The bathroom is a very important room that everyone has to visit. This is the room that gets you and your family ready to greet the world on a daily basis. As a result, it is very important that it is properly lighted to send you on your way looking your best. This room above all the others is more than likely to be visited by guests when they stop by from time to time.
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.
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.
It is wise to use flush-mounted ceiling fixtures, owing to the fact that these come with bulbs that are enclosed by a kind of cover. The cover is essential as it acts somewhat like a lamp shade and helps in diffusing the light as well as protecting hot bulbs from breaking and cracking from contact with water vapor. The best would be to have the right balance of ambient bathroom lighting and task bathroom lighting. This will give your bathroom proper illumination and make your bathroom experience worthwhile.
