Start by choosing a format based on the dimension that’s actually restricting the installation: a top-loading washing machine is best suited to a lack of width, while a slim or compact front-loader may work when depth is limited. If you’re planning a washer-dryer stack, compatibility between the washing machine, tumble dryer and stacking kit matters more than a shallow depth alone. In every case, check the door clearance, connections and capacity of the model you choose.
If you’re fitting a machine into an alcove or narrow space, start by measuring how much width you have available. Que Choisir describes top-loading washing machines as generally narrower than front-loaders, although you’ll need enough clearance above the machine to open the lid.
If a front-loader would fit widthways but its depth would obstruct the walkway, compare slim or compact models. Remember to allow space to open the door and access the connections, too.
If you’re planning to put a tumble dryer on top of your washing machine, don’t rely on front-loading alone. Bosch and Electrolux stacking kit compatibility guidance applies to specific appliance dimensions and model numbers.
Whether you’re fitting out a kitchen, bathroom or narrow utility room, first identify what’s limiting the installation, then compare the model’s dimensions with its installation diagram. Capacity and usage information can then help you choose between the appliances that will actually fit in your home.
| Factor | What to check | What matters to shoppers |
|---|---|---|
| Width | Overall width and the clearance needed to open the lid on a top-loader. | If my space is narrow, I need a machine that fits without blocking access to the top. Around 29% of shoppers prioritise this width constraint. |
| Depth | The depth of the connected appliance and the space needed in front of the door. | In a small room, I want to avoid a front-loader sticking out into the walkway while still being able to open the door. Depth is the priority for around 29% of shoppers. |
| Under-counter or stacked installation | Clearance under the worktop, or compatibility between both appliances and the stacking kit. | I want to fit the machine under a worktop or save floor space with a stack, without assuming that any front-loader will do. Nearly 24% of shoppers put this installation option first. |
| Capacity and usage | Capacity in kg to suit your usual laundry loads; the model’s energy label and durability index. | If a smaller appliance means I have to do very small loads, the space saved won’t meet my laundry needs. For around 18% of shoppers, maintaining useful capacity and considering how the appliance will be used come before choosing the smallest format. |
A machine may fit into its alcove but leave too little room to open the door or lid. Connections can also increase the depth needed for installation.
Measure the space and the door-opening area, then check the model’s installation diagram before ordering.
Stacking kits have their own requirements: Bosch specifies a washing machine depth of more than 55 cm for kit 17007748, while Electrolux gives a range of 52 to 67 cm for kit E1WYHSK2, designed for the brand’s front-loading appliances. These dimensions alone aren’t enough to confirm that a particular pair is compatible.
Before planning a stack, check the model numbers of the washing machine, tumble dryer and kit against the manufacturer’s guidance.
An unsuitable kit could mean having to reconsider one of the appliances.
A drum that’s too small for your usual loads could mean splitting your laundry across more cycles. ADEME advises choosing a capacity that meets your actual needs and also comparing the water and energy use, noise and spin performance shown on the energy label.
Think about your typical loads before choosing a compact model, then compare the specifications of models that fit your space.
An older repairability rating and a washing machine’s durability index don’t assess exactly the same criteria. For purchases in France, the Ministry for Ecological Transition presents the durability index as the applicable indicator for this category since 8 April 2025.
Check the index for the model you’re considering and the details behind its criteria, rather than comparing ratings that measure different things.
These examples can help you compare formats and installation requirements for specific models and accessories. They don’t mean that every model from a brand has the same features.
The brand offers a narrow top-loader to compare, as well as a separate stacking kit for certain front-loading appliances.
The front-loading WGE03201FR and stacking kit 17007748 illustrate two separate checks: the washing machine’s dimensions and whether it’s suitable for stacking.
The brand’s examples can help you compare shallower front-loaders if you have enough width for this type of appliance.
Candy’s overview of top-loading, slim and compact formats can help you find an appliance to suit the dimension you’re short on.
This front-loader may suit anyone who wants a door-opening design and an 8 kg capacity. Before choosing it for a small space, compare its installation dimensions and the clearance needed to open the door with your measurements. Don’t assume it’s suitable for stacking.

Worth considering if you want a front-loading machine and its 8 kg capacity suits your usual laundry loads.
The model name indicates a 1,400 rpm spin speed, 16 programmes and a steam function. Check the manual for the installation dimensions, door clearance and any compatibility requirements if you’re considering stacking it.
Measure the available width, depth and height, as well as the space needed to open the door or lid. Check where the connections are, too, and allow for the clearances specified in the model’s manual. Its external dimensions alone don’t guarantee a practical installation.
Yes, as long as the model and the space under the worktop meet the manufacturer’s installation instructions. Check the available height in particular and allow access to the connections. A shallow depth alone doesn’t guarantee that the machine can be installed under a worktop.
No. Choose a stacking kit that’s declared compatible with both model numbers, and follow its installation instructions. The kits from Bosch and Electrolux have depth requirements; similar dimensions don’t replace a compatibility check.
Check the durability index for the model sold in France and, if you’re comparing several appliances, look at the details of the criteria. According to the Ministry for Ecological Transition, the index has applied to washing machines since 8 April 2025. Don’t confuse it with an older repairability rating.
