To stack two appliances, choose front-loading models of similar dimensions, with the tumble dryer on top of the washing machine. Check that the exact model numbers are compatible with the stacking kit and consult the manuals. You’ll also need a suitable space and floor. If these conditions aren’t met, a washer-dryer may be a suitable alternative, provided its drying capacity is enough for your loads, as this may be lower than its washing capacity. For the Bosch WNG25402FR, Bosch states a capacity of 6 kg for wash-and-dry cycles, compared with 10.5 kg for washing.
You want to free up floor space while keeping two appliances. The available height and compatibility of the models with the stacking kit will determine whether this set-up is possible. Bosch Home Appliances France recommends checking model compatibility in the manual.
If you can’t install a stacked set-up, compare the washer-dryer’s drying capacity with the size of your usual loads. For the WNG25402FR, Bosch states a capacity of 10.5 kg for washing and 6 kg for wash-and-dry cycles.
Available space alone won’t tell you whether the installation is suitable : the electrical set-up and the conditions specific to a room with moisture also matter. Have your specific plans checked if necessary.
Consider this : if you can install two front-loading appliances and check that they’re compatible with the exact stacking kit you’ve chosen.
Bear in mind : you’ll need two machines, a suitable stacking kit, enough height and convenient access.
Consider this : if you can’t install two appliances and the model’s drying capacity is enough for your loads.
Check : the washing and drying capacities separately, as they may differ.
| Consideration | What to check | Who is this most important to ? |
|---|---|---|
| Compatibility and stability | Check the exact model numbers of both appliances and the stacking kit in the manuals. The appliances must be front-loading and of similar dimensions, with the tumble dryer positioned above the washing machine. | I want to keep two machines but avoid an incompatible or unstable stack. Around 36 % of consumers prioritise the compatibility and stability of a stacked set-up. |
| Space and installation | Measure the height, width and depth, as well as the space needed to access the appliances. Also check the connections, ventilation and position of the sockets. | In a small room, I need to check that the appliances and their connections will fit without restricting access. Around 29 % of consumers prioritise how well the appliances fit the room. |
| Drying capacity | For the exact model, compare the drying capacity in kilograms with its washing capacity, then consider the size of your usual loads. | If I regularly dry full loads, I compare the drying cycle’s capacity with the amount of laundry I usually wash. Around 14 % of consumers put drying capacity first. |
| Energy use and running costs | Check the energy label and product information for the exact models, as well as the type of tumble dryer. Compare appliances in the same category, taking into account how often you’ll use them. | When choosing an appliance I’ll use regularly, I want to consider the energy used for drying alongside my own habits. Around 14 % of consumers prioritise running costs. |
| Using a single appliance | If you choose a washer-dryer, check its dimensions and the load it can dry, not just its washing capacity. | If I can’t install a stack, one machine needs to be able to wash and dry the amount of laundry I need it to. Around 7 % of consumers prioritise this option. |
Manufacturers may restrict a stacking kit to specific models or conditions. Similar width or depth alone doesn’t confirm that two appliances can be safely stacked together.
Before choosing this set-up, check the full model numbers of both appliances and the stacking kit in the manuals and with the manufacturer.
A stack also needs sufficient height and practical access. In a bathroom, you’ll also need to consider the room’s layout and the position of the electrical connections.
Measure the available space, including access to the appliances, and have the room’s installation conditions checked if necessary.
For the WNG25402FR model, Bosch states a capacity of up to 10.5 kg for washing and 6 kg for wash-and-dry cycles. So, for this model, you’ll need to consider the load it can dry separately.
Compare the capacity of the cycle that washes and dries with your usual loads, rather than relying only on the washing capacity in kilograms.

No, similar dimensions aren’t enough to confirm compatibility. Samsung France lists the SKK-ZSD kit for the WF90F09C4SU3 and DV90F09F4SU3 models, while Bosch advises checking the WTZ27510 kit’s compatibility by model number.

Compare the appliances needed for each option, adding a suitable stacking kit for a stacked set-up, then look at the energy information for the exact models in light of how you’ll use them. Energy labelling for the appliances in question is governed by the rules described by the DGCCRF ; compare products in the same category.
