How Much Does a Kitchen Renovation Cost in Sydney? (2025 Guide)

What Is the Average Cost of a Kitchen Renovation in Sydney?

Kitchen renovation costs in Sydney can vary widely depending on your scope, selections, and suburb. Here’s what to expect in 2025:

• Budget kitchen: $25,000–$35,000

What Factors Influence Kitchen Renovation Costs?

Every kitchen is different. Here are the key cost drivers to consider:

Kitchen Size and Layout Complexity

• Small vs large kitchens: Bigger spaces mean more cabinetry, bench area, and labour.
• Layout: Galley and U-shape are typically more cost-efficient than open-plan reconfigurations.
• Structural changes: Moving walls or services (like plumbing) adds significant cost.

Cabinetry and Joinery Choices

• Laminate vs custom joinery: Laminate is budget-friendly, but custom offers flexibility.
• Flat-pack vs bespoke: Flat-pack can work in tight budgets, but custom suits long-term value.
• Storage extras: Overheads, pull-out pantries, and custom drawers add cost and function.

Benchtop and Splashback Materials

• Laminate: Budget option, from $400/m2
• Engineered stone: Mid-range, from $700/m2
• Natural stone: Premium, $1,200+/m2
• Splashbacks: Tiles are affordable; glass or stone costs more.

Fixtures and Appliances

• Sinks, mixers, ovens, rangehoods: Quality and brand matter
• Integrated appliances: Higher cost but seamless design
• BYO vs supplied: Kastell can supply or install yours

Labour and Trades in Sydney

• Builder-led projects streamline coordination and quality
• Trades include: Electricians, plumbers, tilers, cabinetmakers, painters
• Project management: Budget for prep, site safety, rubbish removal

Common Questions About Kitchen Renovation Costs

Can I live in my home during the renovation?

Yes, in most cases you can stay in your home during the renovation. While there may be some disruption, Kastell can work with you to stage the project in phases or find practical solutions to minimise the impact on your daily routine.

Is it cheaper to renovate or replace my kitchen?

In many cases, making thoughtful updates—like keeping your current layout or upgrading in stages—can be more affordable than completely demolishing and rebuilding your kitchen. It’s all about working smart within your space and budget.
