How to Install a Bathroom Light Fixture

To install a bathroom light fixture, remove the nuts or screws that hold the old light fixture onto the electrical box, after first turning off power to the light fixture at the main circuit breaker box.

Then remove the old light fixture from the wall. Also remove the mounting bracket that attaches to the electrical outlet box.

Next, twist off all of the wire nuts that connect the hot, neutral and ground wires together between the light fixture itself and the electrical box wiring. Now, attach the new bathroom light fixture mounting bracket to the electrical box, securing it with the original screws that held the original mounting plate. The new bathroom light fixture may also have some screws that you can use to attach the mounting plate.

Next, attach the ground wire on the bathroom light fixture to the ground wire coming out of the electrical box. The ground wire is the bare copper wire. Make sure to twist the wires first before attaching a wire nut to them.

Then attach the bathroom light fixture’s black wire to the black wire (or red wire) coming out of the electrical box. The black/red wire is the hot wire.

Finally attach the bathroom light fixture’s white wire to the white wire coming out of the electrical box. The white wires are the neutral, or return wires. Next, attach the light fixture to the mounting bracket. There should be small screws or decorative nuts to secure the light fixture to the mounting bracket. Now install any glass globes on to the light fixture.

Then follow by screwing in light bulbs into the light fixture.

Finally, turn power back on to the bathroom light fixture and throw the switch to the on position. With any luck you’ve successfully installed a bathroom light fixture.
