How Bathroom Light Fixtures Work How Bathroom Light Fixtures Work

A basic component of any bathroom, light fixtures serve a very basic yet twofold purpose. On the one hand, bathroom light fixtures conceal the wiring that makes lighting possible. On the other, they support the bulb or lamp that is powered by that wiring. In addition to these two very basic tasks, light fixtures in the bathroom help to define the sense of style present in that room. Often it's the light fixtures that determine the décor of a room. They're one of the first things a guest sees when they enter. In this way, bathroom light fixtures serve a very aesthetic purpose as well.


Without bathroom light fixtures, bulbs would either hang haphazardly from the ceiling or the wall, attached to a tangle of wires providing them with power. Light fixtures offer a structure for the light. Whereas they, in themselves, do not power the light bulbs, they mount to a wall or ceiling and conceal the wires that run behind the drywall. Therefore, their function is in their form. In addition to the concealment of wires and the holes in the wall through which they come, light fixtures support the light bulbs in a variety of ways. Whether the bulbs screw into an upside down, ceramic fixture with a glass bowl encapsulating it or if they screw into sockets atop ornamental brass arms installed above a mirror, light fixtures give the bulbs structure and form.

Fixture Placement

The placement of the light fixtures can have a profound impact on how light reaches people using the bathroom. Mirror light fixtures are especially sensitive, for they must provide enough light without being glaring and yet also not reveal too much about a person’s image. It may sound strange, but mirror or vanity lights in the bathroom need to do their part to flatter the onlooker. Fixtures are wired to be compatible with light bulbs of certain wattage. That is more a matter of the light bulb you decide to use in the bathroom, but the position of the fixture is equally important. If it is too high, it may provide inadequate light. If it is too low, however, the light could shine right into a person’s eyes. Thus, in addition to providing a structure for the light bulbs and concealing the wiring, light fixtures must be placed in the right spot to achieve their desired effect.


Light fixtures in the bathroom serve an aesthetic purpose as well. They do much to influence and augment the style and décor of a bathroom. For example, a bathroom furnished with wainscoting, antique porcelain sink and tub and other old fashioned decorations would not suit a modern looking or even art deco light fixture. It would be completely out of place.

Bathroom light fixtures have a very practical function, namely, concealing the bathroom electrical wiring that protrudes from the walls and ceiling, the holes that it creates and providing sockets for the light bulbs. They also help to make the bathroom whatever style it aims to be.
