Bathroom lighting can be added to the wall or ceiling, however, wherever the lighting comes from, it must be watertight so the steam from the bathroom would not affect it. If you want to bring a note of originality to your bathroom and to win some space, you can opt for ceilings with incorporated lights, like spotlights. Before thinking about the appearance and aesthetics of the lighting in your bathroom, you must first take into account how to protect users against electric shocks.
By using light fixtures with dimmer control, you will alter the intensity of the light to get exactly the required relaxing feel. Dimmers are also energy-savers and your lights will last longer. Just keep in mind that you would need incandescent dimmers for incandescent and halogen lights and agreeable dimmers for any other kinds of lights.
The bathroom represents a significant, strictly functional area of the house and therefore we must give it special attention when planning to decorate, both in terms of the bathroom suite and the lighting fixtures.
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.
