Pouring Shower Pan On Concrete Slab: My Personal Experience

When I was renovating my bathroom, I decided to install a new shower. However, I was hesitant about pouring the shower pan on the concrete slab. I had never done it before and was worried about making mistakes. After doing some research and seeking advice from professionals, I decided to take the plunge. Here is what I learned about pouring a shower pan on a concrete slab.

Step-by-Step Guide for Pouring Shower Pan On Concrete Slab

Step 1: Prepare the Concrete Slab

Ensure that the concrete slab is clean and free from debris. If there are any cracks, repair them before you begin. If the slab is not level, use a self-leveling compound to level it out.

Step 2: Install Drain

Install the drain in the center of the shower floor. The drain should be flush with the surface of the concrete slab. Use a waterproof sealant to seal around the drain.

Step 3: Build a Dam

Build a dam around the perimeter of the shower using a waterproof material such as silicone caulk or roofing tar. The dam should be approximately 2 inches high and should be level with the top of the drain.

Step 4: Mix and Pour Mortar

Mix the mortar according to the manufacturer’s instructions. Pour the mortar into the shower area and use a trowel to spread it evenly. The mortar should be approximately 2 inches thick.

Step 5: Shape the Mortar

Shape the mortar around the drain, ensuring that it slopes toward the drain. Smooth out any rough edges using a trowel. Allow the mortar to dry completely.

Step 6: Waterproof the Shower Pan

Apply a waterproof membrane over the mortar. The membrane should extend up the walls of the shower and over the dam. Seal any seams or joints with waterproof tape or sealant.

Step 7: Install Tiles

Once the waterproof membrane has dried, you can install the tiles. Use a waterproof adhesive to attach the tiles to the shower pan. Allow the adhesive to dry completely before grouting.

Question and Answer

Q: Can I pour a shower pan on a wooden subfloor?

A: No, it is not recommended to pour a shower pan on a wooden subfloor. Wood can absorb water and rot over time, which can lead to leaks and other problems. It is best to install a concrete backer board over the wooden subfloor before pouring the shower pan.

FAQs

Q: How long does it take for the mortar to dry?

A: The drying time for mortar can vary depending on the humidity and temperature. It is best to follow the manufacturer’s instructions for drying times. Typically, it can take anywhere from 24 to 72 hours for the mortar to dry completely.

Q: Can I install a shower liner instead of pouring a shower pan?

A: Yes, you can install a shower liner instead of pouring a shower pan. A shower liner is a waterproof membrane that is installed over the subfloor and up the walls of the shower. It is an easier and quicker solution than pouring a shower pan, but it may not be as durable in the long run.
