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.
All the bathrooms, be it small, medium or larger ones, requires general lighting, which provides illumination to the entire room without any shadows and provides proper lighting to the floor of the bathroom. This type of lighting is often derived from the recessed ceiling bathroom fixtures that not only provide the light but also creates lesser glares when compared to the wall hanging fixtures. Natural light that is let through the windows which are made of frosted glass or glass blocks will also provide ambient lighting to the bathroom as well as privacy.
Bath lighting must meet three conditions: to be functional, aesthetic and to have a special ambiance. For the daily tasks (shaving, make up, etc.) you needed a strong light and for moments of relaxation, such as a bath in the tub, you need a discreet light. Also the bulbs that you use must provide the amount of light needed to properly light this room.
But the second aspect to consider when choosing your bathroom lights is safety. Clearly a bathroom is a wet area, and electricity and water are not the best of companions. Today however there's a very easy system in use which helps you to quickly and easily identify the type of light that's suitable for each area of your bathroom.
