Designing a small bathroom sounds simple until you actually try to fit everything in.

Shower, toilet, vanity, storage… and somehow still make it feel open.

Most people make the same mistake early on. They focus on tiles, colours and fittings before locking in the layout. That’s how you end up with a bathroom that looks good in photos but feels cramped every day.

This guide breaks down small bathroom ideas that actually work in Australian homes, starting with layout first, then design, then the finishing touches.

The 2 Small Bathroom Layouts That Always Work

If you get the layout right, everything else becomes easier.

These are the setups that consistently work in real homes and I have gone with two most common small bathrooms I see in Australian homes. Homes are all super unique but these two layouts are by far the most common examples I get sent.

1. The 2mx2ish Bathroom Layout (Tight but Functional)

This is one of the most common ensuite small bathroom designs I get sent.

Idea of the setup: (This Is The Small Tweak Example)

• Shower in the back corner
• Vanity to one side of the shower not across
• Toilet positioned to one side

Key tip:
For this classic layout that most renovators have or a variation of it, the design keeps the centre open and the screen further back.

With the mirror facing you and the screen set up back it doesn’t feel cramped and gives you the most consistent sizing of each item.

Below is the best version of this we can create based on keeping it all pretty uniform.

Key Improvements

• Elimates hard to clean gap with nib wall (secret internal hidden low niche gives a foot rest or a place to hide bottles)
• Full-height tiling makes the small room feel big
• Slight curve on screen at the base and introduction of strip drains

For subtle changes like this, you can make your small bathroom layout more functional without moving plumbing or getting crazy. This layout is the most functional if you care about all aspects of the room

Option 2 (Medium Change)

If your only real goal is to have a big shower in these types of small bathrooms, let me introduce you to the next style. We call it the toilet wet room.

Again, below is a similar style to the small bathroom layout above. Almost identical in size to the one above. The image after is the finished renovation

The Real Benefit

Coverting a pivot or slider door in a small bathroom like this to a open fixed panel all comes down to your comfort with water. It needs to be expertly put together, but you will have water splash onto the toilet.

If you do not like the idea of water splashing onto a toilet, do not have this small bathroom layout, but if you like the idea of having a huge shower in a small bathroom, this is for you.

I do have a third option which gives a small ensuite, a large shower and a large vanity, but it’s pretty niche. Just email me askthebathroomguy@gmail.com for that info.

2. The Family Small Bathroom

The second most common small bathroom I am sent around Australia looking for advice is the main/family bathroom. Below is the classic example, either all on one wall or a long version.

Measurements for the majority of these spaces are 2.5m Wide x 1.8m Deep (Window Wall)

I will cover the three most popular layout conversions for a small family bathroom

1. The Add A Toilet No Bath Layout

Owner wanting a second toilet in there, how will sacrifice a bath for the toilet and a large shower.

Best setup:

• A walk-in shower or a shower wall equals a big shower
• All on one wall to make the face feel huge
• The toilet is positioned centrally to allow for easy cleaning between the shower and vanity areas

Key tip:
The cleanest look you will ever have for a bathroom is the ALL IN A ROW layout, which is what this is. The toilet in the middle is not for everyone, with some people preferring it behind the door

2. The Wet Room Layout (Big Shower Less Corridor)

I love wet rooms (Tap Here) for a huge breakdown I have done. They are designed to get a big shower in your small bathroom and move the screen from the entrance, which makes the room feel cramped at the entrance.

Best setup:

• A walk-in shower with no in your face screen
• Freestanding or back-to-wall bath for both adult and child use
• Vanity at the entrance of the room to make it feel bigger.

Key tip:
Wet rooms are designed for the homeowner wanting a modern renovation to an older-style home. It is for a family who wants to open up their small space with a large bath and a big shower that caters to different sizes and ages.

3. The Walk-In Layout (No Toilet No Bath)

Finally, we have the simplest concept of the small bathroom. The walk-in shower layout in a small family bathroom is designed for storage.

Best setup:

• Large double vanities or just a large single vanity
• Can be used for tall-boy storage
• Huge shower, but can be converted to a double shower set-up

Key tip:
Walk-in showers are for families or houses looking for tons of storage, less fighting over one basin or a more practical shower set-up for someone who is planning or needing a better entrance to their shower.

Walk-In Shower vs Shower Screen in Small Bathrooms

This is one of the biggest decisions people make.

Walk-in shower

Pros:

• Clean, open look
• No door or frame
• Makes the room feel bigger
• Less parts to break or wear down
• Easier to match into tapware

Cons:

• Water can escape if not designed properly (all comes down to workmanship)
• Needs more space to work well (usually over 1.2m of alcove space to work)
• Usually more expensive to build correctly over half walls

Shower screen/enclosure

Pros:

• Contains water better
• Works in tighter spaces
• More cost-effective

Cons:

• Can feel more enclosed
• Frames can date over time
• Hard to always match modern tapware

What actually works best?

In smaller bathrooms, a fixed glass screen (not fully open, not fully enclosed) is usually the sweet spot.

