Ambient lighting is another part of light layering. These are usually your typical uplights. They direct light upwards to allow the light to bounce off the ceiling and into the rest of the room. It softens the light and creates a good glow. Next is accent lighting. This is the kind of lighting that will give an additional spark to the lighting of the room. You can choose to dim it or increase the glare depending on your needs.
Also the light can be reflected by using mirrors if they are placed in strategic places and you can get better results when decorating the bathroom. It may also be supplemented by a lamp or lamps perched on the bathroom cabinet if the electrical system allows this. All these will help you to have a stronger light when needed, but also a dimmer light to create a romantic atmosphere.
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.
Another aspect to consider as far as the look of the bathroom lighting is concerned is the type of shade you use. Frosted glass offers a diffused light, which is both soft and very much easier to work with if you happen to be taking advantage of a little privacy and a mirror to carry out your ablutions and pampering.
