Cost estimates only: Any building or upgrade figures in this guide are indicative, not fixed prices or quotes. Costs and inclusions vary by project, supplier, location and time. Confirm current written prices and specifications directly with your builder, suppliers and relevant trades.

Key Takeaways
  • Appliance choices (600mm vs 900mm, gas vs induction) affect cabinetry layout and must be decided early
  • 900mm appliances provide more cooking space and a premium look but cost more in materials and cabinetry
  • Induction cooktops are efficient, fast and easy to clean; gas availability for new builds now depends on the jurisdiction and project
  • Integrated appliances (dishwasher, fridge) create a seamless look but cost more than freestanding
  • Appliance decisions affect services — induction needs an appropriately designed electrical supply, while gas requires a permitted and available gas connection

Kitchen appliance choices affect more than just cooking — they influence cabinetry layout, plumbing, electrical and your overall kitchen budget. Deciding on appliances early (ideally before your kitchen selection appointment) ensures your kitchen is designed around your cooking needs and avoids costly layout changes later.

600mm vs 900mm Appliances

The width of your oven, cooktop and rangehood — 600mm (standard) or 900mm (premium) — is one of the first appliance decisions. This affects cabinetry width, bench space allocation and overall kitchen proportions.

  • 600mm — standard inclusion in most project homes; adequate for most families; standard cabinetry
  • 900mm — more cooking space; premium look; requires wider cabinetry; costs more in both appliance and cabinetry
  • Consider 900mm if — you cook frequently, have a large family, entertain often, or want a premium display-home look
  • Cost difference — 900mm appliances typically add $1,000–$3,000+ plus cabinetry modifications

Gas vs Induction vs Electric Cooktops

  • Gas — visible flame and compatible with all cookware, but a new gas connection must be permitted and available for the project; restrictions apply to many new developments in the ACT and specified/new Victorian homes
  • Induction — energy-efficient; fast heating; safe (no open flame, surface stays cool); easy to clean; requires magnetic cookware; needs heavy-duty electrical circuit
  • Electric (ceramic) — affordable; slower than gas or induction; retains heat after turning off; gradually being replaced by induction

Note

Tell the builder your preferred cooktop early so the electrical and cabinetry design can suit the selected appliance. Induction circuit requirements depend on the appliance and installation design, so the electrician should size the supply from the manufacturer specification. If you are considering gas, first confirm that a new gas connection is legally permitted and available for your project; ACT and Victorian new-build restrictions can apply.

Built-in vs Freestanding

  • Built-in oven — sits in a cabinet at eye or bench height; premium look; typically paired with a separate cooktop
  • Freestanding oven — oven and cooktop combined in one unit; sits on the floor; more affordable; common in standard inclusions
  • Integrated dishwasher — hidden behind a cabinet door panel; seamless look; costs more than freestanding
  • Freestanding dishwasher — visible as a standalone appliance; more affordable
  • Integrated fridge — hidden behind cabinet panels; premium look; expensive; requires specific fridge models

Other Appliance Decisions

  • Rangehood — ducted (vents outside, more effective) vs recirculating (filters and returns air); 600mm or 900mm to match cooktop
  • Microwave — built-in (cabinet housing), drawer (under-bench), or freestanding (benchtop)
  • Dishwasher — check if included as standard; upgrade to quieter or integrated model
  • Coffee machine — plumbed-in espresso machine (requires water connection) or benchtop model
  • Wine fridge — under-bench or tall cabinet; requires power and ventilation
  • Pyrolytic oven — self-cleaning function; premium upgrade
Example Appliance Upgrade Costs

Pyrolytic oven (self-cleaning)$300–$800
Rangehood upgrade (ducted)$200–$600

Questions to Ask Your Builder
  • Does the builder include 600mm appliances as standard, and what's the cost to upgrade to 900mm?
  • If I choose induction, does the builder include the heavy-duty electrical circuit?
  • Can I supply my own appliances, or must I choose from the builder's range?
  • Is an integrated dishwasher included, or is that an upgrade?
Common Mistakes to Avoid
  • Not deciding appliances before the kitchen appointment — cabinetry is designed around them
  • Choosing induction without confirming a heavy-duty electrical circuit is included
  • Forgetting that 900mm appliances require wider cabinetry — the cost isn't just the appliance
  • Not checking whether a rangehood is ducted or recirculating — ducted is more effective
Builder Tips
  • Decide appliances before the kitchen appointment — they affect cabinetry, plumbing and electrical
  • Induction requires a dedicated heavy-duty circuit — tell your builder early so it's planned
  • 900mm appliances provide a premium, display-home look — worth it if you cook frequently
  • An integrated dishwasher ($500–$1,500 upgrade) creates a seamless look — popular in display homes
