bathroom lighting

Bathroom lighting is highly dependent of the bathroom size and shape. Small bathrooms might only demand a central ceiling fluorescent fixture (or a ceiling fan with a light kit), and a pair of vanity fixtures, but larger bathrooms will demand a more complex lighting.

Bathroom lighting should be basically simple and functional. Since bathroom lights are usually used for relatively short periods, fluorescents aren't sufficiently advantageous.

Bathroom Vanity lighting

Do not put fixtures over the mirror if you want to avoid casting shadows on your face. Lighting fixtures should be mounted on either side of the vanity mirror, 35 - 40 inches (0.9-1 m) apart.

Fixtures can be placed on the mirror's surface, if the mirror is too large. To get even illumination and avoid shadows, each fixture should be located at the head level.

Bathroom general lighting and moisture

Installing a qualified exhaust fan with a build-in light is often a good option for bathrooms. The fan will provide both good ventilation, lighting and... energy savings).

Ceiling fan basics

Exhaust fans with light, use two separate switches: one for the fan and the other for the light source (and eventually a third for a night light).

Other lighting elements

Small recessed spotlight directed to some decorative elements are common in larger bathrooms. This kind of lighting is technically called accent decorative lighting, and its goal is mainly decorative and restricted to small areas and details.

In large bathrooms, the shower area may demand specific ligting, often based on a recessed light with a glass lens.
