What Size Exhaust Fan for Bathroom
We moved into our home about 2 years ago. Our bathroom is relatively small at about 45 sq. ft. however we have a jetted tub. Currently there is a 70 CFM exhaust fan that isn't cutting it. Is 70 CFM enough for this small bathroom even though it has a jetted tub? Everything I find says if less than 100 sq. ft. use something fairly small but if greater than 100 sq. ft. you need 100 CFM for the jetted tub.
I haven't checked the ventilation yet but I assume it's an issue as well since this was a home project for the previous owner. Any recommendations on size of ventilation duct work?
