How Much Does a Bathroom Remodel Cost in Sydney in 2026?
The short answer: most Sydney bathroom renovations cost between $25,000 and $30,000, but the range spans from cosmetic refreshes at $5,000–$10,000 to luxury renovations exceeding $60,000. The difference between those two extremes is scope, not just aesthetics.
The Real Cost Range
The average bathroom renovation in Sydney ranges from $15,000 to $35,000, though individual projects often land higher or lower depending on a handful of specific choices. Understanding which tier fits your project prevents the most common problem: discovering halfway through that the budget assumed a different scope than what you’re actually doing.
What Drives the Cost?
The size and complexity of the space matters, but six things account for almost all the variation between a $20k bathroom and a $40k bathroom, and most of them are choices you can control.
Plumbing relocation is the biggest lever. Keeping the shower, toilet, and vanity in their existing positions is the simplest, cheapest approach. The moment plumbing moves — even by 300mm — a full rough-in is required: cutting into floors or walls, relocating waste pipes, extending supply lines. Moving a single fixture typically adds $3,000–$8,000.
Tile selection. Tiles can cost anywhere from $25/m² for basic ceramic to $250/m² for designer Italian porcelain or natural stone. Large-format tiles (600×600mm and larger) also cost more to install because precision and labour time increase.
Fixture quality and finishes. Tapware and fittings vary enormously by brand. A basic set costs $200–$500; designer tapware ranges from $1,000–$3,000+.
Waterproofing and compliance. Waterproofing compliance costs between $1,200–$3,500 in NSW and is not optional. Every wet area must comply with Australian Standard AS 3740.
Hidden costs. Bathrooms in older Sydney homes (pre-1990) often contain asbestos in wall sheeting, floor tiles, or adhesives, adding testing and disposal costs. Water damage, rotted timber, or failed waterproofing from previous work often surfaces once demolition begins.
Labour. Labour typically accounts for 40–50% of total renovation costs, and labour costs have increased 8–10% since 2024 due to strong demand and skilled labour shortages.
The Cost Tiers Explained
Cosmetic Refresh: $5,000–$12,000
New vanity, tapware, accessories, fresh paint, and localized splashback tiling. Plumbing stays untouched. This works for bathrooms that are structurally sound but dated.
Standard Renovation: $20,000–$30,000
Full strip-out with new waterproofing, mid-range standard ceramic tiles, updated modern fixtures (shower screen, toilet, vanity). The existing layout is preserved — no plumbing relocation. This is where most Sydney homeowners land, and it represents good value for a complete refresh.
Mid-Range to Premium: $30,000–$45,000
Higher-quality tiles (large-format porcelain, stone-look), custom or semi-custom vanity, frameless shower screen, heated towel rails, and possible minor layout tweaks. This tier includes the finishes that make a bathroom feel current and well-designed.
Luxury or Structural Change: $45,000–$70,000+
Complete layout overhaul, custom joinery, freestanding bath, underfloor heating, premium natural stone, high-spec tapware, or structural changes requiring engineering. These projects are built around personal use rather than resale value.
What Gets Included at Each Level?
Most bathroom renovations involve the same basic stages: demolition, waterproofing, tiling, fixtures, and finishing. The difference is the quality of materials, the complexity of the work, and whether plumbing or structure is being altered.
Demolition and waste removal typically costs $1,500–$3,500. Waterproofing is mandatory and must be done by a licensed tradesperson. Tiling labour varies enormously with tile selection — standard 300mm tiles are faster and cheaper than large-format sheets. Plumbing and electrical work must be carried out by licensed tradespeople, and compliance certificates are required.
Labour breakdown: Most projects require 120–180 labour hours across all trades for a standard renovation. That includes coordination, project management, and sequential scheduling so plumbing is done before waterproofing, and waterproofing is inspected before tiling.
Hidden Costs and Contingency
Most bathroom renovations hit at least one unexpected cost once demolition starts. It is highly recommended to allocate an extra 10–15% in your budget for unexpected costs. Common surprises include substrate damage requiring structural repair, asbestos requiring professional removal, failed waterproofing from previous work, or plumbing complications in older homes.
Size Matters More Than You Think
Small bathrooms — typically 3–5m² including ensuites — cost between $15,000 and $25,000 for a complete renovation. However, smaller spaces can actually cost more per square metre because fixed costs (plumbing connections, waterproofing setup, electrical work) don’t reduce proportionally with size.
Medium-sized bathrooms (5–8m²) represent most Sydney homes and typically fall into the $20,000–$35,000 range. Large bathrooms exceeding 8m²—often master ensuites with double vanities, freestanding baths, and separate shower zones—cost $35,000 to $50,000+ depending on fixture selection and finishes.
Regional Variation
Prices vary across Sydney. Eastern Suburbs and North Shore labour rates tend to run 10–15% higher than Western Sydney, and older properties in these areas often carry higher hidden-cost risk due to pre-1990 construction standards.
Getting a Fixed-Price Quote
The best protection against budget blowout is a clear fixed-price contract after the design phase is locked. Once materials, finishes, and structural scope are finalized, a licensed contractor should issue a fixed-price quote. If changes come up mid-project, they should be documented as separate change orders with pricing before approval.
