Choose a washer-dryer if you only have one floor space available and are happy with a lower drying capacity than washing capacity, along with generally longer cycles. If you have enough vertical space, an approved stacking arrangement with a separate tumble dryer can preserve floor space, but it requires compatible appliances, a suitable stacking kit, a stable floor and proper ventilation.
If you only have one floor space available, a washer-dryer is the first option worth considering. UFC-Que Choisir points out, however, that its drying capacity is lower than its washing capacity, so the washing capacity alone is not enough to make your choice.
A stacked arrangement can retain the washing machine’s floor footprint while adding a tumble dryer. It requires sufficient height, a stable floor and a kit compatible with the two exact appliance models.
A separate solution, particularly a heat pump model, is worth comparing if the reduced capacity or longer cycle of a washer-dryer could slow down your laundry routine. UFC-Que Choisir distinguishes heat pump tumble dryers by their lower electricity consumption compared with traditional condenser models.
Start by measuring the space you actually have available, then compare each appliance’s drying capacity, full-cycle data and installation requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Floor space | Measure the width, depth, height and door clearance. A stacked arrangement also requires a rigid floor, sufficient height and a kit stated to be compatible. | I want to dry laundry without using a second floor space. A washer-dryer takes up one space; a stacked arrangement saves width but uses vertical space. |
| Capacity and routine | Compare the washing and drying capacities separately in kg, as well as the duration of the wash-and-dry programme. For two appliances, match the tumble dryer’s capacity to the volume you usually wash. | I want to avoid removing part of a large wash before drying or waiting too long between loads. |
| Water and electricity | For a washer-dryer, check the label and the full wash-and-dry cycle information. For a separate tumble dryer, check the technology, consumption and stated duration for the exact model. | I want to keep running costs down without relying solely on washing-only data. UFC-Que Choisir states that drying in a washer-dryer can use water. |
| Safe installation | For a stacked arrangement, confirm the exact model references, kit, dimensions and clearances specified in the manuals. The tumble dryer must be placed above the washing machine. | I want a stable installation in a suitable room. The appliances must be front-loading, similar in size and explicitly compatible, according to UFC-Que Choisir. |
A washer-dryer may be able to wash more laundry than it can dry. A full load may therefore need to be split before drying, increasing the total time.
Always compare both capacities in kg. If you want to start a cycle and leave it running without intervening, load the drum according to the drying capacity.
A similar width guarantees neither stability nor mechanical compatibility. Some kits require a minimum depth or exclude certain models.
Note the exact model references, consult the manuals or the manufacturer’s compatibility tool, then check the required kit before installation.
Data for a washing-only programme does not necessarily describe the water, electricity or duration of a complete wash-and-dry cycle.
For a washer-dryer, check the combined-cycle information. For a separate tumble dryer, compare the technology, capacity, duration and installation requirements.
A vented tumble dryer requires an opening to the outside or a suitable duct, unlike condenser and heat pump appliances.
If your home has no suitable outlet, consider a condenser or heat pump model and follow the clearances specified in the manual.
Worth considering for a separate solution or stacked arrangement, as Bosch France offers heat pump tumble dryers and stacking kits identified by reference.
Worth comparing for washer-dryers with different washing and drying capacities, including models advertised as 8/5 kg.
Worth considering for washer-dryers offering combined programmes and several washing/drying capacity combinations.
Joybuy options for a small home: a washer-dryer for a single floor space, plus separate condenser or heat pump tumble dryers to consider in a dedicated space or an approved stacked arrangement.
Image unavailable
A two-in-one option for a single floor space and consecutive washing and drying.
Advertised capacity: 8 kg for washing and 5 kg for drying; stated depth: 520 mm. Check the actual width, full-cycle data and the space required to open the door before buying.
Image unavailable
Worth considering for separate drying of regular loads when space allows for a second appliance or a compatible stacked arrangement.
Advertised capacity: 8 kg; heat pump technology. The 2-in-1 Easy Cleaning filter and direct connection to the water outlet are advertised; check the dimensions, ventilation, cycle durations and stacking compatibility.
Image unavailable
A high-capacity separate option advertised for households that prioritise the volume of laundry dried.
Advertised capacity: 10 kg; heat pump technology, double-layer lint filter, adjustable drying levels and refresh programme. Consult the manual for the dimensions, ventilation and programme durations.
Image unavailable
Worth considering for separate drying of everyday loads, without the need for an appliance advertised as requiring external venting.
Advertised capacity: 8 kg; heat pump technology, three drying levels and double-layer filter. Check the dimensions, required clearances, cycle durations and compatibility before installing in a stacked arrangement.
Image unavailable
A separate condenser option for precise planning in a small space.
Advertised capacity: 8 kg; advertised dimensions: 60 × 65 × 85 cm; reversible door and water collection tank advertised. Check door clearance, ventilation clearances and stacking-kit compatibility.
No, not with a full 8 kg load: the drying capacity is limited to 5 kg. Load the drum according to the drying capacity or remove some of the laundry before starting the drying cycle. The LG F854M20WR specification, for example, states 8 kg for washing and 5 kg for drying.
No. Condenser tumble dryers, including heat pump models, can be installed without an external connection. A vented model, on the other hand, requires an external opening or suitable duct.
No. The tumble dryer must be placed above the washing machine. UFC-Que Choisir also specifies that the appliances must be front-loading, similar in size and paired with a compatible stacking system.
Yes. France’s Ministry for Ecological Transition states that products legally required to display an energy label must show this information clearly in relevant advertising. For a washer-dryer, make sure the data being compared relates specifically to the wash-and-dry cycle.
