How to Choose the Right Bathroom Vanity Size
One of the most important steps in any bathroom remodel is choosing the correct vanity size. Too small, and you’ll sacrifice function. Too large, and your space may feel cramped. In this guide, we’ll walk you through how to choose the right bathroom vanity size based on space, layout, and needs.
1. Measure Your Available Wall Space
Start by measuring the wall where the vanity will go — width, depth, and height. Leave room for side clearance, drawers, and swinging doors. Standard single vanities range from 24″ to 48″, while double vanities typically start at 60″.
2. Consider Your Bathroom Layout
Is your bathroom long and narrow? Or wide with multiple fixtures? Make sure your vanity won’t block walkways, doors, or toilets. Corner vanities or floating models are great for tricky layouts.
3. Match Vanity Size to Function
Think about how the space will be used. A guest bathroom may only need a compact vanity like the Chianti 24″ Vanity in Whitewashed Walnut. For daily use or shared spaces, go bigger for more countertop and storage.
4. Balance Proportion with Style
Choose a vanity that complements the scale of the room. In small bathrooms, a 30″ vanity like the Dean 30″ in Mid-Century Walnut offers clean lines and ample storage without overwhelming the space.
5. Double Vanities for Shared Bathrooms
Primary bathrooms or family spaces often benefit from a double vanity. The Brittany 60″ Double Vanity in Sage Green offers a balanced mix of drawer and cabinet space.
6. Leave Space for Mirrors and Lighting
Make sure your mirror and lighting choices align with the width of your vanity. Double mirrors over a double vanity help maintain balance, while a centered mirror looks great over single vanities.
