Combination Wall Oven Buying Guide
Combination wall ovens pair a traditional oven (usually a single wall oven) with a secondary cooking appliance above it - often a microwave, speed oven, or steam oven. This combo saves space while providing more cooking versatility. Popular in modern kitchens, they combine convenience with high-end performance, especially for households that want multi-functionality without a double oven footprint.
1. What is a Combination Wall Oven?
Key Advantages
Pros:
Two-in-one design – saves space by combining an oven with a microwave or steam oven.
Streamlined kitchen layout – eliminates the need for a separate countertop microwave.
Variety of secondary options – microwave, convection microwave, speed oven, or steam oven.
Modern, built-in look – blends seamlessly into cabinetry.
Flexible cooking – bake, roast, reheat, and defrost in one unit.
Ergonomic installation – place at eye or waist level for easy access.
Good for smaller kitchens – maximizes function without extra appliances.
Cons:
More expensive than single ovens – higher upfront cost.
Secondary oven smaller – limited space for large dishes in the top unit.
Less cooking capacity than double ovens – better for everyday, not large feasts.
Repairs can be costly – multiple appliances built into one unit.
Replacement limitations – requires same-sized combo unit if one fails.
Limited gas options – almost exclusively electric.
Cabinetry cutout required – professional installation needed.
Configuration and Cooking Features
Main oven – typically 27" or 30", 4.0–5.1 cu. ft. capacity.
Upper unit options:
Standard microwave.
Convection microwave (bakes/roasts small dishes).
Speed oven (combines microwave + convection + broiler).
Steam oven (healthy cooking option)
Cooking modes – bake, roast, convection, broil, defrost, reheat.
Multiple rack positions – maximize flexibility in lower oven.
Self-cleaning options – high-heat or steam for lower oven.
Touchscreen, knob, or hybrid controls – varies by model.
Split functionality – operate upper and lower units independently.
Performance Features
Convection fans – for even baking and roasting in the lower oven.
Convection microwaves/speed ovens – cook faster and more evenly than standard microwaves.
Rapid preheat – reduces wait time in the main oven.
Temperature probes – monitor roasts or poultry precisely.
Keep warm settings – maintain food temp in either oven.
Timed cooking – operate both units separately with schedules.
Special modes – proof dough, dehydrate, or air fry (select models).
Quiet fans and cooling systems – minimize noise during extended use.
Energy Efficiency
Electric-only models – ensure consistent performance.
Convection in microwave/steam ovens – reduces cook times, saving energy.
Smaller top oven cavity – efficient for reheating or small meals.
Steam clean options – energy-friendly compared to high-heat clean.
LED lighting – reduces energy use while improving visibility.
Use flexibility – small meals in the upper oven avoid heating a large cavity.
Good insulation – prevents kitchen heat loss.
Residual heat use – keep food warm without additional energy draw.
Smart Features (Optional)
Wi-Fi connectivity – control and monitor both ovens remotely.
App integration – set modes, timers, and get notifications.
Voice assistant support – Alexa, Google, Siri integration.
Recipe-guided cooking – adjusts cook times and modes automatically.
Push alerts – notifications when food is done or reheating finishes.
Smart diagnostics – app-based troubleshooting.
Automatic updates – new cooking features via firmware upgrades.
Sync with other smart appliances – like cooktops or fridges.
2. Sizing and Installation Requirements
Before making your decision, make sure it fits in your kitchen setup.
Widths: Standard 27" or 30".
Heights: ~42–44 inches (varies with upper oven type).
Depth: ~23–25 inches, requires cabinet cutout.
Capacity: Lower oven 4.0–5.1 cu. ft.; upper oven 1.0–2.0 cu. ft. (depending on type).
Fuel: Electric only (240-volt, 30–40 amps).
Cabinetry requirements: Tall cabinet with reinforced support.
Ventilation space: Required for both top and bottom units.
Professional installation recommended – weight and wiring complexity.
3. Maintenance Tips
Clean spills promptly – especially in the microwave/steam oven section.
Use correct cleaners – avoid abrasives on glass, enamel, or stainless finishes.
Check microwave/steam oven seals – ensure proper heating efficiency.
Run self-clean cycles sparingly – avoid excess wear on lower oven.
Remove racks before high-heat cleaning – prevents discoloration.
Check for vent blockages – especially around upper oven.
Regular descaling (steam ovens) – prevents mineral buildup.
Schedule professional service – important for multi-appliance units.
4. Price Range
Entry-level ($2,000–$3,000) – microwave + oven combo, simple features.
Mid-range ($3,000–$4,500) – convection microwave or steam oven on top, convection lower oven.
Upper mid-range ($4,500–$6,000) – speed oven combos, larger capacity, better finishes.
High-end ($6,000–$8,000) – advanced smart features, steam/convection, premium styling.
Luxury/professional ($8,000–$12,000+) – chef-grade combos, oversized capacities, fully integrated smart ecosystems.
