What is the Average Cost of a Bathroom Renovation in Sydney?
On average, bathroom renovations in Sydney fall into three cost tiers:
Budget Bathroom Renovation ($15,000–$25,000)
- Cosmetic updates and basic layouts
- Entry-level bathroom tiles, fittings, and fixtures
- Suitable for rental properties or budget-conscious renovations
Mid-Range Bathroom Renovation ($25,000–$40,000)
- New tiling, waterproofing, and layout changes
- Mid-range bathroom tiles, tapware, and wall-hung vanity
- Frameless shower screens, floor-to-ceiling tiling
Luxury Bathroom Renovation ($40,000+)
- High-end materials, custom cabinetry, and premium fixtures
- Heated towel rails, underfloor heating, v-groove panelling
- Fully reconfigured layouts or expanded spaces
Small bathroom renovation costs tend to be lower due to reduced labour and materials, but luxury finishes can quickly push up the total. Ensuite renovation costs typically align with mid-range pricing, unless structural changes are involved.

Why Are Bathroom Renovations in Sydney So Expensive?
Several local factors contribute to the higher cost of bathroom renovations in Sydney:
- High Demand for Skilled Trade - Sydney’s renovation boom means trades are booked out, driving up prices due to limited availability.
- Sydney's Cost of Living - The city’s high living costs translate into more expensive insurances and running costs.
- Older Housing Stock - Many Sydney homes have outdated plumbing or hidden damage, requiring costly repairs during renovation.
- Strata & Council Approvals - Additional layers of approval for apartments or structural changes can delay and increase project costs.
- Building Code Compliance – Renovations must meet strict NSW standards, requiring licensed trades and quality materials that cost more, all in accordance with the National Construction Code (NCC).
Location also plays a role — factors like narrow access, parking restrictions, and older building structures in areas such as the Eastern Suburbs or Lower North Shore can add complexity, and therefore time and cost, to the renovation process.
Hidden Costs You Need to Know About
Even the best-planned bathroom renovation budget can be thrown off by unexpected issues:
- Plumbing surprises (e.g. rusted pipes, poor previous work)
- Compliance or approvals especially in apartments
- Structural issues such as water damage, termite damage, or uneven floors
Kastell includes a pre-construction inspection to reduce the risk of these surprises. Learn more on our Pre-Project Planning page.
How to Budget for a Bathroom Renovation (And Stay on Track!)
Smart budgeting isn’t just about setting a number — it’s about knowing where to spend and where to save.
- Get a fixed-price quote to avoid scope creep
- Choose mid-range fixtures for the best balance of cost and quality
- Avoid moving plumbing if your layout already works
- Leave compliance work to professionals — DIY waterproofing can void warranties
