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.
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.
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.
Another aspect to consider as far as the look of the bathroom lighting is concerned is the type of shade you use. Frosted glass offers a diffused light, which is both soft and very much easier to work with if you happen to be taking advantage of a little privacy and a mirror to carry out your ablutions and pampering.
