When working with a small bathroom, every inch matters. With the right design choices, you can transform even the tiniest spaces into functional, stylish retreats that feel much bigger than they are. A well-planned small bathroom expansion focuses on layout, fixtures, lighting, and storage to maximise every square metre without sacrificing comfort or style.
Whether you’re renovating an ensuite or reworking a compact bathroom in a city apartment, these tips will help you make the most of your space, creating a more open, airy, and inviting atmosphere.
Prioritise Functionality and Aesthetics in Bathroom Design
When you’re dealing with a small bathroom, it’s easy to feel like you’re up against a wall—literally. But with the right design approach, a small space can feel much bigger than it is. In my experience, the key to a successful small bathroom design is balancing functionality and aesthetics.
If the bathroom is only practical but feels cramped, it’s not going to be the relaxing space you’re after. On the flip side, a bathroom that’s beautiful but impractical can lead to frustration.
The Power of Purposeful Layout
One of my favourite tricks to maximise space is designing a layout that feels intuitive and seamless. For example, in a recent job, we had a client in a tiny apartment in South Melbourne. They needed a small bathroom renovation but wanted it to feel open and airy. Instead of using bulky fixtures, we stuck with compact, space-efficient choices like a wall-hung toilet and a floating vanity. We positioned them so that there was an uninterrupted flow of space. It made all the difference. Not only did the room look bigger, but it also made the space feel more functional for their daily needs.
Think about your bathroom as a series of zones, each with its own function. The layout should reflect that. The key is to arrange items in a way that supports how you use the space, like keeping the toilet and shower apart to create a sense of balance. And don’t forget about flow—being able to move around easily in a small bathroom is a must.
Clever Mirror Usage: The Secret to Spaciousness
I’ve always been a big fan of mirrors in small spaces—more than just for checking your reflection. In fact, mirrors are one of the easiest and most effective ways to create the illusion of space. It’s like an optical illusion that fools the eye into thinking a room is bigger than it really is.
The Power of Large Mirrors
For instance, a few years ago, I worked on a bathroom in a small two-bedroom townhouse in Toorak, Melbourne. The challenge was to make the tiny ensuite feel less claustrophobic. After considering the layout and fixtures, I suggested using a large wall-to-wall mirror above the vanity. It completely transformed the space. Not only did it reflect light throughout the room, but it also doubled the visual space. Suddenly, the bathroom felt like a spa instead of a cramped box.
If you’re working with limited space, large mirrors that span the entire vanity or even the entire wall are a game-changer. They reflect both light and the room itself, which opens it up and makes it feel expansive.
Frameless and Backlit Mirrors: A Modern Approach
One design element that always works well in small bathrooms is frameless mirrors. These sleek, minimalist mirrors blend effortlessly into any design. There’s no bulky frame to detract from the space, and they create a clean, open look. Plus, the lack of a frame makes them feel like an extension of the wall, rather than an object taking up space.
I’ve also started using backlit LED mirrors in many of my projects. Not only do they add a soft, ambient glow perfect for a night-time bath, but they also contribute to the modern, airy feel of the space. The light from the mirror reflects off the walls, giving the illusion that the bathroom is both brighter and bigger.
Mirrored Cabinets: Practical and Stylish
For those looking to combine storage and style, mirrored cabinets are an excellent option. I installed one in a recent renovation project in Fitzroy. It served two purposes: reflecting light to enhance the sense of space while also concealing toiletries and other bathroom essentials. These mirrors help hide the clutter and still give the bathroom that open, fresh vibe. And because they can be recessed into the wall, they save even more space.
Strategic Placement for Maximum Effect
In a small bathroom, placement is everything. I always advise placing mirrors across from windows or light sources. This way, they reflect natural light, making the room feel brighter and more expansive. But be careful—too many mirrors can feel overwhelming. Focus on strategic placement rather than crowding the room with reflections.
Strategic Lighting: A Game-Changer for Small Bathrooms
If mirrors are the secret to visual space, lighting is the magic trick. The right lighting can make all the difference between a bathroom that feels dark and cramped and one that feels open and airy.
Layered Lighting to Maximise Ambience
In my opinion, layered lighting is a must in any bathroom, but especially in small spaces. A combination of ambient, task, and accent lighting is the best way to create depth and dimension. It’s also the key to functionality. I remember working on a job in Richmond where the bathroom had limited natural light. To compensate, we used recessed lighting in the ceiling to provide uniform brightness. We also added wall sconces beside the mirror for task lighting, which is perfect for shaving or makeup application. The final touch was accent lighting under the vanity and around the baseboards, giving the space an extra glow.
