How To Build A Tile Shower Pan On Concrete: A Comprehensive Guide

A well-constructed tile shower pan on concrete is the key to a durable and functional shower system. Building one requires careful planning, preparation, and execution. Here's a step-by-step guide to help you achieve a professional-looking tile shower pan on a concrete base:

Materials Required:

Portland cement
Sand
Mortar mix
Lath or wire mesh
Screeds
Drain
Tile
Grout
Sealant

Step-by-Step Instructions:

1. Prepare the Concrete Base:

Ensure the concrete base is level, smooth, and clean. Remove any debris or imperfections that may interfere with the bonding process.

2. Install the Drain:

Place the drain in the desired location and secure it according to the manufacturer's instructions. The drain should have a weep hole to allow water to escape.

3. Create a Mortar Bed:

Mix a mortar bed using Portland cement, sand, and water. Spread the mortar bed over the concrete base, creating a layer about 1-2 inches thick. Use a screed to level the surface.

4. Install the Lath or Wire Mesh:

Lay lath or wire mesh over the mortar bed to reinforce it. The mesh should overlap the edges of the pan by at least 6 inches.

5. Form the Pan Slope:

Use additional mortar to create a slope towards the drain. The slope should be at least ¼ inch per foot to ensure proper water drainage.

6. Cure the Pan:

Allow the mortar pan to cure for at least 24 hours before proceeding with tiling.

7. Install the Tile:

Once the pan is cured, apply mortar to the back of each tile and press it into place. Use spacers to ensure even spacing between the tiles.

8. Grout the Tiles:

After the tiles are set, apply grout to the joints between them. Use a grout float to press the grout into the joints and remove excess.

9. Seal the Pan:

Apply a waterproof sealant to the joints between the tiles and around the drain to prevent water penetration.

Tips for Success:

Use high-quality materials designed for wet areas.
Ensure the mortar bed is properly mixed and leveled.
Allow adequate time for curing before using the shower.
Seal the pan regularly to maintain its integrity.

By following these steps, you can build a durable and watertight tile shower pan on concrete that will enhance the functionality and aesthetics of your bathroom for years to come.
