Bathroom Fan Installation questions, answered by experts

Not all exhaust fans need venting, but most do. Bathroom fans and range hoods work best when vented outside to remove moisture, odors, and pollutants. Some ductless range hoods use filters instead, but they don’t remove air—just recirculate it. Proper venting ensures better air quality and efficiency.

Every municipality has its own codes. But generally speaking, all bathrooms must have some ventilation, whether it's a fan or a window. Check your local building codes before doing any bathroom fan installation to make sure you are meeting the code requirements. A reputable electrician or bathroom fan installer will be able to answer this question.

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

The square footage of your room will dictate the correct ceiling fan blade size. For example: 

  • Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.

  • Rooms up to 175 square feet require 42- to 48-inch fans.

  • Rooms up to 350 square feet require 52- to 56-inch fans.

  • Expansive spaces over 350 square feet need a fan larger than 60 inches.

Basic tasks like replacing filters can be done by DIYers, but skilled technicians should perform full system inspections to ensure complete efficiency.
