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.
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.
In giving your bathroom lighting a contemporary design it is very important that you include three categories of lighting, which are ambient, task and accent lighting. Recessed lights, pendant lamps or even rope lights that are hidden can be used to reflect the ambient light instead of using the everyday central lighting fixture in the middle of the bathroom. This will help to give your bathroom some amount of warmth while bringing that sophisticated and modern look to the bathroom.
Ambient bathroom lighting is a very popular choice For providing ambient illumination, the use of chandeliers and pendants are recommended. You need to keep in mind that bathrooms have the presence of a high degree of water vapor; this leads to the cracking of very hot bulbs which are exposed. Chandeliers and pendants have exposed bulbs, so think twice about their placement before having them installed.
