Small bathroom ideas tend to get sold as décor: a paint colour, a round mirror, a plant on the shelf. They help, but they are finishing touches. The changes that actually make a compact room feel larger are about what sits on the floor, what breaks up the walls, and how the door and shower use the space.
This guide goes through those moves roughly in order of impact, with the trade-offs a renovator needs to know before committing to any of them.
Start with the floor you can see
The eye judges a room's size mostly by how much floor it can see. Anything that stands on the floor — a vanity kickboard, a toilet cistern, a shower base with a lip — cuts that visible area down.
Wall-hung vanity. Lifting the vanity 200–300mm off the floor shows the tile running underneath and back to the wall. Drawers are more useful than doors in a shallow unit. A slimline depth of around 400–460mm (rather than a standard 550mm or so) can make a real difference in a narrow room, provided the basin still suits. Vanity choice is its own subject; here the point is simply to get it off the floor.
Wall-hung toilet with an in-wall cistern. The cistern goes into a framed wall cavity, the pan is bracketed off the floor, and the room gains a little depth and a lot of cleanability. The flush plate doubles as an access point, but it needs to be planned at the framing stage — this is not a swap you make at fit-off. If the toilet sits on an external or brick wall, a thicker false wall may be needed, which gives some of that depth back.
No shower base. A moulded base sits proud of the floor and draws a hard line across it. Tiling the floor continuously into the shower, with falls built into the screed, removes that line. It is more demanding work for the waterproofer and tiler, so it needs to be specified and detailed properly, but in a small room it changes how everything reads.
Remove the frames and swings
One fixed glass panel. A framed corner enclosure with a pivot door is a box inside a box. Replacing it with a single fixed panel — no door, no top rail — lets the eye run to the back wall. It works when the shower has enough length for the water to stay inside the wet area; in a very tight room a short return panel or a slightly longer fixed panel may be needed.
Sliding or pocket doors. A standard hinged door sweeps a quarter-circle of floor that can never hold anything. A cavity sliding door gives that space back. The wall it slides into must be clear of pipes, switches and wiring, and the cavity frame is installed during framing. Where a cavity door is not possible, rehanging the door to open outward (where the corridor allows) can achieve some of the same effect.
Hinges on the right side. Even with a hinged door, check which way it opens. A door that swings into the toilet or vanity is a daily nuisance; flipping the hinge side costs little during a renovation.
Walls: fewer lines, more depth
Larger-format tiles. A 600×300 or 600×600 tile has far fewer grout lines than a small format, and a calm surface reads as larger. The trade-off is set-out: in a narrow room, a large tile can leave awkward thin cuts at the perimeter, so ask the tiler to show where the cuts will land before you commit to a size.
One tile, floor to wall. Using the same tile on the floor and walls — or at least the same colour — blurs the corners of the room. It is one of the most effective small-bathroom ideas and costs nothing extra in material.
Tile to the ceiling. A tile line at two metres with paint above draws a horizontal band around a small room. Tiling full height removes it and lifts the eye.
Recessed storage. A shower niche set into the wall cavity keeps bottles off the floor and off ledges. Likewise, a recessed or semi-recessed mirror cabinet gains storage without projecting into the room. Both depend on what is in the wall — studs, pipes and wiring — so they are set out at framing.
Light, mirror and colour
Light the face, not the back of the head. A single ceiling downlight behind you casts shadows exactly where you need to see. Lighting at or around the mirror — a backlit mirror, wall lights either side or a strip above — makes the room feel brighter and more usable. Wiring needs to go in at rough-in, and electrical work in wet areas must be done by a licensed electrician within the zones the wiring rules allow.
A mirror as wide as the vanity. A large mirror reflects the room back and makes it feel noticeably deeper. Running it the full width of the vanity is usually better than a small framed one.
Colour with restraint. Pale, warm neutrals help, but a small room in one light tone with one darker accent — a vanity front, tapware, a feature niche — tends to look more deliberate than an all-white box. Matt finishes hide water marks better than gloss.
Layout: corner or inline?
Small bathrooms usually fall into one of two plans.
Corner shower layout. The shower takes one corner, with vanity and toilet along the other walls. It suits squarer rooms. The risk is a cramped entry if the shower is too small; aim for a shower that is comfortable to turn around in rather than the minimum that fits.
Inline layout. Everything runs along one long wall — shower at the end, then toilet, then vanity — with circulation down the other side. It suits long, narrow rooms and ensuites, and it pairs well with a walk-in shower at the far end behind a single fixed panel, where the whole room reads as one run of floor.
Before changing the layout, find out where the existing wastes are. On a concrete slab, moving a toilet or shower waste means cutting the slab, which adds time and cost. Keeping the drainage where it is and changing everything above it is usually the better use of the budget. Upstairs rooms on timber floors are often more flexible.
Ventilation is not optional
A small room fills with steam fast and has less surface to spread it across. An extraction fan ducted to the outside — not into the roof space — sized for the room and on a run-on timer is what stops mould returning a year after the renovation. It is unglamorous and one of the best-value items on the list.
What not to do
- Do not choose a tile before the set-out. The layout decides the cuts, and the cuts decide how good the room looks.
- Do not squeeze the shower to fit a larger vanity. The shower is where comfort is felt most.
- Do not add a feature for its own sake. Every extra material in a small room is another line.
Getting it built
Most of these ideas are decided at framing and rough-in, not at fit-off, which is why they belong in the brief before anyone quotes. Our small bathroom renovations page sets out how a compact room is scoped, and the full bathroom renovation page covers the whole sequence from strip-out to fit-off. For a sense of the budget, see the bathroom renovation cost guide.
If you are in the Kellyville area, we can measure the room and give you a fixed quote on the ideas that suit it.

Questions people ask before they commit
What is the best way to make a small bathroom feel bigger?
Show more floor and remove visual breaks. A wall-hung vanity and toilet, a single fixed glass panel instead of a framed enclosure, and one floor tile running continuously into the shower do more than any colour choice.
Are large tiles a good idea in a small bathroom?
Usually. Fewer grout lines read as a calmer surface. The catch is the set-out: in a very narrow room a large format can leave thin slivers at the edges, so ask the tiler to plan where the cuts land before a tile is chosen.
Is a wall-hung toilet worth it in a small room?
In most cases yes. The cistern moves into the wall cavity, the pan clears the floor and the room gains a little depth plus a much easier floor to clean. It needs a suitable wall frame and an access panel, so it is decided at rough-in.
Should a small bathroom have a bath?
Only if someone in the house genuinely needs one. A bath takes a full wall. Where there is another bath in the house, swapping it for a generous walk-in shower is usually the single biggest gain in usable space.
Does a sliding door help?
A cavity sliding door removes the door swing, which in a small room can free up the space in front of the vanity or toilet. It needs a wall with no plumbing or wiring in the cavity, so check that before committing.
