Proper lighting in the bathrooms is most essential as in the case of other rooms in the home. The right type of bathroom lighting fixtures ensures that one can easily locate all the toiletries placed in the bathroom as well as have proper lighting for relaxing and reading books and magazines and also will aid a long way in shaving properly without any cuts or scars on the face.
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.
By using light fixtures with dimmer control, you will alter the intensity of the light to get exactly the required relaxing feel. Dimmers are also energy-savers and your lights will last longer. Just keep in mind that you would need incandescent dimmers for incandescent and halogen lights and agreeable dimmers for any other kinds of lights.
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.
