Ensure the floor and the bottom of the pan are clean and free of dust and debris. Apply a polyurethane sealant, such as XtraBond 9500, to the underside of the pan in the channels and in a wavy pattern across the flat surface. Also apply a bead around the drain fitting. Now, apply PVC cement to the inside of the installed drain fitting and the outside of the floor pipe. Carefully lower the pan into position, aligning it with your floor marks and the drain pipe. Step into the pan and wiggle it to spread the sealant and ensure a strong bond with the subfloor.
Goal: Adhere the washer pan to the subfloor and connect the drain

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.
