Making the Switch: Practical Layout Tips When a Combi Oven Replaces Two Older Appliances
Replacing two older appliances with a single combi oven can free up valuable floor space, reduce the number of cooking steps and simplify the kitchen brigade’s workflow. But the swap is rarely a straight “take one out, put one in” job. A combi oven brings different service requirements, different clearances and a different rhythm to the pass. For NSW cafés, restaurants, bakeries, pubs, clubs and catering kitchens, the layout decisions made before installation often determine whether the new unit feels like an upgrade or a daily frustration. The following practical tips can help you organise the change without disrupting service or compromising safety.
Measure the True Footprint and Service Requirements Before You Move Anything
Start by measuring the old appliances properly — not just their external dimensions, but the clearances they were given, the space needed to open doors and pull out trays, and the route used to move them in and out. A combi oven may have a similar width to one of the old units, yet the door swing, handle projection and service access can demand more room than expected. Measure doorways, corridor widths and any tight corners between the delivery entrance and the final position. In older NSW kitchens, a metre-wide passage can quickly become a half-metre problem once packaging and pallet trucks are involved.
Next, confirm the services the chosen combi oven requires. Rather than assuming the old connections will suit, check the manufacturer’s specifications for power, water, drainage, gas (if applicable) and ventilation. A combi oven often needs a water supply and a suitable drain, and the existing plumbing may not be in the right place or may not have the capacity the new unit expects. Electrical circuits also deserve a careful review: two older appliances may have been on separate circuits, while the combi may need a dedicated supply. Engage a licensed electrician and plumber early so that any switchboard, isolation valve or floor waste work is planned rather than discovered on installation day.
Think about what happens when the old appliances come out. Removing a convection oven, steamer or fryer can leave behind stained flooring, redundant pipework, old isolators and gaps in the wall or bench. Those “making good” tasks take time and should be scheduled before the new unit arrives. If the combi oven will sit on a plinth or mobile stand, check the floor level and load-bearing capacity in that spot. Also confirm that the unit’s feet or castors can be adjusted to sit stable and level. A combi oven that rocks or drains poorly because the floor falls the wrong way is a layout problem, not a cooking problem. For operators in Sydney and regional NSW, it also pays to check whether the delivery truck can access the site and whether the unit can be manoeuvred through the building without removing doors or shopfront glazing.
Rework the Workflow, Not Just the Equipment Position
A combi oven changes the way food moves through the kitchen. It can roast, steam, bake, poach and reheat, so the old split between “oven station” and “steamer station” may no longer make sense. Use the replacement as an opportunity to review the whole hot line: where do staff collect trays, where do they load and unload, where do they plate, and where does the pass sit? Position the combi oven so that a cook can open the door, slide out a rack and move food to the pass without crossing another staff member’s path or squeezing past an open dishwasher door. A clear landing space for hot trays is essential — ideally a nearby bench that is not also used for raw prep or service plating.
Keep the combi oven close to the prep area but separate it from cold storage and beverage service. Trays of vegetables, proteins and bakery items should flow from the fridge or dry store to prep, then to the oven, then to the pass. If the new unit is tucked into a corner that forces staff to walk around a fridge or through a waiters’ station, the time savings of combining two appliances will disappear. Also consider the height of the oven and the racks: a unit mounted too low or too high can create lifting and reach issues during a busy service. Check how the door opens and whether a trolley can be parked in front without blocking a walkway.
As you reorganise the line, it is also worth reviewing whether the ice station is still in the right place. A layout change can expose bottlenecks at the drinks station, particularly in cafés, pubs and clubs where staff are constantly moving between the pass, the coffee machine and the bar. If space is being freed up, plan the position of a dedicated Commercial ice machine so that it supports drinks service without forcing staff to cross the cooking zone. The aim is a kitchen where the combi oven, prep benches, refrigeration, dishwashing and beverage equipment all work together rather than competing for the same metre of floor space. Consider a simple walk-through with the head chef and a trusted equipment adviser before finalising the position — it is easier to move a line on paper than after the plumber has connected the drain.
Plan Access, Ventilation and Future Service Around the New Combi
Combi ovens produce heat, steam and moisture, so ventilation and extraction deserve more thought than they often receive. Check whether the existing canopy or extraction system is suitable for the new unit and whether the oven can be positioned under it without blocking filters or fire suppression equipment. In some kitchens, the combi oven may need to sit under a dedicated section of canopy, or the extraction may need adjustment to handle the steam load. Do not assume that because the old appliances sat there, the new one will be fine. Speak to a ventilation specialist or your equipment supplier about the model’s requirements, and confirm that make-up air and grease filter access are not compromised.
Service access is another practical layout issue that is easy to overlook. A combi oven needs space for technicians to open panels, reach components and diagnose faults. If the unit is boxed in by a bench, a wall or a stack of storage crates, every service call becomes more difficult and more time-consuming. Leave the recommended clearances around the unit, and keep the area in front of the control panel clear. If the oven is plumbed in, make sure the isolation valves and drain connection are accessible. The same goes for water filtration: if a filter is fitted, it needs to be reachable for replacement. Photograph the installation once complete and keep the manual, service contacts and any commissioning notes in a known place — future staff and technicians will thank you.
Finally, think about cleaning and daily shutdown. A combi oven may have an automatic cleaning programme, but staff still need access to the door, the drain, the detergent compartment and the control panel. Position the unit so that cleaning cloths, gloves and chemicals can be stored nearby without cluttering the cooking area. Check that the floor around the oven can be cleaned easily and that any drain or floor waste is not covered by a trolley or mat. In shared kitchens, such as clubs and catering operations, label the isolation points and include the combi oven in the opening and closing checklists. A well-planned layout is not just about fitting the unit into the room; it is about making the new appliance safe, practical and efficient for every shift.
