Most Australian homes, from inner-city apartments in Sydney and Melbourne to older weatherboard houses in Brisbane, have at least one bathroom that feels too tight. The good news is that you do not need to knock down walls to fix it. These bathroom ideas for small bathrooms focus on simple, proven changes: lighter colours, smarter storage, compact fittings and clear sight lines that make the same room feel larger.
Before you buy anything, measure your room properly. Note the width of the door swing, the distance from the toilet to the wall, and how much clear floor space you need to step out of the shower safely. In a small room, 5 cm here and 10 cm there can be the difference between a bathroom that works and one that frustrates you every morning. The ten ideas below are ordered from the biggest visual wins to the clever finishing touches, so you can start with one weekend job or plan a full refresh.

1. Float the Vanity
A floating vanity is fixed to the wall instead of sitting on the floor, so you can see the floor running underneath it. That small strip of visible floor tricks your eye into thinking the room is wider, and it also makes mopping much easier. Choose a unit about 60 to 75 cm wide for a tight bathroom, with one deep drawer for hair tools and one shallow drawer for daily items. A wall-hung design also lets you set the height to suit the people who use it most, which is a real help in a family home.
Keep the top clear. One soap dispenser, one toothbrush holder and a small tray are plenty. Everything else should live in the drawer, in labelled baskets if that helps you stay organised. If your budget allows, add a soft-close drawer and a basin with a small overflow shelf at the back. In Australia, a basic wall-hung vanity can start from around AUD 300, while a quality unit with stone-look top and soft-close drawers often sits between AUD 600 and AUD 1,200 before plumbing.
2. Choose a Glass Shower Enclosure
A shower curtain cuts a small bathroom in half every time you close it. Clear glass does the opposite: your eye travels straight through to the back wall, so the room reads as one open space. A fixed glass panel with a small opening is often the simplest choice, because it has no door swing to plan around. If you need a door, a sliding panel is better than a hinged door in a tight room, since it does not steal floor space when it opens.
Keep the glass clean with a quick squeegee after showers, and choose a simple frame in chrome or matte black to match your taps. Avoid heavy patterns on the glass if your room is very small, as frosted or busy glass can make the shower feel like a separate box. One fixed panel, good drainage and a single overhead shower head will usually give you the cleanest, calmest result.
3. Go Big With the Mirror
If you can only afford one upgrade, make it the mirror. A large mirror above the basin reflects light, doubles the view and makes the wall behind you feel further away. Run it almost as wide as the vanity, and take it up as high as practical without hitting a light fitting. A frameless mirror looks the most open, while a slim timber or black frame can tie the room together if you prefer a warmer look.
Lighting matters just as much as size. Put a light above the mirror, or a pair of small wall lights at face height on either side, so you can see clearly without harsh shadows. Warm white light, around 2700 to 3000K, feels welcoming and flatters skin tones. Our guide to vanity light height explains the placement rules that keep the light at eye level instead of glaring down from the ceiling.
4. Use Light Colours and Large Tiles
Dark, busy tiles chop a small room into pieces. Light colours do the reverse: white, soft grey, pale sage and warm beige bounce light around and blur the edges of the room. Large-format floor tiles, such as 60 x 60 cm, help even more because there are fewer grout lines to break up the floor. If you can run the same tile from the bathroom floor into the shower area, the whole floor will read as one continuous surface.
You do not need an all-white room. Keep the main walls and floor pale, then add one feature: a timber-look vanity top, a green tiled shower wall, or brushed brass taps. That one contrast stops the room from feeling flat, while the pale base keeps it open. In the photo above, the white walls and pale floor do the heavy lifting, while the towel rail and green shower tiles add warmth and personality without crowding the space.
5. Pick a Wall-Hung Toilet
A standard toilet with a visible cistern takes up more room than most people realise. A wall-hung toilet hides the cistern inside the wall, so only the bowl projects into the room, often saving 10 to 15 cm of depth. That extra space can be the difference between comfortable leg room and knees brushing the door. Cleaning is easier too, because there is no base sitting on the floor to collect dust.
Wall-hung toilets do cost more to install, since the frame must be fixed securely inside the wall, so get a licensed plumber to quote the full job, including any wall work. If a full wall-hung model is out of budget, a compact close-coupled toilet with a short projection is a good middle step. Pair it with a wall-hung vanity, as shown above, and the floor will stay visible across the whole room.
6. Use a Corner Basin
Corners are the most wasted space in a small bathroom. A corner basin fits neatly into that dead angle, leaving the main wall free for the toilet, shower or storage. This is a smart fix for a powder room or an ensuite where a full-width vanity would block the door or crowd the walkway. Look for a basin about 40 to 45 cm across, with a small wall-mounted tap so the basin itself can stay shallow.
Corner basins work best when the rest of the room stays simple. Keep the mirror above it modest, add one hook for a hand towel, and avoid a bulky cabinet underneath if you want the room to feel open. If you need storage, a slim mirrored cabinet on the next wall is better than a wide vanity that fights the corner shape. Measure twice before ordering, because corner models vary more than standard basins.
