For a single person or couple short on space, a 45 cm model is often the first option to consider when an under-counter appliance can be installed: the models mentioned offer 9 to 10 place settings, compared with 3 to 6 for compact countertop models. Choose a compact dishwasher when the available space genuinely cannot accommodate a 45 cm appliance, and always compare capacity, noise, water consumption per cycle, Eco programme duration and installation requirements before selecting a model.
A compact model may be suitable if the amount of washing-up is limited and you are happy to run cycles more frequently. French product listings from Whirlpool and Boulanger cited here indicate capacities of 3 to 6 place settings for compact appliances, while a 45 cm model may be more suitable when dishes build up between washes.
Compare the dB noise level and noise class shown on the energy label rather than assuming that a slim appliance will be quiet. Que Choisir highlights that noise is particularly important in an open-plan kitchen, while ADEME reminds consumers that the label also displays a noise class.
The choice between freestanding, built-in and semi-integrated models depends on the existing cabinet. Before choosing the installation type, confirm the housing-unit dimensions, any required door panel and the connections needed for the specific model.
Start by measuring the available space and the clearance in front of the appliance, then compare the capacity with how often you run washes. ADEME and the European Commission state that the energy label also allows you to compare water and energy consumption, Eco programme duration, capacity and noise.
| Priority | What to check | Your needs |
|---|---|---|
| Noise in an open-plan kitchen | Check the noise level in dB and the noise class on the label. Compare models of a similar format and check the conditions for any available quiet option. | I want to be able to start a cycle without the noise becoming too noticeable in the living area. |
| Capacity and footprint | Compare the number of place settings with the amount of washing-up produced between cycles. Measure the width, height, depth, door clearance and remaining passageway. | I want to avoid an appliance that is too small while keeping the kitchen easy to move around. |
| Water, energy and Eco duration | Compare kWh per 100 cycles, litres per cycle, Eco duration and capacity. Do not rely on the energy class alone. | I want to understand what each cycle means for my usual amount of washing-up and how often I plan to run the appliance. |
| Installation and integration | Check the water inlet, drainage and suitable electrical circuit. For a built-in model, also check the housing unit, door panel, plinth, fixing points and door opening. | I want to choose an appliance that is compatible with the available space and existing connections. |
A 45 cm appliance may still have a depth close to 60 cm. Without taking the height, door clearance and space in front of the appliance into account, it may obstruct movement.
Measure the width, height, depth, opening space and access route. For a built-in model, compare these measurements with the housing-unit plan for the exact model.
Size alone does not predict acoustic comfort: the compact models mentioned have different noise levels. In an open-plan room, this difference can matter every day.
Compare the noise level in dB and the noise class for each model, rather than comparing appliances solely by format.
The label distinguishes between energy, water, Eco programme duration, capacity and noise. Insufficient capacity may mean running the dishwasher more often, which the energy class alone cannot show.
Compare kWh per 100 cycles and litres per cycle with the number of place settings you actually need and how often you expect to run the appliance.
A built-in appliance must match the cabinetry and be secured according to its design. A connected dishwasher also requires a suitable water inlet, drainage connection and electrical supply.
Check the technical plan, housing unit, any required door panel, water connections and drainage before buying. Promotelec states that a dishwasher socket must be on a dedicated circuit and located close to the required water connections and drainage.
The Bosch range includes 45 cm freestanding and fully integrated dishwashers, making it useful for comparing dimensions, noise levels and Eco programme data in a small kitchen.
Whirlpool offers 45 cm freestanding, semi-integrated and built-in appliances, allowing you to compare several installation types when space is limited.
This range provides a useful benchmark when comparing a 45 cm freestanding model and when noise, capacity and Eco programme data are key considerations.
Siemens offers 45 cm models and compact freestanding or integrated appliances to consider when the available width or cabinetry limits your options.
This selection brings together compact countertop dishwashers for a small household or very limited space. It helps you compare capacity, stated water-supply options and available noise data before confirming the available space and installation requirements.

For a small household looking for a countertop format with a stated capacity of 6 place settings.
7 programmes, stated noise level of 47 dB, 6.5 L per cycle, 49 kWh/100 uses and a 215-minute Eco programme. Check the external dimensions, door opening, noise class and connection compatibility for your home.

For very limited use, with a stated 5 L tank or direct connection to the tap.
Stated capacity of 3 place settings, 7 programmes, 56.3 dB, 4.2 L per wash and a 205-minute Eco programme. Confirm the footprint, drainage instructions and noise class before buying.

For a very restricted worktop, with stated dimensions of 420 × 436 × 465 mm and a tank that must be filled manually.
Stated capacity of 3 place settings, 7 programmes, delay start and automatic door opening. Check the noise level, consumption figures, Eco duration, drainage and the clear space around the appliance.
No. It is mainly suitable when a 45 cm under-counter appliance cannot be installed and the amount of washing-up is small. The compact models mentioned offer 3 to 6 place settings, while 45 cm Whirlpool and Miele models list 9 or 10 place settings: if dishes build up, a 45 cm model may reduce the need to run frequent cycles.
Compare the noise level in dB and the noise class on the energy label for the exact model. ADEME states that the label shows a noise class from A to D and notes that classes A or B are particularly quiet; Que Choisir highlights that noise is an important consideration when the kitchen is open-plan.
Confirm that the water inlet, drainage and suitable electrical supply are accessible for the model. Promotelec states that a dishwasher socket must be on a dedicated circuit and located close to the required water connections and drainage; for a built-in model, also check the housing unit, fixing points and any required door panel.
No. It allows you to compare the energy class, kWh per 100 cycles, litres per cycle, capacity, Eco programme duration and noise, but the actual dimensions, installation and basket layout also need to be considered. The European Commission specifies that these figures are displayed for the Eco programme.
