Spray Paint
Paper and Pencil
Shower Surround

Installing a shower over a basement drain is relatively a simple project. It is a great remodeling project and can help to add long term value to your home. It is a project that yields a pretty good return on investment, when you consider all the other projects you may look to complete for home remodeling. Here is a simple process to follow when remodeling your basement and installing a shower over a basement drain.

Step 1 - Locate the Basement Drain

Locate the basement drain. The drain in the basement will either look like a small pipe protruding from the cement basement floor, or it will have a small grate around it with open holes. The grate will not be very big, only 3 or 4-inches in diameter. Once you have located your drain, make a small “X” on the floor over the drain with spray paint.

Step 2 - Design Your Basement Shower

Using a piece of paper and pencil, design your basement shower. Place the shower in close proximity to the drain, as it will make both the installation and the ongoing maintenance of your basement shower easier. The flow of water will work much better when the shower is located near the drain.

Step 3 - Break-Up a Section of the Floor

Break-up a section of the basement floor. Cement basement floors are installed and reinforced with rebar. Remove all rebar or mesh from the piece of flooring you have broken. Install a trap beneath the drain.

Step 4 - Add Ventilation

Ventilate your shower drain using the outside ventilation stack for your home.

Step 4 - Frame the Shower

Add a frame around the shower. The framing will create the walls for your basement shower. If you plan on using a fiberglass shower surround, read the manufacturer directions for any specific instructions or requirements for your framing project.

Step 5 - Install the Shower Surround

Install the shower surround pieces. If you are using fiberglass, install the surround inserts. Secure them with screws or nails, whichever is required by the manufacturer. Double check the drain as you install the surround panels. Run water into the drain and look leakage. If you see leaks, double check the piping and the piping connections.

Step 6 - Attach Faucets and Plumbing Fixtures

Last, but certainly not least, attach the plumbing fixtures, such as the faucet for your basement shower.

Step 7 - Attach Curtain Rod and Curtain

If your shower is going to use a shower curtain, attach the curtain rod and the shower curtain. Test your shower’s function as well as the flow of water and the drainage.

Step 8 - Clean-Up

Clean-up your work area, wash the walls with a cleaning detergent, and dry everything. Put your tools and materials away, then enjoy your basement shower.
