How to Plan for a Double Sink Bathroom Vanity


Bathroom vanities are an important aspect of any home bathroom — they allow you to wash up and store your beauty products, and the more space the better. Whether you share a bathroom with your spouse, have two kids that need to use the same restroom, or just want allow your guests more than one sink, a double sink vanity is a plus. While not all bathrooms will have the space to accommodate two sinks, installing an extra sink is worth thinking about during a bathroom remodel project. In order to determine if a double sink vanity is right for your bathroom, consider the following factors.


Bathroom vanities can be crowded real estate in your home, particularly if you have a large family. Adding two sinks to the vanity space not only makes it easier for your family to use the space, but can increase the resale value of your home. If the next potential buyer prefers an individual sink in the master bathroom, for example, the fact that you have a dual sink vanity may make or break their decision to purchase your home.


Of course, a small bathroom may not have room for more than one sink in the vanity. Don’t sacrifice function for appearances — if a dual sink set up will make your bathroom too cramped to be comfortable, you’re better off settling for a single sink that looks natural in the room. Determining if you have enough room for a double sink bathroom vanity is easy enough; measure the space available for your vanity and then determine the length of your proposed vanity. Make sure that your shower stall can comfortably swing open with a longer vanity, and that there will still be ample room around the toilet.

Other Measurements

When you are measuring for two sinks, keep in mind that no more than 30 inches should exist between the middle of each sink basin. If there is too much space between each sink, the plumbing aspect of your remodel may be affected adversely. Also, make sure that there is at least one foot of space between the center of each sink and the nearest wall (not including the wall behind the sink). This allows enough space to comfortable wash your hands and stand in front of the sink without banging your elbows.


You can use the same waste line for two sinks, but separate traps and drains are probably required. The set up for bathroom vanities’ plumbing may vary based on the cupboard and drawer set up; in some cases, the drawers will make it more difficult to combine the two sink’s waste lines into one. Consult your plumber during a bathroom remodel to find out the extra costs involved with adding another sink — if it is even possible. If you buy a dual sink vanity and then find out the plumbing requirements are extensive, you may regret your purchase.

Custom Vanities

If your room is small but you’re determined to have a two sink vanity, consider getting a custom vanity built. Custom projects let you get the look you want without having to adhere to the standard sizes in which countertops and bathroom cabinetry are typically sold. Custom bathroom vanities also let you get exactly what you want when it comes to the countertop and cabinetry combinations.
