Depending on the finish, white (or black) cabinets can be wiped down. Finding a finish that won't crack or peel in a wet area, such as the bathroom, should be your first priority. Painted cabinets can always be re-painted or re-touched. Stained cabinets can also be re-stained or painted. Laminate, however, will likely peel in a bathroom in 5-7 years. Your best option is to find a solid-wood door & drawer construction with a stain or painted finish.

Regarding quality cabinets, you will want to find a semi-custom cabinet company that displays these qualities: Solid wood & Particle board construction, dovetail joinery, and heavy-duty drawer glides and hinges.
