How to Choose the Right Bathroom Vanity Size (and Why 36 Inches Is So Popular)

Choosing a bathroom vanity sounds simple until you start measuring. Too small and you lose precious storage and counter space; too large and the room feels cramped and hard to move through. This guide walks you through how to pick the right vanity size for your bathroom, and explains why the 36 inch vanity has become the most popular choice for homeowners.

Start with the space you have

Before you fall in love with a particular vanity, measure your bathroom carefully. Note the total wall width where the vanity will sit, then account for door swings, drawer clearance, and walking space. A good rule of thumb is to leave at least 30 inches of clear floor space in front of the vanity so it is comfortable to use.

Also check the location of your plumbing. If you want to keep installation simple and affordable, choosing a vanity that works with your existing rough-in saves both labour and money.

Common bathroom vanity sizes

• 24 inches and under. Ideal for powder rooms and small ensuites where floor space is at a premium. Storage is limited but the footprint is tidy.
• 30 to 36 inches. The sweet spot for most full bathrooms. You get a generous single sink, real counter space, and useful drawers and cabinets.
• 48 inches and up. Great for larger bathrooms and a good base for a double-sink layout if the width allows.

Why the 36 inch vanity is the most popular choice

There is a reason the 36 inch vanity is searched for and bought more than almost any other size. It hits a near-perfect balance for the average bathroom. At 36 inches you get enough countertop to set down everyday items, enough cabinet volume to hide cleaning supplies and toiletries, and a comfortable single-sink basin, all without overwhelming a standard bathroom.

The height matters too. Many modern 36 inch vanities are built at a comfort height that suits most adults, which reduces the stooping required by older, shorter cabinets. If you want to see how this plays out in a real product, take a look at our 36 inch vanity, which is designed around exactly this balance of storage and comfort.

Storage layout: drawers vs. doors

Size is only half the decision. How the interior is organized determines how useful the vanity actually is day to day. Deep drawers are excellent for hairdryers, brushes, and bulky items, while a cabinet with a shelf works well for taller bottles and cleaning supplies. A combination of both tends to serve most households best.

Because we build custom cabinetry, the interior of your vanity can be tailored to how you actually use the room rather than forcing your routine into a fixed layout. You can see the broader range of styles and finishes on our cabinetry page.

Match the vanity to your overall design

Finally, think about how the vanity fits the rest of your home. A vanity is essentially small-scale cabinetry, so the same principles that make a kitchen feel cohesive apply here: consistent door style, complementary hardware, and finishes that work with your flooring and wall colour. If you are renovating multiple rooms, coordinating the cabinetry across them creates a polished, intentional look.
