Standard Bathroom Vanity Dimensions

Due to the wide variety of bathroom cabinet styles, there are no fixed standard dimensions for bathroom cabinets. However, as the market has evolved, a number of popular bathroom vanity sizes for vanities have gradually emerged. Some common vanity sizes include:

  • 60 cm (24 in) – compact powder rooms
  • 70–90 cm (28–36 in) – small to medium bathrooms
  • 120 cm (48 in) – medium single-sink vanities
  • 150–180 cm (60–72 in) – double-sink vanities

Of course, when considering the dimensions of bathroom vanities and sinks, it's essential to account for the needs of all users. For instance, if there are individuals with physical limitations in the household, you might prefer a shorter height to ensure everyone can comfortably reach the sink fixtures.

What Depth Should a Bathroom Vanity be?

When you're choosing your vanity, think about how this depth allows for comfortable use without overwhelming the bathroom. Too shallow, and you’ll run out of countertop area. Too deep, and the vanity might dominate the room.

The perfect depth for a bathroom vanity typically falls between 450mm and 500mm, striking a balance between functionality and space efficiency.

How High Should a Bathroom Vanity be?

Since there isn't a standard bathroom vanity size, make sure to measure both your space and the vanity.

Typically, a standard height of around 850mm suits most users. If you’re on the taller side, consider a comfort-height vanity between 900mm and 1000mm. This reduces bending and makes your tasks more seamless.

The Guide to Choosing the Right Bathroom Vanity Sizes

Choosing the right bathroom cabinet size starts with measuring your space accurately, so don’t skip this essential step. A well-planned cabinet not only enhances storage but also elevates the overall style of your bathroom. Here's a step by step guide to help you choose the right bathroom cabinet sizes.

Step 1: Measure the Width of Your Bathroom

Measuring the width of your bathroom is essential for selecting the perfect bathroom vanity size. Start by using a tape measure to determine the distance between walls, guaranteeing you account for any obstacles like doors or windows.

  • Smaller bathrooms consider vanities around 24 to 36 inches wide;
  • Medium spaces can accommodate 48 to 60 inches.;
  • Larger bathrooms allow for 60 to 84 inches, including double-sink options.

Step 2: Measure the Depth

Once you’ve determined the width of your bathroom, the next step is to assess its depth. Measuring the depth is essential for selecting a vanity that complements your space without overwhelming it.

Aim for a depth of 450mm to 500mm, making sure it fits comfortably in your layout.

  • Consider how the vanity’s depth affects movement around the room.
  • Shallower designs are ideal for tight spaces, while deeper units provide extra counter space.
  • Verify the depth allows for easy access to plumbing and storage.

Step 3: Measure the Height of Your Countertop

Standard heights typically range from 30 to 36 inches, but it’s important to take into account your specific needs. If you’re taller, a comfort-height vanity around 34 to 36 inches can alleviate strain while you use it daily. If multiple people share the space, aim for 32–36 inches (80–90 cm) as a universal height.

Step 4: Maintain a Functional Layout

Prioritize measurements and clearances to guarantee smooth movement and accessibility, while a well-placed vanity not only enhances aesthetics but also elevates usability.

  • 30 inches of open floor space in front.
  • 15 inches clearance from nearby fixtures like toilets or showers.
  • Choose a vanity size that complements the room dimensions, allowing for seamless integration with other elements.