Choosing the Right Light Fixtures and Bulbs
The fixtures and bulbs you choose can play a massive role in your bathroom’s feel. I’m a big advocate for LED fixtures. They’re energy-efficient, last longer, and stand up well to humidity. For small bathrooms, dimmers are also a great choice. I once installed a dimmer system in a Melbourne CBD apartment bathroom to create soft lighting for a relaxing bath and bright light for daily grooming. It’s all about versatility.
Maximising Natural Light: The Gold Standard
Incorporating natural light can truly elevate a bathroom. Even in a small apartment, strategic use of windows or skylights can make a bathroom feel expansive. But in a city like Melbourne, privacy is often a concern. That’s where textured glass or frosted windows come in handy. You get the light without compromising your privacy.
Space-Saving Sink and Vanity Solutions
When working with small bathrooms, the fixtures you choose play a huge role in maximising space. One of the biggest space consumers in any bathroom is the vanity. From my experience, minimising bulky vanities has often been the most effective way to create an open, airy feel in a small bathroom. It’s all about being smart with your design choices without compromising on functionality.
Top Space-Saving Sink and Vanity Options
| Vanity Type | Benefits | Ideal for | Example Project |
| Floating Vanities | Wall-mounted, creates the illusion of more floor space, modern aesthetic | Small bathrooms, modern designs | Installed in a small studio apartment in Docklands with hidden storage |
| Pedestal Sinks | Sleek, classic, space-efficient, no visual clutter | Vintage charm, minimalist bathrooms | Added to a guest bathroom in Malvern for a vintage feel, with wall-mounted shelves for extra storage |
| Corner Vanities | Perfect for awkward spaces, maximises corner areas | Bathrooms with odd shapes or angular layouts | Remodelled a Melbourne townhouse bathroom with a corner vanity that fit seamlessly into a tight corner |
Floating Vanities: A Modern Space-Saver
Floating vanities are one of my favourite space-saving solutions. These wall-mounted designs not only help create the illusion of more floor space but also bring a sleek, modern touch to any bathroom. I remember installing one in a compact ensuite in Docklands. The room had limited space, and a traditional vanity would have made it feel cramped. The floating vanity, custom-designed with a slim profile, provided hidden storage while making the space feel more open. The best part? The floor underneath remained unobstructed, enhancing the sense of space.
Pedestal Sinks: Timeless Simplicity
Pedestal sinks are a classic choice for small bathrooms, and I’ve used them in many renovations over the years. Their minimalist design makes them a great fit for tight spaces without overwhelming the room. I recently added a pedestal sink to a tiny guest bathroom in Malvern, where the client was after a vintage charm. The pedestal fit perfectly, though the lack of built-in storage was a consideration. Luckily, the client was happy to add compact, wall-mounted shelves for extra storage. Pedestal sinks are ideal if you don’t mind getting creative with storage solutions.
Corner Vanities: Making Use of Awkward Spaces
For bathrooms with odd layouts or tricky corners, corner vanities are an absolute game-changer. I tackled a small remodel in a Melbourne townhouse, where the bathroom had an angular design. A traditional vanity would have blocked the door, but a corner vanity fit the bill perfectly. It maximised space and added character to the room. The key is to choose a corner vanity with rounded edges, as sharp, boxy designs can make the room feel smaller.
By incorporating these space-saving solutions, you can maximise the functionality of your bathroom without compromising on style. Whether you choose a floating vanity, pedestal sink, or corner unit, these clever design elements can make a world of difference in smaller spaces.
Shower Design: Make the Most of Every Square Inch
Now, let’s talk about showers—one of the most important, space-consuming elements in any bathroom. The right shower design can transform the space, making it feel less cramped while still being functional.
Glass Shower Doors and Walk-In Showers
If you’re still using shower curtains, it’s time to rethink your approach. Frameless glass shower doors are a must-have for any small bathroom remodel. The clear glass creates an uninterrupted visual line, making the room appear more open. In a recent job I did in a small apartment in St Kilda, we replaced the traditional shower curtain with a frameless glass door. The result was incredible—it not only let more light in but also visually expanded the space.
