How to Install a Bathroom Light Fixture Without a Junction Box

abc news

Are you planning to hang a light fixture in your bathroom but there is no junction box? That can be a pretty complicated task.

What most people would do is to create a hole in the drywall so they can run the wire through it then use plastic screw anchors to affix the lighting fixture to the wall. While this may seem like a good idea, you should know that this move may fall from the wall over time. You can get creative and install a smart LED shower head, but this option isn't for everyone.

The best way to address this problem is to install an old junction box which you can use to safely and securely attach your fixture to the wall. Related reading: a detailed guide on choosing a toto toilet.

The Ultimate Guide on How to Install a Bathroom Light Fixture Without Junction Box

Do you already have the mentioned items in hand? If yes, then let us proceed to install your bathroom light! Here are the steps that you need to take:

Step #1: Turn off the electricity.

Cut off the light’s electrical source by switching the main breaker's toggle switch to the OFF position which turns off the main circuit. In this way, there is no risk that you would get electrocuted. Always proceed safety rules and techniques.

Step #2: Cut out an opening in your wall for the junction box.

Find the place where you want to put your junction box. Hold the junction box in your target area and use a pencil to trace the back of the junction box on the drywall. After that, use a drywall saw to cut out that opening in the wall.

Step #3: Run the electrical wire through the box.

Get the junction box and punch a hole at its back. Afterward, run the electrical wire through it.

Step #4: Secure the electrical wire in place.

Put the junction box in the hole that you have created in the wall. Twist the locking screws of the junction box until the plastic anchors found at the back of the box is already seated right next to the drywall.

Once it is already in place, pull the box a bit to ensure that the anchor will have a bit of resistance. This time, tighten the screws until you are sure that the box is already securely attached to the wall.

Step #5: Split the wires.

Using a utility knife, cut off about 6 inches of sheathing the from the light’s electrical wire. After that, use a splicing tool to separate the wires and remove about half inch of the black and white wires’ plastic coating.

Step #6: Put the wires in place.

Get the white wires from both the box and lighting fixture and use pliers to twist them counterclockwise. Screw the cables on the wire nut. Do the same with your black wires.

Once you are done, twist the ground wires together.

Step #7: Attach the adapter to the electrical box.

Is there an adapter that comes with the light fixture that you have bought? If yes, screw it onto the junction box. You should also place all the wires of the lighting fixture inside the box. Using the screws included with the fixture, attach the light to the adapter.

Step #8: Test the light.

Now that you are already done, test if the light is properly working. Turn on the electrical source and see if the light would open. We hope it will!
