Getting bored of your bathroom design? If you’re squeezed into a cramped, dated bathroom in one of Melbourne’s older homes, you already know the feeling: chipped tiles, awkward layouts, and a shower that seems designed for someone half your size.
The good news is, you don’t need a knock-down rebuild to fix it. With the right bathroom renovation services, smart layout tweaks, and realistic budgeting, even the tightest bathroom can feel bigger, brighter, and finally yours.
Let’s discuss small bathroom renovation ideas
Why Small Bathrooms Need a Different Approach
Small bathrooms leave no room for guesswork. In a larger space, an awkward decision might just look odd; in a small one, it can cost you a functioning door swing, a usable shower, or precious storage.
Every fixture, tile line, and cabinet has to earn its place, which is exactly why Melbourne’s older housing stock makes this trickier than it looks.
Following a general bathroom renovation guide is a good starting point, but small spaces need their own set of rules on top of that.
Typical Small Bathroom Layouts in Melbourne Homes

- Victorian and Edwardian terraces often have long, narrow bathrooms, sometimes with the toilet tucked into a separate room entirely. Great for period charm, less great for modern layouts.
- 1960s–70s brick veneer homes tend to have boxy bathrooms, typically around 1.5m x 2.5m—compact, square, and often locked in by structural walls.
- Apartments and unit ensuites are usually the tightest of all, hemmed in by shared walls and building plumbing stacks, which severely limits how much you can shift fixtures around without major cost.
Each layout comes with its own constraints—and its own opportunities. Getting the approach right from the start means fewer compromises (and fewer surprises) once renovations begin.
Layout Ideas to Make the Most of the Space
Before you get to tile samples and tapware finishes, the layout decisions you make will have the biggest impact on how spacious your bathroom actually feels.
Swap the Bath for a Walk-In Shower

Ripping out a rarely-used bathtub can reclaim roughly 1.5m x 0.75m of floor space, which is a huge win in a small room.
Pair it with a frameless glass screen (or no screen at all) to keep sightlines open and the space feeling bigger than it is.
Before you commit, though, it’s worth an honest conversation with the household: if the bath gets regular use (kids, unwinding after a long day) removing it might solve a space problem while creating a lifestyle one.
Consider a Wet Room Layout
A wet room does away with the shower screen or step entirely, creating one seamless, open floor.
It’s a striking option for small bathrooms, but it’s not a cosmetic change, it requires waterproofing to AS 3740 standards and precise floor falls directing water to the drain.
This makes the most sense when you’re already redoing the waterproofing membrane, rather than as a standalone upgrade.
Keep Fixtures in Their Existing Positions

It’s tempting to reposition the toilet, shower, or vanity for a better flow—but every move means relocating waste and supply lines, which adds real cost and complexity.
Knowing where your isolation valves sit is a good starting point, and from there, a plumber should check the existing waste stack position and floor gradient to confirm the change is actually realistic, not just desirable on paper.
Design Ideas to Make a Small Bathroom Feel Bigger
Once the layout is sorted, it’s time to think about how the room actually looks and feels day to day. This is where the right choices can make a cramped bathroom feel surprisingly open.
Large-Format Tiles in Light Tones

Tile size and colour do more heavy lifting than most people expect. Bigger tiles mean fewer grout lines, and fewer grout lines mean less visual clutter for the eye to process as it scans the room.
Grout lines, especially darker ones, break a space up into smaller segments, which subconsciously makes it read as busier and smaller than it is.
Stick with light, neutral colours like soft white, warm grey or a pale sandy tone, since these bounce natural and artificial light around the room instead of absorbing it the way darker tiles do. If you’re set on a feature colour, consider saving it for a single accent wall or niche rather than the whole room.
For an extra sense of space, try running the same tile from the floor straight up the wall, sometimes called a “waterfall” or continuous tile treatment.
It removes the visual break point where floor meets wall, tricking the eye into reading the room as one continuous surface rather than two separate planes stopped short by a skirting line.
Lighting and Mirrors

A single overhead light rarely does a small bathroom any favours, since it tends to cast flat, even light that makes the room feel a bit clinical and one-dimensional.
Layering task lighting, such as sconces either side of the mirror, with softer ambient lighting from a ceiling fixture or downlights, adds depth and warmth that a single bulb simply can’t achieve.
An oversized mirror is another easy win. Beyond the practical benefit, a large mirror adds a genuine sense of depth, visually doubling the room, and reflects extra light back into the space rather than letting it get absorbed by walls and tile.
Just keep in mind that any fittings installed in wet zones need to be IP-rated under AS/NZS 3000, so this part of the job belongs to a licensed electrician working alongside your plumber, not a weekend DIY project.
Built-In Storage

