A kitchen with one available space
You want to combine oven cooking and reheating without setting aside a separate space for a microwave. It’s still essential to check that the appliance is compatible with your cabinet.
Who is this choice for?
Fans of cooking large dishes
You mainly use the oven and want to compare the usable cavity space and shelf positions available for your cooking.
Replacing a built-in appliance
You already have a housing and need to check its dimensions and the installation instructions for the exact model before ordering.
What should you compare before choosing?
Built-in convection oven
Choose this if: oven cooking is your priority and you don’t expect to use the appliance for microwave reheating.
Keep in mind: this option doesn’t include a microwave function. Check the dimensions and instructions for the model you choose.
Convection microwave combination oven
Choose this if: you want to cook, reheat and defrost in a single built-in appliance, and its cavity is large enough for your dishes.
Keep in mind: a single cavity means you can’t use two appliances separately at the same time, and a compact model won’t necessarily fit a taller housing.
| What matters | What to check | Who it matters most to |
|---|---|---|
| Compatibility with the housing | Measure the housing and check its dimensions, ventilation requirements and connection instructions against the manual for the exact model. | If I’m replacing an appliance, I want to know that the model will fit my cabinet before I order. Around 26% of consumers prioritise built-in compatibility. |
| Combining cooking and reheating | Check that the model includes both convection and microwave functions, and see which modes can be used together. | If I only have one available space, I want to cook and reheat without installing two separate appliances. Around 26% of consumers prioritise combining these functions. |
| Room for your dishes | Compare the usable cavity dimensions, accessories and shelf positions with the dishes you use. | When I’m cooking large dishes, I want to check they’ll fit and plan how to cook them in batches. Around 21% of consumers put capacity for their dishes at the top of their list. |
| Energy use by mode | Only compare energy use for equivalent cycles and modes; don’t infer microwave energy use from the oven’s figures. | If energy use is a factor in my decision, I want to compare figures that reflect the cooking modes I actually use. Around 16% of consumers prioritise a meaningful energy comparison. |
| Cleaning and aftercare | Read the model’s cleaning instructions and check who the seller is and which warranties apply. | If I want to plan ahead for cleaning and aftercare, I check the instructions and support terms. Around 11% of consumers make these their main priority. |
Pitfalls to avoid
-
Confusing external dimensions with built-in compatibility
A compact combination oven and a conventional oven can have different external heights, so the front of the appliance alone won’t confirm whether it will fit the housing.
Before ordering, compare the dimensions of the housing with the installation requirements for the exact model. Don’t assume an appliance will be a direct replacement for your old one.
You may need to adapt the cabinet or installation.
-
Choosing a combination oven assuming it will always use less energy
The technical study by the National Consumer Institute and ADEME covers built-in models tested with three recipes; its findings can’t be applied to every appliance and way of using it.
Start by choosing a model that suits your cooking habits, dishes and housing. To compare energy use, check the test method and conditions behind the results.

Confusing a microwave with grill with a convection combination oven
If you want to replace oven cooking, check that the model actually has a convection mode, rather than just a grill function alongside the microwave.
Check the full model’s list of cooking modes in its product details and manual.
Brands and models to know
Bosch
The models featured by Bosch Home Appliances France illustrate both formats: the HBA534BS3 is a 60 × 60 cm convection oven, while the CMG7241B1 is a compact combination oven listed in a 60 × 45 cm format.
- Bosch lists three hot-air cooking levels for the HBA534BS3 and a 45 L cavity for the CMG7241B1.
- These specifications apply to these models and don’t provide an independent comparison of their cooking performance. Check the installation manual for the exact model.
Samsung
Samsung France describes the NQ5B6753CAK/U1 as a built-in model combining microwave and oven cooking.
- Samsung lists a 50 L capacity for this model.
- The features highlighted by the brand don’t guarantee that the cavity or cooking modes will suit every dish. Check the installation dimensions too.
Beko
The BBIE17300BMP is a built-in convection oven model featured by Beko France.
- Beko lists an A energy rating and pyrolytic cleaning for this model.
- These details don’t show that it will use less energy than a combination oven, nor can they be assumed to apply to every Beko model.

Frequently asked questions
Is a 60 cm front enough to check whether an oven will fit in my kitchen?
No. The width of the front alone isn’t enough to confirm compatibility. Bosch Home Appliances France lists external heights of 455 mm for the CMG7241B1 and 595 mm for the HBA534BS3. Compare the dimensions of your housing and the installation instructions for the exact model.
How do you clean a combination oven?
Follow the instructions for the model and the mode you’re using. Bosch lists hydrolysis-assisted cleaning for the CMG7241B1, but cleaning methods vary between models.
Who is responsible if goods don’t conform after a purchase from a professional seller in France?
The legal guarantee of conformity applies to purchases of goods by consumers from professional sellers and is separate from a commercial warranty. The French Ministry of the Economy and Finance confirms that it is mandatory; the details depend on the circumstances of the purchase and the fault.
What should I do with my old oven when replacing it?
The French Ministry for the Ecological Transition describes a ‘one-for-one’ take-back scheme when you buy equipment of the same type. Ask the seller how take-back arrangements apply to your order and delivery.
Can the energy label be used to compare a combination oven’s microwave mode directly with a conventional oven?
No. The European Commission explains that ovens with a microwave heating function fall outside the scope described for domestic ovens, whose energy use is stated per cycle for conventional or fan-assisted modes. Don’t use this information to infer comparative energy use in microwave mode.
