Want to know how to waterproof a shower?

Remodeling or updating your bathroom is an expensive endeavor. Most people look for ways to budget their remodeling costs to prevent themselves from spending too much on the project. This often works out for the best and leaves the owners with the perfect bathroom for their budget.

However, certain things can go wrong. The worst that can happen is your shower will leak. This will ruin the time you spent on the remodel, and it’ll also ruin your budget.

This makes waterproofing your shower an important part of any bathroom remodeling project. Read what’s below to know how to make sure your shower is waterproof. Follow these steps to prevent leaks in your shower!

1. Make Sure You Measure Your Showering Area

Before you start with anything, always remember to measure your showering area twice. Doing so ensures that you won’t end up with a major disaster. Measure again if your results aren’t the same 2 times in a row.

This method of measuring ensures that you won’t run short of materials. The primary cause of leaks is not having enough material to cover your entire shower. Knowing how much you need to cover the entire shower is the best way you can prevent water damage in your bathroom.

Doing this also helps you plan the budget of your waterproofing project. You can then use this as a basis for how much you’ll be spending.

2. Add a Layer of Reinforcing Membrane on the Wall

This is an optional step, but it’s one that can ensure total waterproofing in your shower. Reinforcing membranes are 100% water-resistant. Adding a layer of reinforcing membrane before anything else helps you keep your foundation strong in the bathroom.

Regardless of whether your shower’s walls are cement or wood, you want to keep the water away from them. Both materials can weaken once they get in contact with water. Once they erode, it makes it easier for the shower to form a passage for a leak.

Adding this extra layer of reinforcing membrane before anything else will help prevent it from wearing down.

3. Install a Cement Board

Your next step is to install a cement board along the walls. As mentioned above, cement is still susceptible to water damage. It can resist water longer than wood can though.

Doing this is another way for you to decrease the likelihood of a leak happening in your bathroom. It means that you’ll have a slight decrease in the space though. It’s a small price to pay to protect the rest of your bathroom from water damage.

The cement board also serves as a medium for the next steps. It becomes a place for the next items to have a firm hold in the bathroom.

4. Apply a Coat of Liquid Waterproofing

The next step is to apply a coat of liquid waterproofing to the cement board. It makes the board even more resistant to water, ensuring its longevity.

Use a high-quality brush or roller when you’re applying the waterproofing liquid. Liquid waterproofing is thick and heavy, and it must stay on your brush to be effective. Having a low-quality brush means that it won’t be able to carry as much liquid as you want it to.

This can cause uneven patches of liquid waterproofing on your cement board. Make sure you form a thick and even coat to prevent the waterproofing material from cracking.

5. Cover With Another Layer of Reinforcing Membrane

Before the liquid dries, consider adding another layer of reinforcing membrane to the wall. This will make it even harder for water to penetrate and reach the cement. You must then fasten it in place.

Do this from the top going down. This ensures that you don’t have any pockets of air between the membrane and liquid. These pockets can be areas where moisture can accumulate

Moisture can destroy your waterproofing sooner than you expect. Use anything flat to press on the reinforcing membrane and force the air out.

After that, apply another layer of waterproofing liquid for good measure. Make sure this covers the corners and edges of the shower. Make sure that the waterproofing dries before you proceed to the next step.

6. Install the Floor Tray

Once the waterproofing liquid dries, make sure the shower floor is even. Use a spirit level to determine if the floor isn’t bumpy. Having an even floor makes it easier to install your floor tray and harder for pockets of moisture to form.

Mark the area of your drain beforehand to make it easier for you to cut a hole through the floor tray. You should also line the edges and corners with waterproof material. This makes sure water doesn’t reach the foundation of the shower.

7. Add Another Layer of Reinforcing Membrane

Knowing how to waterproof a shower means you’ll use a lot of reinforcing membrane. Do this for the floor too, but only after you apply another coat of liquid waterproofing to the floor tray. Make sure you use the same brush as with the walls to apply a thick, even coat.

The last thing you must do is apply the reinforcing membrane. It’s okay to trim away any excess material if it’s too big for the floor. What’s important is that you cover the entire floor with a reinforcing membrane.

Fasten the membrane the same way you did with the walls. Now, all that’s left is to install the tiles you chose. Remember to make sure the materials dried up before you do this.

After tile installation, consider running a flood test to see if there’s an area that allows water to seep through. Keep an eye out for any bubbles when doing this. If no bubbles appear, then the shower is ready for you to use.
