Best plastic garden shed
Updated: 22 October 2026
The bin store on the patio and the walk-in at the end of the garden answer different jobs, and amazon.co.uk still files both under one search. If you want the best plastic garden shed from this set of eight, the useful answer is who each listing is for, and who should leave it. Stars on 11 reviews are not the same evidence as 15,025. Prices and sizes are on the [plastic garden shed comparison](/hub/garden-supplies/garden-shed-plastic). Peter F. read those amazon.co.uk listings, with no laboratory test.

Best for a patio box
The only heavily reviewed resin box here is the Keter Store It Out Nova at about £137.99, listed at 880 litres, with 4.4 from 15,025 amazon.co.uk reviews. Outside it is 132 x 71.5 x 113.5 cm, and inside it is 122 x 61 x 108.8 cm. The bullets claim two 120 litre bins, shelves are not included, and the page says lockable without listing a padlock. It is the strongest evidence for a reach-in store, and a poor choice if the lock must be in the carton or if you need to stand beside the mower. The order of questions, before a model, sits in the plastic garden shed buying guide.
When the padlock or the colour decides it
Olsen & Smith, about £109.98, includes a 4-digit combination padlock, which a UK review found in the carton. The star line is 3.6 from 80 reviews, far thinner than the Keter. The bullets give 116 x 71 x 112.5 cm and the specification line gives 70.9 x 115.8 x 109 cm, so measure against both. Duramax StoreAway 850 L, about £147.37, is the dark brown box, 130 x 74 x 110 cm, at 4.1 from 2,685 reviews. Reviews describe rain at the back panel and a lid that gaps, and one UK reviewer cut the floor for a 240 litre bin. Treat water resistant as a claim.
When a walk-in is the point
A walk-in earns the money when you will stand in the store. The LARBANKE 4x6, about £339.99, lists 173 x 131 x 200 cm, a floor of 2.26 m², a ramp, and a door of 61 x 164 cm. The 61 cm door still stops a wide deck, and the padlock is not included. Buyers say the build takes longer than a 2 to 4 hour claim, and an unlevel base stopped the panels lining up. The order of that build is on how to assemble a plastic shed. The 4x6 and the 4x3 share one 3.9 from 13 reviews. Do not count that sample twice. The 4x3 suits a side return about 94 cm deep if you bring a padlock. The 8x6 at about £509.00 has 2.8 from 11 reviews. One UK review measured about 5 ft 7 in inside, with a bike wheel out of the door. Eleven reviews are not a reason to call it the best plastic garden shed.
What not to call the best shed
The Outsunny, about £71.99, is a plastic cover on a galvanised steel frame, about 12.5 kg, with a roll-up door and no floor. It has 4.4 from 202 reviews, and several people use it for a mobility scooter. A zip that fails within weeks, and a hem that will not fix to the frame, are the faults that recur. It is the wrong answer if you wanted a rigid store. Keter’s Darwin and Stronghold walk-ins are not in this set, so do not copy a snow-load figure onto a LARBANKE. None of these files shows a Sold Secure mark.
Common questions
Which listing has the strongest review evidence?
The Keter Store It Out Nova, at about £137.99, has 4.4 from 15,025 amazon.co.uk reviews. Duramax is next among the boxes, at 4.1 from 2,685, and Olsen is 3.6 from 80. The walk-ins sit on 13 shared reviews, 11 reviews, or 7 reviews. A large count is still not a laboratory test of waterproofing, and the Keter remains a reach-in box rather than a shed you stand in.
Which box includes a padlock?
Olsen & Smith, at about £109.98, supplies a 4-digit combination padlock, and a UK review confirms it is in the box. Keter says lockable and does not list a padlock. The LARBANKE 4x3 and 4x6 say the padlock is not supplied. Buy the Olsen when the lock must arrive with the carton, and check both of its size lines before you clear a space on the patio.
Should I buy an 8x6 with 11 reviews?
Not as a best pick. LARBANKE B0H4FDQTJR is about £509.00 with 2.8 from 11 reviews, and one UK review measured about 5 ft 7 in inside with a bike wheel out of the door. The sister listing at about £509.99 has 2.9 from 7 reviews. The floor is listed at 4.08 m² and the shell at 83.7 kg, so you are paying for a large build on a thin sample. Measure the inside, and do not treat the foot label as the tape.
Is the Outsunny a best plastic shed?
No. At about £71.99 it is a cover on a steel frame, 12.5 kg, with 4.4 from 202 reviews, and it has no resin floor. People use it for a mobility scooter. Zips, the hem, and wind are the limits, and the page suggests a wall for better resistance. Call it a temporary shelter. A rigid box or walk-in is a different product.
What if I need a bike inside?
A bike is a poor fit for the patio boxes. The Keter’s internal depth is 61 cm, and the 4x6 door is also 61 cm wide. On the 8x6 at about £509.00, a UK review still had a bike wheel sticking out of the door after measuring about 5 ft 7 in inside. Tape the wheelbase and the handlebars, then compare that with the door, not with the 8x6 title.
Who should skip plastic and look at wood?
Skip the resin listings when you want a door you can repair in timber, a heavier shell, or a security claim these amazon.co.uk files do not make. A hasp is not a rating. The plastic case in this set is the opposite: no paint schedule, a Keter box with a large review count, or a walk-in only after you accept a thin sample.
