The SMEG Countertop Combi Oven comes first because its listing names real steam-convection modes; the Waring wins for plain commercial baking.
Few listings here are true combi ovens. Only SMEG and Nuwave name steam modes among the commercial-style picks; the Midea and CHEF iQ listings do not. The rest are convection or toaster units. If you want the best commercial combi oven, that narrows the field fast.
None is a full floor-standing combi. These are countertop units. For half-size pans in a restaurant, pick the Waring. For a tiny counter, the Cadco.
Our top picks for Commercial Combi Oven
The SMEG Countertop Combi Oven is the top pick because its listing names steam modes combined with convection and grill. The SMEG listing includes a removable water container. For plain commercial baking, the Waring half-size convection oven wins, and the Cadco suits the tightest counters.
How this guide was researched
No product was handled. The picks come from setting each manufacturer’s listing against the others: wattage, capacity, footprint, weight, controls, steam modes and stated certifications.
Listings cannot show fit, feel or durability, nor how evenly an oven bakes. Treat the ranking as a spec comparison.
8 listings were compared on capacity, item weight, wattage and dimensions. 3 were set aside (1 not what the search asks for and 2 beaten on a listed spec). No product was bought or physically handled: every figure is the manufacturer's listing value. Produced by Cooking Equipment & Food Prep Desk. Editorial responsibility: restaurantweekhawaii.com.

What made the cut
1. SMEG Countertop Combi Oven: steam and convection
1 · Best Overall
Verdict: For a kitchen that wants true steam-plus-convection cooking on a counter; skip it if you need a commercial-rated unit.
- 1 cubic feet Capacity
- 42 pounds Item Weight
- 1800 watts Wattage
- 19.5"D x 19.75"W x 15.5"H Dimensions
Best for Cafes, bakeries or home-style kitchens that need steam and convection in one box
Skip it if You need a commercial-rated unit for daily volume; look at the Waring instead.
What we like
- Combi Convection Steam and Combi Grill Steam modes
- 10 functions and 33 automatic recipes
- Touch LCD, 100-450°F range
What could be better
- No commercial rating stated
- 450°F max, below the Cadco's 500°F
- Door material not stated
Against the next pick: Beats the Nuwave on listed steam modes and a 1 cubic foot cavity; loses on size, since the Nuwave lists 16 quarts in a smaller footprint.
Not stated on the listing: door material type. Also sold as: Pastel Green, Pastel Blue, Cream.
This is the only pick whose listing names combined steam modes: Pure Steam, Combi Convection Steam and Combi Grill Steam. A removable water container is in the box. That is what a combi oven means.
Trade-off first. It is a home-style retro appliance, and the listing does not state any commercial rating or duty cycle. Temperature tops out at 450°F, lower than the 500°F of the Cadco and VEVOR convection units.
The upside is range. The listing gives 10 functions, 33 automatic recipes, a touch LCD, and a 100-450°F span that reaches down to defrost and warming. Three shelves and an enameled tray, perforated tray and two grill racks come with it.
It weighs 42 pounds and measures 19.5 by 19.75 inches on the counter. Capacity is listed at 1 cubic foot, so check pan sizes before buying. The listing does not state a door material. Other colours are sold.

2. Nuwave Combi Steam Oven: steam and sous vide
2 · Best Budget Steam
Verdict: For a small kitchen wanting steam, air fry and sous vide at a lower price; it lists no door style or shelves.
- 16 quarts Capacity
- 21.4 pounds Item Weight
- 1800 watts Wattage
- 14.75"D x 13.88"W x 14.88"H Dimensions
Best for Small cafes or home kitchens testing steam and sous vide
Skip it if You need a rated commercial unit or known shelf count; look at the Waring.
What we like
- Steam ratio adjustable 10-90%
- 50-450°F in 1°F steps
- 21.4 lb, compact 13.88 in width
What could be better
- Door style, shelves and control type not stated
- Not rated commercial
- Preset count inconsistent in the listing
Against the next pick: Beats the Waring on steam and a 21.4 lb weight against 52.6 lb; loses on commercial credentials.
Not stated on the listing: door style, control type, temperature range.
The steam control is the draw. Moisture adjusts from 10% to 90%, and temperature runs 50-450°F in 1°F steps. COMBO mode steams and air fries together.
Gaps first. The listing does not state door style, control type, shelf count or a commercial rating. It is a toaster-oven-class multi-cooker.
Capacity is 16 quarts at 1800 watts, against 1750 watts for the Chef iQ. It weighs 21.4 pounds and is 14.75 inches deep, so it moves easily.
Presets are plentiful, with 120 named in the title and 100 easy-cook presets plus 50 memory slots in the specs. The two counts differ in the listing. The listing says sous vide needs no bags, machines or water baths.

