Choosing a bathroom vanity is about much more than finding a cabinet that looks good. The right vanity needs to fit your bathroom, provide practical storage, work with your existing plumbing, accommodate the right sink and countertop, and make your daily routine easier.

A vanity that is too large can make a bathroom feel cramped. One that is too small may leave you without enough counter space or storage. And choosing the wrong configuration can create installation problems that you may not discover until the vanity arrives.

Whether you're renovating a powder room, family bathroom or primary ensuite, here are 12 important things to consider before buying a bathroom vanity.

1. Measure Your Bathroom Before Choosing a Vanity

Start with the space—not the style.

Measure the available:

• Width

• Depth

• Height

• Distance to nearby walls

• Distance to the toilet, tub and shower

• Door and drawer clearance

Don't simply measure the old vanity and assume the same dimensions will work.

Open the bathroom door and shower door while measuring. Think about how cabinet doors and drawers will open once the new vanity is installed.

Also check the locations of:

• Plumbing

• Electrical outlets

• Light switches

• Mirrors and medicine cabinets

• Baseboards and trim

A beautiful vanity isn't a good choice if its drawers collide with a wall or its countertop interferes with the bathroom door.

Quick Tip: Mark the vanity dimensions on the floor with painter's tape. This gives you a much better idea of how much space the vanity will actually occupy.

2. Choose the Right Vanity Width

Bathroom vanities are available in many widths, but several sizes are particularly common.

24 Inch Vanities –30 Inch Vanities

Best for:

• Powder rooms

• Condos

• Small bathrooms

• Guest bathrooms

A compact vanity provides essential sink and storage space without overwhelming a smaller room.

36 Inch Vanities

A 36-inch bathroom vanity offers a useful balance between storage and floor space. It's a popular option for smaller full bathrooms where a 24- or 30-inch vanity may feel too limited.

48 Inch Vanities

A 48-inch bathroom vanity provides considerably more counter and storage space while still fitting comfortably into many medium-sized bathrooms.

It's an excellent choice for:

• Family bathrooms

• Guest bathrooms

• Smaller primary bathrooms

60 Inch Vanities

A 60-inch bathroom vanity works particularly well in larger bathrooms and is one of the most popular sizes when homeowners are considering a double-sink configuration.

It can provide generous drawer storage and enough countertop space for two people to use the bathroom more comfortably.

72 Inch and Larger Vanities

For spacious primary bathrooms, larger vanities can create a substantial focal point while providing extensive storage and countertop space.

But bigger isn't automatically better. Always preserve comfortable movement around the room.

3. Don't Forget Vanity Depth

Width gets most of the attention, but depth can be just as important.

Many standard bathroom vanities are approximately 17 to 24 inches deep, depending on the design.

In a narrow bathroom, even a few extra inches can affect how easily you can move through the space.

If your bathroom has limited floor space, consider:

• A shallower vanity

• A compact vanity

• A wall-mounted vanity

• A narrower sink configuration

For larger bathrooms, a deeper vanity can provide additional counter and storage space.

Always check the manufacturer's exact dimensions rather than assuming that every vanity of the same width has the same depth.

4. Choose a Comfortable Vanity Height

Bathroom vanity height affects how comfortable the sink is to use every day.

Vanities are commonly found in approximately the 30-to-36-inch height range, although exact dimensions vary by model.

A taller, comfort-height vanity can reduce the need for many adults to bend forward while using the sink.

However, the cabinet height isn't the only measurement that matters.

If you're installing a vessel sink, the basin sits above the countertop and increases the total sink height. In that situation, a lower vanity cabinet may provide a more comfortable finished height.

Think about who will use the bathroom most often before choosing.

5. Decide Between a Single and Double Sink

More sinks don't always mean a better bathroom.

Choose a Single-Sink Vanity If:

• The bathroom is relatively small

• One person usually uses it at a time

• Storage is a priority

• You want maximum countertop space

• You don't want to modify existing plumbing

A single sink often leaves more room for drawers and usable counter space.

Choose a Double-Sink Vanity If:

• Two people regularly get ready at the same time

• You have sufficient vanity width

• The bathroom has enough room around the vanity

• The plumbing can accommodate two sinks

Double sinks can be extremely convenient in shared primary and family bathrooms.

