Key takeaways
- What you will pay: Compact 4 to 6-tray combi ovens typically list from $6,000 to $15,000, 10-tray workhorses from $12,000 to $25,000, and 20-tray floor units from $25,000 to $42,000 or more.
- Boiler versus injection: Boilerless direct-injection ovens cost less, heat faster, and need less descaling, while boiler-based units deliver more consistent steam at a premium.
- Site readiness matters: Most 10-tray and larger ovens need three-phase power, plus a treated water supply and drainage, so confirm your site before you commit.
- Running costs count: Budget roughly $800 to $2,500 a year for servicing, water filtration, and consumables on top of the price tag.
- Why now: With chefs in national shortage, a programmable combi that logs recipes and standardises output helps a kitchen do more with fewer skilled hands.
A combi steam oven is often the single most expensive item in a commercial kitchen, and also the most versatile. It roasts, steams, bakes, poaches, and regenerates in one cabinet, replacing several pieces of equipment and freeing bench and floor space. But the price range is wide and the running costs are real, so buying well means matching size, steam system, and power to your kitchen before you compare quotes. This guide sets out what combi steam ovens cost in Australia in 2026 and the specs that change the number.
Why combi ovens suit Australian kitchens
Australian food service is large and under pressure. The sector turned over $66.273 billion in the year to June 2025, according to ABS data reported by Restaurant and Catering Australia, and the restaurants industry alone spans nearly 29,765 businesses worth around $26 billion, per IBISWorld. Yet staffing is the constant headache: Jobs and Skills Australia records about 966,000 people employed in accommodation and food services as at August 2025, and its Skills Priority List continues to flag chefs as in national shortage.
That labour squeeze is where a combi earns its keep. A programmable model lets you store recipes, cook to a core temperature automatically, and repeat a result exactly across shifts, so a kitchen leans less on a full brigade of experienced chefs. The precise, hands-off cooking also cuts waste and shrinkage, and HACCP logging gives you a food-safety record without extra paperwork. For many operators the combi is less a luxury than a way to protect output when skilled staff are hard to find.
What a combi steam oven costs in Australia
Price scales mostly with tray capacity and features. Treat the bands below as a price guide for comparison rather than fixed quotes.
| Capacity | Typical price range | Best suited to |
|---|---|---|
| Compact 4-6 tray (benchtop) | $6,000 - $15,000 | Cafes, small kitchens, satellite sites |
| 10-tray (workhorse) | $12,000 - $25,000 | Most restaurants and mid-size kitchens |
| 20-tray (floor / roll-in) | $25,000 - $42,000+ | Hotels, banquet, high-volume production |
| 40-tray (roll-in) | up to ~$52,000 | Catering and central production kitchens |
Within each size, the steam system and controls change the price. Boilerless injection models and manual dial controls sit at the lower end, while boiler-based steam and programmable touchscreens with recipe memory and HACCP logging sit at the top. Gas and electric run at broadly similar prices, though gas boiler models can carry a small premium. Compare current listings across the commercial combi oven and commercial combi steam oven pages to see where real machines land.
The specs that decide the price
These are the features to compare when you request quotes:
- Tray capacity and GN size: Number of trays (6, 10, 20, or 40) and the gastronorm format set output. Size to your covers per service, with a little headroom for growth.
- Steam system: Boiler-based steam is consistent but adds cost and descaling. Boilerless direct injection is cheaper, heats faster, and needs less maintenance. This is one of the biggest price and running-cost levers.
- Energy source and phase: Electric and gas both work, but most 10-tray and larger ovens need three-phase power. Confirm your supply, because upgrading it is a real cost.
- Water treatment: Steam ovens need softened or filtered water to prevent limescale, and units carry WaterMark certification. Budget for a filtration system and periodic cartridge changes.
- Controls and logging: Manual dials keep the price down, while programmable touchscreens add recipe memory, multi-point core probes, and HACCP logging that pays off in consistency and compliance.
- Self-cleaning: Automatic wash cycles save labour and chemical handling, a feature worth the premium in a busy kitchen.
Running costs and site readiness
The price tag is only the start. Plan for these ongoing and installation costs before you sign:
- Servicing: Budget roughly $800 to $2,500 a year depending on usage and water hardness, higher than a plain convection oven because of the steam system.
- Water and energy: A filtration or softening system is close to essential, and steam and three-phase electric or gas make energy a meaningful monthly line.
- Installation: Confirm clearances, ventilation and extraction, drainage, and door swing, plus any gas approval, before delivery day.
A realistic scenario
Consider a 90-seat restaurant in Adelaide replacing a tired convection oven and a separate steamer. A 10-tray boilerless combi around the $18,000 mark does the work of both, freeing floor space and cutting one appliance from the service and cleaning schedule.
Before buying, the operator confirms the kitchen has three-phase power, installs a water filter to protect the steam system, and chooses a programmable model so the kitchen can store recipes and hold quality when the head chef is off. The higher servicing cost is offset by lower waste, faster cooking, and one less machine to maintain. If the menu leans mostly on dry roasting and baking, it is worth weighing a combi against a straight commercial convection oven first, and the commercial combi oven prices buying guide breaks down where each option earns its place.
Frequently asked questions
How much does a commercial combi oven cost in Australia?
Compact 4 to 6-tray combi ovens generally list from $6,000 to $15,000, 10-tray models from $12,000 to $25,000, and 20-tray floor units from $25,000 to $42,000 or more. Boilerless injection ovens and manual controls sit at the lower end, while boiler-based steam and programmable touchscreens sit at the top.
What is the difference between a boiler and a boilerless combi oven?
A boiler-based oven generates steam in a dedicated tank for very consistent output, but costs more and needs regular descaling. A boilerless oven injects water directly onto a heat source, which is cheaper, heats faster, and needs less maintenance, at some cost to steam consistency.
Does a combi oven need three-phase power?
Most 10-tray and larger combi ovens need three-phase power, and many also need a treated water supply and drainage. Confirm your site can supply all three before you commit, because upgrading the electrical supply is a significant added cost.
What are the running costs of a combi steam oven?
Budget roughly $800 to $2,500 a year for servicing depending on usage and water hardness, plus water filtration cartridges and the energy the steam and heating draw. A filtration or softening system is close to essential to protect the oven from limescale.
What matters most
A combi steam oven is a kitchen-defining purchase, so match it to your operation before you shop on price. Size the tray capacity to your covers, choose the steam system that suits your maintenance appetite, and confirm your site can supply the power, water, and drainage the oven needs. Weigh the price tag against servicing, filtration, and energy across the oven's life, and lean toward programmable controls if skilled staff are scarce. Get the fit right and a single combi can carry a kitchen for a decade.
