Indoor and outdoor ceiling fans come in the same styles and offer the same functions, however, be aware of the location rating of the fixture. Location ratings determine what kind of environment that fixture can be installed in, ranging from dry to damp to wet. A dry environment is any space indoors without moisture or the risk of water getting on the fixture. A damp rating allows for indirect moisture such as condensation build-up in a bathroom, while a wet rating means the fixture can be directly exposed to sprays of water without damaging the electrical components.
