If you have enough vertical space and the appliances and stacking kit are compatible, a separate tumble dryer stacked on top of your washing machine avoids the reduced drying capacity of a washer-dryer. If you can only fit one appliance, choose a washer-dryer, checking its washing capacity, drying capacity and the space needed to open the door separately.
If floor space is limited but there’s room above, check the model numbers of both appliances, the stacking kit and access to the door. Whirlpool specifies that the washing machine must stay on the floor; Bosch and Electrolux kits also have their own compatibility requirements.
If you can’t fit two appliances, even stacked, a washer-dryer takes up just one space. However, UFC-Que Choisir points out that its drying capacity is lower than its washing capacity, so you may not be able to dry a full wash in one go.
For towels or frequent family-sized washes, compare how much laundry each cycle can actually dry. A separate tumble dryer is worth considering if a washer-dryer’s drying limit would regularly mean taking some of the washing out before drying.
In a compact utility room, start with the space you can actually use, then compare drying capacity and the day-to-day considerations of each setup.
| What matters | What to check | Who this matters to |
|---|---|---|
| Creating a stable stack | Measure the available height and depth; check the manuals to confirm that the front-loading appliances and stacking kit are compatible. | If there’s not enough width but you can make use of the height, the priority is stacking the appliances securely. Around 33% of consumers put this need first. |
| Using just one space | Compare the washer-dryer’s washing and drying capacities, as well as its depth and door clearance. | If stacking isn’t practical, being able to wash and dry with one appliance becomes crucial; around 27% of consumers prioritise this requirement. |
| Keeping up with the washing | Compare the stated drying capacity with the loads you usually wash, and check how long the programmes you’re considering take. | With frequent or large loads, having to remove some washing before drying can disrupt your day. For around 20% of consumers, capacity and cycle times come before other considerations. |
| Managing energy use and water | Check the model’s energy label and find out how to access the tank or connect a condensate drain hose, if applicable. | Having to empty a hard-to-reach tank or frequently using a cycle with unsuitable energy consumption can affect your choice; around 20% of consumers prioritise energy use and condensate management. |
A condenser tumble dryer, with or without a heat pump, is still a second appliance that needs space. Compare specific models rather than assuming how much energy they use based on their technology alone. If you’re considering a vented dryer, don’t choose one until you’ve confirmed that you have the necessary air outlet or external vent; Boulanger outlines the different installation requirements for each technology.
A washer-dryer may be able to wash more laundry than it can dry. For example, Electrolux lists an 8 kg washing capacity and a 5 kg drying capacity for its EW7IW2856BG.
Choose based on the amount of laundry you want to dry, and check whether you’ll need to remove some of the load before starting a drying cycle.
This difference may mean running extra drying cycles.
Similar depths aren’t enough to confirm compatibility. Whirlpool requires a fixing kit, while Bosch and Electrolux accessories have specific conditions for the models they can be used with.
Keep the washing machine on the floor and check the exact models of both appliances in the kit instructions before stacking them.
An appliance may fit in the available space but still be difficult to load or maintain if you can’t easily access the door, filter or tank.
Also measure the delivery route, door clearance and the clearances specified in the manual. For a stacked setup, check the height of the upper door too.
This technology doesn’t remove the need to allow space for the appliance, maintain it or collect or drain condensate.
Compare the energy label and installation instructions for the specific model, then make sure you can access the parts that need maintenance.
Worth considering for a separate heat-pump tumble dryer and a stacked setup using a specified accessory.
Offers separate heat-pump tumble dryers, among other appliances, as well as stacking advice.
Its range includes the 9 kg RH9X56WH heat-pump tumble dryer, which you can compare based on your available space and preferred programmes.
Offers both a washer-dryer and accessories designed for stacking front-loading appliances.
These appliances illustrate the choice between a washer-dryer that takes up one space and separate tumble dryers. For each separate dryer, check its dimensions and whether it can be safely stacked before choosing this setup.

Worth considering if you can only fit one appliance. It’s listed as 11 kg for washing and 6 kg for drying, so make sure the load you want to dry is within that second limit. Also measure the space and allow enough room to open the door.

This separate tumble dryer has an 8 kg capacity and a C energy rating. Before planning a stacked setup, check its dimensions and confirm in the manuals that the washing machine and stacking kit are compatible.

This separate drying option has an 8 kg capacity and a D energy rating. Check its dimensions and clearances and, if you plan to stack it, confirm that the appliances and kit are compatible according to their documentation.

This 8 kg model gives you another separate drying option to consider. Measure the space, check that you can access the appliance during use and consult the manuals to confirm compatibility if you’re planning a stacked setup.
No. When stacking appliances, the washing machine must stay on the floor and the tumble dryer must be secured with a compatible kit. Check the model numbers and approved dimensions in the manuals for both appliances and the kit. The requirements set out by Whirlpool, Bosch and Electrolux mean that not all combinations are interchangeable.
Not necessarily: its drying capacity may be lower than its washing capacity. UFC-Que Choisir highlights this difference, and Electrolux lists the EW7IW2856BG as 8 kg for washing and 5 kg for drying. Check both capacities for the model you’re considering.
It depends on the technology you choose. Don’t buy a vented tumble dryer until you’ve confirmed that you have the necessary external outlet or ducting. For a condenser or heat-pump model, follow the instructions on ventilation, clearances and collecting or draining condensate.
Check the model’s connection requirements in its manual, then make sure they’re suitable for the room’s electrical installation. If you’re unsure, have the installation checked before deciding where to put the appliance.
Compare the labels and product specifications using the same scale, as well as the stated energy consumption for the specific models. Don’t assume that a rating on an older product sheet is directly comparable with one based on a newer scale.
