Best plastic tool shed
Updated: October 2026
The best plastic tool shed here is the Keter Store It Out Nova for most buyers. That is a conditional top pick based on its specifications, price and amazon.co.uk review record, not a laboratory verdict. The [plastic tool shed comparison](/hub/tool-accessories/tool-shed-plastic) shows all four products. This guide explains why the Nova leads, when cheaper Olsen & Smith boxes make sense and why the Duramax price does not guarantee a better result. None is a walk-in workshop or secure locker. A qualifying purchase can earn a commission at no extra cost to you.

What best can mean in this set
All four products use plastic or resin, provide doors and a lid, and claim 775–880 litres. Compare usable dimensions, review evidence, lock claims and price. A larger litre figure does not prove that a wall is stiffer, while a waterproof bullet does not cancel reports of rain entering. There has been no Products Compared lab test of these stores. Best means the strongest purchase case among these four at the captured information.
Which? describes light plastic sheds as difficult to secure, and these products weigh only about 17–22 kg empty. If you would be seriously affected by losing the contents, choose a more substantial store. The plastic versus wooden shed guide explores that trade-off.
Why the Nova is the default pick
The Keter Store It Out Nova claims 880 litres, with external dimensions of 132 × 71.5 × 113.5 cm and internal dimensions of 122 × 61 × 108.8 cm. It has twin doors, a lift-up lid and a floor with shelf supports. The title states a five-year warranty. Shelves are not included, and lockable does not mean a padlock is supplied. Its 4.4-star average from 15,025 amazon.co.uk ratings is higher and based on far more feedback than the alternatives here. Reviewers often manage assembly in about an hour, although awkward stages benefit from a second person.
Fit remains the reason to skip it. The 61 cm internal depth is plausible for two typical 120 litre bins, as named in the listing, but not for a 240 litre council bin around 73–74 cm deep. It will not take most adult bikes lengthways either. Use the Nova for hand tools, a compact mower or bins you have measured, rather than treating 880 litres as permission to guess.
When an Olsen box is the rational cheaper buy
Olsen & Smith appears twice because these are separate ASINs, not one review pool. B0DWSKMVZ7 was £109.98 with 3.6 stars from 80 ratings; B0CNH56LQL was £119.99 with the same 3.6 average from 354 ratings. Both claim 775 litres, two 180 litre slimline bins, a gas-assisted lid and an included combination padlock. The cheaper listing is the best value only if you accept its limitations.
The recurring concern is flexible or thin panels, and one listing also gives conflicting dimensions, so confirm the current measurements. Two 180 litre slimline bins does not promise room for two 240 litre council bins. Reviews on both Olsen listings include buyers whose bins did not fit, and one B0CNH56LQL buyer reports that the padlock was missing. Measure first, then use the plastic wheelie bin store guide to compare the footprints.
Why the dearest box is not automatically the pick
The Duramax StoreAway claimed 850 litres and cost £147.37 in the captured comparison, making it dearer than the Nova at that point. Its 4.1-star average from 2,685 ratings is credible evidence, and the heavy-duty floor, sloped threshold, doors and lifting roof are practical features. The title names two 120 litre bins, but no internal measurements are stated.
Price alone does not overcome its review pattern. UK reviewers mention rain collecting in a channel beneath the rear panel, despite the listing’s water-resistant and drain language. One reviewer also says a 240 litre bin did not fit. A lock is not stated as included. Choose it if its 130 × 74 × 110 cm external footprint or access arrangement specifically suits your site and measured contents. Otherwise, the Nova offers the stronger overall case. Before either arrives, the assembly guide explains why level slabs and anchoring matter to a box this light.
Common questions
Is the Keter Nova a laboratory winner?
No. It is the conditional top pick within this four-product comparison, based on listing data and its 4.4-star average from 15,025 amazon.co.uk ratings. Products Compared did not conduct a lab test. The recommendation still depends on the 61 cm internal depth suiting your measured contents.
When is the cheaper Olsen enough?
It can be enough for low-value, light garden items on a flat and sheltered base. The £109.98 listing offers useful access and claims an included combination padlock. Accept the 3.6-star average, thin-panel review theme and dimensional uncertainty before choosing price over the Nova’s stronger record.
Are the two Olsen listings the same product?
They share a 775 litre claim and many listed features, but they are different ASINs with different prices and review counts. Do not merge their ratings. One had 80 ratings and the other 354 at capture, although both averaged 3.6 stars.
Is the Duramax better because it cost more?
Not on price alone. It has a respectable 4.1-star average and practical access, but UK reviews report water collecting in the rear channel, and no included lock is stated. Buy it for a specific fit or feature, not because £147.37 automatically signals higher quality.
Can any of these hold two 240 litre bins?
The listings do not promise that. Keter and Duramax name two 120 litre bins, while Olsen names two 180 litre slimline bins. A typical 240 litre bin is around 73–74 cm deep, already exceeding the Nova’s 61 cm internal depth. Measure your own bins.
What should I avoid storing in the top pick?
Do not treat the Nova as a safe for expensive power tools, and never store petrol or gas cylinders in it. Water-resistant construction is not sealed storage. Use closed tubs for moisture-sensitive items and select stronger security if theft would cause serious loss.
