Laying a shower pan is a crucial step in creating a waterproof and functional shower space. Whether you’re tackling a bathroom remodel or building a new one, setting the shower pan correctly ensures a durable and leak-free shower for years to come. This guide will provide you with comprehensive instructions on how to set a shower pan, empowering you to complete this task with confidence and precision.
Before embarking on the installation process, it’s essential to gather the necessary tools and materials. You’ll need a level, tape measure, utility knife, caulk gun, and caulk. Additionally, a drain flange and shower pan liner are required. Once your materials are assembled, you can begin the preparation phase, which involves cleaning the subfloor and ensuring it’s level. Properly preparing the subfloor creates a solid foundation for the shower pan, ensuring its stability and longevity.
With the subfloor prepared, you can proceed to set the shower pan. First, position the shower pan in its intended location and secure it with screws or nails. Ensure that the drain flange aligns perfectly with the drainpipe. Next, apply a generous bead of caulk around the base of the shower pan, where it meets the subfloor. Smooth out the caulk to create a watertight seal. Finally, install the shower pan liner, ensuring that it extends over the edges of the shower pan and overlaps the drain flange. This liner provides an additional layer of protection against water damage, ensuring a long-lasting and leak-free shower.
Installing the Flange Drain
Installing the flange drain is a critical step in setting a shower pan. Follow these detailed instructions to ensure a proper and leak-free connection.
Step 1: Clean the Drain Opening
Use a cleaning solution to thoroughly clean the drain opening in the subfloor.
Step 2: Apply a Bead of Silicone Caulk
Apply a generous bead of pure silicone caulk around the perimeter of the drain opening, both inside and outside the flange. Smooth out the caulk with your finger to create an even seal.
Step 3: Insert the Flange Drain
Align the flange drain with the drain opening and carefully insert it into place. Ensure that the flange is centered and flush with the subfloor.
Step 4: Tighten the Bolts
Secure the flange drain by hand-tightening the bolts that hold it in place. Use a screwdriver or wrench to further tighten the bolts, but do not overtighten to avoid damaging the flange.
Step 5: Remove Excess Caulk
Use a utility knife or sharp object to remove any excess caulk that may have squeezed out from under the flange.
Step 6: Install the Drain Cover
Finally, install the drain cover over the flange drain to complete the installation.

Leveling and Sloping the Pan
To ensure proper drainage and prevent water damage, the shower pan must be leveled and sloped properly.
Materials:
- Level
- Marking pen
- Screwdriver
- Shims (if necessary)
Procedure:
- Inspect the pan: Examine the shower pan for any damage or imperfections.
- Find the high and low points: Place a level on the pan and adjust it until the bubble is centered. Mark the high point and the lowest point.
- Determine the slope: The slope for a shower pan should be 1/4 inch per foot. Measure the distance between the high point and the lowest point and multiply by 1/4. This will give you the amount of elevation difference that needs to be created.
- Install shims: If necessary, use shims to raise the pan at the low points to create the desired slope.
- Secure the pan: Once the pan is level and sloped, use the included screws or fasteners to secure it to the subfloor.
- Check the slope: Re-check the slope of the pan using a level. Adjust the shims or screws as needed until the bubble is centered and the slope is even.
Tips:
- Use a large level for greater accuracy.
- Double-check the slope in both directions (front-to-back and side-to-side).
- If the pan is not properly sloped, water can accumulate and cause leaks or other issues.
How to Set a Shower Pan
Setting a shower pan is a relatively simple task that can be completed in a few hours. By following these steps, you can ensure that your shower pan is properly installed and will provide years of trouble-free use.
- Prepare the subfloor. The subfloor should be level and smooth. If there are any uneven areas, they should be leveled with a self-leveling compound.
- Install the shower pan. Place the shower pan in the desired location and make sure that it is level. Once the shower pan is level, use a caulk gun to apply a bead of caulk around the perimeter of the pan.
- Secure the shower pan. Use screws to secure the shower pan to the subfloor. The screws should be spaced evenly around the perimeter of the pan.
- Install the drain. The drain should be installed according to the manufacturer’s instructions. Once the drain is installed, use a caulk gun to apply a bead of caulk around the perimeter of the drain.
- Test the shower pan. Once the shower pan is installed, turn on the water and let it run for a few minutes. Check for any leaks around the perimeter of the pan or around the drain.
