Bathroom Renovation Cost Perth 2025 — What to Budget

A bathroom renovation is one of the most popular home improvements Perth homeowners undertake — and one of the most variable in cost. The difference between a basic refresh and a full luxury renovation can be $30,000 or more. Understanding what drives the cost helps you plan a realistic budget before approaching tradies.

Basic Refresh — $5,000 to $10,000

A basic bathroom refresh replaces fixtures and fittings without moving plumbing or structural elements. This might include a new vanity, toilet, shower screen, tapware, and a fresh coat of paint — but keeping the same tile layout and plumbing positions. It's the most cost-effective way to modernise a tired bathroom, and many Perth homeowners are surprised at how different a bathroom can look with updated fixtures alone.

Mid-Range Renovation — $15,000 to $25,000

The mid-range bracket typically involves a full strip-out and retile, new waterproofing, new fixtures throughout, and potentially some changes to the layout. New floor and wall tiles, a freestanding or built-in bath, frameless shower screens, and quality tapware all sit comfortably in this budget. This is the most common spend range for Perth's established suburbs where homes are being updated rather than starting from scratch.

Full Luxury Renovation — $30,000 and Above

Luxury bathroom renovations involve premium materials — natural stone tiles, bespoke cabinetry, heated floors, premium brands like Astra Walker or Brodware tapware, and potentially relocating plumbing. Custom features, larger footprints, and high-specification finishes push costs upward. For a premium ensuite in a high-value Perth home, budgets of $40,000–$60,000 are not unusual.

What Drives Bathroom Renovation Costs in Perth

• Size: larger bathrooms require more tiles, more waterproofing, more fixtures.
• Tile selection: the difference between budget and premium tiles is significant — and large-format tiles require more labour to lay correctly.
• Waterproofing: non-negotiable under WA building code. Quality waterproofing adds to cost but protects your home.
• Plumbing changes: moving drains or supply lines adds plumbing costs and may require structural changes.
• Labour: Perth trades are in demand — expect to wait for quality tradies and budget for market rates.

Tips for Saving on a Perth Bathroom Renovation

Keep plumbing in the same position to avoid major pipe work costs. Choose mid-range fixtures that look premium — many Perth suppliers stock excellent mid-range options. Buy tiles through a trade account if possible. Get at least three quotes from registered builders and tilers. And build in a contingency of 10–15% for unexpected issues like water damage found during the strip-out.
