Step-by-Step Guide to Installing a Bathroom Exhaust Fan
When the bathroom is foggy after taking a shower, it often means the exhaust fan is not working properly. The excess moisture left in the air after showering can cause a major problem—namely mold. This is why it is so important to have a working exhaust fan in the bathroom to help clear the steam and prevent mold from growing. Luckily, the installation of exhaust fans is pretty simple.

Choosing a New Bathroom Exhaust Fan
When choosing a new bathroom exhaust fan, it is important to pay attention to the sones and CFMs. CFM, which means “cubic feet per minute,” measures airflow—so, the bigger the room, the higher CFM needs to be. For example, a small powder room needs 50 to 60 CFM, and a larger, master bathroom needs 100 CFM or more. Sones indicates how loud the fan will be when it is operating.
Directions for Installing a Bathroom Exhaust Fan
- Turn off all the power to the fan.
- Remove the fan cover and test that the power is off by using the circuit tester.
- Remove the fan motor and the mounting screws.
- Slide the old fan housing sideways to detach the duct.
- Remove the old fan housing.
- Label all of the electrical wires before they are disconnected for easier reconnection later.
- Hold the housing for the new fan to the ceiling to measure the size of the new hole.
- Cut a hole or adjust the current hole size using the drywall knife.
- The duct connector may need to be set into the ceiling before installation – hold up the housing, line it up with the connector using the slots, and move the housing into the space.
- The housing should remain square and level to the joists when driving the screws through the mounting holes.
- From the above access, attach supports to the joists.
- Connect the brackets to the body of the fan using screws.
- Using HVAC tape, attach the ducts to the connector.
- Remove the junction box cover.
- Connect the fan wires to the house wires based on earlier labeling.
- Replace the junction box cover.
