The Recessed Bathroom fan is installed in the ceiling so that only a small part of the fan or grill is visible. Recessed bathroom fans from Broan and Fantech are available with or without a light and offer effective exhaust of moisture in the bathroom, without taking up a lot of ceiling or wall space. Single grill bathroom fans are designed for use in one room, while dual grill recessed bathroom fans can be used in two separate bathrooms, for double the coverage. Exterior mounted fans are installed outside, but the fan itself mounts into the bathroom ceiling for areas with limited space or where direct venting is necessary. KitchenSource.com features recessed bathroom fans with CFM ranging from 70 to 230, to accommodate bathrooms of every shape and size.
