It was long overdue, but I finally installed a vent for the basement bathroom. It was inspired by Nick taking showers down there. Getting into the basement took a lot more work than I anticipated.
Then I just attached some duct to both ends and now the fan vents outside instead of into my basement. I think I am going to get a timer for the fan so you can just press a button when you start showering and it will run for a half hour or so. Otherwise I could see it getting left on, or turned off too soon.
