Why 400mm, 500mm & 600mm Vanities Are Your Small Bathroom’s Secret Weapon
That tiny bathroom. You need a basin. You desperately need storage. But you also need to be able to, you know, actually turn around and open the door without hitting your knees. It’s a common story we hear at The Blue Space every single day. People feel stuck. They think they have to choose between storage and space, or between style and function.
But here’s the good news. You don’t. So, let's get into it. Let's talk about these small bathroom heroes and figure out if one is right for you.
What Are We Even Talking About?
Okay, simple breakdown.
When we say "400mm, 500mm, or 600mm vanity," we’re talking about the width of the unit. That's the measurement from left to right as you stand in front of it. This little group of small vanities represents the most compact end of the spectrum.
400mm Vanities
These are the specialists. They are compact, often designed for just a basin and some minimal storage (like a single cupboard) below. They are the absolute problem-solvers for the tightest of spots.
500mm Vanities
This size is a real sweet spot. You get a usable basin, and you start to see better storage options, like a proper cupboard or even a set of drawers. It’s a fantastic all-rounder for small ensuites.
600mm Vanities
This is probably the most popular of the small sizes. Why? Because at 600mm wide, you get a really decent basin and genuinely useful storage. Many models come with two or three deep drawers. It’s a proper piece of furniture that still respects your limited floor space.
These units are designed from the ground up to maximise every last millimetre. The basins are often shaped to give you bench space where there shouldn't be any. The drawers are built to fit around the plumbing pipework. They are smart. They are efficient. And they prove that you don't need a giant bathroom to have a beautiful, functional vanity.
Where We See These Vanities Work Best
This is the fun part.
We’ve helped thousands of Aussies plan their bathrooms, so we’ve seen exactly where these compact vanities shine. They're not just for one type of home. They're for anyone with a tricky space.
The Classic Powder Room
This is the number one spot. That little room off the hallway, the one guests use. It might be just 900mm wide. You can't have a big, bulky vanity blocking the way. A 400mm vanity or a 500mm vanity is the perfect fit. It does its job perfectly without taking over. We often recommend a wall-hung vanity here. Floating it off the floor makes the tiny room feel just a little bit bigger.
The Squeezy Ensuite
Ah, the ensuite. Your personal space. But so often, it's a narrow rectangle where the door opens, you have the vanity, then the toilet, then the shower. All in a line. The walkway is critical. A 600mm vanity is often the hero here. It gives you enough storage for your daily routine. Paired with a mirrored cabinet above, you’re sorted. We also see lots of customers choose ensuite vanities in the 500mm size, especially slimline models. Slimline means it has a shallower depth (front to back), which is a total game-changer for narrow rooms. You won't believe the difference an extra 10cm of walkway makes.
City Apartment Bathrooms
We see this all the time in new apartments. The bathroom is stylish, but it’s... compact. A 600mm vanity is often the standard. A simple white vanity is a classic choice here, as it bounces light around and makes the whole room feel cleaner.
The Secondary or Kids' Bathroom
Got a small main bathroom that the kids use? You don't need a giant double vanity. A sturdy 600mm vanity with deep drawers is ideal. The drawers are easy for little ones to open, and you can keep bath toys, towels, and first-aid supplies tucked away. A freestanding vanity can be a great choice here. It sits firmly on the floor and often gives you maximum internal storage space.
The Smart Laundry Nook Think outside the bathroom. We've had customers use a 400mm vanity in a small European-style laundry. It acts as a small, stylish trough for soaking, with a cupboard below for detergents. It’s so much nicer than a basic plastic tub. Clever.
The Different Types: Let's Break It Down
Okay, so you're thinking a small vanity might be for you.
What kind should you get? This is where our range gets really exciting. Even in these compact 400mm, 500mm, and 600mm sizes, you have so many styles to choose from. You are not sacrificing design for size.
Mounting Style: Floor or Wall?
Wall Hung Vanities
These are a team favourite for small spaces. A wall-hung vanity, or 'floating' vanity, attaches directly to the wall. It doesn't have legs or a kickboard. The big win? You see the floor underneath. This visual trick instantly makes the room feel larger and more open. It’s also a dream to clean. You can mop right under it. No dust bunnies. The only catch is that your plumbing (especially the waste pipe) usually needs to be in the wall. So, it's a small chat to have with your plumber, especially in a renovation.
Freestanding Vanities
A freestanding vanity sits right on the floor. This is a more traditional look, but it has some massive practical benefits. First, it can often hide a multitude of sins. If your plumbing comes up from the floor (an 'S-trap'), a freestanding unit will hide it completely. No problem. They also tend to have a slightly larger internal storage cavity, as the whole box is usable space. They feel solid. Grounded. And they come in every style imaginable.
