Choosing the right bathroom vanity can make your space feel more organized, stylish, and practical. But should you go with a single vanity or a double vanity? It’s a big decision, especially if you’re remodeling or building a bathroom from scratch.
Let’s break it down in simple terms so you can decide which type of vanity works best for your space, your family, and your daily routine.
Understanding the Basics: Single and Double Vanities
What Is a Single Vanity?
A single vanity has one sink and is usually between 24 to 48 inches wide. It fits best in small bathrooms, guest bathrooms, or powder rooms. These vanities are great if only one person is using the space at a time. They often have a good mix of counter space and cabinet storage below the sink.
What Is a Double Vanity?
A double vanity has two sinks and is usually 60 to 72 inches wide. It’s a popular choice for master bathrooms or any space shared by two people. You get two sinks, more countertop room, and extra drawer space. It’s perfect for busy mornings when two people need to get ready at the same time.
Space Requirements and Room Size
Before you pick a vanity, take out your measuring tape! Here’s what to keep in mind:
- If your bathroom is small (under 50 square feet), a single vanity is usually the best fit.
- If you have more room (over 60 square feet), you might be able to fit a double vanity comfortably.
- You’ll also need to leave space for opening cabinet doors, walking around, and using the sink without bumping elbows.
Remember, it’s not just about squeezing a vanity in—it’s about making the space comfortable and functional.
User Needs and Daily Functionality
Think about who uses the bathroom and how they use it.
- If it’s mostly for guests or one person, a single vanity is simple and practical.
- If it’s a shared space—like a couple’s or family bathroom—a double vanity can be a lifesaver.
No more fighting for sink time in the morning! With two sinks, everyone gets their own space, and mornings run a little smoother.
Storage Capacity and Counter Space
Storage matters! With a double vanity, you usually get more drawers and under-sink cabinets. This helps keep the bathroom tidy and gives you room for:
- Towels
- Hair tools
- Cleaning supplies
- Extra toilet paper
That said, single vanities can still offer ample storage—especially if you choose one with tall drawers or pair it with upper cabinets or shelving.
Installation and Plumbing Considerations
Here’s something important: installing a double vanity often means adding extra plumbing. That can increase the cost and time it takes to remodel. If your bathroom already has plumbing for just one sink, sticking with a single vanity will be faster and more affordable.
On the other hand, if you’re already planning a full renovation, it may be worth the effort to switch to a double vanity—especially if you’ll use the extra space every day.
Cost Comparison
Generally speaking, double vanities cost more than single vanities. Why?
- More materials (extra sink, bigger countertop)
- More plumbing work
- Larger cabinets
If you’re working with a budget, a single vanity is a smart, cost-effective choice. But if you’re going for comfort and convenience in a shared space, the added cost of a double vanity might be worth it.
Design Styles and Aesthetic Appeal
Both single and double vanities come in many styles—modern, traditional, floating, and even furniture-style designs.
- A single vanity in a small bathroom can help create a clean, open look with sleek lines.
- A double vanity adds symmetry and balance to a large bathroom, especially if paired with matching mirrors and lighting.
Whatever your style, there’s a vanity that fits. Just match the vanity design to your overall bathroom layout and color scheme.
When to Choose Each: Quick Summary Guide
Here’s a helpful way to decide:
Choose a single vanity if:
- Your bathroom is under 60 square feet
- Only one person uses the bathroom
- You’re on a tighter budget
- You want a simple, quick installation
Choose a double vanity if:
- You share the bathroom with someone else
- You have enough space for at least 60 inches of vanity
- You need more storage and counter space
- You want to boost comfort and convenience
Smart Style Starts with the Right Vanity
Whether you go with a single or double bathroom vanity, the right choice depends on your space, routine, and remodeling goals. Make sure to measure carefully, think about who uses the bathroom, and picture how you want the space to feel.

FAQ: Choosing the Right Vanity, Sink, and Fixtures for Your Bathroom
What Are the Standard Bathroom Vanity Sizes and Dimensions?
Bathroom vanities come in an array of sizes to fit everything from compact bathrooms to larger bathroom layouts. Standard vanity dimensions usually fall into these common categories:
- Width: Ranges from 24″, 30″, 36″, 48″, 60″, up to 72″
- Single vanities: 24″–48″ wide
- Double vanities: 60″–72″ wide or more
- Depth: Most vanities are 18″–21″ deep
- Height: Standard height is around 32″–36″, known as “comfort height”
Freestanding vanities and wall-mounted vanities are available in both custom and stock sizes, making it easier to find the perfect vanity for your space. If you’re dealing with tight space, a corner vanity is a smart choice. For tall users or those with mobility needs, consider adjustable shelves and comfort-height designs.
No matter your layout, there’s a bathroom vanity out there that fits your personal style preferences and functional needs.
What is a Bathroom Vanity?
A bathroom vanity is more than just a cabinet. It’s a functional centerpiece that combines a sink, countertop, and storage space into one stylish unit. A vanity also helps to conceal plumbing, organize bathroom essentials, and support daily routines.
Vanities can come as:
- Freestanding units with legs or bases
- Wall-mounted vanities that float above the floor
- Corner vanities for small, awkward spaces
You can choose from modern bathroom vanities with clean lines or traditional vanities with ornate finishes. Most come with a vanity countertop, which supports sinks like drop-in sinks, vessel sinks, or undermount sinks. Many also include closed cabinets, built-in shelves, and room for vanity lighting and a bathroom mirror.
The right vanity enhances your bathroom design by adding functionality, style, and storage—making it a must-have in any remodel or upgrade.
