Bathroom Exhaust Fan Costs

Bathroom exhaust fans are a decorative and functional choice for doing ventilation. They remove hot and/or humid air from the bathroom by forcing the air outdoors. The ventilating action causes fresh outdoor air to be brought into the bathroom.

You will find that the cost of a fully installed average bathroom exhaust fan will vary by motor rating, fan dimension, mounting type, overall finish quality, and the labor rate.

In the following tables the Labor Cost figures are what the able DIY persons should expect to save by performing the complete installation.

Other considerations and costs

  • The bathroom exhaust fan generally helps to reduce indoor heat and humidity.
  • The exhaust fan location usually also provides lighting, and may provide heating.
  • During winter the house fan generally needs to be winterized to reduce air passage.
  • Taxes and permit fees are not included in these prices.
  • The installer must have the proper electrical and mechanical installations tools.
  • The installer must work safely atop a ladder, and be able to make necessary modifications and connections to an appropriate electrical circuit that passes near the fan location. 

DIY considerations

  • Other situations that require structural modifications of the building, or more extensive installations throughout the building, or new electrical circuitry are much more appropriate for professional service.
