How to Install an Electrical Outlet in a Bathroom

Updated February 21, 2017

An electrical socket can be installed in a bathroom if the number out outlets that are currently available is not sufficient. Installing an electrical socket in your bathroom will require running wires from an existing outlet or switch to the location of the new outlet. A hole will then need to be cut in the drywall to insert the electrical box. You can install an electrical socket in your bathroom by first deciding where the new outlet is going to be located.

Disconnect the power to the bathroom by turning off the breaker on the circuit box.

Determine where the new electrical socket is going to be located. The outlet should be located directly beneath an existing switch to easily run the electrical wires.

Locate a stud on the section of the wall where you want to install the outlet using a stud finder. Mark the location of the stud with a piece of painters tape.

Measure from the floor up the wall to where you want to install the outlet. The top of the outlet needs be at least 14 inches up from the floor.

Place a piece of tape on the wall where the outlet is going to be located. The tape should be on the same side of the stud as the light switch.

Place the electrical box on the tape mark for the outlet location and trace around it with a pencil.

Drill a small hole in the drywall with a power drill.

Insert the drywall saw in the hole and cut around the outline on the wall.

Remove the light switch from the wall. Take off the cover plate with a screwdriver and then remove the screws that are securing the switch in the electrical box.

Run electrical wire from the switch to the hole for the electrical socket. Use a fish wire to feed the wire from the switch to the hole.

Place the electrical box in the wall and secure it to the stud with screws using the power drill.

Connect the electrical wires to the electrical socket. Connect the black wire to the gold screw, the white wire to the silver screw and the ground wire to the ground screw.

Secure the outlet to the electrical box with the screwdriver.

Connect the electrical wires to the light switch. Cut the existing black and white wires from the light switch, leaving about 6 inches of wire connected to the switch.

Strip about 1 inch of insulation from each of the black and white wires.

Twist the black wires together and the white wires together. Place a wire cover over each of the wires and wrap the them with electrical tape.

Connect ground wire to the light switch to complete the wire connections.

Secure the light switch to the electrical box using the screwdriver.

Turn on the power to the bathroom and see if the switch has power.


Cover plates can come in larger sizes if needed to cover the hole that was left in the wall. Electrical connections that require wire covers are called pigtails.


Turn the power off before attempting any type of electrical work.
