liner is then installed on top of the pre-slope.

A final layer of mortar, known as the base layer, is then poured over the membrane liner to create the finished mortar bed shower liner. Ceramic tile can then be installed over the mortar. Installing a mortar bed shower liner can be a little tricky, however handy do-it-yourself homeowners can tackle this type of project with a little upfront knowledge. Creating the proper pre-slope requires a bit of math and art skills. In addition, folding and fastening the flexible shower pan into place can involve some origami skills. If done properly, however, a mortar bed shower liner works extremely well and will last indefinitely.

Mortar bed shower liners can also be designed for all shower stall shapes and sizes. They can even be constructed to support shower seats.

When it comes to selecting the type of flexible shower membrane liner material to use, you have basically two choices. Your first choice is a waterproof membrane liner that is constructed out of Chlorinated Polyethylene (CPE).

You can typically find either of these shower pan membrane liners at any home improvement store.

So if you are considering installing a ceramic tile shower, make sure to install a mortar bed shower liner first.

Without it, your ceramic tile shower will undoubtedly leak and cause water damage in your home.
