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

How to Install and Level a Shower Pan Base · Step 6 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.
Goal: Confirm level fit and determine drain pipe height

FAQs
How difficult is it to install a shower pan for a DIYer, and what's the realistic time commitment?
This is an intermediate project, requiring precision and patience, especially with leveling and mortar work. While the estimated time is 16 hours, allow extra time for potential subfloor repairs or unexpected issues. Rushing can lead to costly mistakes, so take your time and don't skip steps.
Why is a mortar bed crucial for a new acrylic/fiberglass shower pan, and which type should I use?
A mortar bed provides essential solid support beneath the shower pan, preventing flex, squeaks, and potential cracking over time. It also allows you to precisely level the pan for proper drainage. The project specifically calls for Type S mortar, such as Greencore or Quikrete mortar mix.
What are the most critical steps to ensure my shower pan is perfectly level and drains correctly?
Accurate leveling begins with a solid, level subfloor. Dry-fit the pan multiple times, marking its position and checking it with a long level in all directions. When setting the pan into the mortar, continuously check for level and adjust the mortar bed as needed before the mortar begins to set.
What precautions should I take to prevent leaks around the drain assembly and where the pan meets the wall?
Ensure the drain fitting is properly installed and sealed according to its manufacturer's instructions, using plumber's putty or silicone caulk as recommended. Secure the pan's flanges to the wall studs precisely, and apply a waterproof sealant where the pan meets the wall before installing wall coverings to prevent moisture intrusion.
