We just moved into a brand new home with highish ceilings (around 9-10 feet) with a proper vents installed in the bathrooms and the kitchen. My question is about the recessed lighting in the bathroom. Currently, it is not enclosed at the roof by a glass lens. There is so much condensation in the bathroom when we take a shower. I worry that the recessed lighting should be covered, with a glass dome so steam/condensation won't get into the roofing material and cause mold and other issues. Is this a legitimate concern?