But ask yourself a practical question before choosing one:

Would you rather have two sinks—or one sink with more counter space and storage?

For some households, the second option is actually more useful.

6. Check Your Plumbing Before You Buy

This is one of the most commonly overlooked steps.

Before ordering a vanity, check where your:

• Water supply lines

• Drain

• P-trap

• Shut-off valves

are located.

Then compare those locations with the interior configuration of the vanity.

A vanity with multiple full-depth drawers may look perfect online but could interfere with existing plumbing.

Wall-mounted vanities require even more planning because both the plumbing and wall structure may affect installation.

Keeping the new vanity close to the existing plumbing configuration can often make installation simpler. If you're substantially changing the vanity position or sink configuration, consult a qualified plumber before ordering.

7. Think About Storage Before Style

A beautiful bathroom can quickly look cluttered when there isn't enough storage.

Before shopping, make a rough list of what you actually keep in the bathroom:

• Towels

• Toiletries

• Hair dryers

• Styling tools

• Skincare products

• Makeup

• Cleaning products

• Toilet paper

• Personal-care products

Then choose the storage configuration accordingly.

Drawers

Drawers make frequently used smaller items easier to see and access.

They're especially useful for:

• Cosmetics

• Grooming products

• Hair accessories

• Small toiletries

Cabinets

Cabinets are better for taller or bulkier items.

Combination Storage

For many households, the most practical vanity combines drawers and cabinet space.

Don't judge storage capacity only by the exterior size of the vanity. Sink bowls and plumbing can take up significant interior space, so inspect the actual drawer and cabinet configuration.

8. Wall-Mounted or Freestanding Vanity?

Both styles can work beautifully, but they create very different looks.

Wall-Mounted Bathroom Vanities

Also called floating bathroom vanities, these units are mounted above the floor.

They are popular in contemporary bathrooms because they create clean visual lines and expose more flooring, which can help a smaller bathroom feel more open.

They also make the floor underneath easier to access for cleaning.

Floating vanities work particularly well in:

• Modern bathrooms

• Condos

• Minimalist interiors

• Smaller bathrooms

Installation needs to be properly planned because the wall must support the vanity.

Freestanding Bathroom Vanities

Freestanding vanities sit on the floor and are secured appropriately during installation.

They can suit:

• Traditional bathrooms

• Transitional designs

• Modern interiors

• Larger family bathrooms

They're available in everything from furniture-inspired designs to streamlined contemporary styles.

The best choice isn't simply about appearance. Consider installation, storage, cleaning and the overall architecture of your bathroom.

9. Choose Materials Made for Bathroom Conditions

Bathrooms experience moisture, humidity, splashes and frequent cleaning, so material quality matters.

Bathroom vanity cabinets may be constructed from materials such as:

• Solid wood

• Plywood

• MDF

• Engineered wood

• Other moisture-resistant composite materials

No material should be judged by its name alone. Construction quality, finishing, sealing and manufacturing quality also affect how a vanity performs over time.

Pay particular attention to:

• Finished edges

• Cabinet construction

• Drawer construction

• Hardware quality

• Moisture protection

• Surface durability

If you're comparing two similar-looking vanities, look beyond the exterior finish and compare how they're actually constructed.

10. Select the Right Countertop

Your vanity countertop has to handle water, soap, cosmetics, cleaning products and everyday wear.

Popular options include:

Quartz

Quartz is popular because it combines a premium appearance with relatively easy maintenance.

Natural Stone

Marble and granite can create a distinctive high-end look because every slab has natural variation. Some natural stones require periodic sealing and additional care.

Engineered and Integrated Tops

Many ready-to-install vanities include a coordinated countertop and sink, simplifying the selection process.

Whatever material you choose, consider:

• Water resistance

• Stain resistance

• Cleaning requirements

• Maintenance

• Colour

• Veining

• Edge profile

• Sink compatibility

For a busy household, practical maintenance may be just as important as appearance.

11. Check the Sink and Faucet Configuration

Don't order your faucet until you know what the vanity top supports.

