The best way to maximise space in a small bathroom is to sort the layout first, then choose space-saving fixtures such as a wall-hung toilet, a floating vanity, and a walk-in shower rather than a bath. Light colours, large-format tiles, and good lighting round things out by making the room feel bigger than it is.
If your home was built before the 1990s, chances are your bathroom is on the smaller side. Older Kiwi villas and bungalows were rarely designed with generous en suites, and even newer Auckland townhouses often squeeze the bathroom into a tight footprint to free up room elsewhere. It’s one of the most common frustrations we hear from homeowners across the region.
The good news is that a small bathroom doesn’t have to feel like a squeeze. With the right planning, a compact space can end up just as functional, and sometimes more stylish, than a larger one that was never thought through properly. Below, we’ve pulled together small bathroom renovation ideas that actually move the needle, along with a few mistakes worth avoiding.
Start With a Layout That Works
Before tiles, tapware, or colour schemes enter the conversation, sort the layout. It’s the single biggest factor in how spacious a small bathroom feels once everything is finished.
A few things worth keeping in mind:
- Keep plumbing in roughly the same spots where possible, since moving pipework eats into your budget for finishes.
- Avoid adding walls that aren’t needed. Every wall introduced chips away at usable floor space.
- Leave enough room to move comfortably between the vanity, toilet, and shower.
- Plan storage from day one instead of squeezing it in as an afterthought.
Choose a Walk-In Shower Over a Bulky Bath
Swapping a bathtub for a walk-in shower is one of the small bathroom renovation ideas we recommend most, and for good reason. A frameless glass shower opens up the sightline across the room, making the space feel airier, and it’s easier to keep clean, with fewer corners and no tub rim collecting grime.
That said, a bath is still worth keeping if you have young children or enjoy a long soak. In that case, a slimline or corner bath won’t dominate the room the way a standard tub does.
Install a Floating Vanity and Use Vertical Space
A wall-mounted vanity leaves the floor beneath it visible, which does wonders for the sense of space, is easier to mop under, and still leaves room for drawers or shelving below.
Beyond the vanity, the walls become your best friend. Tall cabinets, recessed shower niches, floating shelves, and a mirrored medicine cabinet add storage without taking up floor space. Even hooks behind the door free up a surprising amount of bench room.
Let More Light Into the Room
Nothing shrinks a bathroom faster than poor lighting. Larger mirrors bounce light around and visually double the space. LED strip lighting under vanities or around mirrors adds a soft glow without harsh shadows, and if you have a window, keep it unobstructed wherever privacy allows. Glass shower screens rather than solid walls also let light travel through the room instead of stopping dead at a barrier.
Choose Light Colours and Large Tiles
Whites, soft greys, and warm neutrals are the safe bet for a reason. Paired with large-format tiles and a consistent palette from floor to wall, they help a small room breathe, and fewer grout lines mean a cleaner, less busy look. Colour and tiling alone won’t fix a bad layout, though. They’re finishing touches, not a substitute for good planning.
Add Smart Built-In Storage and Space-Saving Fixtures
Shower niches, vanity drawers, mirrored cabinets, and hidden storage behind panels keep clutter out of sight. Wall-hung toilets, slimline vanities, corner basins, compact towel rails, and sliding doors instead of hinged ones each hand a little room back.
Keep the Design Simple
It’s tempting to add a feature wall or a few decorative touches, but in a small bathroom, restraint usually wins. Stick to one or two finishes, limit accessories, and let the layout and lighting do the heavy lifting. Simple designs consistently make compact bathrooms feel roomier than busy, over-decorated ones.
Common Mistakes to Avoid
Even homeowners who’ve done their homework on small bathroom renovation ideas tend to trip up on the same handful of things. An oversized vanity is a classic one, eating into the exact walking space you’re trying to protect. Storage is another, often tucked into whatever gap is left rather than planned in from the start.
Lighting gets underestimated too. A dim, flat room will always feel smaller than it actually is, and dark colour schemes only close the space in further. Ventilation is easy to forget, right up until mould turns up a few months later, and it’s worth sorting power outlets early. Running short on points for a hairdryer or heated towel rail is the kind of thing nobody thinks about until the tiling is already down.

| Cleaning | Fewer corners, easier upkeep | Rim and tub need regular scrubbing |

| Space needed | Minimal footprint with glass screens | Larger footprint required |
How Much Does a Small Bathroom Renovation Cost in Auckland?
Costs vary from job to job, so rather than quote a figure that won’t apply to your home, it’s worth knowing what drives the price: bathroom size, whether plumbing needs relocating, waterproofing under the Building Code, your choice of tiles and fixtures, labour, and any custom cabinetry.
Our bathroom packages cover a range of budgets, including options suited to compact spaces.
Why Professional Planning Makes a Difference
A well-planned renovation comes down to more than good taste. It means a layout that works for your household, compliance with the Building Code, waterproofing done the first time properly, and a finish that lasts. Cutting corners on any of these tends to cost more to fix later.
We’ve worked through this exact challenge with plenty of Auckland homes. See some of those transformations in our before and after gallery.
Wherever you’re based, we bring the same approach to small bathroom renovations, with dedicated teams covering North Shore, West Auckland, South Auckland, and East Auckland.
FAQs
What is the best layout for a small bathroom?
Start by leaving the plumbing roughly where it already is, and think twice before adding any wall that isn’t earning its place. Beyond that, it really comes down to legroom, having enough clearance to move between the shower, vanity, and toilet without bumping elbows every morning.
Can you fit a bathtub in a small bathroom?
Yes, though a slimline or corner bath works better than a standard tub. If space is genuinely tight, a walk-in shower is usually more practical.
What colours make a small bathroom look bigger?
Whites, soft greys, and warm neutrals paired with large-format tiles help the room feel more open, though colour works best alongside a good layout.
How long does a small bathroom renovation take?
Most straightforward projects wrap up within a few weeks, depending on scope and whether plumbing needs to move.
Is a walk-in shower better for a small bathroom?
For most households, yes. It opens up the room visually, is easier to clean, and takes up less space than a bath.
