When it comes to bathroom remodeling or renovation, one of the most important decisions you’ll make is choosing the right vanity. The vanity is not only a functional element, but also a design statement. In this article, we’ll explore the standard bath vanity sizes to help you make an informed decision.

Why Standard Sizes Matter

Before we dive into specific sizes, it’s important to understand why standard sizes matter. Standard sizes are established to ensure that bathroom fixtures and fittings are compatible with each other. This means that if you choose a standard size vanity, you’ll have an easier time finding the right sink, faucet, and other accessories.

Single Sink Vanities

Single sink vanities are the most common type of vanity. They are available in widths ranging from 24 inches to 36 inches. A 24-inch vanity is ideal for small bathrooms or powder rooms, while a 36-inch vanity offers more counter space and storage.

Double Sink Vanities

Double sink vanities are a great option for larger bathrooms or shared spaces. They are available in widths ranging from 48 inches to 72 inches. A 48-inch vanity is suitable for a smaller shared bathroom, while a 72-inch vanity offers ample space for two people to get ready at the same time.

Floating Vanities

Floating vanities are a popular choice for modern bathrooms. They are mounted on the wall, giving the illusion of more space. Floating vanities are available in various sizes, ranging from 24 inches to 72 inches.

Corner Vanities

Corner vanities are a space-saving option for smaller bathrooms. They are available in widths ranging from 24 inches to 36 inches. A corner vanity can be a great solution for a bathroom with an awkward layout.

Custom Vanities

If you have a unique bathroom layout or specific design requirements, a custom vanity may be the best option for you. A custom vanity can be made to your exact specifications, ensuring a perfect fit and seamless integration with your bathroom design.

Vanity Depth

In addition to width, vanity depth is also an important consideration. The standard depth for a vanity is between 18 inches and 21 inches. However, some vanities may be shallower or deeper depending on the style and design.


Choosing the right vanity size is an important part of any bathroom remodeling project. Standard sizes ensure compatibility with other bathroom fixtures and fittings, while custom options allow for a perfect fit. By considering your bathroom size, layout, and design preferences, you can select a vanity that enhances both the functionality and aesthetic of your space.
