A mini dishwasher with a built-in water tank can be suitable without a fixed water supply, but you will still need to plan where its drain hose goes. A plumbed-in compact model is better suited when the water inlet and drainage are already accessible, while a 45 cm freestanding dishwasher is more suitable for regular heavy use, at the cost of taking up similar space and requiring connections comparable to those of a standard dishwasher.
Your main aim is to avoid a fixed water supply and you are happy to fill a tank, but you still need to plan for wastewater drainage and a suitable power supply. Daan Tech sets out these requirements for its Bob model.
A plumbed-in countertop compact model may be worth considering if the existing connections are accessible and compatible. A freestanding appliance also requires a water inlet, drainage and a socket, as Whirlpool France points out.
If a mini dishwasher means running too many cycles, a 45 cm freestanding model may offer more capacity. However, the Whirlpool and Bosch examples reviewed require floor space and connections comparable to those of a standard appliance.
Consider it: if no fixed water supply is accessible and your load remains limited.
Plan for: the tank removes the need for a fixed water supply, but not the need to route and secure the drain hose.
Consider it: if the worktop, water supply, drainage and a socket are already accessible.
Plan for: saving space does not remove the need for connections, and a 6-place-setting capacity may mean running frequent cycles.
Consider it: if the connections are already in place and your daily washing-up exceeds the capacity of a compact model.
Plan for: a stable location, considerable height and performance that varies depending on the exact model.
| Priority | What to check | Your needs |
|---|---|---|
| Connections and drainage | Check how the appliance is supplied with water, the route taken by the drain hose and where it will be secured. A tank does not remove the need to drain wastewater. | I want to minimise fixed connections, but I can fill a tank and arrange safe drainage. |
| Actual capacity | Compare the number of place settings with your plates, glasses, saucepans and frying pans. Also measure the width, depth, height and door opening. | I am looking for an appliance large enough for my washing-up routine, without unnecessarily taking over the worktop or floor space. |
| Water, energy and noise | Compare litres per cycle, kWh per 100 cycles, the noise level and its class on the exact model’s label. ADEME explains that an extra three decibels represents an almost doubling of the noise. | In a studio flat or open-plan kitchen, I want to compare noise and consumption rather than looking only at the appliance’s format. |
| Safe positioning | Check that the support or floor is stable, that the socket is accessible, that the connections are watertight and that the hoses have sufficient clearance. Follow the instructions for the model you choose. | I want to install the appliance where the existing connections and available space are genuinely suitable. |
A tank only removes the need for a fixed water supply. Daan Tech states that the drain hose must still be connected and secured; the discharged water may be hot, depending on the model.
Before buying, identify the hose route, the trap or drainage solution specified in the instructions, and how to secure the hose without risking leaks.
A countertop appliance can still be deep, while a 45 cm freestanding model generally requires more height and depth. The format tells you neither the actual capacity nor the connections required.
Measure the width, depth, height, door opening and hose clearance, then compare the capacity with your usual washing-up load.
The two 45 cm Bosch models reviewed show different figures: 8.9 L per cycle and noise class C for the SPS2HKI58E, compared with 8.7 L per cycle and noise class B for the SPS4EMI17E.
Compare the label for the exact model, especially litres per cycle, kWh per 100 cycles and noise, rather than relying on the width or brand.
Installation services may connect an appliance to a compliant existing installation, but they do not carry out the plumbing, electrical or joinery work required when the connections are missing.
Check what is available beneath the sink and near the chosen location. If alterations are needed, have them assessed separately before placing your order.

For a small kitchen without a fixed water supply, with manual filling of the 5 L tank or the option to connect it to the tap.
Listed format: 420 × 435 × 435 mm; designed for 2 to 3 people. The drain hose must be secured correctly and the tap adaptor is not included.
Image unavailable
An option for a very small load, with a 5 L tank to fill manually or a direct connection to the tap.
3 place settings, 7 programmes, water softener and a listed noise level of approximately 56 dB. Wastewater drainage still needs to be arranged.
Image unavailable
Worth considering if an existing water supply is accessible and a capacity of 6 place settings suits your household.
7 programmes, a listed noise level of 47 dB, 49 kWh per 100 uses and 6.5 L per cycle. Check the 3/4-inch connection, drain route and the actual amount of worktop space available.
Image unavailable
For a larger worktop load, without a permanent water supply thanks to its integrated 5 L tank.
Two levels, three spray arms and five listed cycles; the upper basket can be removed to accommodate plates up to 300 mm. Check the drainage, dimensions and any tap adaptor required.

For a small home with an accessible tap and a very small washing-up load.
Listed capacity of 3 place settings; the description specifies a connection to the tap and placing the drain hose in a sink or bucket. Check the connection, hose lengths and how to secure the drainage safely.
It can operate without a fixed water supply if its tank is filled manually, but wastewater must still be drained. For Bob, Daan Tech documents a built-in 4 L tank and requires the drain hose to be connected and locked in place.
It generally takes up less space, but it does not eliminate the need for connections. The Candy CP 6E51LS is listed with a direct connection to the water supply, while a freestanding model also requires a water inlet, drainage and a socket: the available space and expected capacity remain decisive.
Compare the energy class, kWh per 100 cycles, litres per cycle, capacity, Eco programme duration and noise level together with its class. ADEME states that this information appears on the label and that an extra three decibels represents an almost doubling of the noise.
Yes, when cycle duration is not a priority and the machine can be filled appropriately. A document from the Ministries for Ecological Transition and Energy and ADEME states that it can save up to 45% electricity compared with an intensive programme; also check the stated figures for the exact model.
Do not assume that delivery or installation includes building work. Electrolux France specifies that connections are made to compliant installations and that installers do not carry out joinery, plumbing or electrical work; check the instructions, existing connections and location before ordering.
