Installing a Shower Pan

 
 

Installing a shower pan is a project most homeowners who have some experience working with plumbing and basic tools can do themselves. The most critical elements of your project are getting the drain positioned properly in the slab and positioning the shower base correctly over the drain. Select your shower base then have the drain roughed in to meet its dimensions. If you’re not experienced in installing a drain in a slab, consider having a professional take care of this part of your project.

 

If you are installing a shower pan as part of a remodeling project, the floor needs to be properly prepped and leveled before the pan is installed. While the steps for installing the base are the same for both new construction and remodels, this project assumes the floor has been properly prepped and leveled. It also assumes framing is in place to which the shower pan can be secured.

Step 1: Test-Fit the Shower Pan

2. Test-fit the shower pan to confirm the pan’s drain opening fits over the drain in the
     floor.
  

Step 2: Attach the Flange to the Drain Pipe

Step 2: Attach the Flange to the Drain Pipe 1. Test-fit to make sure the drain flange, or outer lip, will be flush with the surface of
    the shower base. If necessary, add an extension.

2. Apply primer and cement to the flange and drain pipe and attach them to the drain
    pipe in the floor.

3. Allow the cement to dry according to the manufacturer’s instructions.
  

Step 3: Attach the Gaskets and Set the Base

Step 3: Attach the Gaskets and Set the Base 1. Place the gaskets on the drain flange so they sit between the flange and the
    bottom of the shower pan.

2. Set the base in place over the drain.
  

Step 4: Caulk and Seat the Drain Body

Step 4: Caulk and Seat the Drain Body 1. Caulk the drain flange with silicone.

2. Line up the holes in the drain body with the screw holes in the flange body.

3. Press the drain body firmly into place and attach the drain screen with the screws
    that came with the assembly.
  

Step 5: Pre-drill Holes Through the Shower Base Rim

Step 5: Pre-drill Holes Through the Shower Base Rim 1. Check the rim of the base to be sure it’s perfectly level.

2. Mark the center of each wall stud on the rim.

3. Pre-drill a hole through the rim at each mark.

4. Nail the pan to the wall stud with rustproof galvanized nails. Shim as necessary to
    keep the shower base square.

5. Now that your shower base is installed, the next step in your project is to install the
    walls for your shower. Our project guides for installing shower walls direct-to-stud
