Vanities come in a variety of sizes, from just over a foot wide to more than 6 feet wide. Whether you're updating your existing vanity or undergoing a full-on bathroom renovation, making sure you have the right size for your vanity is key to a functional bathroom layout. Follow these four easy steps to find the perfect vanity size for your space.
Standard Bathroom Vanity Sizes
| Width | Depth | Height | |
|---|---|---|---|
| Single-Sink Vanity |
|
|
|
| Double-Sink Vanity |
|
Standard vanities typically can be purchased in these widths:
- 24 inches
- 30 inches
- 36 inches
- 48 inches
- 60 inches
- 72 inches
Standard vanity depths range from 20 to 23 inches, with most averaging 21 inches. However, there are shallow-depth options available for narrower bathrooms.
Standard vanity heights are typically between 30 and 36 inches. When selecting a vanity height, take note of the people in your household who will be using it. Tall adults may require a taller vanity, while children might prefer one less than 30 inches tall.
Single-Sink Bathroom Vanity Sizes
If you're designing a guest bathroom or a small studio bathroom, a single-sink vanity provides all the functionality you need without taking up too much space. Single-sink vanities are typically 24, 30, 36, or 48 inches across, depending on the amount of counter space and storage you'd need. You can even find some as wide as 60 inches.
If your bathroom is too small to accommodate a standard vanity, you can fit a narrow-depth vanity into a corner or install a wall-mounted vanity to free up floor space.
Double-Sink Bathroom Vanity Sizes
Double-sink vanities are available in wider widths, typically between 60 and 72 inches. Even the smaller 60-inch option offers ample counter space and storage for toiletries. If your bathroom measures at least 15 feet or greater in length, width, or both, you should be able to comfortably fit a 60-inch vanity.
His-and-hers sinks are ideal for bathrooms intended for multiple people, such as primary bathrooms and Jack-and-Jill bathrooms.
How to Find the Right Size Vanity
Bathroom vanities aren’t just items you can purchase and hope for the best. From the positioning of your toilet to the depth of your bathroom, there are numerous things to consider before choosing the right vanity for your bathroom. Follow these steps to ensure your vanity checks off all the boxes.
Step 1. Measure the Width of Your Bathroom
Using a tape measure, measure your bathroom from wall to wall to find the width of your space. Make sure to take into account where your bathroom and shower doors swing so they don’t hit your new vanity.
For a single-sink vanity, you’ll need a minimum of 18 inches of space available; for a double-sink, you’ll need at least 48 inches. Keep in mind that the top width of your vanity will be about an inch wider than the bottom width due to the countertop overhang, so be sure to factor that into your decision when choosing a vanity size.
Step 2. Measure the Depth of Your Bathroom
To avoid a cramped bathroom layout, measure from the back wall of your bathroom to the front. Because you'll need room to open your vanity drawers and doors, it's best practice to leave at least 30 inches of floor space between your wall and the front of your vanity.
The most common vanity depths are 20 to 21 inches, though you can find narrow depth options that are only 18 inches.
Step 3. Measure the Height of Your Countertop
The standard vanity height is 30-36 inches, though the height you choose will largely depend on the existing features in your bathroom. To find the right height for your vanity, measure from the floor up to where the countertop would hit your waist.
However, you'll also want to factor in faucet height and other features, like the placement of a backsplash or electrical outlets. There are also shorter vanities available for kids' bathrooms, or you can choose a floating vanity to hang at whatever height you wish.
Step 4. Maintain a Functional Layout
As mentioned in step 1, choosing a vanity that simply fits in your space isn't the only thing to consider. To create a functional bathroom layout:
- Be aware of how much room drawers and cabinets will need to swing or pull out
- Consider how much walking room you'll need in front of your vanity
- Follow regulations by ensuring the center of your toilet is at least 18 inches from the side of the vanity and the tub has a minimum of 30 inches of clearance
Other Important Considerations
Size isn't the only factor when choosing a vanity for your bathroom. Other important considerations include:
- Plumbing: Plumbing placement will dictate the style of vanity you can install and where. For example, most bathrooms have plumbing designed to accommodate a floor-mounted vanity, but if you wanted a wall-mounted vanity, you might have to adjust the plumbing hookups for your sink.
- Faucet type: If you already have your faucet on hand, check that the spout will reach the sink and that the vanity has the correct number of faucet installation holes.
- Scale: If you're keeping any existing mirrors or backsplashes, make sure the width of the vanity you choose is to scale.
- Existing elements: Take note of the current placement of electrical switches and outlets, as well as where the water from your sink will flow from.