7. Try an Open Wet-Room Shower
A wet-room style shower has no tray edge and no door to swing, just a gently sloped floor that drains to one point. In a very small bathroom, removing the shower door alone can free up the space you need to move comfortably. The shower head goes on the far wall, the floor is fully tiled and waterproofed, and a single glass panel, if you want one, keeps most splashes in place.
Waterproofing is not a place to cut corners. The whole floor and the lower walls must be sealed by someone who understands Australian waterproofing standards, or you risk leaks into the room below. Plan storage inside the shower too: a recessed niche keeps shampoo and soap off the floor and out of the way. Our guide to shower niche height shows the comfortable reach heights to use, so bottles sit where you can grab them without stretching.
8. Add a Mirrored Cabinet
One of the most common reader questions is where to store toiletries when there is no room for a cabinet. A mirrored cabinet answers it: it looks like a mirror, but opens to reveal shelves for medicines, skincare and daily essentials. Because it sits inside or on the wall, it uses zero floor space. Choose a cabinet at least 50 cm wide if you can, with adjustable shelves so tall bottles fit on one side and small items on the other.
For renters, a surface-mounted mirrored cabinet is easier than a recessed one, and it can often be fitted with basic fixings. If you own the home and are renovating, a recessed cabinet set into the wall cavity looks neater and sticks out less. Either way, keep the front clear: a cabinet covered in magnets and notes stops working as a mirror. Put daily items inside, backups in a basket elsewhere, and wipe the mirror weekly so the room keeps its bright feel.
9. Plan a Compact All-in-One Layout
Sometimes the best idea is not a single product but a better layout. In the smallest rooms, put the basin on one wall, the toilet beside it, and the shower in the remaining corner, so each fitting uses the wall it fits best. Avoid placing the toilet directly opposite the door if you can, since that is the first thing you see. A small stool or folding step under the basin, as shown here, can hold a towel without needing a separate piece of furniture.
Before you move plumbing, draw the room to scale on graph paper or a free room-planner app. Mark the door swing, then check that you have at least 75 cm of clear space in front of the toilet and basin. Moving a waste pipe is expensive, so keep the toilet near its current position if possible and change the vanity and shower around it. A layout that looks tight on paper will feel tighter in real life, so leave a little breathing room wherever you can.
10. Keep the Basin Small in a Powder Room
A powder room only needs a basin for hand washing, so there is no reason to fit a full-size vanity. A compact basin, about 40 cm wide, with a slim tap and a small shelf for soap is enough, and it leaves room to move. Wall-mount the basin if you can, so the floor stays clear, and add a single hook for a hand towel instead of a wide towel rail that eats wall space.
This is also the room where small details matter most. A round mirror, a good light and one neat soap dispenser will make a tiny powder room feel finished, while a cluttered shelf will make it feel cramped. Keep spare toilet rolls in a basket on the floor or in a nearby cupboard, not stacked on the basin. When guests use the room, they will notice the clean surfaces far more than the size of the basin.
FAQs
How can I add storage to a small bathroom without drilling?
Use a freestanding over-toilet rack, a slim rolling cart, an over-door organiser or a tension-pole caddy in the shower. Adhesive hooks and rails work for light towels and robes, but check the weight rating first and avoid sticking them to fresh paint. Keep heavy items low and close to the wall, so nothing topples when the door closes.
What is the best vanity size for a small bathroom?
For most compact Australian bathrooms, a vanity 60 to 75 cm wide works well. Go narrower, around 45 to 55 cm, for a powder room or a room under 2 square metres. Measure the door swing and the clear space in front of the vanity before you order, and choose drawers over doors if you want easy access without kneeling.
Should I remove the bath to make a small bathroom feel bigger?
Removing a bath and fitting a walk-in shower usually makes a small room feel much larger, and it is a popular choice for ensuites. Keep at least one bath in the house if you have young children or plan to sell to families, since many buyers still want a bath. If you keep the bath, a clear glass screen instead of a curtain will help the room feel open.
How do I stop a small bathroom from feeling damp and mouldy?
Run the exhaust fan during every shower and for 15 to 20 minutes afterwards, and open a window when you can. Wipe down the shower glass, fix dripping taps quickly, and choose mould-resistant grout and paint for wet areas. Good ventilation matters more than any decor choice, because damp will damage paint, grout and cabinetry over time.
Can I renovate a small bathroom on a tight budget?
Yes. Start with paint, a large mirror, new taps and towel rails, and better lighting, which together can transform a room for a few hundred dollars. Save plumbing moves and waterproofing for a proper renovation budget, and get at least three quotes for that work. A cosmetic refresh first also helps you learn what really bothers you before you spend on a full rebuild.
Final Thoughts
A small bathroom does not need to feel like a compromise. Float the vanity, let the mirror and light do the work, keep colours pale and storage off the floor, and the same room will feel calmer, brighter and far easier to use. Start with the change that solves your biggest daily annoyance, whether that is a cluttered bench, a door that hits the toilet, or a dark shower corner, and build from there.
If you are planning a larger project later, our modern luxury bathroom ideas can help you compare finishes and layouts for a bigger room. For now, measure carefully, choose compact fittings that suit Australian homes, and keep surfaces clear. Small, well-chosen changes will give you a bathroom you enjoy using every single day.
