A simple tip to help you size
a fan for your bathroom
IF your bathroom is 100 sq.ft. or smaller
According to the guidelines of HVI (Home Ventilating
Institute) baths that are 100 sq.ft. or smaller require
1 CFM per square foot of bathroom or a minimum 50
CFM of fresh airflow. To find the square footage simply multiply the length of the bathroom by the width.
For proper airflow in typical installations (when
duct losses aren’t calculated), use the 0.4” Ps (static
pressure) rating point for correct fan selection.
IF your bathroom IS over 100 sq.ft.
Ventilation for baths over 100 sq.ft. is calculated
based on the fixtures in the bath. Allow 50 CFM for
each standard toilet, shower or tub. Whirlpool and
jetted tubs are calculated at 100 CFM. Add up the
CFMs for all fixtures and you will have calculated the
total CFMs required.
We recommend that steam showers use a separate
fan on a timer so that the fan may be shut off during
shower use and then run afterward to dry the
shower stall.
