Installing a bathroom exhaust fan costs about $400 on average, and most homeowners pay between $241 and $563.1,2 Replacing an existing fan is cheaper, around $200 to $250. A first-time install that needs new ducting and a vent costs more.1,2 Prices below are national averages* for 2026.

*National averages, not local quotes. Your price depends on whether a fan already exists, fan type and CFM, attic or roof access, duct length, and local labor rates.

Labor, ducting and permits

Labor, first install (average) $300 Fixr

Duct and vent, per Angi summary $250 – $950 Angi
Duct installation $450 – $2,190 HomeAdvisor

Angi and HomeAdvisor disagree on duct cost, so the table shows both. Angi also says permits are required for most new installs: HVAC permits average $250 to $400 and roofing permits $70 to $250. Check with your local building department.2

DIY or hire

Fixr estimates you can save about $150 by replacing an existing fan yourself, since the wiring and duct are already there.1 Turn off the breaker first and confirm the vent still runs outside. A new install means cutting a ceiling hole, running a duct and wiring a switch, which is where an electrician or handyperson earns the fee. Angi recommends new ducting over tapping an existing duct, which can trap moisture.2 Home Depot’s bathroom exhaust fan category lists fans by CFM and noise so you can match one to your bathroom.
