How to Install a Bathroom Exhaust Fan and Electrical Outlet Like a Pro

Bathroom Exhaust Fan Having an adequate bathroom exhaust fan is essential for maintaining proper moisture control and removing odors. At Mister Sparky, our electricians are often called upon to install or replace these fixtures in bathrooms to help ensure that mold and mildew do not become a problem and bathrooms stay in the best condition for as long as possible. Another necessity that we often install in bathrooms are electrical outlets. When we install these components in a bathroom, we go through the following steps:


Prepare the Installation Site


A bathroom exhaust fan should be located midway between the shower and toilet. If you are replacing an old fan, simply use the same location. If not, pick a spot supported by joists on either side and one that doesn’t have pipes or other obstructions. First, drill a reference hole in the ceiling where you want the fan to be then clear the attic of insulation around the hole. Measure the fan housing and use a saw to cut the intake-port hole.


Install the Fan


When installing, begin by lowering the fan into place in the cutout. After ensuring proper orientation, you can extend the metal brackets and secure them to the joists. Attach the duct pipe to the fan and cut a hole in the roof or siding and install a vent cap to cover. Wiring of the fan can vary depending on the type of fan used and whether it is a new installation or replacement. Reading the manufacturer’s instructions is key. When wired, the cover can be put into place.


Electrical Outlet Installation


A bathroom electrical outlet can be added at the same time as an exhaust fan. Locate an existing switch or outlet close to where the new outlet will be. Simply run wiring from the existing outlet to the new location. Cut a hole in the wall to accommodate the new outlet and follow all wiring instructions that came with the electrical box.


Always ensure that the power is off before doing any kind of electrical work, and if you aren’t confident that you can safely install a bathroom exhaust fan, contact a licensed electrician from Mister Sparky to help. We are always willing to help DIYers finish the job, so contact us at [phone].
