How can I add an exhaust fan to my basement?

I just had this done. Because my house is super old, and stone, there were no exhaust fans anywhere... They can go through one of your windows...( cut a circular hole, and attach the duct to the window with a special vent using superglue. ) In my case they went from my stone walled utility room with the dryer vent, through my bathroom near the ceiling, and through one of the windows, near the top. It looks a tad strange, at the moment ( exposed ductwork in a 220 year old stone room ) but it will alleviate what was about to become a serious mold problem. There had never been a dryer in the house. I'll keep haunting pinterest to find a fun way to "hide" or feature it... but it's much better than what I was facing. Good luck with yours.

( After going through two stone walls, venting through the window was 'cake'.)

The PVC sounds great... I'll look into it... I left my joists exposed, but the PVC sounds like a better choice than what my contractor went with in between. Hah! We are in agreement when it comes to acoustic panels , and/or pegboard. :-)

Thanks for the info!
