Good news, you do NOT need separate bath fans for each bathroom. With Aldes patented Zone Register Terminals (ZRT), installers place the fan unit in the ceiling in a location that is somewhat central to all of your bathrooms, so you can turn on the fan from any of your bathrooms and exhaust the humid air. Even better yet, since the unit is designed to be quiet, and it is physically located away from the grille, you won’t have to put up with any bath fan noise.
