Small-worktop sauce reheaters
If you usually warm one bowl of sauce or leftovers, measure the space a microwave can occupy before choosing by litre capacity. Allow for the exact model’s ventilation and door-opening requirements.
Who this choice suits
Cooks concerned about uneven heating
For thick sauce, choose a bowl that can rotate freely and a microwave you can pause to stir. The Food Standards Agency advises including stirring and standing in the microwave reheating process.
Kitchen planners considering a built-in model
If keeping the worktop clear matters more than a straightforward countertop installation, check cabinet dimensions, ventilation and installation requirements before choosing a built-in microwave.
What matters when buying
Decide whether the microwave must sit on the worktop or can be built into cabinetry. Then check the space it needs, the bowl you use and the controls you prefer.
17-litre countertop solo
Choose when: One bowl at a time is typical and preserving worktop area is the priority.
Trade-off: The Cookworks and Russell Hobbs examples have 24.5 cm turntables, leaving less room for dishes than the 20-litre Russell Hobbs Distinctions example.
20-litre compact solo
Choose when: A slightly larger appliance fits and you want the 25.5 cm turntable and automatic programmes of the Russell Hobbs Distinctions RHMD832T.
Trade-off: At W45.6 × D32.6 cm, that model occupies more worktop width than the two 17-litre countertop examples.
Built-in solo
Choose when: Suitable cabinetry can accommodate an appliance without using the worktop.
Trade-off: The Montpellier MWBI17-300 needs an appropriate cabinet and ventilation arrangement; The installation documentation specifies professional installation.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop fit | Measure usable width, depth and height; check the exact model’s ventilation clearance and door swing. | If I have barely enough counter room for a microwave, I need to know it can be placed and opened properly. Around 42% of consumers would put worktop fit first. |
| Sauce reheating | Check that your microwave-safe bowl rotates freely and that you can pause to stir. Follow standing instructions and check for heat throughout; the Food Standards Agency includes stirring and standing in microwave reheating advice. | When I warm thick mushroom sauce, I do not want a hot edge and a cool centre. Reheating it throughout would be the primary concern for around 33% of consumers. |
| Controls and bowl size | Compare the controls and turntable diameter with the bowl or plate you normally use. | For a quick daily serving, I want settings I can use easily and enough room for my usual bowl. Around 25% of consumers would prioritise that combination. |
Buying pitfalls
-
Choosing by litre capacity alone
Two 17-litre countertop microwaves can have different external dimensions, while a 17-litre built-in model has different installation requirements altogether.
Measure the available location, then check the exact model’s manual for clearance, cable placement and room for the door to open.
-
Assuming more watts mean evenly heated sauce
An 800 W rating does not remove the need to stir thick sauce and check it throughout. The Food Standards Agency includes stirring and standing in microwave reheating guidance.
Use a microwave-safe bowl that rotates freely, pause to stir, follow any standing instructions and check that the sauce is steaming hot throughout before serving.
-
Heating sauce in a sealed container or using a damaged microwave
The instruction manual for the cited model P70J17AP-VB warns that sealed containers can explode and that a damaged appliance must not be operated.
Do not reheat sauce in a sealed container. If the microwave door or seal is damaged, stop using the appliance until a competent person has repaired it.

Common questions
Is a 17-litre microwave enough for one bowl of mushroom sauce?
A 17-litre countertop solo model is a sensible starting point for one bowl, provided the bowl sits securely and rotates freely. The product information lists the Cookworks 17 L model at H24.3 × W44.6 × D32.3 cm and the Russell Hobbs RHMM701B at H25.6 × W45.1 × D32.6 cm; check the exact model’s clearances as well as those dimensions.
How do I reheat mushroom sauce throughout?
Stir it during reheating, follow any pack and standing instructions, then check that it is steaming hot throughout. The Food Standards Agency includes standing and stirring in its microwave reheating guidance; elapsed time or wattage alone does not tell you whether the whole serving is hot.
Can I put a countertop microwave inside a cupboard?
Do not assume a countertop model can be enclosed: follow its exact ventilation and placement instructions. If you need an appliance installed in cabinetry, check a purpose-built built-in model’s cabinet and electrical requirements; The installation documentation specifies professional installation for the Montpellier MWBI17-300.
What electrical supply should I check before buying?
Check the rating and plug requirements of the exact microwave you choose. The instruction manual for the cited model P70J17AP-VB specifies a 230–240 V AC, 50 Hz supply; do not apply that model-specific specification to every microwave.
