How to Install Recessed Shower Lights
Installing recessed shower lights can be an improvement to a dim shower area, but there is more involved in this type installation than you may think. Any fixture you install must not only be identified as IC (insulation contact) rated, but must also be waterproof. To install a recessed shower light in your shower, follow the instructions below:
Step 1 – Check Local Building Codes
There are likely to be regulations you must meet in installing your shower recessed lighting. To know what these regulations are and how they may apply to you, talk with an inspector in your local building code department to determine what kinds of fixtures can meet these codes.
Step 2 – Determine Your Needed Power Source
Since you will need electrical power to operate your new shower light fixture, you'll need to know the source of a power supply you can use. If you plan to install your fixture in a location presently not served by power, you'll need a nearby outlet or switch to connect your new fixture to. If you are simply replacing a fixture that already has power, you will find this installation to be less costly and time consuming.
Step 3 – Shut of Power
To ensure that power to the electrical circuit to which your new receptacle will be connected will be safe to work on, turn off your power at your circuit breaker box. To be on the safe side, leave a note on this box advising anyone who sees it that work is being done with a receptacle, and that no power switch in the box should be turned on. Then, use a circuit tester to be sure the power to your circuit is turned off.
Step 4 – Cover Your Shower Drain
To keep debris and dust from falling into your shower drain and clogging it when you cut into your shower ceiling drywall, cover the drain and tape it to keep the cover from shifting away from the drain.
Step 5 – Determine Your Fixture Location
If you are installing a new fixture, you'll need to determine the location on the ceiling where you'll install it. You'll need to cut a hole in your ceiling for the light canister to fit into, so use a stud finder and locate 2 studs between which you can cut your hole.
Step 6 - Check for Ceiling Clearance
Before cutting your ceiling drywall, go into your attic above our shower and be sure there are no pipes or electrical wires that might be cut. Then, return to your shower and cut a hole, using your drywall saw.
Step 7 – Install Your Fixture and Wiring
Attach the canister housing to the ceiling. If the canister is heavy, attach it to one of the ceiling joists. Run your electrical cable from your source electrical receptacle to your new fixture, and connect both wire ends, using wire nuts and standard wiring connections.
Step 8 – Finish
When wiring and fixture installations are done, turn on your power and check the fixture lighting to be sure it is working.
