Place the support flange over the installed pipe nipple so it sits flush against the wall. Use the flange itself as a template to mark the positions for the four mounting screws with a pencil. Remove the flange, and use a power drill to create pilot holes at each of the four marked locations. Insert the provided wall anchors into the drilled holes until they are flush with the wall surface. Finally, reposition the support flange over the anchors and use a screwdriver to drive the mounting screws in, securing the flange tightly to the wall.
Goal: Securely attach the mounting flange to the wall
- Use a level to make sure the flange is perfectly straight before marking the holes. This ensures the faucet will be level.
- Select the correct drill bit size for your wall type and the provided wall anchors to ensure a secure fit.

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.
