Choosing a bathroom vanity isn’t just about picking a style — size matters. A vanity that’s too big can overwhelm the room, while one that’s too small may lack storage and function. This quick guide will help you determine the perfect size vanity for your space, whether you’re outfitting a powder room or a large master bath.
1. Measure Your Space Accurately
Start by measuring the width of the wall where your vanity will sit. Also account for:
- Plumbing placement
- Door swing and entry clearance
- Distance from toilet or bathtub (at least 18″ is ideal)
- Mirror or medicine cabinet alignment
Tip: Always leave at least 1″–2″ of space on each side between your vanity and the walls for easier cleaning and airflow.
2. Consider These Common Vanity Widths
- 24″–30″: Great for small bathrooms or powder rooms
- 36″–48″: Standard size for most full bathrooms
- 60″–72″: Ideal for master baths with double sinks

3. Don’t Forget the Depth and Height
Most vanities are 20″–21″ deep. In tight spaces, consider shallow depth options at 18″ or even 16″. As for height:
- Standard: 32″–34″ tall
- Comfort Height: 36″+ for better ergonomics
4. Factor in Your Sink Type
If you’re using a vessel sink, you may want a lower vanity. For integrated sinks, standard height works well. Make sure your faucet and mirror placement align properly with your sink type.
