I recently bought a split-level house, and the downstairs bathroom doesn't have an exhaust fan. Whenever anyone showers down there, the moisture builds up and beads on the paint, making it a bit of a mess. We can try opening the doors and a window, but it only helps a little. We're planning to repaint the walls with quality mold-resistant paint, but I'm eager to install an exhaust fan for better ventilation. The challenge is that there's a floor above the ceiling, so I can't just run ducting up there. I'm thinking of mounting a wall fan on the side of the wall facing the shower and running a duct under the ceiling to a cutout above the window. I'm wondering if this is a crazy DIY approach, or should I just hire someone? I can rent tools from Home Depot, but I have no clue about wiring it up. I'd probably have to hire an electrician for that part. What do you think?

You're on the right track thinking about the joists in the ceiling! Ideally, if they run in the right direction, you can route the ducting there. Yeah, fixing up drywall afterwards isn't super fun, but it’ll look much cleaner in the end. If you need a quick fix, a dehumidifier might alleviate some moisture until you can get the fan in. As for wiring, definitely consider hiring a pro for that part if you're unsure, it can be tricky.
That bathroom setup looks interesting! Installing the fan higher up above the window might work, but keep in mind that you'll lose some efficiency. I used to have a wall fan positioned above a stove, and it worked like a charm—just make sure to pick a fan designed for vertical use if you go that route. Also, remember that above the window might have obstacles like a header, so check those out before you decide.
I see what you mean! Yeah, I’d have to be cautious about the header above the window. Good to know a fan can work in that position if designed for it. Thanks for the tip!
Sounds like you've got a solid plan brewing for that exhaust fan! Just think through the process step-by-step, and don't hesitate to ask for help on the electrical side. It'll make the install much smoother in the long run!
Thanks! The joists actually run perpendicular to what I need, which is a bummer. I took my father-in-law's advice on that, and he seems to think it can't be done that way. Do you have any other suggestions?
