Once all PVC parts are cut to the correct lengths, prepare them for solvent welding. Use a deburring tool to remove any rough edges from the inside and outside of the pipe cuts. Lay the parts out on newspaper. Wearing gloves, apply a coat of purple PVC primer to the outside of the pipe end and the inside of the fitting it will connect to. The primer cleans and softens the PVC for a better weld. Then, apply a generous layer of PVC cement over the primed areas. Immediately join the pipe and fitting with a firm push and a quarter-turn twist. Hold the joint together for at least 30 seconds. Repeat for all joints to create the full replacement assembly.
Goal: Solvent weld the new PVC pipe assembly
- PVC primer and cement fumes are strong. Work in a well-ventilated area.
- Make alignment marks on your pipes and fittings during the dry-fit stage to ensure they are correctly oriented when you glue them together quickly.

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.
