When it comes to bathroom design, few things have as much daily impact as your vanity.
It's where you start and end your day, so getting the height just right isn’t just a matter of aesthetics—it’s about comfort, functionality, and even compliance with building codes.
At Knotty Nuff Wood, we craft custom vanities that fit real-life people and their real-life needs—not just cookie-cutter dimensions.
But before you decide to go custom or stick with standard, let’s break down everything you need to know about standard bathroom vanity height—from traditional norms to modern trends, and even ADA requirements.
What Is the Standard Bathroom Vanity Height?
While the traditional bathroom vanity height was once around 30 to 32 inches, especially in homes built before the early 2000s, that's no longer the norm.
Those lower vanities were originally designed with accessibility in mind, particularly for children or shorter adults.
These days, though, 36 inches has become the new standard in most homes. In fact, at Knotty Nuff Wood, about 95% of the vanities we build are 36 inches high, especially for master bathrooms and modern remodels.
Often referred to as "comfort height," these taller vanities align more naturally with the average adult’s height, reduce strain from bending over, and even match most kitchen counter heights—creating a consistent flow throughout your home.
If you’re designing a new space or updating an older bathroom, 36 inches is very likely the height you’ll end up loving most.

Why Did the Standard Height Used to Be So Low?
Historically, the lower height made sense when bathrooms were shared spaces among adults and children.
It was also more affordable to mass-produce shorter cabinets and countertops. But as our lifestyles evolved—and as the average height of adults increased—so did our expectations for comfort.
That’s one reason why we at Knotty Nuff Wood often get requests for custom vanity heights.
People want something that feels tailored to them, not something designed in the 1970s for a one-size-fits-all approach.
Comfort Height vs. Standard Height: Which One’s Right for You?
Choosing between comfort height and standard height vanities isn’t just about following trends—it’s about tailoring your space to how you actually live.
Comfort Height (34–36 inches)
Comfort height vanities—also called “counter height”—sit at the same height as most kitchen counters.
They’ve become the new standard for master bathrooms, and here’s why:
Pros:
Better ergonomics for adults – Less bending means less strain on your back and neck.
Ideal for taller users – If you’re 5’9” or taller, this is usually the sweet spot.
Modern aesthetic – A higher vanity gives a sleeker, more contemporary vibe.
Consistent design – If your kitchen counters are at 36", matching heights across rooms can feel more intentional.
Cons:
Less kid-friendly – Younger children may struggle to reach the sink without a stool.
Not ideal for ADA compliance – Comfort height vanities can exceed ADA maximums, which matters for accessible homes or commercial builds.
Standard Height (30–32 inches)
The traditional vanity height still has a place, especially in secondary bathrooms or kid-focused spaces.
Pros:
Perfect for children – No stool necessary in most cases.
Budget-friendly – Standard-sized cabinetry tends to be cheaper and more readily available.
Code-aligned for ADA designs – More adaptable for universal design principles.
Cons:
Not great for taller adults – Regular use might lead to discomfort over time.
Feels outdated in some modern interiors – Can make a space feel slightly “off” if the rest of the home uses more contemporary proportions.
ADA-Compliant Vanity Height
If you're designing a bathroom that needs to meet ADA (Americans with Disabilities Act) standards—whether it's in a public/commercial space or simply to future-proof your home—vanity height becomes a code issue, not just a style choice.
ADA Bathroom Vanity Height Requirements:
Maximum height: 34 inches from floor to top of counter
Minimum knee clearance: 27 inches high, 30 inches wide, and 19 inches deep (for wheelchair users)
Sink depth: Must allow for clear floor space beneath for seated access
Exposed plumbing: Must be insulated or otherwise protected to prevent leg burns or injuries
Important Detail:
ADA height includes the countertop, so if you're adding a thick stone slab, the cabinet base might need to be as low as 32 inches to stay compliant.
If you’re working on a residential remodel and want something accessible without sacrificing style, consider a wall-mounted vanity from Knotty Nuff Wood.
These allow precise height customization and can be installed with clear space underneath for seated users or those using walkers.
