To the state the obvious, adding a window in your bathroom would be a costly undertaking—or, depending on the floor plan, simply impossible. But believe it or not, there's always the option of adding a skylight. Whereas a conventional skylight can only illuminate space directly beneath the roof, the Solatube Daylighting System operates in a different, more ingenious way. After capturing rays on the roof, the device channels light down through a compact, highly reflective tube measuring up to 40 feet. That enables Solatube systems to deliver natural light to virtually any room in the house. Best of all, tubular daylighting devices from Solatube International, Inc. install with minimal hassle, requiring no changes to be made on the framing and no ceiling or wall repairs inside the room. Indeed, while a conventional skylight usually takes days to install, Solatube takes only a couple hours.
