Dry Fit and Level with Shims — Set the Shower Pan

How to Install and Level a Shower Pan Base · Step 5 of 8
In this video
To ensure the shower pan is perfectly level, perform another dry fit. Place the pan in the shower stall. Use a long level across the top edges of the pan in both directions (front-to-back and side-to-side). The floor is uneven, so small wooden shims are inserted under the pan's base until the pan is perfectly level. Once level, use a pencil to trace the outline of the pan's flange onto the wall studs. This line will act as a guide for setting the pan into the mortar at the correct height.
Goal: Determine the level position of the pan and mark the studs
- A perfectly level pan is crucial for proper drainage and to prevent water from pooling.

FAQs
Before installing the shower pan, how thoroughly do I need to prepare my subfloor, and what should I look out for?
Ensure the subfloor is clean, dry, and structurally sound. Check for rot, water damage, or uneven spots, repairing them as needed to provide a stable foundation for the mortar bed. A smooth, level subfloor is crucial for the pan's stability and proper drainage.
What's the right consistency for the mortar bed, and how much do I need to mix for a standard shower pan?
The mortar (like SAKRETE 80 lb. Gray Type S Mortar Mix) should be mixed to a thick, peanut butter-like consistency, allowing it to hold its shape without being too wet or crumbly. For a typical 48x32 inch pan, one 80lb bag should be sufficient, but always check the pan manufacturer's recommendations. Ensure even coverage to fully support the pan.
Beyond just using a level, what are the key steps to ensure my shower pan is perfectly level and stable?
Dry-fit the pan multiple times, checking with a long level in all directions (front-to-back and side-to-side). Once in the mortar, apply even pressure and re-check constantly, making micro-adjustments by lightly tapping high spots or adding mortar to low spots if necessary. Ensure the pan has full, even contact with the mortar for stability and proper drainage towards the drain.
What are the critical steps for correctly installing and sealing the drain assembly to prevent leaks?
Apply a generous bead of plumber's putty (like Oatey 9 oz. Stain-Free Plumber's Putty) around the drain flange before seating it firmly into the pan opening. Hand-tighten the nuts from underneath first, then use Channellock pliers for a final snug turn, being careful not to overtighten and crack the pan. Always perform a water test for leaks before proceeding.
