How to choose a portable washing machine for your caravan or motorhome: the types, the specs to expect, power draw and capacity, and which one suits how you travel.
A full-size washing machine is far too bulky and heavy for life on the road, but a portable caravan washing machine solves the problem neatly. They are compact, relatively inexpensive, and save hours of hand-washing when you are touring in a motorhome or staying in a static caravan. Most run on low power and can be filled by hand or from a hose, so you are not tied to a permanent plumbed supply. This guide covers how they work, the main types, the specs to expect, and how to choose one that suits your van and your power setup.
What a portable caravan washing machine is
It is a small, free-standing washer that is not permanently connected to a water supply or drainage system. Instead of plumbing, you fill it from a tap, a hose or a container, and drain it into a sink, a bucket or the caravan’s waste outlet. That makes it easy to use on a pitch, on a worktop, or even outside the van in good weather, then pack away when you are done. If you only head away a few times a year, or you are borrowing or hiring a van for a single trip, it is worth remembering you can also arrange temporary motorhome insurance for as little as a day rather than paying for a full annual policy.
How do I set up a mini portable washing machine?
The key difference from a home machine is that it is not fixed to the mains water and waste. You connect it to a water source with a hose, or simply add water by hand. The drain hose goes into a sink, or straight to the caravan’s outdoor drain if you can reach it. Some of the smaller single-tub models are even simpler: you just empty them out at the end of the wash and spin cycles.
The main types of portable washer
Wash and spin side by side
Two compartments, one to wash and one to spin-dry, so you lift the load straight from one to the other. The most common caravan choice, with quick cycles and no plumbing needed.
Best for: regular touring laundry. Watch: a bigger footprint than a single tub.
Smallest and lightest
One drum that washes, then drains, with no separate spinner. The most compact and easiest to store, though clothes come out wetter.
Best for: couples, small loads, tight storage. Watch: longer drying time afterwards.
Full power on hookup
A higher-powered portable that runs from a 230V hookup like a small home machine, with proper wash and spin cycles and faster spin speeds.
Best for: stays on serviced pitches with hookup. Watch: too power-hungry to run off a leisure battery alone.
Typical specs to expect
Portable washers vary more than you might think. These are the typical figures across the compact twin-tub, mid-size and larger 230V models on the market, useful as a benchmark when you are comparing one against another.
| Spec | Compact twin tub | Mid-size / larger |
|---|---|---|
| Total capacity | ~4.5 kg (2.5 kg wash / 2 kg spin) | ~6 kg (3.6 kg wash / 2.5 kg spin) |
| Wash cycle | ~15 min, dial timer | ~15 min, dial timer |
| Spin cycle | ~3 min | ~5 min |
| Power draw | ~240 W wash / 120 W spin (low draw) | Higher, 230V mains recommended |
| Spin speed | up to ~1300 RPM | up to ~1300 RPM |
| Dimensions (WxDxH) | ~54 x 38 x 55 cm | ~60 x 38 x 69 cm |
| Carry weight | ~11 kg | heavier |
| Plumbing | None, fill by hose or hand | None, gravity or pump drain |
What to look out for when buying
Size and where it fits
This is the first thing to work out. Portable washers are compact but not tiny: a typical twin tub is around 54 to 60cm wide, 38cm deep and 55 to 69cm tall, so measure your worktop or floor space, and remember you also need somewhere to store it between washes. With a carry weight of around 11kg on the smaller models, it is light enough to lift in and out, but not something you want underfoot all trip.
Load capacity
Capacity is quoted in kilograms, and on a twin tub it is split between the washer and the spinner, so a 4.5kg machine typically means about 2.5kg of washing and 2kg of spinning at a time, while larger models reach around 6kg total. Match the size to how many of you are travelling and how often you will wash, rather than buying the biggest you can fit.
Wash and spin cycles
One of the real advantages over hand-washing is speed. Most run a short wash cycle of around 15 minutes and a spin of roughly 3 to 5 minutes, set on a simple dial timer, with spin speeds up to around 1300 RPM on the better units. Look for a quick-wash option to save time and water on a busy touring day.
Ease of use and draining
This is functional kit, so you do not need the electronics of a domestic machine, just a clear wash and spin selection. Check how it fills and drains: most have no plumbing requirement and are filled by hose or by hand, then drained into a sink, a bucket or the van’s waste outlet. A gravity-drain function is a handy feature to look for, and some single-tub models simply tip out at the end.
Power draw and your leisure battery
This is the deciding factor for off-grid touring. A low-draw mini twin tub may use around 240W to wash and 120W to spin, while a full 230V portable pulls far more and really needs a mains hookup. Choose a model that is kind to your leisure battery, as lower consumption saves energy and prolongs battery life. Away from hookup, a low-power washer can be run safely from a pure sine wave inverter, the same kit that powers other sensitive electronics on board, and pairing it with a solar panel setup or a charged-up leisure battery keeps you running for longer. If you regularly run heavier appliances off-grid, a silent generator is the other way to keep the power up.
Is it worth it for the contents value?
A portable washing machine is one more appliance that adds to the value of everything you carry. Once you tot up the washer, the microwave, the TV, the leisure battery kit and the outdoor gear, the figure climbs faster than most owners expect, and many policies cap contents cover as standard, often around the £3,500 mark. It pays to total what you actually carry and check it against your limit, and to see what the average cost of caravan insurance looks like before you renew, so you are not caught short if the worst happens.
