900mm Bathroom Vanities: Why This Is the Most Popular Size
If there’s one thing I’ve noticed over the years helping Perth homeowners plan their bathroom renovations, it’s that the 900mm bathroom vanity is the size most people end up choosing. It’s not too big, not too small, and it works in a wide range of bathrooms — from ensuites to compact family bathrooms.
A 900mm vanity offers a practical balance between space, storage, and cost. You get enough cupboard or drawer room for everyday bathroom items, but it won’t dominate the room or make the layout feel cramped. That’s why it’s such a popular bathroom vanity size for everyday renovators.
If you’re planning a bathroom renovation and wondering whether a 900mm bathroom vanity is the right choice, it’s worth understanding why this size works so well in so many homes.
What is a 900mm Bathroom Vanity?
A 900mm bathroom vanity refers to the width of the vanity cabinet. In simple terms, the unit measures 900 millimetres across from one side to the other. This size sits comfortably between smaller compact vanities and larger double-basin units, which is why it works so well in many bathrooms.
Most 900mm vanities also follow fairly standard proportions. The depth typically ranges between 450mm and 500mm, which provides enough bench space without pushing too far into the room. Height usually sits around 850mm to 900mm, depending on whether the vanity is freestanding or wall-hung.
A 900mm-wide bathroom vanity is almost always designed as a single-basin vanity unit, which suits the majority of Australian bathrooms. Many 900mm vanities are sold as a complete unit with a basin already included. These usually feature an integrated ceramic vanity top, although some designs allow you to install an above-counter basin on a separate vanity top.
Common basin options include:
- Integrated basins, where the basin is moulded into the vanity top
- Above-counter basins, which sit on top of the vanity top
- Inset basins, which are slightly inset into the vanity top
From a practical point of view, this size provides a comfortable amount of storage in the vanity cabinet while still leaving plenty of floor space around the toilet, shower, or bath. In my experience, it’s a size that fits nicely into most bathroom layouts without making the room feel cramped.
Why 900mm Vanities Are the Most Popular Choice
When customers choose a new vanity, a 900mm vanity often works best. It provides a good amount of storage and bench space, but it still fits comfortably in most bathrooms. It simply works well in most situations. It offers enough space to be practical, without taking over the entire bathroom. For everyday renovators, that balance is exactly what they’re looking for.
Ideal size for most bathrooms
A 900 vanity unit fits comfortably into many common bathroom layouts. It works particularly well in ensuites, apartment bathrooms, and smaller family bathrooms where space needs to be used carefully.
In fact, many people renovating older homes are replacing a smaller vanity with a 900mm unit because it provides more bench space and storage without making the room feel cramped. For many layouts, it ends up being the most practical bathroom vanity for a small bathroom while still feeling generous enough for daily use.
That’s why it’s often considered a standard bathroom vanity size for Australian homes.
Offers practical storage
Storage is another reason this size is so popular. A 900mm vanity cabinet provides enough room for everyday bathroom essentials while keeping the space organised.
Depending on the design, you’ll typically find a mix of cupboards or vanity drawers. Drawers are particularly useful because they allow you to see and access items easily, while cupboards provide space for taller items such as cleaning products or spare toiletries.
For many households, this extra space makes a noticeable difference. Instead of clutter building up around the basin, everything can be neatly stored away. It’s a simple but effective bathroom storage solution that helps keep the room tidy.
Affordable compared to larger vanities
Another advantage is price. A 900mm vanity sits comfortably in the middle of the market. It offers more functionality than smaller units but remains far more budget-friendly than larger options.
Once you move up to 1200mm or 1500mm vanities, costs tend to rise quickly due to the larger cabinet, wider vanity top, and often double basins.
For many Perth renovators working to a realistic budget, a 900 vanity delivers the right balance. It provides the storage and bench space people want while still being an affordable bathroom vanity choice.
Is a 900 Vanity Right for Your Bathroom?
A 900mm vanity suits a wide range of bathrooms, which is why it’s such a common choice during renovations. For many Perth homes, it provides enough bench space and storage without taking up too much of the room.
This size works particularly well in small to medium bathrooms where space needs to be used efficiently. It’s also a great fit for ensuites and investment properties, where a practical and reliable layout is often the priority.
That said, it’s still important to check that the vanity will work comfortably within your bathroom layout before making a decision. Start by measuring the available wall space to make sure the vanity dimensions fit properly. You’ll also want to consider the position of existing plumbing, along with the clearance around nearby fixtures such as the toilet or shower.
