Choosing a bathroom vanity looks simple until you actually start shopping.

You find a vanity you love, choose a colour, check the width and place the order. At least, that's how many homeowners expect the process to work.

In practice, there is much more to consider.

At CC Supply, one thing we've learned from helping customers shop for bathroom vanities is that the best-looking vanity isn't always the best vanity for the bathroom.

A few inches of extra depth can make a narrow bathroom uncomfortable. A beautiful drawer configuration can conflict with existing plumbing. Two sinks can sound better than one until you realize how much countertop and storage space they take away.

So before focusing on colour and style, we recommend getting the practical decisions right first.

Here are the things we believe matter most when choosing a bathroom vanity.

1. Start With the Bathroom, Not the Vanity

This is probably the most important advice we can give.

Don't start by asking:

“Which vanity do I like?”

Start by asking:

“What vanity actually works in this bathroom?”

Measure the available width, but don't stop there.

Check:

• Available wall width
• Vanity depth
• Vanity height
• Distance from the toilet
• Bathroom door swing
• Shower door clearance
• Drawer clearance
• Plumbing location
• Electrical outlets
• Light switches
• Mirror position
• Baseboards and trim

We've seen why this matters: a vanity can technically fit against a wall and still be too large for the room.

For example, moving from a 36-inch to a 48-inch vanity may give you more storage, but those additional 12 inches aren't valuable if they make the bathroom uncomfortable to move through.

A Simple Trick We Recommend

Use painter's tape to mark the vanity footprint directly on your bathroom floor.

Don't just look at it.

Walk around it.

Open the bathroom door. Open the shower door. Stand in front of the toilet. Imagine pulling the vanity drawers completely open.

It takes five minutes and gives you a much better sense of the actual size.

2. Width Gets Attention. Depth Causes Problems.

Customers naturally shop by width:

24 inch.

30 inch.

36 inch.

48 inch.

60 inch.

72 inch.

But depth is one of the measurements we think homeowners should pay much more attention to.

Two vanities with the same width can feel completely different in the same bathroom if one projects farther into the room.

This becomes especially important in:

• Condos
• Powder rooms
• Narrow bathrooms
• Bathrooms with a toilet opposite the vanity
• Bathrooms with inward-opening doors

If space is tight, consider a shallower vanity or a wall-mounted bathroom vanity.

Sometimes preserving several inches of walking space improves the bathroom more than gaining several inches of cabinet space.

3. Bigger Isn't Automatically Better

A common instinct during a renovation is to install the largest vanity the room can accommodate.

We don't always think that's the best approach.

The vanity should feel proportional to the bathroom.

A large vanity can provide fantastic storage, but it can also visually dominate a small room.

On the other hand, putting a tiny vanity on a long wall in a spacious primary bathroom can make the room feel unfinished.

As a starting point:

Vanity Width	Often Works Well For
24"	Powder rooms and compact bathrooms
30"	Small bathrooms
36"	Small-to-medium bathrooms
48"	Medium bathrooms
60"	Larger or shared bathrooms
72"+	Spacious primary bathrooms

These aren't rules. Bathroom layout matters more than the number on the product page.

If you're considering one of the most versatile sizes, our 36 inch bathroom vanity collection is a useful place to compare how different cabinet configurations use the same overall width.

4. Decide What You Actually Need to Store

This is another lesson that becomes obvious after living with a bathroom rather than simply designing one.

Beautiful open shelving looks great when it contains three perfectly folded towels.

Real bathrooms contain:

• Toothpaste
• Skincare products
• Hair dryers
• Brushes
• Makeup
• Cleaning products
• Toilet paper
• Medication
• Extra soap
• Towels
• Grooming products
• Dozens of small items

Before choosing your vanity, take a quick inventory of what you currently keep in your bathroom.

Then ask yourself:

Where will all of this go?

Drawers vs. Cabinets

For everyday products, we generally like drawers because they make smaller items much easier to access.

Deep cabinets are useful for larger products, but small toiletries can quickly disappear at the back.

For many households, the most practical setup is a combination:

Drawers for small everyday items + cabinet space for larger items.

Don't judge storage from the outside of the vanity either.

Open the product specifications and look at the internal layout.

The sink, drain and plumbing all consume space.

5. Check the Plumbing Before Falling in Love With the Drawers

This is one of those details that doesn't seem important until installation day.

Imagine buying a vanity with beautiful full-width centre drawers.

Then the installer discovers that your drain runs directly through the space those drawers need.

Now you have three choices:

Modify the vanity.

Move the plumbing.

Return the vanity.

