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.
Try accent lighting for illuminating your bathroom as it accentuates the lighting in your bathroom. This lighting option is not a necessity, but can be used for creating a decorative and dramatic look for your bathroom.
There are lots of varieties and styles of beautiful flush and semi- flush ceiling mounts of bathroom lighting fixtures available in the markets, which will go well with the mood of any bathroom.
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.
