How to Install and Level a Shower Pan Base · Step 7 of 7
In this video
First, dry-fit the shower pan and use a level to ensure it is perfectly level on all four sides, using shims if necessary. Next, install the drain assembly by applying plumber's putty to the drain flange and pipe dope to the underside, then tightening the gaskets and nut. Lay down paper on the subfloor, mix a batch of mortar, and spread it evenly. Carefully set the shower pan into the wet mortar, pressing down to ensure full contact and re-checking for level. Secure the pan's flanges to the studs with the provided clips and screws. Once the mortar has set, use an inside pipe cutter to trim the PVC drain pipe flush. Finally, install the rubber gasket, brass nut, and drain cover plate.
Goal: Install shower pan
- If the pan isn't level during the dry fit, use wood shims or a full shingle to raise the low side.
- Place paper on the subfloor before applying mortar to prevent it from falling through cracks in the floorboards.
- Wiggle the pan when setting it in mortar to ensure it makes good contact with both the mortar and any shims used for leveling.

FAQs
The project is listed as 'beginner' but has an estimated time of 12 hours. Is it truly suitable for someone new to DIY, and what makes it take so long?
While the individual steps are beginner-friendly, achieving a perfectly level and leak-proof shower pan requires patience and meticulous attention to detail. The 12-hour estimate accounts for thorough subfloor preparation, proper mixing and curing times for the mortar, and precise leveling, all of which are crucial for the long-term success and integrity of your shower.
Why is a mortar bed absolutely necessary for securing the shower pan, and can't I just use construction adhesive or shims to level it?
A mortar bed provides full, even support across the entire bottom of the shower pan, preventing future cracking or movement that can lead to leaks and pan failure. Construction adhesive or shims alone won't distribute weight evenly and can leave voids, compromising the pan's structural integrity over time. The mortar ensures a solid, stable foundation.
What are the most common mistakes beginners make when installing a shower pan that lead to leaks, and how can I avoid them?
Common mistakes include not properly sealing the drain connection, failing to achieve a perfectly level mortar bed, and inadequate subfloor preparation. To avoid leaks, ensure all drain connections are tightly secured with the correct sealant and fittings, meticulously check the pan's level in all directions before the mortar sets, and prepare a clean, dry, and structurally sound subfloor.
The project mentions subfloor preparation. What specifically do I need to do to my subfloor, and how can I ensure it's protected from moisture long-term?
Your subfloor needs to be clean, dry, solid, and free of any rot or damage. Repair any soft spots or unevenness before installation. To protect against moisture, consider adding a layer of cement board or a waterproof membrane before setting the pan, and ensure a generous application of Loctite Silicone Waterproof Multipurpose Adhesive Sealant around the drain opening.
