Vanity size guide: Find the perfect fit for your bathroom

When you imagine your perfect bathroom interior design, images of a clawfoot tub, intricate tile work, and skylight might come to mind. Among all those bathroom ideas, what probably doesn’t come to mind? The precise width, height, and depth of your bathroom vanity. And yet, the exact vanity measurements affect everything from how much storage you get to whether two people can brush their teeth at the same time. 

In this guide, we’ll walk you through standard vanity sizes and how to choose the right one for your space. Whether you’re working with a cozy half-bath or a spa-like master bathroom, the right vanity makes all the difference. 

Standard bathroom vanity dimensions

Before you pick out a dreamy vanity top with matching fixtures, it helps to know the standard bathroom vanity sizes. Getting the right size — height, width, and depth — is crucial.

Standard vanity height

The standard bathroom vanity height ranges from 30 to 36 inches, with 34 inches often considered the sweet spot. This mid-range height works well in most households, especially in shared spaces or guest bathrooms. 

For taller users, a 36-inch tall bathroom vanity offers more comfort. On the other end, a 30-inch tall bathroom vanity may be better suited for children who need easier access. Don’t forget to factor in the sink style. For instance, a vessel sink adds extra height, so your vanity counters might need to be shorter to keep the overall sink height viable. 

Standard vanity width

Bathroom vanity width has a wider range than vanity height and depends entirely on your bathroom layout and use. A single-sink vanity typically falls between 24 and 48 inches, offering enough counter and cabinet space for small bathrooms. Double vanity options usually start at 60 and go up to 72 inches or more, giving multiple users plenty of counter space to prevent sink-side turf wars. 

Getting the right width ensures your bathroom vanity fits seamlessly between walls, fixtures, and door swings. It also determines how neat your bathroom is. Plenty of countertop space and under-sink storage means your makeup kit, hair dryer, and medicine bottles all have a home. 

Standard vanity depth

Depth and width work together to create the ideal amount of countertop and storage space. Standard bathroom vanity depth usually falls between 18 and 24 inches. Shallow 18-inch vanities are perfect for small bathrooms or tight spaces where every last inch counts. If you have more room, 20 to 24 inches offers more functional space to get ready in the morning and comfortably fill drawers and cabinets with all your bathroom essentials. 

Vanity measurements by type

Bathroom vanity sizes aren’t one-size-fits-all. The right dimensions depend on the ideal configuration and use. Whether it’s a single sink or double vanity each option comes with recommended measurements. Choosing the right one will make all the difference in how comfortable your bathroom is for everyday use. 

Single-sink vanity measurements

Single-sink vanities are a popular pick for small bathrooms, guest bathrooms, and powder rooms. Most models range from 24 to 48 inches wide. Compact works great for powder rooms that only need enough counter space for soap, whereas functional small washrooms and guest bathrooms might want more counter space and storage. Depth typically falls between 18 to 21 inches, while height lands between 30 and 36 inches. 

If you’re working with a narrow layout, look for vanity cabinets on the slimmer end to keep your bathroom feeling open and easy to move through. For a master bathroom, though, choose a model with more generous counter space and pair it with built-in shelving or wall-mounted fixtures to boost storage.

Double-sink vanity dimensions

Busy households and shared spaces benefit from a double-sink vanity. With widths starting at 60 inches and stretching to 72 inches or more, these vanities provide ample room for two sinks, separate drawers, and generous counter space — so you’re not knocking elbows with your roommate. Despite the extra width, double vanities follow the same depth and height rules.

Compact corner vanity measurements

If you need to squeeze a vanity into a tight layout, a space-saving corner vanity is a good fit. These options typically range on the smaller end — 24 to 30 inches in width and 16 to 18 inches deep. While you won’t have sprawling counter space or oversized vanity cabinets, you’ll be able to maximize valuable floor space. 

How to choose the right standard vanity size for your space

Nothing ruins a peaceful morning like elbowing your way around a too-small sink. If you get the vanity size wrong, you’ll notice it every day. Here’s how to make sure your bathroom vanity works for your space and your routine: 

• Measure your available space: Start by measuring the floor area where your vanity will go to better understand width and depth limits. Make sure to leave enough clearance around the vanity — a minimum of 15 inches between the vanity’s edge and the center of the toilet and a minimum of 21 inches of open space in front. 

• Consider door swings and plumbing locations: Make sure your vanity fits comfortably without interfering with door openings or plumbing pipes. Leave enough clearance to prevent awkward bumps and allow access to cabinets and drawers. 

• Match vanity height to the primary user’s comfort: Choose a height that fits whoever uses the vanity the most. Taller folks might want something higher, while shorter users, kids, or people with mobility issues might want a lower setup. 

• Plan for storage needs: Think about what you need to stash away to choose a vanity with enough storage. A floating vanity may fit into a minimalist design aesthetic but fall short of housing daily essentials. 

• Account for mirrors, faucets, and lighting: Your vanity height and size should fit right in with the rest of your interior design. For instance, a ceramic vessel sink might add bohemian flair but will feel uncomfortable perched on a tall vanity.
