With the mortar bed spread, carefully lower the shower pan into place. Align the drain pipe with the drain assembly on the pan. Press down firmly and evenly across the entire surface of the pan to fully embed it in the mortar. Use the level lines you marked on the studs to ensure the pan is at the correct height. Use a level again on all sides to double-check that the pan is perfectly level. Once satisfied with the position, pre-drill pilot holes through the pan's mounting flange into the wall studs. Secure the pan by driving stainless steel lath screws through the flange into each stud.
Goal: Install the shower pan into the mortar and fasten it to the studs
- Pre-drilling holes in the flange helps prevent cracking when you drive the screws.
- Once the pan is set in the mortar, avoid moving it as this can disrupt the bond and create voids.

FAQs
What is the most critical step to ensure a leak-free shower pan installation?
The most critical steps involve a thorough dry fit to confirm proper drain alignment and a securely sealed drain connection. Ensure the pan is set in a complete and solid bed of mortar, and all plumbing connections are sealed with appropriate compounds for long-term integrity.
How important is it to perfectly level the shower pan, and what happens if it's not?
Perfect leveling is crucial for proper water drainage. If the pan isn't perfectly level, water will pool in low spots instead of flowing to the drain, leading to mold, mildew, and potential subfloor damage. Use a reliable level and check it from multiple angles during the dry fit and after setting the pan.
What type of mortar should I use for setting the shower pan, and how do I mix it?
Use Type S mortar, like the Greencore 65 lbs. Type S Mortar listed, as it offers superior strength and bonding. Mix it according to the manufacturer's instructions to achieve a thick, peanut-butter-like consistency that is workable but firm enough to hold the pan's position without slumping.
What safety precautions should I take when installing a shower pan, especially regarding dust and materials?
Always wear work gloves, safety glasses, and a dust mask (such as the Dyiom or Paitning mask mentioned) when mixing mortar, cleaning the subfloor, or cutting materials. Ensure your work area is well-ventilated to minimize inhaling dust and chemical fumes for your safety.
