Right down to the last centimetre.
Find the perfect-sized vanity for your bathroom with our handy guide. We cover vanity dimensions, how to measure your space and tips on choosing your next bathroom vanity model.
Step 1: Determine Project Scope
If you’re replacing an existing vanity with the same size, simply measure the length, width and depth of your current vanity and choose a replacement with the same dimensions. If you’re starting from scratch, your bathroom’s available space will dictate your next steps.
Step 2: Measure the Width of Your Space
To find the width of your space, measure from wall to wall (side to side), taking into account where your bathroom and shower doors swing. Make sure these doors won’t hit your vanity. To accommodate a single-sink vanity, you’ll need at least 45cm of width available. For a double-sink vanity, you’ll need at least 120cm of width available.
Step 3: Measure the Depth of Your Space
To find the distance of usable space, measure from the back wall outward. Remember: you’ll need clearance for vanity drawers and doors to open, and enough room for traffic to pass by easily. We recommend at least 75cm of clear floor space in front of your vanity in order to feel comfortable walking through. The most common vanity depths are 43 – 60cm.
Step 4: Measure the Height of Your Space
To find the right height for your vanity, measure from the floor up, factoring in faucet height and existing features, like the placement of a potential backsplash and electrical outlets. For floating vanities, adjust the mounting so your countertop sits waist-high (or slightly lower for small children). The standard vanity height is 76 – 92cm. However, more recently comfort-vanity heights are 92cm tall.
Standard Vanity Dimensions
Standard vanity dimensions are typically between 45 – 182cm wide, depending on how many sinks you have. The standard depth of a vanity is typically around 50cm, but narrower options are available. The standard vanity height is 81cm but ranges from 76 – 92cm.
