How To Build A Shower Pan On A Concrete Floor

Building a shower pan on a concrete floor can be a challenging task, but with the right tools and knowledge, it is possible to do it yourself. In this article, we will share our personal experience and guide you through the steps of building a shower pan on a concrete floor.

Step by Step Guide

Step 1: Prepare the Concrete Floor

The first step is to prepare the concrete floor by cleaning and leveling it. Use a broom or vacuum to remove any debris or dust, and then level the floor using a self-leveling compound. This will ensure that the shower pan is even and stable.

Step 2: Create the Drain Hole

The next step is to create the drain hole. Determine the location of the drain and mark it on the concrete floor. Use a hole saw to cut the hole and remove any excess concrete.

Step 3: Install the Drain

Install the drain according to the manufacturer’s instructions. Apply plumber’s putty around the drain flange and insert it into the drain hole. Tighten the drain using a wrench and then connect the drain to the plumbing.

Step 4: Install the Pre-Slope

The pre-slope is a layer of mortar that is installed on top of the concrete floor. It is sloped towards the drain to ensure that water flows properly. Mix the mortar according to the manufacturer’s instructions and spread it evenly over the floor. Use a trowel to slope the mortar towards the drain.

Step 5: Install the Shower Liner

The shower liner is a waterproof barrier that is installed over the pre-slope. It prevents water from seeping through the mortar and damaging the concrete floor. Cut the liner to size and lay it over the pre-slope. Make sure that the liner covers the drain and extends up the walls.

Step 6: Install the Final Mortar Layer

The final mortar layer is installed on top of the shower liner. Mix the mortar according to the manufacturer’s instructions and spread it evenly over the liner. Use a trowel to slope the mortar towards the drain. Let the mortar dry for at least 24 hours before tiling.

Top 10 Tips and Ideas

• Use a pre-made shower pan if you are not confident in building one yourself.
• Make sure that the drain is properly installed and connected to the plumbing.
• Choose a waterproof shower liner that is durable and easy to install.
• Use a high-quality mortar that is designed for shower pans.
• Ensure that the pre-slope is properly sloped towards the drain.
• Seal any gaps or holes in the shower pan to prevent water from seeping through.
