If you only have room for one appliance on the floor, a washer-dryer combines both functions, provided you’re happy with a lower drying capacity than washing capacity. Two stacked appliances are better suited to frequent washing, as long as you’ve confirmed that they’re compatible and that the stacking kit and installation are stable. A separate tumble dryer needs its own space; the right technology depends, among other things, on whether or not you have an external vent.
If you only have room for one appliance on the floor, a washer-dryer means you won’t need to find space for a second one. However, you’ll need to size your loads according to its drying capacity, which is generally lower than its washing capacity, as UFC-Que Choisir points out.
With two dedicated appliances, you can dry one load while another is being washed. If you need to stack them, UFC-Que Choisir recommends checking the dimensions, compatibility and stability of the setup.
If there’s room elsewhere in your home for a tumble dryer, compare the cycle times and energy consumption for programmes suited to your laundry. Also check the installation requirements for your chosen technology, particularly if the room has no external vent.
Start with the space you actually have, then consider how much laundry you need to dry and any limitations of the room. The three options suit different laundry routines.
Consider it if: you only have space for one appliance on the floor and want to wash and dry without transferring the laundry.
Bear in mind: the drying capacity is lower than the washing capacity, so you may need to split a full wash load before drying it.
Consider it if: you often dry several loads and have enough height for a stacked setup.
Bear in mind: the tumble dryer must be accessible when stacked, and the appliances and stacking kit must be compatible.
Consider it if: you have a separate space on the floor for the appliance.
Bear in mind: according to UFC-Que Choisir, a vented model needs an opening or duct to the outside. A condenser model doesn’t need this connection, but must be installed in accordance with its instructions.
| Consideration | What to check | Who is it for? |
|---|---|---|
| Floor space | Full appliance dimensions; washing and drying capacities listed separately in kg. | When there’s only one free space, I want to combine both functions without having to make room for a second appliance. Around 40% of consumers prioritise a small floor footprint. |
| How often you do laundry | Drying capacity in kg and the duration of the programme that suits your fabrics and load. | If I do several loads in a row, I want to be able to dry laundry without waiting for each new wash to finish. For around 30% of consumers, drying throughput is the main concern. |
| Installation and use | Compatibility of the stacked setup or the presence of an external vent, depending on the appliance; programme energy consumption and ventilation instructions in the manual. | In a room with limited installation options, I want to choose an appliance I can use in accordance with its instructions while keeping an eye on energy consumption. For around 30% of consumers, room suitability and energy use come before other criteria. |
A washer-dryer has a lower drying capacity, so you may need to remove some laundry from a full wash load or dry it in two batches. UFC-Que Choisir highlights the difference between the two functions.
Compare both capacities in kg with the amount of laundry you want to dry in one go.
A kit may only be suitable for certain dimensions or model numbers. Stacking appliances in a configuration that isn’t designed for them could make the setup unstable.
Check the full model numbers, read the manuals and choose a kit only if its compatibility is confirmed. Place the tumble dryer on top of the washing machine, on a flat, stable floor.
Remember to allow space for the kit and to access the tumble dryer when it’s stacked.
According to UFC-Que Choisir, this type of tumble dryer needs an opening to the outside or access to a ventilation duct.
If the room doesn’t have one, compare condenser models instead, including heat pump models, then check the installation and ventilation instructions for each appliance.
Cycle time, energy consumption, load size and maintenance are separate criteria in UFC-Que Choisir’s test protocols. A single cycle time doesn’t tell you everything about the programme.
Compare programmes for similar loads and fabrics, then check the installation requirements separately.
Worth considering if you need both functions in a single appliance.
Worth considering if you’re planning a stacked setup with a stacking kit specifically confirmed as compatible.
Worth considering for a stacked setup with an adaptor suited to your chosen models.
Worth considering if you’re checking the installation requirements for a separate tumble dryer in the space available.
These appliances combine washing and drying in a single space on the floor. For each one, compare the amount of laundry you want to dry with the stated drying capacity, then measure the space available before choosing.

This washer-dryer is suited to a single space if your loads for drying are no more than 6 kg. The product name lists 10 kg for washing, 6 kg for drying and a D rating. Check what the rating applies to, as well as the duration and energy consumption of the programme you plan to use.

According to the product name, this washer-dryer can wash up to 11 kg, but its stated drying capacity is still 6 kg. If you plan to dry a full wash load, bear this difference in mind. Also check the dimensions and cycle information for the full model number.

This washer-dryer combines both functions in a single space, with a stated washing capacity of 10 kg and drying capacity of 6 kg. The product name mentions Zeo-Cycle and LintClear; check the dimensions and the duration and energy consumption of the programmes suited to your laundry.

This white washer-dryer is suited to a home where there’s room on the floor for only one appliance. It lists 10 kg for washing and 6 kg for drying; the product name also mentions Zeo-Cycle, LintClear and automatic dosing. Check the dimensions and cycle information before choosing this version.
Not necessarily: as UFC-Que Choisir explains, the drying capacity is lower than the washing capacity. Compare the two figures for your chosen model. If the wash load is larger than its drying capacity, remove some laundry before starting the drying cycle.
No. The stacking setup needs to be suitable for the chosen models, dimensions and kit. Check the manuals for both appliances and the kit instructions. The tumble dryer goes on top of the washing machine, and the setup must be stable, in line with guidance from UFC-Que Choisir and Bosch Home Appliances France.
No. According to UFC-Que Choisir, a vented model needs an opening to the outside or a ventilation duct, while a condenser tumble dryer, including a heat pump model, doesn’t need this connection. In all cases, follow the installation and ventilation requirements in the manual.
Check the manual to see how easy it is to access the parts that need maintenance, including the filters and, depending on the appliance, the water tank. UFC-Que Choisir includes ease of maintenance in its assessment protocols. If you use the tumble dryer frequently, make sure you can carry out these tasks where you plan to install it.
