The awkward gap beside a washing machine looks like useful storage until an ordinary round basket leaves half of it empty. A slim laundry basket solves that problem by turning a narrow strip of floor into vertical capacity. The best designs stay upright, hold a realistic wash load and remain easy to empty even when wedged between furniture.
Our best overall pick is the SpaceAid 65L Slim Laundry Hamper. It measures just 20.3cm across its narrow side, yet the tall body provides a stated 65-litre capacity. A lid keeps everyday laundry out of sight and internal rods help the fabric hamper retain its shape. If you prefer to lift out a bag rather than move the whole basket, the efluky 63L is the better fit.
This is an editorial comparison based on current Amazon UK listings and published product specifications, not a hands-on laboratory test. We prioritised the narrowest dimension, capacity, access, carrying method, structure and how convincingly each design solves a small-home problem.

Comparison at a glance
| Slim laundry basket | Dimensions (L x W x H) | Capacity | Construction | Best for |
|---|---|---|---|---|
| SpaceAid 65L | 40.6 x 20.3 x 71.1cm | 65L | Structured fabric, bamboo accents and lid | The narrowest gaps |
| efluky 63L | Approx. 41 x 22 x 70cm | 63L | Fabric, bamboo frame, lid and removable liner | Carrying one bag to the machine |
| HAIXIN 50L | 41.4 x 21.4 x 62cm | 50L | Rigid plastic, lid, handle and wheels | Rolling laundry on one level |
| Caroeas 50L | Approx. 36 x 25 x 55cm | 50L | Coated Oxford fabric and aluminium handles | Lightweight carrying and fold-flat storage |
Amazon’s Caroeas listing also presents a smaller set of dimensions in its technical table, so treat its published measurements as approximate and check the selected variant before ordering. More generally, retailers can swap the order of length and width: focus on the shortest floor dimension, not the first number in the list.
What makes a laundry basket genuinely slim?
A narrow footprint that matches the gap
For this guide, a slim basket needs a narrow side of roughly 25cm or less. That separates a genuinely narrow hamper from a standard rectangular basket that happens to be taller than it is wide. The SpaceAid and HAIXIN are close to 20cm wide, making them the strongest choices for a tight strip beside an appliance or bathroom unit.
Measure the gap at floor level, halfway up and at the top. Skirting boards, pipes and furniture handles can make the usable space smaller than it first appears. Leave a little clearance so fabric does not scuff against a wall and a rigid basket can roll out without catching.
Enough room above the lid
A tall hamper saves floor space by stacking capacity vertically, but it still needs to open. Check worktops, shelving and radiators before buying. A 70cm-high basket beneath a low counter may fit physically yet be frustrating to load if the lid cannot lift fully.
A practical way to reach the washing machine
The best carrying method depends on the route. A removable liner is useful when the basket stays wedged in a gap: lift out the bag and leave the outer hamper in place. Wheels help on smooth, level floors but do little for stairs. Large outer handles are simplest when the basket itself is light and emptied frequently.
1. SpaceAid 65L Slim Laundry Hamper — best overall

The SpaceAid makes the strongest case for most narrow spaces because its published footprint is 40.6 x 20.3cm. That 20.3cm narrow side is the smallest in this comparison, yet the basket still provides a stated 65-litre capacity by rising to 71.1cm high.
Four detachable rods, a bamboo frame and a density-board base help the fabric body remain upright. That matters when a basket is squeezed beside a wardrobe or appliance: a completely soft bag can slump into the walkway as it fills. The flip-top lid keeps the laundry visually contained, while the bamboo side handles give you a defined place to grip it.
The main compromise is the single fixed compartment. There is no removable liner in the selected Amazon listing, so the entire hamper must come out of its gap when you want to carry the load. The coated fabric is described as water resistant, but it is not the same as a ventilated hard-plastic basket; air damp towels before dropping them inside.
Best for: a 21cm-wide gap where maximum capacity and a tidy lidded appearance matter more than a removable inner bag.
2. efluky 63L Slim Laundry Basket — best with removable liner

The efluky is only slightly wider at a published 22cm, but its removable washable inner bag changes the daily routine. Instead of pulling the whole 70cm-tall hamper away from the wall, you can lift out the liner and take the washing to the machine. That is particularly useful when the basket lives under the edge of a worktop or in a tight bedroom corner.
The 63-litre body uses support rods and bamboo elements to create an upright rectangular form. It also has a lid, so it works as a permanent dirty-laundry hamper rather than looking like a temporary carry bag. When it is not needed, the outer basket can be collapsed for storage or travel.
Like many fabric hampers, it is better suited to clothes and dry household linen than to consistently wet towels. The tall, narrow opening also makes a 63-litre claim feel different from the same capacity in a wide basket: items at the bottom are less accessible until the liner is lifted out.
Best for: flats where the hamper remains in position and you want to carry a removable bag to the washing machine.
3. HAIXIN 50L Wheeled Slim Laundry Basket — best wheeled basket

