A bathroom exhaust fan is a virtual necessity to install in a bathroom. It removes all sorts of unwanted odors and smells from the bathroom. Moreover, it eliminates moisture, which, in turn, leads to the eradication of mold and mildew that would cause the paint on the walls to peel off.

Bathroom doors and cabinets will also be saved from mold buildups. Installing a bathroom exhaust fan is a task which can be done yourself and requires only a few hours of your time. Follow the steps described below to add a bathroom exhaust fan in the wall.

Step 1 - Turn off Electricity

The first step is to turn off the electricity of the bathroom from the breaker box. This is essential in order to prevent getting shocked.

Step 2 - Trace Position of Fan and Cut Out Hole

Before starting any of the described steps, it is best to make use of the rubber gloves and goggles, especially when using equipment such as drills. Also, ensure that the bathroom floor has been dried off completely and has no water spilled on it to avoid shocks.

Choose the exact area where the exhaust fan will be installed. Pick up the fan’s housing and, using its inner portion, trace the edges of it onto the wall with a marker. Using the drill now, make holes through the interior wall at the four corners on the tracing. Place the saw in one of the holes and start cutting from hole to hole until an entire section of the interior wall has been cut out. However, when doing so, make sure that you know the exact locations of other wires and pipes in the wall and that you do not cut through them.

Step 3 - Make Template and Insert Screws

Follow the exact same process as above to create a template for the exterior wall on a piece of cardboard. This template will be lined up against the actual exhaust fan’s casing. Using a drill again, make holes so that the exhaust fan can easily be fixed onto the wall. Then, fit the exhaust fan into the opening and pinpoint the location of the screws on the exhaust fan’s housing using the ice pick. Make sure it reaches the exterior wall and leaves a prominent mark on it so that the fan can be properly aligned against the wall.

Step 4 - Attach Fan to Wall

Drill in holes where the screws are present in the exhaust fan, and using a screwdriver, ensure that the screws have been fit tightly into the wall. In order to ensure that the electricity is completely turned off, insert the black wire of the exhaust into the voltage tester to check it.

Step 5 - Connect Fan to Main Electricity Connection

Once it has been ensured that there is no electricity running, run the wire of the exhaust fan through the wall and make sure it is long enough to reach the breaker. Next, match the colors of the wires of the exhaust with the main circuit and connect these together. Once they have been firmly connected using a screwdriver, turn the power supply back on. By now, the fan should be properly installed and ready to provide you with a well-ventilated bathroom.
