Stack a front-loading washing machine and tumble dryer only if a stacking kit is confirmed as compatible with their exact model numbers and the washing machine can sit securely on the floor. A pair designed for stacking makes it easier to choose a kit, but you should still check the manuals. If you only have room for one appliance, a washer-dryer avoids the need for a stacked pair, but its drying capacity is lower than its washing capacity.
You want to combine washing and drying without using up two floor spaces. Measure the available space, then check the clearances specified in the manuals and make sure the kit is suitable for both appliances. UFC-Que Choisir cites saving space as a reason to stack them.
Keeping your existing washing machine or tumble dryer doesn’t guarantee that a new model will fit the same stacking kit. Bosch, Miele and Siemens product information shows that compatibility can depend on the series or kit model number, even when the dimensions seem similar.
If you can’t install a stacked pair as specified, a washer-dryer combines both functions in one appliance. However, UFC-Que Choisir points out that its drying capacity is lower than its washing capacity.
For a stacked pair, first check the space available and confirm that both appliances are compatible with the kit. Then make sure the tumble dryer will be easy to reach. If you only have room for one appliance, compare the washing and drying capacities of a washer-dryer.
| Factor | What to check before buying | Who this matters to |
|---|---|---|
| Compatibility and stability | Confirm that the kit is suitable for the exact model numbers of both appliances and the series specified by the manufacturer. Place the washing machine on a flat, rigid and solid floor, with the tumble dryer on top. | If I’m keeping one appliance and adding another to my stacked pair, I want to be sure the new model can be secured with the right kit. Around 36% of consumers prioritise compatibility and stability. |
| Space and tumble dryer installation | Measure the available space and check the clearance and ventilation requirements for your chosen model. Also check any depth restrictions that apply to the kit. | In a narrow utility room, I want to free up floor space without making it difficult to install my tumble dryer; around 29% of consumers put this first. |
| Access to your laundry | Check the final height, door clearance and access to the controls. If you’d like a pull-out shelf, choose one that comes with a compatible kit. | If I handle laundry frequently, I need to be able to reach the tumble dryer drum when it’s raised; around 21% of consumers prioritise easy access for everyday use. |
| One appliance only | For a washer-dryer, compare the washing and drying capacities separately, as well as the programme times for the model you’re considering. | When I only have room for one appliance, I’d rather forgo a stacked pair while keeping both functions; around 14% of consumers make this their priority. |
Similar dimensions don’t prove that a kit can safely secure the pair you’ve chosen. Bosch, Electrolux, Miele and Siemens publish requirements that may relate to depth or specific appliance series.
Note down the full model numbers of both appliances and check the kit’s compatibility list before ordering.
Miele says the washing machine must stay on the floor to keep its vibrations stable, with the tumble dryer on top in a stacked pair fitted with a stacking kit.
Follow this order and the instructions for the kit and both appliances. Never simply place the tumble dryer on top of the washing machine.
According to UFC-Que Choisir, a washer-dryer’s drying capacity is lower than its washing capacity. This means you may need to plan differently when drying a full load.
Compare both capacities and the programme times. For the model you’re considering, also check the information on water use during drying.
A stacked pair takes up less floor space, but the tumble dryer door and controls are higher up. A pull-out shelf won’t solve the problem if you can’t reach the drum.
Measure the height once the appliances are stacked and check that the doors can open before choosing a kit with or without a shelf.
The requirements published for these kits show why you should choose one based on the appliance model numbers, not just the brand.
Bosch offers stacking kits with or without a shelf, depending on the model.
The Electrolux E1WYHSK2 kit includes a shelf and is designed for a pair of front-loading appliances that meet the manufacturer’s requirements.
Miele stacking kits specify particular appliance series, so you can look for a kit based on the pair you’re considering.
Siemens offers stacking kits with requirements that vary by model.
Not based on width alone: the kit must be confirmed as compatible with both appliances’ model numbers. Requirements published by Bosch, Electrolux, Miele and Siemens show that depth and permitted or excluded series can matter too.
The washing machine stays on the floor to keep its vibrations stable. Miele says that, in a stacked pair with a stacking kit, the tumble dryer goes on top. You should also follow the instructions for your specific appliances and kit.
No, you don’t need a shelf for every stacked pair. If your compatible kit includes one, it can make handling laundry easier. Check its load limit and make sure you can reach the tumble dryer.
Not necessarily. First, choose a tumble dryer that meets the stacking and installation requirements for your pair. UFC-Que Choisir highlights the low electricity consumption of heat pump models; then check the specifications and manual for the model you’re considering.
No. It takes up the space of one appliance, but according to UFC-Que Choisir, its drying capacity is lower than its washing capacity. Before choosing one, check the programme times and the information on water consumption during drying for the specific model.
