How to Install a Concrete Shower Base

By Lacy Enderson
Install a Concrete Shower Base

Installing a concrete shower base properly is the difference between a shower base that leaks and one that is solid. Laying a concrete base before installing a shower pan must be done to prevent water from leaking into the walls. Excess moisture can cause mildew and wood rot. Install the concrete shower base properly and your shower pan is likely to fit better.

Build a dam on your shower floor by placing 1-by-6 boards along the existing layout.

Cut the boards to length with a miter saw.

Attach the corners of the boards together with screws.

Place the shower pan liner over the shower layout and cut along the outside edges, allowing an extra 5 inches on each side. The extra liner is what extends up the side walls.

Layout the trimmed shower pan liner, pulling it tightly towards each corner.

Smooth out the bottom of the liner so it is ready for the concrete.

Cut out the shower pan liner around the drain.

Remove the top flange and mold the liner around the drain.

Replace the flange and attach the drain grill. Tighten the screws.

Mix your concrete in a bucket and pour it into your shower over the liner to form the base.

Add enough concrete to raise the level to your established height.

Smooth out the concrete with a trowel, making sure there are no bubbles or lumps.

Evenly distribute the concrete, avoiding the drain. Check it with a level before the concrete dries.
