There is no rule such that the bathroom lighting should be provided only in the ceiling or is better if it is provided at the sides or on top of the mirror. One has to fix the bathroom lightings according to one's taste and the mood that he or she wants to bring into the room. Even for a small bathroom, people, these days, go for two or more lighting fixtures. Thus, lighting is the most important factor to be considered in any modern bathrooms.
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.
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.
