How to Install an Overhead Shower Light Fixture

In addition to the light fixture, I needed some 20-2 electrical wire and a few wire nuts.

Before installing the overhead waterproof shower light fixture I first turned power off at the main electrical circuit breaker panel to the electrical boxes I planned to work on. I also checked that the power was indeed off at the electrical boxes using a simple bulb tester.

How to Install Recessed Shower Light Fixture Locate/Mark Center of the Shower The first step in installing an overhead shower light is finding the center of the shower on the ceiling. Next, I used a drill and small drill bit to create a pilot hole in the ceiling.

Installing Recessed Shower Light Fixture Can in Attic

I then proceeded up to my attic with my recessed shower overhead can lighting fixture and found the drill bit hole.

To provide power to the shower light, I ran a power cable from another light fixture that I had access to in the attic to a wall switch that controlled another light in the bathroom.

In addition, I also ran another electrical cable from the new overhead recessed can shower light fixture down to the same electrical switch box. It took me quite a bit of time, and another set of hands to fish the two electrical cables down to the electrical switch.

Once I had fished the two Romex cables into the electrical switch box, I connected the black wire associated with the power line to the top side of the electrical switch.

I then connected the black wire associated with the recessed overhead can shower light Romex cable to the bottom side of the switch. Next I twisted together all of the white return wires using a wire nut. I then twisted the ground wires together and fastened them to the green screw on the electrical switch. Finally, I reattached the electrical switch to the electrical box and fastened the faceplate cover back on to the electrical box.

Back in the attic and at the recessed can shower light fixture, I tied together the black wire associated with the Romex cable that came from the electrical switch box and the black wire in the can shower light.

Next, I attached the corresponding white wires together. Finally, I wired together the corresponding bare copper ground wires. I then put in a light bulb into my shower light fixture, turned power back on at the main service panel and tested my new overhead shower light.
