How to Install a Shower Base on Concrete Floor

Proper installation of the shower base on the concrete floor will make sure that it will not leak. You can always hire the services of a professional to do the installation. Take note that installing a shower base on a concrete floor can be difficult especially if you do not have any idea about shower base installation.

Prepare the Drainage Line

The first thing that you need to do is to prepare the drainage line. The fiberglass stall will ideally work for this type of setting. Most drains have existing pipes that you can see above the floor. In case there is none, you can create your own line that will facilitate the drainage of the shower base.

Check the Drain Pipes

The next thing that you need to do is to check the drain pipes. Drain pipes can exist two inches above the concrete. If there is no drainpipe, you can break the concrete to extend the pipe. Also, you should leave at least 1 to 1 ½ inch of space between the concrete and the pipe to successfully install the drain assembly. In case it is not visible, you can chisel the concrete to have the distance that you need around the pipe.

Mount the Drain Assembly

Make sure that the drain assembly is lock tightly into the pipe and clamps to the base edge of the shower. This creates a leak-proof seal that prevents hassles when using the shower. Once you are done with framing the walls for fitting the shower into the shower bay, the next step is to lay it on its back and install the drain.

Attach the Shower to the Drain

Roll out a coil of putty and wrap it below the drainage basket flange. Hold the drain basket and position it in the drain hole then slide the washers and thread on. See to it that you hand-tighten the ring of the exterior setting. Lower the basket assembly and shower bay above the drainpipe. You can mark the pipe to determine the ¾ inches measurement under the drain basket flange.

Lift the shower bay and cut the drainpipe according to the measurement that you have marked. Set back the basket assembly and the shower bay on top of the pipe. The next thing to do is to slide the gasket over the pipe and push it down so that it sits against the lid below the drain basket.