What is the Best Shape for a Sink?
The best sink shape depends on your bathroom layout, personal preferences, and design aesthetic. Some of the most popular sink shapes and styles include:
- Oval or round: Soft, classic look—ideal for traditional bathroom vanities
- Rectangular or square: Sleek and modern, fits well in modern vanities
- Vessel sinks: Sit on top of the counter and offer a touch of elegance
- Pedestal sinks: Space-saving but limited storage—often used in powder rooms
Each has practical benefits. For example, rectangular sinks offer more countertop space around the basin, while oval sinks can feel more traditional. The key is matching the shape with the size of your bath vanity and how it’s used.
Whether you’re after a stylish solution or a practical one, the right sink shape can enhance both function and beauty.
Will My Sink Fit My Vanity?
Not all sinks are created equal, and it’s important to ensure your sink and vanity are compatible. Here’s what to consider when matching the two:
- Vanity countertop size: Check the width and depth to ensure the sink doesn’t overhang
- Sink style: For drop-in sinks, you need a countertop with a cutout; vessel sinks sit on top
- Cabinet layout: Make sure there’s space below for plumbing
- Faucet placement: Some sinks require wall-mounted faucets or specific spacing
Always review manufacturer specs and consult a vanity dimensions chart. For custom vanity builds, a sink can be tailored to fit perfectly. If you’re working with a pre-made unit, choose a sink style recommended for that model.
Getting the fit right is key to avoiding leaks, damage, or awkward layouts.
What is the Standard Bathroom Sink Size?
Most bathroom sinks are designed to fit standard vanity sizes. A typical sink measures:
- Width: 16″–20″ side to side
- Length (front to back): 12″–24″
- Depth: 5″–8″
This gives enough functional space to wash hands and face without taking up too much floor space. For double sink bathroom vanities, each sink should have at least 30 inches of space to allow for ample space between them.
If you’re installing a single sink vanity, a smaller bowl can provide more countertop space, which is great for storing toiletries or decorative items. Vessel sinks may appear taller, so consider vanity height when choosing that style.
Choosing a sink with the right proportions ensures your bathroom vanity is as useful as it is attractive.
Where Do I Mount My Faucet?
Mounting your faucet in the right location is key to making your sink and vanity both functional and stylish. Where you mount it depends on your sink style and vanity countertop configuration:
- Deck-mounted faucets – These are installed directly on the vanity or sink. Common with drop-in sinks, undermount sinks, and pedestal sinks.
- Wall-mounted faucets – These are attached to the wall above the sink and work best with vessel sinks or shallow vanity countertops.
For deck-mounted options, ensure:
- The faucet holes line up with the sink basin.
- There’s enough space for the handle(s) to move freely.
- You measure for proper clearance from the backsplash and bathroom mirror.
If your faucet is too far forward or too close to the wall, it could lead to splashing or limited access. Always measure before installing and follow manufacturer guidelines for best results.
How Many Sinks Do I Need?
This depends on how many people use the bathroom and how often.
- Single sink vanities are ideal for compact bathrooms, guest bathrooms, or smaller households. They save space and cost less to install.
- Double sink vanities are best for larger bathrooms, such as master suites or shared bathrooms. With double sinks, two people can get ready at once, which is a major plus in busy homes.
Ask yourself:
- Do multiple people use the bathroom at the same time?
- Is the available floor space more than 60 inches wide?
- Do you want more storage space and countertop space?
If yes, a double sink vanity might be the perfect solution. If not, stick with a single vanity for a simpler, space-saving setup.
What Kind of Drain Do I Need for My Sink?
The type of drain you need depends on the kind of sink and faucet you choose. Here are the most common:
- Pop-up drain – Standard for most sinks; works with a lever behind the faucet.
- Grid drain – Ideal for vessel sinks without an overflow; allows water to drain constantly.
- Lift-and-turn drain – Twists open and closed; simple and reliable.
When shopping for a drain:
- Match the drain size to the sink’s drain hole (usually 1.25″–1.5″)
- Make sure the drain works with or without an overflow hole, depending on your bathroom vanity sink
Using the wrong drain can lead to leaks or slow drainage. If you’re unsure, consult a bathroom design professional or plumber.
What Is a Double Vanity?
A double vanity features two sinks set into a single vanity countertop. These units are usually 60″ to 72″ wide and provide ample space for couples or families to get ready together.
Benefits of double sink bathroom vanities:
- Two people can use the vanity at the same time
- More storage space with added drawers and closed cabinets
- Helps reduce morning traffic in shared bathrooms
- Adds a touch of elegance and balance in larger bathrooms
Double vanities are available in a variety of styles, including modern, traditional, and transitional vanities. You’ll also find freestanding vanities and wall-mounted vanities with double sink setups. They are considered an excellent option for master suites or high-traffic family bathrooms.
What Is a Single Vanity?
A single vanity is a bathroom vanity with just one sink. It typically ranges from 24″ to 48″ wide, making it ideal for small spaces or homes with only one user.
Benefits of single sink bathroom vanities:
- Compact and budget-friendly
- Easier to install with less plumbing
- Provides plenty of counter space for one person
- Available in freestanding, wall-mounted, or corner vanity styles
Single bathroom vanities are a smart choice for powder rooms, guest bathrooms, or anyone who wants to save space while keeping things stylish. Many models offer drawers, vanity legs, and even built-in medicine cabinets for extra storage.
Despite their smaller size, these vanities come in a wide range of design styles, from rustic wood finishes to clean-lined modern designs, ensuring they fit any design aesthetic or personal preference.