None is ideal.

Before ordering, identify the location of:

• Drain
• P-trap
• Hot-water line
• Cold-water line
• Shut-off valves

Then compare those measurements with the vanity's internal configuration.

If you're replacing an existing vanity and want to keep renovation costs and complexity under control, choosing a new vanity compatible with the existing plumbing can make the project considerably easier.

6. Don't Automatically Choose Two Sinks

This surprises some homeowners.

If you have enough space for a double vanity, should you install two sinks?

Maybe.

But first ask:

How often will two people actually use the sinks at exactly the same time?

Every additional sink consumes:

• Countertop space
• Cabinet space
• Plumbing space

For couples who regularly get ready together, two sinks can be extremely convenient.

But some homeowners may get more everyday value from one sink plus a large uninterrupted countertop and additional drawers.

For larger shared bathrooms, a 60 inch bathroom vanity can give you more flexibility when considering single- and double-sink layouts.

The decision shouldn't simply be:

One sink vs. two sinks.

It should be:

Two sinks vs. everything else I could do with that space.

7. Floating or Freestanding? Think Beyond Appearance

This is partly a design decision—but not entirely.

Floating Bathroom Vanity

A floating vanity attaches to the wall and leaves visible floor underneath.

We particularly like this approach in smaller contemporary bathrooms because exposing more flooring can make the room feel visually lighter.

Another practical advantage is cleaning. When there is sufficient clearance underneath, you can access the floor without working around vanity legs.

Explore our floating bathroom vanities if you're considering this look.

But installation matters. The wall must properly support the vanity.

Freestanding Bathroom Vanity

Freestanding vanities sit on the floor and can provide a more furniture-like appearance.

They're extremely versatile and can work in:

• Modern bathrooms
• Transitional bathrooms
• Traditional bathrooms
• Family bathrooms
• Primary ensuites

Don't choose between the two based solely on what's trending.

Think about your wall construction, cleaning preferences, storage requirements and the overall character of the bathroom.

8. Think About Who Uses the Bathroom

A vanity for a powder room and a vanity for a family bathroom shouldn't necessarily be selected the same way.

Powder Room

Storage may be relatively unimportant.

You can prioritize appearance and compact dimensions.

Kids' Bathroom

Storage and durability become much more important.

Easy-to-clean surfaces are valuable too.

Guest Bathroom

You probably need enough storage for basic essentials without designing the entire room around maximum capacity.

Primary Bathroom

This is where daily routines matter most.

Think about:

• Number of users
• Makeup and grooming
• Hair appliances
• Towels
• Counter space
• Number of sinks
• Electrical access

The question we recommend asking is:

“What happens in this bathroom every morning?”

Design around that answer.

9. Countertop Material Matters More Than Colour

It's easy to choose a countertop based on the sample that looks best.

But bathrooms are wet environments.

Countertops regularly encounter:

• Water
• Toothpaste
• Cosmetics
• Soap
• Hair products
• Cleaning products

So maintenance matters.

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

Natural stones such as marble can be beautiful, but some natural stone surfaces require additional care and periodic sealing.

Whatever material you're considering, ask:

How will this look after years of everyday use—not just on installation day?

That question changes how you evaluate materials.

10. Choose the Sink and Vanity Together

We don't recommend treating the vanity, countertop, sink and faucet as four independent purchases.

They're a system.

Vanity → Countertop → Sink → Faucet → Plumbing

Change one component and it can affect the others.

For example, vessel sinks sit above the countertop.

That means you need to consider the total finished sink height—not simply cabinet height.

An undermount sink behaves differently because the basin sits below the countertop.

Sink dimensions also affect storage underneath.

Before ordering, confirm:

• Sink type
• Sink dimensions
• Faucet-hole configuration
• Faucet height
• Faucet reach
• Cabinet clearance
• Plumbing compatibility

This is especially important when combining products from different manufacturers.

11. Faucet Reach Is a Small Detail With a Big Impact

People often focus on faucet style and finish:

Chrome?

Matte black?

Brushed gold?

But geometry matters more than colour.

The water stream needs to land comfortably inside the basin.

A faucet with insufficient reach can make washing your hands awkward. An inappropriate combination of faucet height, water pressure and basin shape can also contribute to splashing.

So don't buy a faucet simply because it looks good beside the vanity.

Check:

Height + reach + sink position + basin depth.

12. Don't Forget the Mirror

Vanity selection affects what happens above the countertop too.

Before ordering, think about:

• Mirror width
• Mirror height
• Faucet height
• Backsplash
• Wall sconces
• Electrical outlets
• Medicine cabinets

We've seen bathroom plans where every individual item looks great but the dimensions don't work together.

