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.
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.
It is wise to use flush-mounted ceiling fixtures, owing to the fact that these come with bulbs that are enclosed by a kind of cover. The cover is essential as it acts somewhat like a lamp shade and helps in diffusing the light as well as protecting hot bulbs from breaking and cracking from contact with water vapor. The best would be to have the right balance of ambient bathroom lighting and task bathroom lighting. This will give your bathroom proper illumination and make your bathroom experience worthwhile.
