Bathrooms are characterised, in general, as more restricted areas - they are not always the big, airey rooms we may hope for and, often, do not have natural light. As such, lighting becomes more important than usual. Lighting must be more intense than in the rest of our house, as compared with the needs of the room.
Task lighting: Task lighting should allow you to groom yourself efficiently, not create shadows and special effects, although no doubt it's fine if you can easlily incorporate those suitably in your lights arrangements. For task lighting around the mirror, place the light fittings on each side of it. The lighting should illuminate the person before the mirror rather than focus on the mirror. Generally speaking, the lights should illuminate your face fully and minimize shadows under your eyes and chin. It's also possible to wish to install lighting inside the bathroom cabinets so it is easier to consider things placed inside. Also install lighting fixtures over the bath area and toilet.
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.
Bathroom Lighting: Of all the rooms in your home, the bathroom specially need to be a well-lit area. Many people seem to forget about this details when designing their houses; in the end, you don't devote most of your day inside bathing room, so why go to all the expense? Well, if perhaps you don't want to, but a well-lit bathroom has its emotional advantages and it helps physically too to be able to see clearly and walk safely and securely in the bathroom.