Clutter is the enemy of a small bathroom feeling bigger, and built-in storage solves this without eating into usable space.
A recessed shower niche keeps bottles, soaps and razors off the floor and benchtop entirely, so nothing interrupts your eye line or your movement around the room.
Wall-hung vanities are another smart move, freeing up visible floor space beneath the basin and making cleaning underneath far easier, no more mopping around pedestal legs or cabinet bases.
This works especially well in older homes, where a simple pedestal sink was often the original setup, since swapping it for a floating vanity instantly modernises the room while reclaiming valuable floor area.
Choosing Fixtures and Fittings for a Small Bathroom
With the layout and design decided, the final piece of the puzzle is choosing the right plumbing fixtures for a space that works hard, without cutting corners on compliance. For a broader look at what to weigh up beyond just tapware, our guide on choosing the right plumbing fixtures is a useful place to start.
Tapware That Meets Australian Standards

Every tap installed in an Australian bathroom must carry WaterMark certification. This isn’t a style preference, it’s a legal requirement, so it’s worth confirming before you fall in love with a tap online.
Wall-mounted mixers are a particularly smart choice for small bathrooms, since they free up valuable bench and floor space around the basin.
If you’ve dealt with drips or reduced pressure before, it’s also worth reading up on what causes a leaking mixer tap so you know what to look out for down the track.
Water-Efficient Fixtures
Small bathrooms are a great opportunity to go water-efficient. Aim for WELS-rated toilets and showerheads, ideally sitting at 4 to 6 stars.
Beyond the water savings, lower usage also means lower hot water demand, which matters more than people expect in an ensuite where hot water capacity is often limited to begin with.
DIY vs. Calling a Licensed Plumber
Once you’ve got a vision for the bathroom, the next question is how much of it you can tackle yourself and where you genuinely need to bring in a professional.
What You Can Reasonably DIY
If you’re handy and want to save a bit of budget, there are plenty of cosmetic jobs that don’t require a licence:
- Painting walls, ceilings and cabinetry
- Swapping out tap handles or cabinet hardware
- Re-grouting tired-looking tile joints
- Styling touches like towel rails, shelving and accessories
These jobs won’t affect the bones of the bathroom, so there’s low risk if something doesn’t turn out perfectly. Worst case, you repaint or re-do it yourself.
What Needs a Licensed Plumber
Anything involving water, drainage or the structure of the room is a different story, and for good reason. In Victoria, plumbing work legally has to be carried out by a licensed plumber, and getting it wrong can mean leaks, mould, or costly damage down the track. This includes:
- Any work on taps, drainage or waste lines
- Anything that touches or breaks the waterproofing membrane
- Moving existing fixtures or adding new ones, since this often means relocating supply and waste pipes
It’s tempting to think a bathroom reno is mostly about tiles and paint, but the plumbing is what actually makes the room function day to day.
Getting this part right the first time, with someone qualified to do it, saves you from expensive rework later. Save your DIY energy for the finishing touches, and leave the pipework to the professionals.
FAQ About Small Bathroom Renovations in Melbourne
Here are some of the questions Melbourne homeowners search for most when they start planning a small bathroom renovation.
How much does a small bathroom renovation cost in Melbourne?
Costs vary widely depending on scope. A cosmetic refresh, think repainting, re-grouting and swapping tapware, sits at the lower end of the budget.
Costs climb significantly once you start moving fixtures, since relocating a toilet or shower means shifting waste and supply lines, which involves more labour and potentially reworking the waterproofing.
As covered earlier, the biggest single factor in your final price tag is whether your fixtures stay put or get repositioned.
How long does a small bathroom renovation take?
A cosmetic-only renovation, limited to surface-level updates, can often be completed in just a few weeks.
Once you introduce layout changes, such as moving plumbing or reconfiguring the waterproofing membrane, timelines stretch out considerably to account for trade sequencing, inspections and drying times between stages.
Do I need a permit to renovate a small bathroom in Melbourne?
A like-for-like renovation, where fixtures stay in their existing positions, typically doesn’t require a permit. However, structural changes, or altering a window, may trigger permit requirements.
Regardless of permit status, all plumbing and electrical work must be carried out by VBA-licensed trades, since this isn’t optional under Victorian regulations.
Can I move my toilet or shower to a different wall?
It’s often possible, but not guaranteed, and it usually adds cost. The feasibility depends on the position of the existing waste stack and the fall of your floor. This is exactly why a plumber should be consulted early, before your design is locked in, so you’re not left redesigning around a plumbing constraint halfway through.
Conclusion
At the end of the day, it’s the layout decisions, what stays, what moves and what gets removed entirely, that shape how a small bathroom actually feels, far more than any tile or tapware choice ever will.
Get that foundation right first, and the finishes simply do their job.
