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.
There are smaller sizes of bathroom lighting fixtures that are easily available these days, which not only requires less space but also opens up a wide array of possibilities of bathroom lighting. It is always better to use a mix of ceiling mount as well as wall sconces type of fixtures to light up a larger bathroom. Most bathrooms there days are more spacious as well as luxurious. To light up these types of bathrooms is a task that one has to carefully undertake to produce the desired results.
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.
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.
