I have an early-20's rowhome in Germantown. The bathroom is in the middle of the second floor, with no windows or access to outside walls. Ventilation is achieved through a skylight, set atop a five-foot shaft between ceiling and roof, topped with a door opened by pulling a chain. Ventilation is, to put it kindly, extremely limited. During this recent heat wave, I placed a thermometer in the bathroom and saw readings into the 90s during the evening (which is, unfortunately, bath time for my irritable preschooler). It has been quite unpleasant to bathe, brush teeth, or be in the bathroom during the recent heat. Has anyone found a ventilation solution for interior bathrooms, with or without skylights? Would it be possible (and affordable) to install a motorized ventilation/exhaust fan in or near the skylight? Would such a fan have any impact on the temperature? The skylight looks similar to the photo below. The chain opens a metal door, which provides very limited ventilation and nearly no temperature modulation.
