The first thing to consider is the look of the light itself. This may be a wall light, bathroom mirror light or ceiling light, and each of these types offers a whole variety of choice. If you have a bathroom with chrome based fittings, such as chrome taps, chrome towel rails and chrome handles on bathroom cupboards then it's probably a good idea to consider opting for bathroom lights with a chrome finish. Nickel plated lighting offers a beautifully warm look, but it's generally best to complement chrome with chrome rather than mix nickel and chrome together.
Task lighting: Task lighting should allow you to groom yourself efficiently, not create shadows and special effects, although no doubt it's fine if you can easlily incorporate those suitably in your lights arrangements. For task lighting around the mirror, place the light fittings on each side of it. The lighting should illuminate the person before the mirror rather than focus on the mirror. Generally speaking, the lights should illuminate your face fully and minimize shadows under your eyes and chin. It's also possible to wish to install lighting inside the bathroom cabinets so it is easier to consider things placed inside. Also install lighting fixtures over the bath area and toilet.
So, for example, zone 1 is the wettest location, being around the bath and shower. Zone 2 is slightly less soaking, being just outside the immediate bath, shower and basin areas, and zone 3 is the furthest away from these sources of water. So if you're looking for designer bathroom lighting to create a well lit bath or shower area, look for zone 1 lighting, and for bathroom mirror lights and designer bathroom wall lights, bear in mind you'll need either zone 2 or 3.
Uniform light can be expressed through various bodies, selected according to the size of the bathroom. For a small bath uniform light can be obtained with the help of two bodies of lighting arranged on either side of the mirror, and for a large bath the light may be obtained by using a lightning body affixed to the ceiling, above huge mirrors.
