1. The main styles of medicine cabinets and vanity sets are modern or contemporary, traditional, shaker/mission, and cottage. Choose your medicine cabinet based on what style of vanity you've chosen, as this is the piece of furniture to which it will be closest.

2. Contemporary style begins with the designs of the 1920s Art Deco movement all the way through the creations of today. This style is simple and clean, and features little or no details. Contemporary pieces are a great addition to your bathroom when you're replacing existing vanities and medicine cabinets.

3. Traditional vanities are typically influenced by the Far East or European countries. A few examples of these styles are the French provincial, British Colonial, and Chippendale designs.

4. Consider designing your bathroom in the shaker/mission style if functional and plain design with an emphasis on quality and natural beauty is what you crave.

5. Cottage is more of a casual design that is comfortable and wears well.

6. Once you find the style that is most appealing to you, begin to look at the space options in your bathroom, and then begin the fun of finding the furniture styles that are right for it!
