Massage room ventilation Massage room ventilation Besia (Industrial) (OP) 4 Dec 17 11:28 Hello, I am interest if massage room needs ventilation and if needs how is the specification. RE: Massage room ventilation moideen (Mechanical) 4 Dec 17 12:10 If consider the massage room is health club, then ASHRAE recommends 20 cfm/person and .06 cfm/sqft. RE: Massage room ventilation Ziggypump (Mechanical) 4 Dec 17 13:44 If it's an occupied space, then code requires ventilation. Code allows you to find the closest related space type to use. Also realize that code may not state a required ventilation rate, but an exhaust rate will be required. If you exhaust, you need to make-up, and that's how ventilation ties into the equation.