You get the open feel without water going everywhere. Look at it like this, most well-done open showers should contain about 95% of the water with the other five per cent splashes

Small Bathroom Ideas That Make It Look Bigger

This is where design comes in, but only after layout is sorted.

Use Larger Tiles

Bigger tiles = fewer grout lines = less visual clutter.

This makes the room feel more open, even if the size hasn’t changed.

Wall-Hung Vanities

Getting the vanity off the floor creates visible space underneath.

That small gap makes a big difference in how open the room feels.

Keep Colours Consistent

Too many contrasts can chop the room up visually.

Sticking to a consistent palette helps everything flow.

Use Mirrors Properly

A large mirror isn’t just a design feature; it reflects light and doubles the sense of space.

Lighting Matters More Than You Think

Poor lighting can make even a decent-sized bathroom feel small.

Layered lighting works best:

• overhead lighting
• mirror lighting
• soft ambient lighting if possible

The biggest one with lighting is NATURAL Light, but if that is not possible, look into TRUE LIGHT LEDs, which create the most natural look.

Storage Ideas That Actually Work in Small Bathrooms

Storage is where most small bathrooms fall apart.

Recessed Niches

Built into the wall, so they don’t take up space.

Perfect for showers and above vanities.

Mirrored Cabinets

You get storage and a mirror in one.

Better than a basic mirror in most small bathrooms. The big key for mirror cabinets is that if you buy online, actually check the backing size. Some of them have huge fronts but small square boxes at the back.

Vertical Storage

If you can’t go wide, go up.

Tall cabinets or shelving can add storage without eating into floor space. Tall boy cupboards are what you want if you want to turn your vanity space into actual storage.

HIDDEN STORAGE

In-wall boxes and hidden toilet roll holders are the most modern concept for small bathrooms. CHECK OUT this link here for my huge breakdown of them and where you can buy them.

Mistakes That Make Small Bathrooms Feel Smaller

These are the things that ruin a good layout.

Using Small Tiles Everywhere

It seems logical, but it usually makes the space feel busier and smaller. Use big tiles in big bathrooms, do not make the room feel smaller by a thousand lines.

Poor Layout Planning

Trying to squeeze everything in without thinking about flow leads to awkward spacing and daily frustration. This comes with restraint of wanting to add everything, but being practical about how your bathroom actually functions.

Bad Lighting

Dark corners and shadows shrink the space visually. Opt for the right LED Downlight location

Too Many Design Features

KEEP IT SIMPLE. Ideally, only have one layout in a small bathroom. Too many design features can’t compete. If you spend big money on your vanity or feature tile, make them the star

How Much Does a Small Bathroom Renovation Cost in Australia?

What a Bathroom Renovation Costs in Australia

If you’re planning a bathroom renovation in Australia, one of the first questions is: how much will it actually cost? Here’s a realistic guide based on what I’m seeing across real projects in 2026 heading into 2027

Small Bathroom Renovation Costs $20,000 – $29,995

Includes keeping basic layouts, standard tile sizes (no larger than 600 x 600), mid-range fixtures, and professional fully managed project. Ideal for a simple shower, toilet, and vanity setup, with minimal plumbing changes (think changing mixers standard, replacing galvanised plumbing or adding a toilet non-standard)

Mid‑Range Bathroom Renovation Costs $29,000 – $38,000

This includes everything above, but now we are talking a bath, added brick shelving (niche or half wall), and most likely a custom screen. Perfect for flexibility on layout. This costing is really for a slightly larger room, but more of what you want.

High‑End Bathroom Renovation Costs $35,000+

For me, these types of renovation can be anything but really are for what I call 4 part rooms, bathrooms with a vanity, toilet, bath and shower that is stand-alone. These start higher due to the cost of materials and go from there.

These ranges cover standard layouts, quality fixtures, and professional workmanship. Costs can shift depending on factors like moving plumbing, custom cabinetry, or premium finishes. Focusing your budget on the essentials—layout, waterproofing, and reliable trades—will help you save money without cutting corners.

“Cost ranges can vary by city because of labour and material differences — typically, Perth, Adelaide can be a little bit cheaper than Sydney and Melbourne, but in this current client, the demand is high, and the supply is low.

What I’d Do in My Own Small Bathroom

If I were renovating a small bathroom today, and let’s say it’s a classic family bathroom 2.5m x 1.8m

• Wet room layout with a deep-bricked bath (feels more day spa with a bricked bath)
• Open shower but half screen with lower half wall (easy to clean)
• Go with large-format tiles 1200mm x 600 or porcelain panels
• Duel hand wash and overhead (off a rail)
• Keep the design simple and consistent

Nothing overcomplicated, just a layout that works and finishes that last P.S I am a huge one tile person, which I feel looks the most timeless with the right tile.

Final Thoughts

A small bathroom doesn’t have to feel cramped unless you make it that way. I see it all the time with renovations where something gets put on every wall and you can barely move. If your goal is to fit everything in, that’s fine. But the best advice I can give for any small bathroom design in Australia is to decide what matters most to you, then design the entire space around that.

If you focus on:

• layout first
• smart design choices
• avoiding common mistakes

You can end up with a space that feels bigger than it actually is.
