Small bathrooms are a reality in a lot of Perth homes, especially in newer suburbs where block sizes have shrunk. But small doesn’t have to mean cramped, dark, or dated.
With the right layout, tile choices, and a few smart design moves, a 3–4 m² bathroom can genuinely impress. Here’s a detailed guide from Tiles Solutions WA, a licensed Perth tiler who’s fitted out hundreds of them.
Best Small Bathroom Layouts for Perth Homes Under 5 m²
Layout is everything in a small bathroom. Get this wrong and no amount of nice tiles will save it.
Wet Room Design — No Shower Screen, More Space
A wet room (no shower screen, fully tiled floor-to-ceiling, drain in the floor) is one of the best ways to gain visual space. Removing the screen entirely makes the room feel immediately bigger.
Works best when:
- Floor area is under 4 m²
- Ventilation is adequate
- Waterproofing covers the entire bathroom floor (required under AS 3740 for WA wet areas)
Corner Shower for Tight Floor Plans
If you need a screen, go corner. A corner shower with a pivot or sliding door takes up significantly less floor space than a mid-wall configuration. 900x900mm corner units are the standard starting point for Perth small bathrooms.
Limited Space Small Bathroom Designs with Shower
When space is genuinely tight, every decision matters:
- Go vertical — tile to ceiling to draw the eye up
- Use a wall-facing shower configuration to maximise remaining floor area
- Install a recessed niche shelf instead of a protruding corner caddy
- Choose a sliding door over a hinged one — saves around 300mm of swing clearance
Shower and Bath Combo — When It Works in Small Bathrooms
A bath/shower combo over a standard tub can work if:
- It’s the only bathroom in the home (families often need a bath option)
- The room is at least 1800mm wide
If it’s a second bathroom or ensuite, skip the bath. It usually just eats floor space without getting used.
Tile Tricks That Make Small Bathrooms Feel Bigger
Tiles are your most powerful design tool in a small bathroom.
Large Format Tiles — Fewer Grout Lines, More Visual Space
This is probably the single biggest design shift in Perth bathrooms over the past five years. Larger tiles mean fewer grout lines, and fewer grout lines mean a cleaner, more open visual.
| Tile Size | Grout Lines Per m² (Approx) | Visual Effect |
| 200x200mm | ~25 | Busy, enclosed |
| 450x450mm | ~5 | Cleaner, more open |
| 600x600mm | ~3 | Very open, modern |
| 600x1200mm | ~2 | Premium, spacious feel |
Note: Large format tiles need a flatter, better-prepared substrate. More labour upfront — but genuinely worth it in a small bathroom.
Light Colours and Vertical Tile Stacking
- Light colours (whites, soft greys, warm creams) reflect light and make the room feel larger
- Vertical stacking of rectangular tiles draws the eye upward, increasing perceived ceiling height
- Matt vs gloss: Gloss tiles reflect more light but show water marks readily. Matt tiles look more contemporary and are easier to maintain day-to-day
Rectified Tiles for Ultra-Thin Grout Lines
Rectified tiles are machine-cut to precise dimensions, so they can be laid with 2–3mm grout joints instead of the standard 5mm+. In a small bathroom, thinner grout lines mean less visual noise — which translates to a more spacious feel.
Small Ensuite Ideas — Making Every Centimetre Count
Ensuites are often the tightest bathrooms in Perth homes. These ideas are built specifically for compact ensuites.
Floating Vanity and Wall-Hung Toilet — Saving Floor Space
Both of these free up floor space visually and practically.
- Floating vanity: 450–600mm depth is standard; nothing on the floor means more visible floor area and easier cleaning underneath
- Wall-hung toilet: Cistern sits in the wall cavity, freeing up approximately 150mm of floor space compared to a floor-mounted unit — and you can adjust the pan height to suit
Recessed Shelving Instead of Protruding Cabinetry
Instead of a wall cabinet that protrudes into the room, cut into the wall cavity and install a recessed niche. This gives you storage without using any floor space at all. Standard niche depth is 100–150mm. This is more than enough for toiletries and accessories.
Mirror Strategies for Doubling Visual Space
Mirrors are probably the cheapest way to make a small bathroom feel bigger:
- Full-width mirror above vanity — edge to edge across the whole wall
- Shaving cabinet with mirrored door — hidden storage with the same visual benefit
- Floor-to-ceiling mirror panel on one wall — creates a near-doubling effect in very tight spaces
Ensuite Bathroom Ideas Worth Adapting for Compact Spaces
Some of the best small bathroom inspiration comes from boutique hotel ensuite design. Here’s what actually translates well to Perth residential:
Open Shower with Feature Tile Wall
A frameless walk-in shower with one feature tile wall is the most popular look in Perth ensuites right now. In a small space, one strong focal point distracts from the room’s size.
Feature tile ideas that work in compact Perth bathrooms:
- Fluted (ribbed) tiles in a warm neutral
- Zellige-look tiles in a muted terracotta
- Veined marble-look slab format
- Herringbone pattern in a contrast shade
Herringbone Floor Tiles for a Premium Look
Herringbone adds texture and interest without making a small bathroom feel busier. Works especially well in smaller formats (75×300 or 100x200mm range) in a neutral tone. It’s one of those patterns that’s been around forever because it keeps working.

Frequently Asked Questions — Small Bathrooms in Perth
What is the minimum bathroom size with a shower in WA?
Under the National Construction Code (as adopted in WA), the minimum shower cubicle size is 900x900mm internally. There’s no mandated minimum overall bathroom size, but practically speaking, anything under 2.5 m² becomes very difficult to make functional.
What tiles work best in a small bathroom?
Rectified large format tiles in a light neutral are the best all-round choice. If you want character, use a feature tile on one wall only, contrast without overwhelming the space.
How long does a small bathroom renovation take in Perth?
Typically 2–3 weeks for a full small bathroom renovation with a professional crew:
- Demolition: 1–2 days
- Waterproofing and cure time: 2–3 days
- Tiling: 2–4 days
- Fixtures, plumbing and finishing: 2–3 days
Add extra time for custom tile orders or if waterproofing remediation is needed.
