How much airflow is required for bathroom ventilation?

HVI recommends ventilation rates based on 8 air changes per hour. For most bathrooms this works out to 1 cfm per square foot of area, with a minimum of 50 cfm.

A bathroom less than 100 square feet:
- Calculate 1 cfm per square foot of floor area. A minimum of 50 cfm is the required ventilation rate.
A bathroom larger than 100 square feet:
- To calculate the proper ventilation rate, add the cfm requirement for each fixture; toilet 50 cfm,shower 50 cfm, bathtub 50 cfm, jetted tub 100 cfm. Note: For proper sizing,the static pressure (SP) needs to be calculated.

What is HVI?

HVI, also known as the Home Ventilating Institute, is an independent non-profit organization that certifies fan performance characteristics and provides HVAC guidelines for consumers. Learn more about HVI at HVI.org.