Walk-In Showers: Sleek and Space-Efficient
If you’re working with a bathroom that has a small footprint, a walk-in shower could be a great way to reclaim space. I did a small bathroom renovation in a Victorian terrace house in Richmond, where we swapped out a bulky tub for a sleek, modern walk-in shower. The result was a bathroom that felt vastly bigger and more functional. It wasn’t just about saving space—it was about streamlining the bathroom’s overall design. Walk-in showers can be framed by glass walls or even a simple shower screen to keep the space looking open.
Sliding Shower Doors: Space-Saving Innovation
Another design I’ve used for small bathrooms is sliding shower doors. They take up less space because they don’t swing open, which can often be a problem in tight bathrooms. I installed a sliding door shower in a small studio in Prahran, and the client loved how easy it was to access the shower without having to navigate around a hinged door. Sliding doors can be a lifesaver in compact bathrooms, allowing you to maximise space without losing functionality.
Shower Niches: Storage Without Sacrificing Space
When it comes to storage in the shower, I recommend shower niches. Built directly into the wall, they offer a clean, functional storage solution without taking up additional space in the shower area. I recently designed a bathroom in a narrow Fitzroy apartment, and we incorporated a recessed shower niche for storing toiletries. The niche not only saved space but also added a modern, sleek look to the bathroom. No more cluttered shower caddies or bulky shelves!
Tile Selection and Layout: Key to Visual Expansion
The tiles you choose for your bathroom, as well as how they are laid out, can have a massive impact on the room’s perceived size. Small bathrooms can quickly feel cramped if tiles are chosen without considering the space. From my experience, large format tiles paired with light colours are an effective combination for making a small bathroom feel bigger and more open.
Top Tile Selection and Layout Strategies for Small Bathrooms
| Tile Solution | Benefits | Ideal for | Example Project |
| Large Format Tiles | Fewer grout lines, seamless, reflective of light | Small bathrooms needing a cohesive, open feel | Installed in a bathroom in Carlton to create a seamless look |
| Vertical Tiles | Creates the illusion of height, adds a sense of space | Bathrooms with low ceilings | Used in Abbotsford to give the bathroom a taller, more expansive feel |
| Monochromatic Palette | Unifies the space, eliminates visual clutter | Small spaces that need a streamlined design | Created a soft grey colour scheme in Brighton for a larger feel |
Large Format Tiles for Seamless Flow
One of the most effective ways to make a bathroom feel larger is by using large format tiles. The fewer grout lines you have, the more expansive the room appears. I recently worked on a project in Carlton where we installed large rectangular tiles on both the floors and walls. This approach helped minimise grout lines, creating a seamless look that made the space feel more unified and less fragmented. The bonus? The large tiles also reflected more light, brightening the room and contributing to the open, airy feeling.
Vertical Tiles and Light Colours for Bathroom Walls
For bathrooms with low ceilings, vertical tiles can be a game-changer. I’ve used this technique in many small bathrooms to create the illusion of height. In a recent remodel in Abbotsford, we decided to install rectangular tiles vertically, which made the ceiling feel higher and the entire room appear taller and less cramped. It’s a simple trick that adds dramatic effect without compromising the overall aesthetic.
Monochromatic Palette: Unify the Space
Another strategy I swear by for small bathrooms is using a monochromatic colour palette for both the tiles and walls. By sticking to one consistent colour scheme, you can tie everything together and eliminate visual clutter, which often makes spaces feel smaller. In a bathroom renovation in Brighton, we opted for a soft grey colour for the walls and tiles. The result? A streamlined, unified look that visually expanded the space, making the bathroom feel much larger than it really was.
These tile solutions are all about using design tricks to make a small bathroom feel open, bright, and spacious. Whether you’re opting for large format tiles, vertical layouts, or a cohesive monochromatic palette, these strategies will help you create the illusion of a larger space while keeping the design cohesive and stylish.
Maximising Storage in a Small Bathroom
A small bathroom often means limited space for storage, but that doesn’t mean you need to compromise on keeping everything tidy. In my experience, smart storage solutions can make all the difference in ensuring your bathroom feels organised, open, and functional.
Vertical and Recessed Storage Solutions
When it comes to maximising storage in a small bathroom, vertical storage is a game-changer. In one of my recent renovations in North Melbourne, we took advantage of tall, narrow cabinets and installed them beside the sink. These cabinets went all the way to the ceiling, providing much-needed storage without eating up valuable floor space. The beauty of vertical storage is that it utilises the height of your room, freeing up more floor space for other elements, like a larger shower or vanity.
