In a situation of a exhaust fan or exhaust fan / light combo that is to be used in an above bathtub or shower area, the fixture must be specifically approved for that purpose and must be GFI protected. Heavier units require additional support independent of the box itself.


There is special electrical boxes designed to mount a fan / light combo unit and is a requirement in electrical codes of a lot of jurisdictions (ask about these at your local electrical supply store). These wiring options are suitable for both paddle fans / light combos as well as exhaust fan / light combo units.
