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.
Lighting for the bath come in two options: either those who are already incorporated in the furnishings, or those you buy separately. Choose a filament lamp bulb for a small cost, in a bright colour, similar to natural light. Choose a spotlight if you want something to consume less energy, but a bigger price than a bulb. And if you choose the neon light take into consideration the colder light and the higher price.
If you want to look your best then you'll probably spend a fair bit of time in the bathroom, but unless you have decent bathroom lighting you may not be seeing yourself in the best light.
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.
