Okay I actually do understand the purpose of the bathroom fan; it gets the steam out of the bathroom after a super hot shower, right? Well turns out I never turn it on. I suppose I don't shower in sauna temperatures. Also we tend to shower with the door open.
Or, is the point that it rids the room of odors? Thus, the nickname 'fart fan'
The duct from the bathroom fan simply terminates in the attic space. I've been reading the threads explaining the reasons to vent it to the outdoors, but I don't want to. I have a beautiful house with new cedar siding and I don't want to ugly it up with a big vent sitting in the middle of the gable.
So here's the question; why? Can't I simply not use the fan? The steam or stink doesn't bother me. Do I need to put an end on the vent I don't use?
