What Is The Best System For Waterproofing A Shower Floor?

Back in the day, contractors used materials like copper or rubber and installed a liner beneath a shower floor to protect the foundation of the bathroom from absorbing too much moisture. While this method was relatively effective, it also had several flaws. For instance, the shower floor accumulated lots of humidity that pooled on the liner as time progressed. As a result, mold would grow, eventually damaging the shower. 

At present, contractors and homeowners are much more aware of the different ways that waterproofing can help save a shower floor and prevent it from growing mold or mildew over time. 

It is essential to note that there isn’t only one way to do it correctly when waterproofing a shower floor. The main ways of waterproofing a shower floor include liquid membranes, foam shower bases, foam wallboards, and sheet membranes. Please remember to keep your budget and the size of your bathroom in mind before picking a waterproofing system. As mentioned below, we would also like you to note that multiple systems work for waterproofing a shower floor.

Liquid membranes 

Liquid membranes are one of the most accessible waterproofing membranes to use. To put it simply, applying a liquid waterproofing membrane involves painting the floor and walls of your shower with a waterproof liquid. You apply it with a paint roller. Once the layer is dry, it acts as an elastomeric layer, which remains flexible. It offers users a quick and straightforward solution to waterproof their showers. 

Foam shower bases 

Installing a foam shower base is a much longer process and requires more effort than installing a liquid membrane. You install it by placing it on your shower floor before adding the regular shower base. Many foam shower bases are sold with waterproof shower curbs. They help provide structural support.

Foam wallboards 

Foam wallboards are similar to foam shower bases. The only difference is installing them below the shower floor and wall tiles. Like the foam shower bases, they provide you with structural support and serve as a waterproofing membrane. 

Sheet membranes 

The last system for installing a waterproofing membrane on a shower floor uses a sheet membrane. These membranes are easy to install because all you need to do is peel them from their packaging and stick them on the shower floor. 

Benefits Of Using Waterproofing Membrane

Buying Guide: What to look for in a waterproofing membrane for a shower?

When buying a waterproofing membrane for your shower, there are several factors that you need to keep in mind. It can be easy to go out and buy the first waterproofing membrane product you see, but please keep in mind that the product you purchase might not work well for your shower. Thankfully, we’ve put together a brief guide that will help you figure out what to look for in a waterproofing membrane. 

Where are you going to apply the membrane? 

The answer to this question depends on what your shower situation is. For example, if your house is a new construction or in the process of being renovated, you might want to waterproof your shower before laying the tiles and adding bathroom fixtures. This means that you are waterproofing the negative side or interior side of your shower. If you are updating your shower, you will be applying the waterproofing membrane on the positive side of the shower or the side that you can see. 

The negative side will require waterproofing membranes made of materials like epoxy, while the positive side needs to be waterproofed with materials like rubber. 

Cost of the project 

Once you’ve figured out where to apply the waterproofing membrane in your shower, you need to factor in your budget. The list of products mentioned above contains high and low-end waterproofing membranes that come in fabric tape and liquid membranes. 


What is the best way to waterproof a shower?

The best way to waterproof a shower is to apply two layers of a liquid membrane and let it dry completely before using your shower.

How do you apply a waterproof membrane to a shower?

If you are using a liquid membrane, use a paint roller to apply two coats to the walls and floor of your shower. If you are using foam wallboards and a foam shower base, apply a layer of a liquid waterproofing membrane, then use it to stick the foam wallboards and shower base. 

How long does the waterproofing membrane take to dry?

It takes anywhere from one to three days to dry. 

Do you need a waterproof membrane on a cement board?

Yes, you do.
