If you’re renovating a small bathroom, choosing the right vanity size is one of the most consequential decisions you’ll make. A vanity that’s too large will make the room feel cramped. One that’s too small may not give you the storage and counter space you need.
In this guide, we’ll walk you through every standard vanity size, explain which options work best for small bathrooms, and share practical tips for measuring and selecting the perfect vanity for your space.
Standard Bathroom Vanity Sizes
24-Inch Vanity
The 24-inch vanity is the smallest standard option, designed for tight spaces.
- Best for: Powder rooms, half baths, very small ensuites, and basement bathrooms.
- Sink type: Single basin, undermount or integrated.
- Counter space: Minimal.
30-Inch Vanity
The sweet spot for small bathrooms. Provides noticeably more counter space and storage than a 24-inch model.
- Best for: Small full bathrooms, guest bathrooms, and upgraded powder rooms.
- Sink type: Single basin with room for a centred or offset sink.
36-Inch Vanity
Comfortable territory for a single-sink vanity with good balance of counter space and storage.
- Best for: Medium-sized main bathrooms, larger guest bathrooms.
48-Inch Vanity
Popular choice for primary bathrooms. Can accommodate single large sink or double sink.
60-Inch Vanity
Standard for comfortable double-sink setup. Each person gets their own basin.
72-Inch Vanity
Largest standard size, generous double-sink layout with substantial counter space.
Which Vanity Sizes Work Best for Small Bathrooms?
For small bathrooms common in older Kitchener homes, Waterloo condos, and basement bathrooms, your best options are the 24-inch, 30-inch, and 36-inch sizes.
Choose 24-inch if under 35 sq ft or for half baths. Choose 30-inch if measurements allow — the optimal choice for small full bathrooms. Choose 36-inch if your wall can accommodate it without encroaching on traffic flow.
Wall-Mounted vs. Freestanding Vanities
Wall-Mounted (Floating)
- Create an illusion of space by exposing the floor
- Easier to clean underneath
- Modern aesthetic with adjustable height
Freestanding
- More storage potential down to the floor
- Easier installation
- Traditional or transitional look
Our recommendation: For making the room feel spacious, choose wall-mounted. For maximizing storage, choose freestanding.
How to Measure for a Bathroom Vanity
- Wall width. Measure corner to corner or to any obstruction.
- Available depth. Standard 18-22 inches; shallow-depth (16-18″) frees floor space.
- Toilet clearance. Minimum 15 inches from toilet centre to adjacent fixture.
- Door swing clearance. Open the door fully and check for interference.
- Plumbing location. Note drain and supply line positions.
- Height. Standard 30-32″; comfort-height 34-36″.
Small Bathroom Vanity Tips
- Prioritize drawers over doors for better organization
- Consider a vessel sink if counter space is limited
- Light colours and simple lines keep the vanity from dominating
- Add a mirror with integrated storage
- Check countertop overhang against adjacent fixtures
