How to Build a Shower Pan on a Cement Floor

Building a shower pan on a cement floor is a relatively simple process that can be completed in a few hours. However, it is important to follow the steps carefully to ensure a watertight seal. Here are the essential aspects of building a shower pan on a cement floor:

Materials

To build a shower pan, you will need the following materials:

Cement backer board
Shower drain
Fiberglass mesh tape
Thinset mortar
Tile adhesive

Tools

You will also need the following tools:

Notched trowel
Mud pan
Drywall saw
Measuring tape
Pencil
Utility knife
Caulk gun

Steps

1. Prepare the Cement Floor

The first step is to prepare the cement floor by cleaning it thoroughly and removing any dust or debris. You should also make sure that the floor is level and free of any cracks or holes.

2. Install the Cement Backer Board

The next step is to install the cement backer board. This will provide a stable surface for the shower pan. Cut the cement backer board to fit the size of your shower and then secure it to the floor using mortar mix.

3. Apply the Waterproofing Membrane

Once the cement backer board is installed, you need to apply a waterproofing membrane. This will help to prevent water from leaking through the shower pan. Cut the waterproofing membrane to fit the size of your shower and then apply it to the cement backer board using thinset mortar.

4. Install the Shower Drain

The next step is to install the shower drain. Place the drain in the center of the shower and then secure it to the cement backer board using thinset mortar.

5. Tape the Joints

Once the shower drain is installed, you need to tape the joints between the cement backer board and the waterproofing membrane. This will help to create a watertight seal. Use fiberglass mesh tape and thinset mortar to tape the joints.

6. Tile the Shower Pan

The final step is to tile the shower pan. Apply tile adhesive to the waterproofing membrane and then press the tiles into place. Use spacers to ensure that the tiles are evenly spaced. Once the tiles are in place, you can grout the joints using sanded grout.

7. Seal the Shower Pan

Once the grout is dry, you need to seal the shower pan. This will help to prevent water from leaking through the pan. Apply a silicone sealant to the joints between the tiles and the walls and then smooth it out with a damp sponge.

Conclusion

Building a shower pan on a cement floor is a simple process that can be completed in a few hours. By following the steps in this article, you can ensure a watertight seal that will protect your bathroom from water damage.