The HAIXIN is the practical alternative to a fabric hamper. Its rigid plastic body measures 41.4 x 21.4 x 62cm, so it is almost as narrow as the SpaceAid but shorter and lower in capacity at 50 litres. A pull handle and four wheels turn it into a small laundry cart, with brakes to help keep it in position.
That design makes sense when the basket travels along a hard, level floor from bedroom or bathroom to the washing machine. You do not need to lift the full 50-litre load, and the rigid walls will not bulge into the passage. Plastic is also easier to wipe down than coated fabric.
Wheels are not an advantage on stairs, deep-pile carpet or a route with thresholds. The selected listing also calls out the lack of air vents and suggests lifting the lid when necessary. Treat that as an important limitation: this is a good dry-laundry container, not somewhere to seal damp towels for several days.
Best for: single-level homes where rolling a narrow basket is easier than carrying a tall fabric hamper.
4. Caroeas 50L Collapsible Laundry Basket — best budget fold-flat basket

The Caroeas is the simplest model here: an open 50-litre fabric basket with a reinforced top rim and aluminium handles. The listing gives approximate dimensions of 36 x 25 x 55cm, making it wider than the lidded picks but still narrow enough for many bedroom, dormitory and utility-room corners.
Its advantage is portability. The aluminium handles have padded grips, the basket itself is light and the body folds flat when empty. That makes it a better choice for carrying washing to a shared laundry room, laundrette or drying area than for becoming a permanent piece of furniture.
It is less convincing if your priority is hiding dirty laundry. There is no lid or removable liner, and the coated Oxford fabric should be wiped rather than machine washed. Amazon also shows conflicting dimension sets for the selected variant, so measure with a little tolerance and re-check the detail page before buying.
Best for: lighter loads, shared laundry facilities and anyone who wants a basket that can fold away between uses.
Which style suits your narrow space?
Choose a structured fabric hamper for maximum litres
The SpaceAid and efluky use height efficiently and have lids, so they suit a bedroom, bathroom corner or visible utility area. Choose the SpaceAid for the narrowest gap. Choose the efluky when a removable liner will save you from moving the outer basket every wash day.
Choose rigid plastic for wheels and easy wiping
The HAIXIN is more expensive and holds less, but it is the easiest to roll and wipe clean. It works best when the whole trip to the machine is across a smooth floor. If your route includes stairs, a removable fabric liner is safer and more useful than wheels.
Choose an open fold-flat basket for carrying
The Caroeas is closer to a laundry carrier than a concealed hamper. It is the right shape for a room where the basket is emptied frequently or stored flat. If dirty clothes accumulate in a visible bedroom corner, a lidded model will look tidier.
How to measure before you buy
Start with the width at the floor, accounting for skirting boards and pipes. Then check the full depth so the basket does not protrude into a doorway. Finally, measure vertical clearance with the lid open rather than closed.
Masking tape is useful for marking the footprint. Walk past it, open nearby doors and pull out drawers. If the basket has wheels, make sure there is enough space in front to turn or roll it out. A model that technically fits but cannot be removed easily will make every wash day harder.
If you are comparing other compact formats too, our guide to the best laundry baskets for small spaces includes sorting and fold-flat options that are not all genuinely narrow.
Keep stored laundry from smelling musty
A lid hides laundry; it does not make damp fabric safe to store. Let bath towels, dishcloths and gym kit air before putting them in a closed hamper. Wipe the basket or liner according to the manufacturer’s instructions and leave it open to dry completely after cleaning.
In a small flat, laundry storage and drying often share the same limited room. Our guide to drying clothes in a flat without a tumble dryer covers ventilation and moisture control, while the best sock and underwear drying hangers can free up rail space for larger garments.
Our final recommendation
For most narrow spaces, buy the SpaceAid 65L Slim Laundry Hamper. Its 20.3cm width is the best fit here, and the lid, 65-litre capacity and reinforced structure make it practical as an everyday dirty-laundry bin.
Choose the efluky 63L if you want to remove and wash the inner bag. Pick the HAIXIN 50L when wheels and wipe-clean plastic are worth the higher price. The Caroeas 50L is the better budget choice when you mainly need a light basket for carrying laundry and want it to fold away afterwards.
