How to Install a Steam Shower Control Panel

Many homeowners opt to install steam shower for a spa experience right in the comfort of their homes. Because of the popularity of steam showers, many fixtures in a standard steam shower have been designed by manufacturers for easy installation. One of these features is the control panel, and here’s how you can install it to your steam shower.

Tools and Materials:

  • Power drill with 1-inch drill bit
  • Screw driver
  • Electrical/Masking tape
  • Waterproof silicon
  • Tape measure
  • Pencil
  • Steam shower control panel

Step 1 – Select a Location for the Control Panel

Check manufacturer recommendation for the correct location of the control panel: whether inside or outside the steam room. For an inside location, the best place will be on the same wall where the shower head is located. This location will prevent the control panel from getting sprayed by water from the shower head.

The inside location should also be far from the steam head so that it can detect the overall room temperature and not that of the steam head.

Step 2 – Drill the Access Hole for the Generator Wiring

Stand in front of the selected location and measure 4 to 6 feet from the floor to get the exact location. Use a pencil to mark the spot. Use a power drill to drill a 1-inch hole where the pencil mark was made. Be careful not to damage the surrounding tiles or wall material. When you are finished, turn off the water supply and breaker that connects to the steam room generator.

Step 3 – Complete the Electrical Wirings

Slip the control cable from the generator through the 1-inch hole into the inside of the steam room. Connect the ends of the wire to the correct terminals on the control panel connector. Avoid bending, stretching or pinching the control cable to ensure that the connection works properly. If you are not going to work on the connection immediately, cover the ends with tape.

Step 3 – Test the Control Panel

Turn on the breaker connecting to the generator and the water supply. Run a test on the control panel to check if the connection is working properly. Test all control panel settings as well. 

If the control panel is not working correctly, turn off the water and power supply again. Check the connections or call manufacturer’s customer service support.  

Step 4 – Install the Control Panel on the Wall

If the control panel is working correctly, peel off the backing of the adhesive at the back of the control panel. Coat the back with a good amount of waterproof silicone to block moisture from the cable connection.

While holding the control panel against the wall, slip the control panel connector and the rest of the connecting wire into the 1 inch hole carefully to avoid scraping. Then, firmly press the control panel against the wall covering the hole. Use a masking tape to support the weight of the control panel until the waterproof silicone has dried. This usually takes 24 to 48 hours.