Another great idea is recessed shelving. When you build shelves directly into the wall, you gain storage without impacting the bathroom’s footprint. I did this in a tight bathroom in Fitzroy where we installed a recessed shelf in the shower to store toiletries. The client loved how it kept the space clutter-free while still providing enough room for everything they needed.
Wall-Mounted Fixtures: Save Floor Space
Opting for wall-mounted fixtures is another trick that will make your bathroom feel larger. I often recommend installing wall-mounted sinks or toilets, as they free up space underneath, creating the illusion of more room. In one case, a client in Melbourne had a small ensuite that felt closed in. After swapping their bulky floor-mounted toilet for a wall-hung version, the space immediately felt more open and accessible.
Concealed Storage: Tidy and Efficient
Nothing makes a small bathroom feel crammed faster than visible clutter. That’s why I always recommend concealed storage—whether it’s built-in drawers, cabinets, or baskets. I recently worked on a bathroom remodel in Hawthorn, where we opted for handleless drawers and hidden cabinets under the vanity. This not only streamlined the look but also kept everything organised and out of sight. If you’re dealing with smaller spaces, this type of hidden storage is crucial in keeping the bathroom looking neat and spacious.
Towel Hooks and Staggered Towel Rods
Another small but effective trick is using towel hooks or staggered towel rods instead of bulky towel rails. This allows you to keep towels accessible without taking up extra space. In a recent renovation for a client in Prahran, we installed staggered towel rods in a way that allowed them to hang towels without feeling cluttered. It made a noticeable difference in how spacious the bathroom felt, while still offering ample storage for towels.
Door Alternatives: Creating an Open Bathroom Layout
In a small bathroom, traditional swinging doors can be a space hog. Over the years, I’ve found alternatives like sliding doors and pocket doors to be fantastic solutions. These options not only help maximise the available space but also add a touch of modern style.
Sliding and Pocket Doors for a Spacious Feel
Sliding doors are a great solution, especially if you’re dealing with a bathroom that’s long and narrow. I recently completed a project in Melbourne’s CBD where we replaced a hinged door with a sliding door for the bathroom. The result was a vastly more open feel. There’s no worry about the door swinging into your space, which can often block access to other areas in the bathroom.
For even more flexibility, pocket doors are another great choice. These doors slide into the wall, completely disappearing when open. I’ve used this in several of my projects where every square inch counts. A pocket door to the bathroom makes it feel like the room is more connected to the rest of the home.
Switching Door Swing: Simple Yet Effective
If sliding or pocket doors aren’t an option, consider switching the swing direction of your existing door. This can often solve layout issues, especially if the door swings out into a hallway or takes up valuable floor space. I did this in a small unit in Richmond, where the original door swung into the bathroom, blocking the flow of movement. By switching the swing direction, we immediately created more space and improved the room’s functionality.
Bathroom Renovation Tips: Transform Your Space with Style
If you’re planning to renovate your small bathroom, there are a few key strategies I always recommend to ensure the space feels larger and more functional without breaking the bank.
Smart Planning for a Successful Small Bathroom Remodel
A successful small bathroom renovation begins with careful planning. When I renovated a tiny ensuite for a client in Malvern, we started by evaluating how they used the space. Did they need more storage? Was the layout creating any awkward traffic flow? We considered these factors before choosing fixtures and finishes. Plan your bathroom layout meticulously so that each element, from the sink to the shower, is positioned thoughtfully to maximise space.
Go for Multi-Functional Furniture
When space is limited, multi-functional furniture is your best friend. Space-saving bathroom furniture, like mirrors with built-in storage or vanities with hidden compartments, offers both functionality and clever design. A well-designed multi-functional vanity can save both floor space and clutter, creating a streamlined aesthetic.
I worked on a project in an apartment in Fitzroy, where we installed a vanity with built-in storage. The unit was compact but offered hidden compartments for towels and toiletries. The minimalist design meant that it blended perfectly into the modern décor, and the lack of visible clutter made the bathroom feel much more spacious.
Don’t Overcrowd the Space
In my experience, the key to a great small bathroom design is restraint. Avoid the temptation to fill every inch with decorative items. Instead, focus on clever storage and functional fixtures that double as design elements. Minimalist bathrooms are not only stylish but also help the space feel uncluttered and more open. I did a minimalist remodel in a small apartment in Southbank, where we kept the design to a few simple elements: a floating vanity, large mirrors, and subtle accents, and the result was a spacious, calming oasis.
