How Wide Should Bathroom Vanities Be?

How wide should bathroom vanities be? In this article, our experts provide all the information you need when looking for the perfect bathroom vanity.

Are you doing a bathroom renovation and want to know what width your vanity should be? Here, we’ll discuss whether there’s a standard bathroom vanity measurement, what factors you need to consider when choosing a bathroom vanity, and how the experts at Builders Discount Warehouse can help you choose the right vanity.

How Wide is a Standard Vanity in Australia?

Generally speaking, the size of your vanity is entirely dependent on your wants and needs when designing your bathroom. However, the general rule of thumb is that a standard size, single sink bathroom vanity runs up to 1200mm wide; a double sink can be anywhere up to 1800mm in width.

Factors to Consider When Choosing Your Bathroom Vanity

Here are some factors to consider when considering the size of your bathroom vanity, and what width your vanity should be in order to fit in your bathroom without impacting on the rest of the space.

Size of Your Bathroom

The size of your bathroom vanity will largely depend on the size of your bathroom. For instance, you won’t want a 1800mm bathroom vanity if you’ve only got a really compact bathroom. It needs to fit with the space and not encroach too much on your shower/bath area, or any storage spaces you may have.

Where it’s Located

Planning the design of your bathroom is important, and will drastically impact the type of vanity you can have (and the width it can be). There’s no point designing your bathroom with the vanity opposite the toilet if your bathroom is on the opposite, smaller wall and will not fit in the space.

Height of Vanity

The other measurements (such as the height and depth) will influence the width of your bathroom vanity.

Sink Type

The type of sink you choose (i.e. undermount, in-built etc) will influence the width of your vanity and therefore the type of vanities you can choose from for your new bathroom.


While it may not seem like a big thing, the type of vanity you choose – and by extension – the width of the vanity you choose may be impacted by your aesthetic.

For example, if you’re going for a 70s or 60s style bathroom where pedestal sinks were the rage, choosing a luxurious double sink at 1600mm may be a little excessive and will not match your theme.
