Another important aspect in choosing lighting fixtures represent problems that may arise through contact between a heated bulb and water vapour from the bath. Such inconvenience can be avoided if spot type lighting bodies are used.
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.
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.
Now consider your bathroom space. You can try drawing the layout on a piece of paper. Indicate the natural light sources, such as your window and start putting ideas on the paper. Consider the various kinds of lamps available today, and where you can put them in the room. Have a main source installed. You can use this at night when natural daylight is absent. Next would be your secondary source, for your accent lighting. These are the bulbs that you can also use during the day to tie the lighting of the room together.
