How to Install and Level a Shower Pan Base · Step 3 of 9
In this video
Assess the installation area to confirm the need for an offset drain. In this case, a floor joist is directly underneath the shower pan's drain opening, preventing a straight drain installation. Perform a dry fit by placing the drain body into the hole in the subfloor to confirm it correctly bypasses the joist and aligns with the shower pan.
Goal: Confirm Drain Fit
- Always dry-fit components to anticipate and solve alignment issues before applying permanent sealants or glues.

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.
