Laundry is one of those household jobs that feels like it never ends. In fact, a survey found that we spend about 102 minutes a week on laundry, which adds up to 88 hours a year. That's enough time to fly to New York, spend a long weekend exploring, and fly home again.
That's why having the right laundry setup can make such a difference. But is it better to choose a space-saving washer-dryer, or a separate washing machine and tumble dryer that can tackle bigger loads? We'll break down the key differences to help you find the best fit for your home, budget and routine.
What is a washer-dryer combo?
A washer-dryer does exactly what you’d expect – washing and drying in one appliance. Once the wash cycle has finished, it can automatically move on to drying without any extra input. This makes it a popular choice for smaller homes that don’t have room for two separate appliances. Just bear in mind that most models can wash more than they can dry, so you might need to take some items out before starting the drying cycle.
What are separate washing machines and tumble dryers?
Separate laundry appliances split washing and drying between two machines. Because each appliance is designed for a specific job, they can usually handle larger loads and deliver stronger drying performance than a washer-dryer combo.
If you've got multiple loads to get through, separate appliances can save time by letting you wash one load while another is drying. Not sure which models to choose? Take a look at our guides to the best type of tumble dryer and best washing machines. And if you're worried about space, many washing machines and tumble dryers can be mounted on top of each other using a stacking kit.
Which option is best if space is limited?
For many people, space is the deciding factor. A washer-dryer takes up about the same room as a standard washing machine, making it ideal for smaller homes. If you're considering one, our washer-dryer buying guide can help you find the right model.
Separate appliances need more room, but you can reduce their footprint by stacking them vertically using a stacking kit. If you're exploring this option, our tumble dryer buying guide can help you choose the right dryer for your home. But if space is tight, a washer-dryer is likely the better fit.
Which option cleans and dries better?
Both options will leave your clothes clean, but separate appliances usually have the edge when it comes to drying. Dedicated tumble dryers tend to be faster, handle larger loads better and can be more energy efficient, especially heat pump models.
On the other hand, washer-dryer drying cycles tend to be slower because the same drum is used for both functions. That said, they can still be a handy alternative to air drying, especially during colder months or when outdoor drying isn't possible.
Which option costs less to buy and run?
A washer-dryer is usually cheaper upfront, as you're only buying one appliance. If you only do a few loads a week, it's the better-value choice. Separate machines cost more to start with, but they can be worth the extra spend if you're constantly washing and drying. Separate appliances can also be more economical to run, particularly if you're using a heat pump tumble dryer.
Running costs aren't the only long-term expense to think about. If a washer-dryer breaks down, you lose both functions at once. But with separate appliances, you can keep washing or drying while the other machine is being fixed.
Which option is more convenient?
A washer-dryer keeps everything in one machine, helping to make your laundry routine simpler. Just load your clothes, select a programme and let it handle both washing and drying. The downside is that wash-and-dry cycles can take longer to complete.
Separate appliances need an extra step, as you'll need to move clothes from the washing machine to the dryer. However, they let you wash one load while the other is drying, helping you get through your laundry basket faster.
If convenience means less effort, choose a washer-dryer. If it means getting laundry done quicker, separate appliances are the better choice.
Which option is right for you?
A washer-dryer could be the better choice if you:
Live in a flat or smaller home
Have limited space
Only do a few loads each week
Want an all-in-one appliance
Prefer a simpler laundry routine
Separate appliances may suit you better if you:
Have a larger household
Wash clothes several times a week
Need larger load capacities
Want the best possible drying performance
Like the flexibility of washing and drying at the same time
If saving space is your priority, a washer-dryer is hard to beat. If you're always working through piles of laundry, separate appliances may be a better fit.
