It is indicated that you should use lighting fixtures directed down with special ornaments or decorative pieces which help in reshaping the bathroom and obtaining a special effect. Sources of lighting must be fixed and directed so to have an efficient light and to focus on dark areas or objects that you want to put in a special light.
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.
Try accent lighting for illuminating your bathroom as it accentuates the lighting in your bathroom. This lighting option is not a necessity, but can be used for creating a decorative and dramatic look for your bathroom.
Ambient lighting: This sort of lighting covers the general bathroom space. You could have a centrally fitted light - a chandelier, for example, if you want to opt for a special and creative effect - or several bright lights fitted all along the walls. If you are planning on installing recessed lights, be sure you install several recessed light fixtures or use recessed lights in combination with other styles of lights. Just a few recessed lights will not do the trick. Be sure you use glass lens over the recessed lights; plastic turns yellow with time.
