How to Choose the Right Bathroom Vanity Dimensions (Complete Guide)
Getting the dimensions right is the single most important decision when ordering a custom bathroom vanity. Here's exactly how to measure your space and choose width, height and depth with confidence.

Start with the available width
Measure the wall where the vanity will sit, then subtract a few centimeters of clearance on each side if it fits between two walls. With a custom vanity you are not limited to standard sizes — you can order any width to the exact centimeter.
For widths above 120 cm, a vanity is typically built as two identical cabinets installed side by side. This keeps the piece structurally sound and easier to deliver, while looking like one seamless unit.
Choosing the height
Comfortable vanity height usually falls between 80 and 90 cm including the countertop. Taller users often prefer the upper end. If you are wall-mounting the vanity, you also control the installation height, so think about who will use it most.
Why 50 cm depth is standard
A depth of 50 cm comfortably fits most washbasins and gives generous drawer storage while leaving room to move in the bathroom. Going shallower (40–45 cm) is great for small or guest bathrooms; going deeper suits large basins or double setups.
A quick measuring checklist
Before you configure, have these numbers ready:
- Wall width and any obstacles (pipes, radiators, door swing)
- Height of existing plumbing connections from the floor
- Distance from the wall to the nearest fixture (toilet, shower)
- Whether you want wall-mounted or floor-standing
Frequently asked questions
What is the standard bathroom vanity depth?
The standard depth is 50 cm, which fits most basins and gives good drawer storage. Shallower 40–45 cm options suit small bathrooms.
What is the ideal bathroom vanity height?
Including the countertop, 80–90 cm is comfortable for most people. Wall-mounted vanities let you set the exact height.
Can I order a vanity wider than 120 cm?
Yes. Above 120 cm the vanity is built as two matching cabinets side by side so it stays sturdy and ships safely.
