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.
This space is one can be a room for relaxation, though it is also a functional space, and the moment we think about what lighting to use we have to think about all these things. Efficient lighting will allow us to carry out all the activities relating to these rooms without creating any discomfort.
Accent lighting: Accent lighting, as the name suggests, draws attention to a certain area or feature of the bathroom. You can use it to good effect to highlight things like an ornate mirror or an artwork or a decorative wash-basin or beautiful tiling.
Remember that different kinds of bathroom designs require different kinds of lighting. The lighting you choose for your bathroom will be largely dependent on the room design, personal choice, as well as the bathroom setup. Make sure that the lighting in the bathroom is just right, not very bright and neither too him.