Bathroom vanity tops may be designed for:

• Single-hole faucets

• Centerset faucets

• Widespread faucets

• Vessel sinks

• Undermount sinks

• Integrated sinks

The sink itself also affects usable countertop and cabinet space.

An undermount sink creates a clean transition between the countertop and basin, while a vessel sink becomes a stronger visual feature.

Before buying, confirm:

Vanity + countertop + sink + faucet compatibility.

Treat these four components as one system rather than four separate purchases.

12. Think About Cleaning and Long-Term Use

Design decisions that look insignificant in a showroom can make a major difference after several years of daily use.

Ask:

• Is the countertop easy to wipe clean?

• Can I easily clean around the sink?

• Is there enough clearance around the vanity?

• Are the drawers easy to access?

• Are there difficult-to-clean gaps?

• Will the finish show fingerprints or water spots?

• Can I reach the floor underneath?

• Is the storage configuration practical?

For busy households, features such as soft-close drawers and doors can also improve everyday usability.

The best vanity isn't necessarily the most dramatic one. It's the one that continues to work well after the excitement of the renovation is over.

Common Bathroom Vanity Buying Mistakes

Even a high-quality vanity can become the wrong purchase if it doesn't work with the room.

Avoid these common mistakes:

Buying before measuring
Never rely on photos to judge scale.

Ignoring vanity depth
A vanity may fit the wall but extend too far into the walkway.

Forgetting door clearance
Check bathroom, shower and vanity doors.

Ignoring plumbing locations
Drawer and cabinet configurations can conflict with drains and water lines.

Choosing two sinks automatically
Sometimes one sink plus additional storage is more useful.

Choosing appearance over storage
Think about what you need to store before deciding on the cabinet configuration.

Forgetting faucet compatibility
Confirm the number and spacing of faucet holes before purchasing the faucet.

Ignoring finished height
This is particularly important when using a vessel sink.

Bathroom Vanity Size Quick Guide

Vanity Width	Best For	Typical Configuration
24"	Powder rooms, very small bathrooms	Single sink
30"	Small bathrooms, condos	Single sink
36"	Small to medium bathrooms	Single sink
48"	Medium bathrooms	Single sink / select double configurations
60"	Primary and shared bathrooms	Single or double sink
72"+	Large primary bathrooms	Double sink

These are general guidelines rather than strict rules. Always check the exact dimensions and specifications of the vanity you're considering.

Frequently Asked Questions

What size bathroom vanity should I choose?

Choose the largest vanity that provides the storage and counter space you need without restricting comfortable movement through the bathroom. Common widths include 24, 30, 36, 48 and 60 inches, with larger options available for spacious bathrooms.

Is a 36-inch vanity big enough?

A 36-inch vanity can be an excellent choice for a small or medium bathroom. It provides more countertop and storage space than compact 24- or 30-inch models without requiring the footprint of a 48-inch vanity.

Is a 48-inch vanity a good size?

Yes. A 48-inch bathroom vanity is a versatile option for medium-sized bathrooms and can provide generous counter and storage space while remaining more compact than a 60-inch vanity.

What size vanity is best for two sinks?

A 60-inch bathroom vanity is a common starting point for double-sink configurations, although the exact amount of usable space depends on sink size, cabinet design and plumbing. Always check the product specifications rather than relying on width alone.

Are floating bathroom vanities good for small bathrooms?

They can be. Because a floating vanity exposes more of the floor, it can make a compact bathroom feel visually lighter and more open. The space underneath is also easier to access for cleaning.

Should I choose drawers or cabinets?

For most bathrooms, a combination works well. Drawers provide convenient access to smaller everyday products, while cabinets accommodate taller and bulkier items.

Should I choose the vanity or faucet first?

Plan them together. The countertop determines which faucet configurations can be installed, while the sink type affects both faucet placement and available counter space.

Final Thoughts

A bathroom vanity is one of the hardest-working pieces in your bathroom. It serves as storage, countertop, sink station and a major design feature—all at the same time.

That's why the best vanity isn't simply the one that looks best in a photo.

Start with measurements and plumbing, determine how much storage and counter space you actually need, decide between single and double sinks, and then choose the materials, colour and style.

When function comes first, it's much easier to find a vanity that looks beautiful and works beautifully too.
