Bathroom renovations for small bathrooms: Practical ideas, layouts and costs in Perth and across WA

Transform your compact bathroom or tiny ensuite into a beautiful, functional space. This expert guide from Joyce Kitchens covers small bathroom ideas, modern bathroom design ideas, materials, costs and a step-by-step renovation process that meets WA standards.

Why small bathrooms deserve big design thinking

Limited square metres don’t have to limit your comfort, storage or style. With compact bathroom design and clever small bathroom arrangements, you can fit more into less—from a wall-hung vanity that frees up floorspace, to a walk-in shower with a frameless screen that makes the room feel bigger. Whether it’s a mini bathroom in an apartment, a small ensuite bathroom, or a small toilet renovation, our Perth-based team designs to the millimetre.

Joyce Kitchens is known for custom cabinetry WA homeowners trust—across bathroom renovations Perth, kitchen renovations Perth, laundry renovations and wardrobes. That whole-home perspective helps us deliver cohesive, space-savvy solutions, from a shaker-style vanity that matches your shaker kitchen to compact storage that flows with your walk-in robe.

Smart layouts for small bathrooms

Small bathroom designs start with traffic flow, door swing, and clearances. Below are proven small bathroom layout options that suit most WA homes.

Best-practice dimensions for compact bathroom design

  • Toilet: 760 mm clear width minimum; 600 mm clear in front.
  • Shower: 900 x 900 mm is comfortable; 1000 x 900 mm if space allows.
  • Vanity: 450–500 mm deep for tight rooms; 600 mm for family bathrooms.
  • Bath: 1500 mm back-to-wall bath fits many small bathrooms.
  • Door: Consider a cavity slider to free up floor area.

Small bathroom layout ideas that work

  • One-wall layout: Toilet, vanity and shower along one wall for maximum circulation.
  • Shower-over-bath: Great bath shower ideas for small bathrooms when the family needs a tub.
  • Niche plus nib wall: Hide the toilet behind a short nib wall and add a recessed shelf.
  • Corner vanity or shallow wall-hung vanity: Improves movement around the room.
  • Walk-in shower with a single glass panel: Less framing = larger feel; suits small bathroom designs with shower.
Definition: Nib wall
A short internal wall (often 900–1200 mm long, 100 mm thick) used to screen a toilet, create a shower shelf, or hide services without enclosing the room.
Definition: Fall to waste
The slope required in the bathroom floor and shower to direct water to the drain. In Australia, waterproofing and falls are designed to meet AS 3740 (Waterproofing of domestic wet areas).

Two quick WA case examples

Subiaco apartment ensuite: We replaced a swing door with a cavity slider, added a 450 mm-deep wall-hung vanity with drawers, and a 1000 x 900 mm hobless shower with a tile-in grate. Result: a small ensuite redo that feels 30% larger.

Baldivis family bathroom: A shower-over-1500 mm bath with a fixed glass panel, recessed shaving cabinet, and mirrored storage. Durable porcelain tiles, brushed nickel tapware and bright LED strip lighting for a small modern bathroom aesthetic.

Materials and finishes that work in small spaces

Every material must handle steam, splashes and daily wear. In WA’s warm climate, UV and heat stability also matter. Below we compare popular vanity benchtop options and outline finishes that visually expand a small bathroom.

Vanity benchtop comparison (space-savvy options)

Feature Porcelain / Sintered Stone Slab High-Pressure Laminate Engineered Stone*
Water & stain resistance Excellent; non-porous; heat tolerant Good; needs care with heat Excellent; non-porous
Visual impact in small bathrooms Large-format slabs reduce grout lines Wide colours; thin profiles look sleek Stone-look patterns; seamless
Maintenance Easy; no sealing Easy; avoid harsh abrasives Easy; no sealing
Indicative cost (WA) $$$ $–$$ $$$
Notes Great for vanities and feature walls Budget-friendly; modern edges *Subject to national engineered stone ban—see note below

*Important WA/Australia note: From 2024–2025, Australian jurisdictions (including WA) have implemented a ban on the fabrication, supply and installation of engineered stone products containing crystalline silica for new projects. Check the latest rules and alternatives with your designer and fabricator. See guidance from Safe Work Australia (nofollow): Engineered stone ban.

Other materials that maximise space

  • Wall-hung vanities and toilets: Elevate sightlines and make cleaning easier.
  • Large-format porcelain tiles: Fewer grout lines = visually bigger room.
  • Light, warm neutrals: Think warm white, light greige; add timber accents.
  • Mirrored storage: Recessed shaving cabinets double as mirrors and storage.
  • Clear frameless screens: Keep the room open; tilt to bathroom designs with shower.
  • Drawer-based vanities: Organised, space-efficient storage compared to doors.

Taps, lighting and ventilation

  • Tapware: Brushed nickel, chrome or matt black; stick to one finish for calm, modern small bathroom designs.
  • Lighting: Layer downlights with sconces or LED strip under the shaving cabinet for soft, shadow-free light.
  • Ventilation: An effective exhaust fan is non-negotiable in small bathroom renovations; consider humidity sensors.

FAQ

What is the best layout for a small bathroom?

The most reliable layouts are one-wall (toilet, vanity and shower aligned), a walk-in shower with a single glass panel, or a shower-over-1500 mm bath if you need a tub. Aim for a 900 x 900 mm shower, 450–500 mm-deep wall-hung vanity, and use a cavity slider to free floor space. Add recessed storage (shaving cabinet, niches) to reduce clutter.

How much does a small bathroom renovation cost in Perth?

As a guide, budget $8,000–$15,000 for a cosmetic refresh, $18,000–$35,000 for a full small bathroom renovation with quality finishes, and $35,000–$60,000+ for premium selections or layout changes. Site conditions, access and selections can move the needle.

Can I fit a bath and shower in a small bathroom?

Yes—use a shower-over-bath with a fixed glass panel, or a compact 1500 mm back-to-wall bath paired with a narrow walk-in shower. A short nib wall can screen the toilet while adding shelf space. Keep screens frameless and finishes light to maintain a spacious feel.

What materials are best for small bathrooms in WA?

Choose moisture-ready options: porcelain or sintered stone for benchtops and feature walls, high-pressure laminate for budget vanities, large-format porcelain tiles, and quality ventilation. Note Australia’s ban on new engineered stone fabrication/supply/installation—confirm current rules and consider porcelain or solid-surface alternatives.

Do I need approvals or specific standards for a bathroom renovation?

Most like-for-like renovations won’t need council approval, but structural changes may require a building permit. Waterproofing must meet AS 3740, plumbing AS/NZS 3500, and electrical AS/NZS 3000 with licensed trades. Refer to HIA or Master Builders WA for guidance and always check local requirements.
