The Ideal Size of a Double Sink Vanity

Although the ideal size will vary from person to person, double vanities often start around 48 inches in width and go up to 80 inches or more. For even sink and counter space, getting a vanity that measures 60 to 72 inches in width is preferable, but again that’s a matter of preference.

The wider the vanity is, the more space you will have for both sinks and counter area where you can store items, take care of hygiene, and get ready. If the sinks are right on top of each other, is it beneficial to have them both?

What is the smallest double sink vanity available?

Typically, you will not find a double sink vanity smaller than 48 inches. That’s because even with 16 or 17 inch sinks, any less space would make these vanities non-functional and essentially useless. Some custom installations can be made with other sizes, but you’ll have to talk to your contractor about that. However, if prefabricated vanities are on your list, 48 inches is where they start.

The Benefits of Double Vanities

Double vanities give you room so two people can be in the bathroom simultaneously. You have two sinks and twice the storage, so it’s more convenient for couples and children who share bathrooms, and so forth. These vanities offer more counter space and can even become a focal point of the room. These vanities can also increase property values because most homebuyers see them as high-end assets.

The Drawbacks of Double Sink Vanities

Double vanities do take up more space. They also require additional plumbing to be run for the second sink if you don’t already have one in place, so that can add to your renovation budget. If you choose a vanity that’s too small, you might lose valuable counter space to a sink, which could be counterproductive (pun intended)!

Does a double vanity add home value?

Most homeowners see double vanities as a higher-end item. They are a staple in modern luxury houses, so they immediately give the impression of a more valuable home whenever they’re present. Many families will look for larger bathrooms with double vanities because they want the extra space, even if they’re not buying a luxury home. So yes, this is a great way to add value to the home.

Can you replace a single sink vanity with a double sink?

Yes, you can replace a single vanity with an upgrade to a double vanity. However, you will also need to get a plumber on board to bring in the plumbing for that new sink, either from the wall or by splitting the current plumbing. This will add to the cost of the project significantly, considering that it’s about $450 to $1,800 to install plumbing for a new sink in the bathroom.

Does a double sink vanity need 2 traps?

As long as two sinks have the same drain and the plumbing is done correctly, a double sink vanity can run with a single p-trap connected to the wall plumbing. For those upgrading to a dual sink configuration, this can save a lot of money on plumbing upgrades. However, there may be some instances where you will have to add a second p-trap or reroute plumbing, depending on your current situation.

Can 2 sinks share the same drain?

Sinks cannot share a drain. Although they can eventually connect through the plumbing, each sink will need its own drain to put water down into the pipes in the first place. With separate drains, each sink would be able to function as it should.

How much space do you need between the vanity and the toilet?

Although everyone’s comfort level will vary, the National Kitchen and Bath Association recommends 18 inches of space between the toilet and any other fixtures, including the vanity. More space will give you more room to move and access storage. Codes permit space as small as 15 inches for smaller bathrooms.

Is a double vanity worth it?

Ultimately, whether a double vanity is worth it will depend on your needs. Some people hate sharing a sink, or it’s just not feasible because of schedules, for example. Others might decide to save counter space and use a single sink when they’re limited on vanity space. If you need the extra sink, even when you don’t have room for a huge vanity, there are plenty of styles that will be worth the purchase.