For example, a wider vanity may require a different mirror. A tall vessel faucet may affect mirror placement. Wall sconces may restrict how wide the mirror can be.

Plan the entire wall—not just the cabinet.

13. Soft-Close Drawers Are More Than a Luxury Feature

If you're comparing similar vanities, pay attention to the hardware.

Features like soft-close drawers and doors may not seem exciting when you're shopping, but they're something you interact with every day.

Also check:

• Drawer slides
• Hinges
• Drawer depth
• Interior finish
• Handles and pulls

A bathroom vanity is essentially a piece of furniture that may be opened and closed thousands of times.

Hardware quality matters.

14. Think About Cleaning Before Buying

One question we think deserves more attention is:

How difficult will this vanity be to clean?

Look at:

• Space underneath
• Cabinet legs
• Sink edges
• Countertop seams
• Handles
• Areas around the faucet
• Gaps between the vanity and wall

Highly decorative designs may create more areas where dust and moisture collect.

There's nothing wrong with choosing them—just understand the maintenance before buying.

For many busy households, simpler surfaces and accessible spaces make everyday cleaning easier.

15. Prefabricated vs. Custom Vanity

Custom vanities offer significant flexibility.

You can control:

• Exact dimensions
• Drawer configuration
• Cabinet colour
• Hardware
• Sink placement
• Materials

But custom cabinetry usually involves more planning and a higher budget.

A ready-made bathroom vanity can simplify the process considerably because the cabinet dimensions and configurations have already been established, and some models are available with coordinated countertops and sinks.

For many standard bathroom renovations, a well-selected prefabricated vanity can provide an excellent balance between design, functionality, cost and installation convenience.

Custom becomes particularly valuable when the bathroom has unusual dimensions or very specific requirements.

The Mistakes We Recommend Avoiding

After looking at all these considerations, most vanity problems come back to a few basic mistakes:

Measuring only the width.
Depth and clearance matter too.

Buying before checking plumbing.
Beautiful drawers don't help if the drain needs to run through them.

Automatically choosing the largest vanity possible.
Comfortable movement matters.

Assuming two sinks are always better.
Countertop and storage space have value too.

Choosing storage based on appearance.
Think about what you actually own.

Buying the faucet separately.
Sink and faucet geometry need to work together.

Ignoring cleaning and maintenance.
You'll live with the vanity much longer than you'll spend shopping for it.

Frequently Asked Questions

What should I consider first when choosing a bathroom vanity?

Start with your available space. Measure width, depth and height, then check doors, toilets, showers, plumbing and other fixtures before considering style.

What is the most practical bathroom vanity size?

There isn't one ideal size for every bathroom. A 24- or 30-inch vanity may suit a compact bathroom, while 36- and 48-inch vanities provide additional storage for medium spaces. Larger bathrooms may accommodate 60- or 72-inch vanities.

Should a bathroom vanity go all the way to the wall?

It depends on the vanity design and bathroom layout. The important thing is to avoid creating an awkward narrow gap that's difficult to clean while maintaining any necessary clearance.

Is a floating vanity better for a small bathroom?

It can be an excellent option. Seeing more of the floor can make a compact bathroom feel visually more open. However, wall construction and installation requirements should also be considered.

Is one sink or two better?

If two people frequently use the bathroom simultaneously, two sinks can be convenient. If not, one sink may provide more useful countertop and storage space.

What type of vanity provides the most storage?

Vanities with a combination of drawers and cabinets are often highly practical, but usable storage depends on sink size, plumbing and internal cabinet design—not simply the vanity's overall dimensions.

Should I choose the vanity or faucet first?

Choose the vanity and sink configuration first, then select a compatible faucet. Faucet-hole configuration, basin position, faucet height and spout reach all need to work together.

Is a bathroom vanity with a top easier to buy?

It can simplify the process because the cabinet and countertop are already designed to work together. Some packages also include a sink. Always check the individual product specifications to confirm exactly what's included.

Final Thoughts: Choose for the Way You Actually Live

If there's one principle we would emphasize after helping customers compare bathroom vanities, it's this:

Don't design your bathroom around the product photo. Design it around how you actually use the bathroom.

Measure first.

Think about your morning routine.

Decide what you need to store.

Check the plumbing.

Choose the sink configuration.

Then start thinking about colour, hardware and style.

A beautiful vanity matters—but a vanity that fits properly, stores what you need and makes your bathroom easier to use every day is ultimately the better choice.
