Before applying any adhesives, perform a dry fit. Clean the inside of the pipe and the surrounding area. First, apply PVC cleaner, then PVC primer, and finally heavy-duty PVC cement to the outside of the pipe and the inside of the drain fitting. Firmly press the drain into place with a slight twisting motion. Immediately use a level to ensure the drain flange is perfectly level in all directions. Use shims under the flange if necessary to hold it in the correct position while the cement cures.

Goal: Install Drain

  • After setting the drain, you can apply another coat of cement around the inside seam for an extra-strong seal.

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.
