Hi all, I’d like to install an exhaust fan in my down stairs bathroom, however I think it is near impossible, as the walls are tiled to the ceiling and the roof is a concrete slab. There is a window to the side of the shower with a PowerPoint underneath, what is the best way to ventilate my bathroom? Given I can’t really exhaust the air anywhere but through the window and it would be impossible to hard wire unless I rip up some tiles to get the cable to the window spot. I can’t seem to find any exhaust fans that have a plug on them.
