The Tools and Materials You Will Need

Assuming you will be starting from scratch, these are the tools and materials you will need to build a walk in shower pan:

-Shower base pan
-PVC liner
-Notched trowel

To start, you will need a shower base pan. This can be made of cast iron, acrylic, fiberglass, or tile. You will also need a PVC liner to protect the base pan from water damage. Tile is the most common material used for walk in showers, as it is waterproof and durable. Grout is used to fill in the spaces between tiles, and caulk is used to seal the edges of the shower. Sealant is applied over the grout and caulk to create a watertight barrier. A trowel is used to apply the grout and caulk, and a sponge is used to clean up any excess material. Finally, a notched trowel is used to spread tile adhesive onto the surface before laying down the tile.

Step by Step Instructions

Assuming you have a basic understanding of framing, building a walk in shower pan is not a difficult task. With a few tools and some careful measuring, anyone can do it. Here are the steps:

1. Cut out the shower base. Using a saw, cut out the bottom piece of plywood that will form the base of the shower pan. The base should be large enough to accommodate the drain and give you at least a few inches of space on all sides.

2. Install the drain. Fit the drain into the hole in the center of the base and secure it with screws or bolts. Make sure the drain is level before moving on.

3. Attach walls to the base. Cut pieces of plywood to serve as walls for your shower pan and screw them into place around the perimeter of the base. Be sure to leave an opening for the door or shower head.

4. Finish up by adding tile or another waterproof material to cover all surfaces inside the shower pan. This will help keep water from seeping through and causing damage to your home over time.

Adding the Finishing Touches

After all of the tiling is complete, you can add the finishing touches to your walk in shower pan. Start by adding caulk around the perimeter of the shower base. Then, add trim pieces around the shower base, if desired. Finally, install a shower door or shower curtain.


Building a walk in shower pan is not as difficult as it may seem. With the right steps and materials, you can easily create a stunning walk in shower pan that will be the envy of your neighborhood. Use our tips to help you get started on building your own walk in shower pan today.
