Start by measuring the width, depth, height and clearance required: a top-loading washing machine is best suited to a lack of width, while a slim front-loader mainly reduces depth. A standard front-loader works when the recess can accommodate around 60 cm in width and there is enough room to access the door; then compare capacity, spin-cycle noise, the energy label and installation compatibility.
You have a shallow recess, but around 60 cm of width and access in front of the door are still possible: a slim front-loader can reduce the depth to around 33 to 45 cm, although capacity is often limited to 4 to 6 kg. UFC-Que Choisir cites these dimensions for slim models.
You are mainly short of width or cannot leave enough space in front of the appliance: a top-loader measuring 40 to 46 cm wide is worth considering, provided you can open its lid from above. UFC-Que Choisir gives this range for top-loading washing machines.
You want to keep an appliance suited to your everyday laundry: compare the capacity with the actual volume of washing before opting for a compact or mini appliance. ADEME states that a 7 kg washing machine is sufficient most of the time and recommends avoiding multiple cycles with an unsuitable drum size.
Start with the dimension that genuinely limits installation, then check the capacity and the model’s suitability for everyday use.
| Priority | What to check | Your needs |
|---|---|---|
| Compatible dimensions | Measure the overall width, depth and height. Also check the opening space needed for the front door or top lid. Under-counter installation must be approved for the model. | I need to know whether the lack of space mainly concerns the width, depth, clearance beneath a worktop or the room around the appliance. |
| Suitable capacity | Compare the stated kg capacity with your usual loads, including bed linen and towels. The slim models cited by UFC-Que Choisir commonly offer 4 to 6 kg; mini models are intended for small loads. | I want to keep a drum size that suits my everyday laundry rather than automatically choosing the smallest format. |
| Ease of use | Compare the noise level and spin-noise class on the energy label. Check the manual for access to the filter and the required maintenance procedures. | If the machine is near a living area, I want to minimise noise disruption and be able to maintain it easily. UFC-Que Choisir reports that spin-cycle noise, washing time and maintenance received more mixed feedback from respondents to its newsletter. |
| Energy use and durability | Use the energy label to compare the class, kWh per 100 cycles, litres per cycle and spin performance. In France, also check the model’s durability index. | Once I have confirmed that the appliance will fit, I want to compare compatible machines based on their stated consumption and whether they can be repaired. |
A top-loader is generally narrow, but it may still be 60 cm deep. A slim model usually remains close to 60 cm wide while reducing the depth, so choosing the wrong format may leave it incompatible with the recess.
Map out the space in three dimensions and first choose between a top-loader, standard front-loader and slim model according to the measurement that is genuinely restrictive.
A drum that is too small may mean running more cycles. UFC-Que Choisir presents 2 to 3 kg mini washing machines as an additional appliance, while ADEME states that 7 kg is sufficient most of the time.
Compare the rated capacity with your usual loads, including bed linen and towels, before choosing a compact or mini washing machine.
Additional cycles can increase water and electricity use when the drum is too small for your usual loads.
An incompatible stacked installation may be unstable. Bosch specifies that its WTZ27510 kit is intended for full-size washing machines more than 55 cm deep and requires a compatibility check.
Check the exact references of both appliances, the minimum depth, the specified kit and the manufacturer’s instructions before buying.
UFC-Que Choisir presents 2 to 3 kg mini models as additional appliances. Their limited capacity makes it difficult to wash bulky items and may result in more cycles.
Choose this format only when no compatible top-loader, slim or front-loader can be installed, and check the types and volumes of laundry you will actually need to wash.
Electrolux provides a useful benchmark when comparing a 6 kg slim front-loader where depth is restricted: the EW6S1064NA is listed with a depth of 411 mm.
Whirlpool offers a useful comparison for a narrow top-loading format: the TDLR6253BFR measures 40 cm wide, 90 cm high and 60 cm deep, with a 6 kg capacity.
Bosch is worth considering when comparing standard front-loaders and under-counter or stacked installations, provided the exact references are compatible.
In France, Candy offers a collection of slim washing machines and appliances with a range of capacities, including freestanding models from 7 to 9 kg and a 5 kg Mini ProWash.
These Joybuy options include a narrow top-loader, a high-capacity standard front-loader and a front-loader presented as slim. Compare them with the measurements of your space before choosing.

Worth considering for a space mainly limited by width, provided the top of the appliance remains accessible.
Stated width of 40.5 cm, 6 kg capacity, 1,400 rpm, 49 kWh/100 cycles and 41 L/cycle.
Its stated depth of 60 cm will not solve a lack of depth. Check the vertical clearance needed for the lid; the stated spin noise is 79 dB(A), class C.

This option is better suited to a household that wants to keep a large drum and has sufficient space in front of the appliance.
Stated capacity of 9 kg, dimensions of 84.7 × 59.7 × 66.0 cm, A energy class, 44 kWh/100 cycles, 48 L/cycle and 72 dB during spinning, class A.
The stated depth of 66.0 cm must fit the recess, with enough clearance for the door. Check the manual before considering under-counter installation or stacking.

This model may suit a household looking for a large capacity in a compact front-loader, once all dimensions have been checked carefully.
Stated capacity of 9 kg, 530 mm drum, 1,400 rpm spin speed, 16 cycles and a 15-minute quick programme.
The stated depth measurements are contradictory: 57.7 cm in one place and 465 mm in another. Check the technical specifications or manual, along with the spin noise and any under-counter or stacking compatibility.
Measure the overall width, depth and height of the space, then check the access route needed for delivery. Allow for opening clearance too: in front for a door and above for a top-loader. A top-loader mainly saves width, while a slim model mainly reduces depth.
No, not automatically. UFC-Que Choisir states that slim models generally offer around 4 to 6 kg; a 6 kg model may suit regular small loads, but compare its capacity with the laundry you actually wash. ADEME states that a 7 kg washing machine is sufficient most of the time.
No. Check the model’s manual and specifications: Bosch distinguishes, in particular, under-counter washing machines with a removable top, for which an under-counter cover may be required. A standard freestanding appliance should not be assumed to be suitable for under-counter installation based on its height alone.
Do not assume so. Stacking requires a kit compatible with the specific references involved. For example, Bosch specifies that the WTZ27510 kit is designed for a full-size washing machine with a depth of more than 55 cm; this condition probably rules out many slim models.
Compare the energy class, kWh per 100 cycles, litres per cycle, spin efficiency and noise level. ADEME states that washing machine energy labels provide this information and recommends a spin class A when laundry needs to dry quickly indoors or in a tumble dryer.