Countertops, Flooring & Installation
Getting the vanity cabinet height right is only step one.
The final height you experience—the one your toothbrush rests on every day—depends on a handful of additional variables. Here’s what to keep in mind during planning and installation:
Countertop Thickness: Small Numbers, Big Difference
Standard bathroom countertops are typically between 1" and 1.5" thick, depending on the material.
Natural stones like granite or quartz usually come in at 1.25" (or 3 cm), while more budget-friendly options like laminate can be thinner.
What That Means:
If your cabinet is 34", and your countertop is 1.25", your final height is 35.25". That could be perfect—or too tall—depending on your sink style and user needs.
Knotty Nuff Tip: We’ve seen a lot of people forget to account for the countertop and end up an inch too high for ADA, or just outside their comfort zone.
Always factor it in before cutting or ordering materials.
Flooring Matters, Too
Are you installing tile, engineered wood, or floating floors? The type and thickness of your flooring will also affect vanity height. This is especially true if:
You’re replacing a vanity but not replacing the flooring underneath
You’re doing a full reno and flooring is going in after the vanity (pro tip: it shouldn’t!)
Golden Rule:
Install your flooring first, then mount your vanity on top.
This ensures consistent height and a clean look—and makes it easier to swap the vanity later without leaving a weird “footprint” in the floor.
Installation Tips from the Workshop
We’ve been in enough homes to see how minor mistakes during installation can throw everything off. A few quick hits:
Use a laser level – Floors and walls aren’t always perfectly flat. Shimming might be necessary, especially in older homes.
Secure the vanity to studs – Don’t rely on drywall anchors alone.
Measure sink cutouts carefully – Especially if using vessel sinks, make sure the faucet placement works ergonomically with the final height.
Check plumbing rough-ins early – You don’t want to discover after install that your trap hits a drawer.
When to Go Custom: Breaking the Rules with Purpose
Yes, there are standards. Yes, there are building codes. But there’s also you—and your height, your lifestyle, your space, and your design vision.
Sometimes the best bathroom isn’t built around what’s “typical,” but around what’s right for your home.
Here’s when it makes total sense to ditch the standard and go custom.
You’re Way Taller or Shorter Than Average
Standard and comfort height vanities are designed for the average adult height (roughly 5'4" to 5'9"). But if you're 6'4" or 5'0", neither may feel quite right.
We’ve built custom vanities at 38 inches high for tall homeowners—and others as low as 28 inches for kids, little people, or clients with specific physical needs.
How to Find Your Perfect Height:
Stand at your kitchen counter or bathroom sink.
Pretend to brush your teeth.
Notice whether you’re slouching or raising your arms awkwardly.
That neutral elbow-bend position? That’s your ideal counter height.
You Want a Floating Vanity
Floating vanities (wall-mounted, no toe kick) aren’t just stylish—they’re incredibly flexible when it comes to height.
You can mount them exactly where you want them, and the open space underneath gives a lighter, more open feel—especially in small bathrooms.
They're also ideal for:
Accessibility design
Modern, spa-like aesthetics
Cleaning convenience (no toe kick = no dust trap)
Designing for Kids
If you’re remodeling a kid-only bathroom (or planning to stay in your home for a long time), a lower vanity makes sense—especially if you don’t want to deal with stools and step-ups every day.
That said, many families opt for comfort height vanities anyway, and use pull-out step drawers (which Knotty Nuff Wood can build right in!) so the vanity grows with the child.
You Have Unusual Plumbing or Layouts
Let’s be real: not every home is builder-perfect. Sometimes pipes are weird. Sometimes you’re trying to squeeze a full vanity into a very cozy powder room.
In those cases, going custom is the smartest move.
Whether it’s building around plumbing, incorporating angled walls, or creating extra-deep drawers that go around a drain, we’ve done it all—and those custom details are what make a bathroom truly yours.
How to Choose the Right Vanity Height for You

Final Tips Before You Decide
Measure twice. Seriously. And don’t forget to factor in countertop thickness and flooring.
Think about who uses the bathroom most. One-size-fits-all might not be the best approach.

Don't be afraid to go custom. If standard heights don’t cut it, that’s where Knotty Nuff Wood comes in.
