If you have a suitable space, a 45 cm dishwasher is worth considering first. Its capacity may suit a small household, although you might need to run it every day. If you have no floor space to spare, a compact countertop or mini dishwasher takes up less room on the floor, but holds fewer dishes per load and may have installation or connection requirements to check. In an open-plan kitchen, also consider the noise level and Eco cycle duration alongside the times you plan to use it.
Which size is right for you?
Small household with space for a 45 cm model
If the connections are within reach, compare 9- to 10-place-setting models with the amount of washing-up you generate each day. Que Choisir says a 9-place-setting model may suit a small family, although it might need to run daily.
Studio resident with no floor space to spare
A countertop appliance leaves your lower cabinets and walkways clear, but takes up worktop space. Before choosing this size, check its capacity, how much room it needs with the door open, and its water supply and drainage requirements.
Household sensitive to noise in the living area
If the dishwasher will run during mealtimes, while you work or in the evening, compare the dB rating and noise class shown on the energy label. ADEME lists both as factors to consider when choosing.
What sets the different sizes apart?
In a small open-plan kitchen, first check where the appliance can sit or be built in, then consider whether its capacity and noise level suit your lifestyle.
| Factor | What to check | Who it matters to |
| Space required |
Measure the width, depth and height, and allow enough room to open the door. A countertop model frees up floor space but takes up worktop space. |
When every centimetre counts, I want to keep the walkway clear and have enough worktop space to cook. Around 36% of consumers would put the appliance’s position at the top of their list of needs. |
| Capacity and cycles |
Compare the number of place settings with a typical day’s washing-up, including larger items. Que Choisir warns that a 9-place-setting, 45 cm model may need to run every day. |
If I cook regularly, I don’t want to run extra cycles just to get through the washing-up. Capacity would be the top priority for around 29% of consumers. |
| Noise |
Compare the dB rating and noise class on the label, then check how long the Eco cycle takes if you plan to run it while the living area is in use. |
If I’m working or relaxing near the kitchen, I need a cycle with a noise level I can live with. This would be the top concern for around 21% of consumers. |
| Installation |
Check the manual for the water inlet, drainage, plug socket and clearance requirements, as well as the cabinet space and door panel if needed. Don’t assume a “mini” model works without a water connection. |
With a fitted kitchen, I need to know whether the appliance can be installed in the space available. Around 14% of consumers would make this their main requirement. |
Mistakes to avoid before ordering
-
Looking only at the “45 cm” width
A slim appliance can still be deep or obstruct the walkway when its door is open. An integrated model must also fit the cabinet space and door panel you have planned.
Check the overall dimensions, door clearance and installation instructions for the exact model.
-
Assuming “compact” means “no plumbing needed”
Some countertop appliances need a direct water connection, while a model with a tank still needs a suitable drainage solution.
Before choosing where to put it, check the manual for the water supply, drainage, plug socket and installation requirements.
-
Taking “quiet” as a measurement
In an open-plan kitchen, the name of a programme alone doesn’t tell you how noisy every cycle will be. According to ADEME, a 3 dB increase almost doubles the noise level.
Compare the dB rating, noise class and duration of the programmes you plan to use.
-
Choosing a capacity without considering larger items
A small appliance may fit your everyday dishes, but you could need extra cycles for pans or after a bigger meal.
Make a list of the items you wash on a typical day and check how the racks are arranged, rather than looking only at the stated number of place settings.

Frequently asked questions
What should I measure before choosing a 45 cm or countertop model?
Measure the width, depth and height, and allow enough space in front for the door to open. Then compare these measurements with the appliance’s overall dimensions and the clearances specified in the manual. A “45 cm” width or “compact” label alone doesn’t confirm that it will fit.
Is a 45 cm dishwasher big enough for a small household?
It may be, if the racks fit your usual dishes and you’re happy with how often you’ll need to run it. Que Choisir says a 9-place-setting model may suit a small family, although it might need to run every day. Also check how much room there is for pans and other larger items.
How can I compare noise levels in an open-plan kitchen?
Compare the dB rating and noise class on the label, then check how long the cycles you plan to use take when the living area is occupied. According to ADEME, an extra 3 dB almost doubles the noise level. A programme called “Silence” is no substitute for these figures.
Does a mini dishwasher always work without a water connection?
No: the water supply option depends on the model. For example, Candy describes the CP 6E51LS as having a direct water connection, while other appliances have a tank. Check the manual to confirm the water supply, drainage, plug socket and installation requirements for the model you choose.
