Vanity cabinet don't have to be square and boxy.
The typical dimensions for bathroom vanities—excluding custom sizes—are as follows:
• Depth: A standard vanity is 21 inches deep. There are also vanities as shallow as 18 or even 16 inches. If you are remodeling your bathroom, do not just assume your vanity is 21 inches deep; make sure to measure just in case you are replacing a smaller unit. Also remember that the depth of your vanity will affect what size you can install.
• Height: You won’t find one standard height for vanities, as they usually have a small range of measurements that can accommodate people of various heights. Typically, vanities will be between 31½ to 34½ inches in height. Remember that the height of a vanity is measured before a countertop is placed on top of them, and countertops usually add 1½ inches of height.
• Width: While the height and depth of vanities do not fluctuate too greatly, the width of vanities have a far greater range. The starting point for width usually is 24 inches. Vanity widths usually increase by 3-inch increments. Vanities that are used for a single sink bowl usually range from 24 inches to 48 inches, while vanities that provide enough room for two sinks start at 48 inches.
• Mini Vanities: These smaller vanities are used in bathrooms with a limited amount of space. They have the same height as regular vanities, but are only 16 inches in depth, are usually 18 inches in width.
