Dry Fit, Level, and Mark — Set the Pan in Mortar

How to Install and Level a Shower Pan Base · Step 5 of 9
In this video
Perform a final dry fit of the shower pan. Place the pan in the alcove and use a level to ensure it is level in all directions. If it's not level, use shims to adjust it. While the pan is in place, mark the height of the top flange on each wall stud with a pencil. This creates a crucial reference line for when you set the pan in the mortar. Also, determine the final height needed for the PVC drain pipe. For this Oatey drain, the pipe should extend about 1/8 inch above the top of the caulking gasket when it's seated in the drain. Mark the pipe, remove the pan, and cut the pipe to the correct height using a hacksaw.

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.