3. Waring half-size convection oven: NSF listed
3 · Best for Commercial Kitchens
Verdict: For a restaurant needing half-size sheet pans; it is convection only, with no steam.
- 7 cubic feet Capacity
- 52.6 pounds Item Weight
- 1700 watts Wattage
- 23"D x 23"W x 15"H Dimensions
Best for Restaurant lines baking on half-size pans
Skip it if You need steam; take the SMEG.
What we like
- Half-size sheet pan capacity
- NSF certified per listing
- 1-year manufacturer warranty
What could be better
- No steam function
- Temperature range not stated
- 52.6 lb, heavier than the Cadco's 42 lb
Against the next pick: Beats the Cadco on pan size with a 23 inch width; loses on footprint, since the Cadco is 11.25 inches wide.
Not stated on the listing: temperature range.
No steam here. This is the commercial pick, not a combi. The listing says NSF certified and built for commercial kitchens and restaurants.
It takes a half-size sheet pan and comes with three racks and one pan. Four cooking functions: convection bake, roast, bake and broil. Knob controls and a tempered glass door.
At 1700 watts it draws less than the Crosson’s 3600. It is 23 inches wide and deep and weighs 52.6 pounds, so give it a firm counter.
The listing does not state a temperature range. Capacity is listed in cubic feet, 7, which does not fit a 23 inch cabinet, so treat that figure with caution and rely on the half-size pan spec.

4. Cadco quarter-size convection oven: tight spaces
4 · Smallest Footprint
Verdict: For kiosks and food trucks with almost no counter; it holds only quarter-size pans.
- 0.83 cubic feet Capacity
- 42 pounds Item Weight
- 1450 watts Wattage
- 14.13"D x 11.25"W x 9"H Dimensions
Best for Kiosks, food trucks and small bakeries
Skip it if You bake on half-size pans; choose the Waring.
What we like
- 11.25 in wide, 9 in tall
- 175-500°F range
- Commercial-style knobs and buzzer
What could be better
- 0.83 cu ft capacity
- No steam
- 42 lb is heavy for its size
Against the next pick: Beats the VEVOR on a 14.13 in depth against 48 in listed; loses on included accessories.
Not stated on the listing: temperature range.
Small is the point. It is 11.25 inches wide and 9 inches tall, the lowest of all eight listings on both counts.
The cost is volume. Capacity is 0.83 cubic feet, three shelf levels, quarter-size pans only. Cookies and pastries in small batches.
Knobs set 175-500°F, and an end-of-cycle buzzer sounds. The glass door is double-wall and cool-touch per the listing. At 1450 watts, it draws little.
It weighs 42 pounds despite its size, the same as the SMEG. No steam. The listing carries a one-year warranty, U.S. only.

5. VEVOR commercial convection oven: 19 quart
5 · Best Value Convection
Verdict: For a snack bar wanting a commercial-labelled oven with racks and gloves; the 1440W draw is the lowest listed.
- 19 quarts Capacity
- 32 pounds Item Weight
- 1440 watts Wattage
- 48"D x 48"W x 38"H Dimensions
Best for Snack bars needing small-batch baking
Skip it if You need steam; take the SMEG.
What we like
- Lowest wattage listed, 1440W
- 150-500°F with 0-120 min timer
- 3 racks, tray and gloves included
What could be better
- Dimensions inconsistent in the listing
- No steam
- Cavity sized for about three people
Against the next pick: Beats the Cadco on 19 quarts against 0.83 cubic feet in a different unit; loses on the 42 lb Cadco's tighter footprint.
Also sold as: 4-Tier 66L 2800W, 22-Tier 396L, 4-Tier 60Qt, 4-Tier 43Qt.
The listing is inconsistent. The specs give the unit size as 48 by 48 by 38 inches, but the text says 18.9 by 15 by 15 inches. The listing text gives the exterior as 18.9 by 15 by 15 inches, which conflicts with the 48 by 48 by 38 inch spec. Treat the dimensions as unreliable and measure before buying.
Inside, 19 quarts across 3 tiers, with a 14.2 by 13 by 8.7 inch cavity. Wattage is 1440, the lowest in the set.
Knobs control 150-500°F and a 0-120 minute timer. Three wire racks, a tray, bread clip and gloves are included.
Four-tier and other sizes are sold. No steam, and the listing says suited to a family of three, which undercuts the commercial label.

The buying guide
Checklist
- Real steam. A combi needs a water supply and steam modes, not just air fry.
- Pan size. Match quarter or half-size sheet pans to your trays.
- Footprint. Compare width and depth against your counter.
- Weight. Units here range from 20.9 to 71.9 pounds.
- Wattage. Check your circuit; listed draws run 1440 to 3600W.
- Certification. Only the Waring lists NSF.
Questions buyers ask
Which size should I pick?
Quarter size suits the Cadco at 11.25 inches wide. Half size needs the Waring’s 23 inches.
Do I need steam?
For bread and moist roasts, yes: take the SMEG. For baking only, no.
Is a commercial label enough?
Not alone. The VEVOR says commercial yet lists a family-of-three cavity.
Researched but cut
- Crosson double deck pizza oven Not what the search asks for A pizza oven, a different product type from a combi oven.
- CHEF iQ MiniOven Beaten on a listed spec A smart toaster oven air fryer; the listing states no steam or commercial rating.
- Midea Flexify French door oven Beaten on a listed spec Listed as an air fryer toaster oven with no steam or commercial rating; shelves not stated.
Our verdict on Commercial Combi Oven
Take the SMEG for real steam-convection on a counter, the Waring for rated half-size baking, the Cadco when space is the limit. None is a floor combi.