Shape and Style: This is Where You Add Personality
Slimline Vanities
This is the secret weapon. Width (400/500/600mm) is one thing. But depth (front-to-back) is the other critical measurement. A slimline vanity might be only 380mm, 300mm, or even 250mm deep. In a tiny powder room or a narrow ensuite, this is everything. It’s the difference between 'squeezing past' and 'walking past'. You can still get a perfectly usable basin, it’s just designed to be shallower.
Curved Vanities
We love, love, love curved vanities for tight spaces. Why? No sharp corners. When you’re in a small room, bumping your hip on a sharp vanity corner is a daily frustration. A curved or 'pill' shape softens the whole room. It guides the 'flow' of traffic around it. It just feels gentler. And it looks incredibly high-end. It’s a design choice that is also intensely practical.
Fluted Vanities
Who said a small bathroom has to be boring? It's the perfect place to make a statement. A fluted vanity (with that beautiful reeded or 'kit-kat' style timber front) adds texture and luxury. In a small 500mm or 600mm size, it becomes a stunning piece of furniture. It’s the hero of the room. We see customers do this all the time: simple tiles everywhere else, and one amazing fluted vanity. It just works.
Hamptons Vanities
Yes, you can get that classic, coastal, elegant look in a compact size. A Hamptons vanity is all about the details: the shaker-profile doors, the classic white finish, the beautiful handles. A 600mm Hamptons-style unit in a small bathroom or ensuite feels so fresh and light. It’s a timeless look that never fails.
Custom Vanities
What if you have a really weird space? A nook that’s only 580mm wide? Don't just settle. This is where custom vanities come in. We work with amazing Australian makers who can build a vanity to your exact width. You get to choose the colour, the top, the handle, everything. It’s the ultimate problem-solver and ensures not a single millimetre of precious space is wasted.
The Real Benefits of Going Small (And Smart)
So, why do we recommend these units so often?
It’s not just about "fitting something in." It's about what a smart compact vanity gives you.
1. It Creates Flow and Floor Space
This is the big one. The way we see it, a bathroom's first job is to be easy to move around in. A 400mm or 500mm vanity gives you back your floor. It makes the room feel less like an obstacle course. This improved 'flow' has a huge psychological impact. It just makes the room calmer and more pleasant to be in.
2. It Delivers Genius-Level Storage
It sounds like a contradiction, right? A smaller vanity with better storage? But it's true. An old 900mm vanity with one big cupboard is a black hole. You can't find anything. Bottles fall over. It's a mess. A modern 600mm vanity with two deep, soft-close drawers is a storage powerhouse. You pull the drawer out, and you can see everything from above. No more kneeling. It’s organised. It's accessible. It’s just smarter.
3. It Becomes a Stunning Feature
A small vanity is a low-risk, high-reward way to add personality. Because it’s a small piece, you can be brave. Go for that amazing fluted vanity from Otti. Choose a bold colour. Pick amazing handles. It won't overwhelm the room. It becomes the "jewel" of the space. We've seen so many customers fall in love with their bathroom because of one small, beautiful vanity.
4. It Can Save You Money
This is a practical one. Smaller vanities are generally more affordable than their giant 1200mm or 1500mm counterparts. But it’s not just the purchase price. A compact vanity might mean you don't need to move a doorway or a toilet to make the room work. It can simplify your whole renovation layout, saving you big money on plumbing and building work.
The Practical Stuff: What Our Team Always Recommends
You're almost there.
Before you add to cart, here are the practical things our expert team always tells customers to double-check. Getting this right is the key to a stress-free installation.
1. Plumbing, Plumbing, Plumbing
This is the most important chat to have with your plumber. Where is your waste pipe? Does it come out of the wall (a 'P-trap') or up from the floor ('S-trap')? A wall-hung vanity needs the pipe in the wall. A freestanding vanity can usually hide either. Get this confirmed before you buy.
2. Check the Taphole
This catches so many people out. Look at the vanity top. Does it have one taphole? Three tapholes? Or no tapholes? This dictates what kind of tap (a 'mixer' or 'three-piece tapware') you need to buy. If it has no tapholes, it's designed for wall-mounted taps. Which, again, is a chat with your plumber as the pipes need to be in the wall.
3. Drawers or Cupboards?
Our team is firmly on Team Drawer. For a 600mm vanity, two deep drawers will almost always be more practical than two cupboards. You can access the full depth of the unit. For very small 400mm vanities, a cupboard is more common, and it’s perfect for storing tall cleaning bottles or toilet paper.
4. Our Go-To Brands
We are very picky about the bathroom vanities we stock. We only sell brands we trust and would put in our own homes.
