Bathroom Vanity Cabinets: Sizes, Styles, and How to Choose

The vanity is the heart of any bathroom — it sets the style, provides essential storage, and supports the sink and countertop. Whether you are updating a compact powder room in a San Francisco flat or planning a spacious primary bath in the suburbs, choosing the right new vanity cabinet makes all the difference. Here is everything you need to know.

Standard Bathroom Vanity Sizes

Vanities come in a range of standard widths, and choosing the right one starts with your available space. Common widths include:

• 24–30 inches — ideal for powder rooms and small bathrooms.
• 36–48 inches — the most common single-sink range for full bathrooms.
• 60–72 inches — typically a double-sink vanity for primary bathrooms.

Beyond width, pay attention to:

• Depth. Standard vanities are around 21 inches deep; shallower depths (around 18 inches) help in tight spaces and narrow hall-style baths.
• Height. Traditional vanities sit near 32 inches, while "comfort height" vanities (around 36 inches, like kitchen counters) reduce stooping and are increasingly popular.

Single vs. Double Vanity

Single vanity

A single-sink vanity is the right call for most bathrooms under about 60 inches of wall space. It leaves more room for countertop and storage and keeps the layout simple. In smaller Bay Area bathrooms, a single vanity with smart internal storage often beats squeezing in two cramped sinks.

Double vanity

If you have 60 inches or more and share the bathroom, a double vanity is a genuine quality-of-life upgrade — two people can get ready at once without bumping elbows. Double vanities also signal a premium primary bath to future buyers, a plus for resale in competitive Bay Area markets.

Vanity Mounting Styles

Freestanding vanities

The classic, furniture-like vanity that sits on the floor. It offers the most storage, hides plumbing, and suits nearly every style from traditional to transitional.

Floating (wall-mounted) vanities

Mounted to the wall with open space beneath, floating vanities are a hallmark of modern bathrooms. They make the floor feel larger (great for small baths), simplify cleaning underneath, and deliver that clean, contemporary look so popular in Bay Area remodels. Just plan plumbing placement carefully, since it may be partly visible.

Door and Drawer Configurations

How a vanity is organized inside matters as much as its size:

• Door-only vanities maximize open interior space — good for storing larger items and accommodating plumbing.
• Drawer-heavy vanities keep daily essentials organized and visible, though drawers must be notched around the P-trap.
• Combination layouts — drawers on one side, a door cabinet on the other — offer the best of both and are our most-recommended setup.

Matching Style to Your Bathroom

Vanity door styles mirror kitchen cabinets, so the same principles apply:

• Shaker vanities are timeless and versatile — see our guide on Shaker vs. flat-panel styles.
• Flat-panel (slab) vanities create a sleek, modern, spa-like feel.
• Warm wood finishes bring spa-organic warmth, on trend for 2026.

For a cohesive home, many Bay Area homeowners coordinate their bathroom vanity finish with their kitchen cabinets — easy to do when both come from the same new-cabinet collections.

Storage and Finish Considerations

Bathrooms are humid, so finish durability is key. Factory-applied painted and engineered finishes resist moisture well; our guide on choosing finishes that last applies directly to baths. Inside, consider drawer organizers, a pull-out for the trash bin, and an outlet drawer for charging and grooming tools.

How to Choose the Right Vanity

• Measure your space first — width, depth, and the swing of the bathroom door.
• Count your users — single for most baths, double if you share and have the width.
• Match your home's style — and ideally coordinate with the kitchen.
• Prioritize the storage layout that fits your routine.
• Choose a moisture-friendly finish built for bathroom conditions.
