When planning a bathroom remodel or designing a new one, one of the key decisions you'll make is the size of your vanity. Double vanities, with their two sinks and ample counter space, are a popular choice for master bathrooms and larger powder rooms. But what are the average double vanity dimensions, and how do you choose the right size for your space?
Understanding Double Vanity Dimensions
Double vanities come in a range of sizes, but they typically fall within certain average dimensions. Understanding these averages can help you narrow down your options and ensure you're choosing a vanity that fits your space and your needs.
Average Width
The width of a double vanity is one of the most important dimensions to consider, as it will determine how much space the vanity takes up in your bathroom. On average, double vanities range in width from 60 to 78 inches (5 to 6.5 feet). Here's a breakdown of average widths:

- 60 inches (5 feet): This width is suitable for smaller bathrooms or powder rooms. It typically accommodates two standard undermount sinks.
- 63 inches (5.25 feet): This is a common width for double vanities. It provides enough space for two sinks and some counter space between them.
- 72 inches (6 feet): This width is great for larger bathrooms. It offers plenty of counter space and can accommodate larger sinks or additional features like a built-in drawer or tray.
- 78 inches (6.5 feet): This is the widest average size for a double vanity. It's ideal for spacious bathrooms and can accommodate two large sinks and plenty of counter space.
Average Depth
Depth is another crucial dimension to consider, as it will affect how much space the vanity takes up from the wall to the front of the vanity. On average, double vanities range in depth from 21 to 24 inches (1.75 to 2 feet). Here's a breakdown of average depths:
- 21 inches (1.75 feet): This depth is suitable for smaller bathrooms or powder rooms. It provides enough space for two sinks and some counter space, but may not offer as much storage as deeper vanities.
- 24 inches (2 feet): This is a common depth for double vanities. It offers a good balance between counter space and storage, and can accommodate standard undermount sinks and drawers.
Choosing the Right Double Vanity Dimensions
When choosing the right double vanity dimensions, consider the size of your bathroom and your specific needs. Here are some tips to help you make the right decision:
Measure Your Space
Before you start shopping, measure the width and depth of the space where your vanity will go. This will help you determine the maximum dimensions you can accommodate. Also, consider the height of your plumbing fixtures to ensure your vanity will fit properly.

Consider Your Needs
Think about how you'll use your vanity. If you need plenty of counter space for getting ready in the morning, you might want a wider vanity. If storage is a priority, you might want a deeper vanity with more drawers or cabinets. If you have specific sink or faucet preferences, make sure the vanity you choose can accommodate them.
Think About Scale
In addition to measuring your space, consider the scale of your bathroom. A large vanity in a small bathroom can overwhelm the space, while a small vanity in a large bathroom can look out of place. Choose a vanity that's appropriately sized for your bathroom to create a balanced, harmonious look.

Remember, these are just averages. Double vanities can come in a wide range of sizes, so don't be afraid to look for something custom if you can't find what you need off the shelf. With the right dimensions, you can find a double vanity that fits your space and your lifestyle perfectly.
