Generally, whenever one talks about lighting a bathroom, a wall mounted fixture above the mirror props up immediately in one's mind. Even though, this is the most common type of lighting fixture known to people since last century, there are wide varieties and styles of lighting fixtures that are now available in the markets all over the world.
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.
Ambient lighting: This sort of lighting covers the general bathroom space. You could have a centrally fitted light - a chandelier, for example, if you want to opt for a special and creative effect - or several bright lights fitted all along the walls. If you are planning on installing recessed lights, be sure you install several recessed light fixtures or use recessed lights in combination with other styles of lights. Just a few recessed lights will not do the trick. Be sure you use glass lens over the recessed lights; plastic turns yellow with time.
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.
