Step-by-Step Guide: How to Build a Shower Pan on a Concrete Floor

Before diving into the process, gather all the necessary materials and tools:

Step 1: Prepare the Concrete Floor

Start by cleaning the concrete floor thoroughly, removing any debris, dust, or loose particles. Use a masonry brush to scrub the surface and ensure it is free from any contaminants.

Step 2: Install the Waterproof Membrane

Apply a layer of waterproof membrane over the entire concrete floor, ensuring full coverage. This membrane will act as a barrier, preventing water from seeping through the shower pan.

Step 3: Create the Mortar Bed

Mix sand, cement, and water to create a mortar bed. Spread this mixture evenly over the waterproof membrane, using a trowel. Ensure the thickness of the mortar bed is consistent, typically around 2 inches.

Step 4: Add a Layer of Gravel

Place a layer of gravel on top of the mortar bed to enhance drainage. This layer allows any water that penetrates the floor tiles to flow away efficiently.

Step 5: Level and Compact the Gravel

Use a level to ensure the gravel layer is evenly distributed. Compact the gravel by tamping it down firmly, ensuring stability and preventing any shifting.

Step 6: Install the Shower Pan

Place the pre-fabricated shower pan onto the compacted gravel, ensuring it fits snugly. Follow the manufacturer’s instructions for optimal installation.

Step 7: Apply Tile and Grout

Once the shower pan is securely in place, proceed with tiling the shower floor. Apply the tiles using a suitable adhesive, leaving space for grouting. After the adhesive is dry, apply the grout, wiping away any excess.
