How To Lay A Shower Pan: A Personal Experience

When I decided to renovate my bathroom, one of the most important things on my list was to install a new shower pan. I had heard horror stories from friends who had tried to do it themselves and ended up with leaks and water damage. But with some research and careful planning, I was able to successfully lay a shower pan on my own. In this article, I’ll share my experience and provide a step-by-step guide, as well as some tips and ideas to make the process easier for you.

Step-by-Step Guide

Step 1: Prepare the Area

Before you begin, make sure you have all the necessary tools and materials. You’ll need a concrete or mortar mix, a trowel, a drain assembly, and a waterproof membrane. Remove any old flooring or debris from the area and clean it thoroughly. If necessary, level the surface with a self-leveling compound.

Step 2: Install the Drain Assembly

Place the drain assembly in the center of the shower area and mark the outline. Cut a hole in the subfloor to accommodate the drain. Apply plumber’s putty around the flange of the drain and insert it into the hole. Tighten the screws to secure it in place.

Step 3: Mix and Pour the Mortar

Mix the concrete or mortar according to the manufacturer’s instructions. Spread it evenly over the subfloor, using a trowel to smooth it out. Make sure the surface is level and slope it slightly towards the drain to ensure proper drainage. Allow the mortar to dry for at least 24 hours.

Step 4: Install the Waterproof Membrane

Cut the waterproof membrane to fit the shower area, leaving a few inches extra around the edges. Apply a layer of thin-set mortar to the surface of the dried mortar and smooth out any wrinkles in the membrane as you lay it down. Overlap the edges and corners and seal them with waterproof tape. Allow the membrane to dry for at least 24 hours.

Step 5: Apply the Final Layer

Mix another batch of mortar and spread it over the waterproof membrane. Use a trowel to smooth it out and slope it towards the drain. Allow it to dry for at least 24 hours before installing the tile or other flooring material.

Top 10 Tips and Ideas

Use a pre-fabricated shower pan if you’re not comfortable with laying your own.
Choose a waterproof membrane that is compatible with your mortar or concrete mix.
Make sure the shower area is completely dry before installing the waterproof membrane.
Wear gloves and protective eyewear when mixing and handling the mortar or concrete.
Use a level and slope the surface towards the drain to prevent standing water.
Seal all edges and corners of the waterproof membrane with waterproof tape.
Allow each layer to dry completely before proceeding to the next step.
Consider adding a layer of thin-set mortar between the waterproof membrane and the final layer of mortar for added protection against leaks.
Install a shower liner beneath the waterproof membrane for added protection against leaks.
Consult a professional if you’re unsure about any aspect of the installation process.