If the vanity is squeezed into the space, the bathroom can quickly feel cramped. Allowing enough room to move around the vanity makes a big difference to how the room functions day to day.

Storage Benefits of a 900mm Vanity
One of the main reasons people choose a 900mm vanity is the extra storage it provides. Compared with smaller units, the wider cabinet gives you much more space to keep everyday bathroom items organised and out of sight.
Most designs include a mix of cupboards or drawers, giving you flexible bathroom storage that works for different households.
Some of the main storage benefits include:
- More space for everyday items – A 900mm vanity comfortably stores toiletries, cleaning products, spare toilet paper, and other bathroom essentials.
- Better organisation with vanity drawers – Drawers make it easier to organise smaller items such as cosmetics, grooming products, and medicines because everything is visible and easy to reach.
- Room for taller items – Cupboards provide space for bulkier items like hair dryers, cleaning supplies, or extra bottles.
- A cleaner, less cluttered vanity top – With more vanity cabinet storage available, everyday items can be stored inside the cabinet instead of sitting around the basin.
For many households, this extra storage is what makes a 900mm vanity feel much more practical for daily use.
Popular Styles of 900mm Bathroom Vanities
Another reason 900mm bathroom vanities are so popular is the wide range of styles available. Whether you’re updating a modern bathroom or renovating an older home, you’ll find a design that suits your space and layout.
Two of the most common styles are freestanding and wall-hung vanities.
900mm Freestanding Vanities
A freestanding vanity is the traditional option and remains very popular in many Australian homes. The unit sits directly on the floor and typically includes a full vanity cabinet with cupboards or drawers.
Freestanding vanities are often chosen because they are straightforward to install and work well in many bathroom layouts. They also tend to offer generous internal storage, which makes them a practical choice for family bathrooms.
900mm Wall-hung Vanities
A wall-hung vanity (sometimes called a floating vanity) is mounted directly to the wall, leaving the floor space underneath visible. This style has become increasingly popular in modern bathroom designs.
Because the cabinet is raised off the floor, a wall-hung vanity can make the room feel more open and spacious. It also makes cleaning the bathroom floor easier, which many homeowners appreciate.
If you’re deciding between these two options, our comparison of Freestanding vs Wall Hung Vanities explains the differences in more detail and can help you choose the best option for your renovation.
Both styles are widely available as modern bathroom vanity designs, so the best choice usually comes down to your bathroom layout and personal preference.
How Much Do 900mm Bathroom Vanities Cost?
One of the reasons many renovators choose a 900mm vanity is that it offers a good balance between functionality and price. It provides more storage and bench space than smaller vanities while still remaining affordable for most bathroom renovations.
At Ross’s Discount Home Centre, our 900mm bathroom vanities typically range from $440 to $1,040, depending on the configuration and finish you choose.
The vanity cabinet price can vary based on a few key factors:
- Vanity top option – Many vanities are available with different top configurations, including cabinet-only units, integrated basin tops, or stone vanity tops without a basin
- Basin and tap hole configuration – The basin setup can also influence the price, particularly if the vanity top is available with different tap hole options or designed to suit an above-counter basin
- Cabinet construction – Materials such as PVC or moisture-resistant board can influence durability and cost.
- Hardware quality – Features such as soft-close vanity drawers and quality hinges may increase the price slightly but improve everyday usability.
Most homeowners tend to choose a mid-range option that balances quality and affordability. For example, the 90cm Jessica PVC Vanity Unit, priced around $640, is a popular choice because it offers good storage, durable construction, and a clean, modern look.
For many Perth renovators, a 900mm vanity sits right in the sweet spot. It provides practical storage and a comfortable vanity top without pushing the renovation budget too far.
Why 900mm Vanities Are Ideal for Bathroom Renovations
When planning a bathroom renovation, choosing the right vanity size can make a big difference in how the space functions day to day. In many cases, a 900mm vanity is the most practical option because it fits comfortably into a wide range of bathroom layouts.
Some of the key advantages include:
- Works in most bathroom layouts – A 900mm vanity suits many bathrooms, including ensuites and smaller family bathrooms, without dominating the room.
- Easy upgrade from smaller vanities – Many older homes still have 600mm or 750mm units. Upgrading to a 900mm vanity gives you more bench space and storage while still fitting comfortably along the same wall.
- Better balance of storage and floor space – You gain useful cabinet storage without sacrificing too much room in the bathroom.
- Practical choice for everyday renovations – For many Perth homeowners, it offers the right mix of functionality, style, and affordability.
