I've recently renovated my bathroom. It is about 75-80 square feet (12 feet by six feet), rectangular in size with the bathtub/shower placed crosswise at the far end of the room from where the door is.
Previously, the bathroom fan was located more in the middle of the room; however I wanted to relocate the bathroom fan into the shower and use a fan/light combination.
I installed the new fan (Air King BFQF70) at 70 cfm directly in the shower.
I also installed a new ceiling (smooth painted versus the old popcorn texture) and repainted the walls.
Upon finishing the project, we noticed within a week that condensation was accumulating on the ceiling and upper walls, and then running down the walls, leaving ugly streak marks. I tried washing and repainting the walls, then letting the paint fully cure for a week before operating the shower. Problem recurred.
I upgraded to a 120 cfm fan and while this slows the condensation process down, the streaks eventually come back.
I do like hot, steamy showers, but I've never had a problem like this before with my old bathroom set up. I feel 120 cfm should be more than adequate for this size room.
What am I missing here?
Thanks in advance for any advice.
