The cost of installing a bathroom fan is $350 - $400.
A bathroom fan is a common and effective way to circulate air in a small space, allowing for better circulation and lower humidity. Adding a bathroom fan can help prevent future mold or water damage issues. For this example, we’ll look at the cost of installing a fan in a standard 5’x8’ bathroom, which averages $350-$400. DIY-ers can install their own bathroom fan but an an electrician can be hired.
Most bathroom fans are installed on the ceiling. A standard exhaust bathroom fan costs $70-$120. A combination fan and heater costs $110-$210. A combination fan and light costs $100-$175. A combination fan, heater, and light costs $125-$225 on average.
There are two key factors in choosing a fan: CFMs and sones 1. CFM, or cubic feet per minute, is a measurement of airflow. The larger the room, the higher the CFMs you need. A standard 5’x8’ bathroom needs a fan with 70-90 CFM, while a larger bathroom requires a 100-plus CFM fan. Fans with higher CFMs are more expensive by around $30-$60. Sones 1 are the measurements to indicate how loud a fan is. Look for a fan with 2 sones 1, which is considered quiet.
Most electricians charge $65-$85 per hour and can install a bathroom fan in 2-4 hours, for a total labor cost of $130-$340. In general, replacing an existing fan with a newer model is easier and less expensive because the wiring is already in place.
Adding a new fan typically requires adding new wiring or reconfiguring old wiring or ductwork. If wiring or ductwork needs to be changed or rearranged, the installation can take longer and be more expensive. Electricians typically change the wiring in one to two hours, for a total cost of $65-$170.
To install or change air ducts, plumbers typically charge $45-$65 per hour and can finish the process in one to two hours, for a total cost of $45-$130.
A standard 5’x8’ bathroom requires between 70 and 90 CFMs, while a larger bathroom will require a fan with more than 100 CFMs.
The size of your fan should relate directly to the size of your bathroom. A standard size bathroom needs a fan that can handle 70-90 cubic feet per minute of airflow.
Broan vents are designed to vent your kitchen or bathroom through a wall, and are usually installed in conjunction with a fan as part of a kit.
Ideally, yes, as the humidity that is being pulled from the bathroom needs to go somewhere. Fans emptying into the attic space could lead to mold or mildew growth over time.
