Lighting in bathrooms has stricter codes. Usually, it has to a certain height above wet areas which eliminates many hanging lights like chandeliers. Even if the light is in the "dry" part you still have to think about moisture in the air. Also, chandeliers tend not to give off great light so I don't recommend them for a bathroom unless there is plenty of other light sources.

You should find a damp location rated fixture in most stores. Ask for lighting fixtures marked "Suitable for Damp Locations" or "Suitable for Wet Locations"

The way electrical code defines this:

Dry locations are the areas not normally subjected to dampness or wetness. A location classified as dry may be temporarily subject to dampness or wetness, as in the case of a building under construction.

Damp locations are the area/s protected from weather and not subject to saturation with water or other liquids but subject to moderate degrees of moisture. Examples of such locations include partially protected locations under canopies, marquees, roofed open porches, and like locations, and interior locations subject to moderate degrees of moisture, such as basements, some barns, and some cold storage buildings.

Wet locations are area/s subject to saturation with water or other liquids, such as vehicle washing areas and in unprotected locations exposed to weather. and electrical components located underground or in concrete slabs or masonry in direct contact with the earth.
