Safety Factors: Last but not the least, keep safety factors in your mind when setting up your bathroom lighting fixtures. Hire a qualified electrical contractor to do the particular installing and always use fixtures and lights particularly intended for use in wet areas. Place lighting fixtures at least 6 feet away from the bathtub or shower.
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.
So, for example, zone 1 is the wettest location, being around the bath and shower. Zone 2 is slightly less soaking, being just outside the immediate bath, shower and basin areas, and zone 3 is the furthest away from these sources of water. So if you're looking for designer bathroom lighting to create a well lit bath or shower area, look for zone 1 lighting, and for bathroom mirror lights and designer bathroom wall lights, bear in mind you'll need either zone 2 or 3.
When it comes to lighting the interiors of your home, you cannot afford to ignore your bathroom. It is important to choose appropriate bathroom lighting that would not only provide illumination but also go with the décor of your bathroom. Bathroom lighting is a part of the broader category of home lighting.
