Start by measuring the actual space available and planning the water route. A mini dishwasher with a tank can avoid the need for a fixed water supply, but wastewater still needs somewhere to go and capacity is limited. If you already have floor space and compatible connections, a 45 cm model offers more room without requiring the 60 cm width of a standard appliance.
A mini model with a tank could be suitable if you have a stable worktop and a way to drain the water. Daan Tech describes this type of use for its Bob model; UFC-Que Choisir also mentions this format for single people or couples without room for a conventional appliance.
If washing-up builds up over several meals, first measure the space available for a 45 cm model. Bosch, Beko and Miele offer slimline formats with a stated capacity greater than that of a mini countertop appliance.
A slimline or standard appliance could be considered when the full dimensions, water supply and drainage already match the property. Check the instructions for your chosen model before installation.
Consider it when: a worktop can accommodate the appliance but no fixed water supply is easy to use.
Trade-off: the tank reduces the need for a water-supply connection on models designed for this, but it does not remove the need for drainage or overcome the limited capacity.
Consider it when: you have floor space, a water supply and accessible drainage.
Trade-off: you need to allow for depth, door opening and hose routing, not just a width of 45 cm.
Consider it when: your kitchen already has the necessary space and connections, and capacity is the priority.
Trade-off: its dimensions do not solve the problem of having no dedicated space in a small kitchen.
| Priority | What to check | Your needs |
|---|---|---|
| Space and connections | Measure the height, width and depth. Check the water-supply method and the route of the drain hose according to the instructions. | I want an appliance that genuinely fits in the available space and can drain water properly, even if I do not have a fixed water supply. |
| Capacity and crockery | Compare the stated number of place settings, the maximum plate size and the basket layout. Take your frying pans and large dishes into account. | My plates, glasses and utensils need to fit between washes without forcing me to run cycles too frequently. |
| Running costs | Compare Eco programme data between appliances of a similar size. Add detergent, rinse aid, salt where required and maintenance costs. | I want to anticipate ongoing costs, not just the purchase price. UFC-Que Choisir recommends including consumables and maintenance in the overall budget. |
The tank can replace a fixed water supply on some appliances, but wastewater must still leave through a hose. Daan Tech makes this clear for its Bob mini dishwasher.
Before buying, work out where the drain hose will be positioned or connected, and check the lengths and conditions specified in the instructions.
The 45 cm and 60 cm Bosch examples are also 60 cm deep. You must also allow the clearance needed to open the door and route the hoses.
Measure the height, width, depth, doorway access and opening space, then compare them with the exact model’s overall dimensions.
Capacity is the main compromise. Daan Tech states that Bob holds up to two place settings according to the European standard, while a 45 cm slimline model may state a higher number depending on the reference.
Measure your largest plates and list the crockery produced between washes. If this regularly exceeds the capacity of a mini model, consider a 45 cm appliance.
Your budget also depends on water, energy, cleaning products and maintenance. UFC-Que Choisir recommends taking these costs into account.
Compare labels and Eco programme data for comparable appliances, then add the consumables required to your annual estimate.
In particular, allow for detergent, rinse aid, dishwasher salt where required and routine maintenance.
French brand offering Bob, a highly compact countertop mini dishwasher that can be used with an integrated tank or connected to a water supply, depending on the setup.

Yes, if the model has a tank designed for manual filling. Daan Tech states that Bob has an integrated 3,9 L tank and can also be connected to a conventional water supply, depending on the setup. Check this operating method in the instructions for the exact model.
Yes. An appliance that is self-contained for its water supply must still drain wastewater. For Bob, Daan Tech states that the hose can be placed in the sink, connected to a trap or attached to suitable drainage.
