Hello, all. We finished remodeling our master bath (still need to post pics :-)) and have been enjoying our 6.5 ft shower. However, in this bath we have a way, way, way subpar ventilation fan. When I step out of the shower, you can see condensation on the walls. We have to blow fans, run subpar vent fan, etc. I called Broan up, and they suggested a 150 cfm fan would be adequate for the whole bathroom. The current fan has 4" duct work, and they suggested a 6" duct system. The configuration of our bath is roughly 8' x 11.' I am wondering if someone out there has any experience dealing with this, and can help me...do you think this 150 cfm fan with 6" ductwork will do the trick? What is the best product do you think for the application? Thanks everyone.
