The best plastic garden sheds, compared.
Top pick: Keter Store It Out Nova – Highest score: internal 122 × 61 × 108.8 cm, about £137.99, and 4.4 from 15,025 reviews, with a bin that a review says fits. Best value: Outsunny 1.2 x 1.8 m shed tent – Highest value-part score among the rest: about £71.99, 4.4 from 202 reviews, as a cover on a frame rather than a resin shell. Updated October 2026.
A plastic garden shed is a rigid resin or polypropylene store for a UK garden: a reach-in box about a metre high, or a walk-in shell with a floor panel. You buy one to keep bins, a mower, tools or bikes dry without a timber paint schedule. A plastic cover on a steel frame is a temporary shelter. Judge it by internal centimetres, including handles, not by a foot label such as 8×6. The door has to take the widest item, and a hasp has to take a padlock. An integrated plastic floor is not a foundation. An unlevel base is why panels fail to line up, so the shell needs a flat, drained platform. Waterproof on the listing is a claim, not a test. In England, within 2 m of a boundary, overall height is capped at 2.5 m, and the shed must not stand in front of the principal elevation. Scotland, Wales and Northern Ireland differ. These shells are incidental storage, not sleeping and not fuel. Size, lock and base are in the [plastic garden shed buying guide](/hub/garden-supplies/garden-shed-plastic/sub/garden-shed-plastic-buying-guide).

Personal buying guide
Question 1 of 2
What are you storing?
The Keter Store It Out Nova, model 249317, is a resin box at about £137.99, external 132 × 71.5 × 113.5 cm and internal 122 × 61 × 108.8 cm, at 21.6 kg. The listing claims 880 litres and also prints 880 kg on that capacity line, so the kilogram figure is a second printed number, not a load this file has weighed. It carries 4.4 from 15,025 amazon.co.uk reviews, the only large sample among the resin boxes in this set. The bullets say two 120 litre wheelie bins, a reviewer says two bins fit, and shelves are not included. Buyers describe a dry box and a build one person can manage, and they also describe a confusing booklet, a screw that does not match, a lid gap, and a cracked base found after assembly. The page says the doors and lid are lockable and does not list a padlock. Side vents turn up in a review, not as a measured airflow figure. It is the top pick on score, not on a waterproof trial.
Pros
Cons
Best for: You want a resin box for 120 litre bins, and you will check the base after the build.
Less suitable: You need a padlock in the box, shelves included, or a walk-in you can stand in.
Specifications
Common questions
Will two 120 litre bins fit?
The bullets say two 120 L wheelie bins. Internal size is 122 × 61 × 108.8 cm. A reviewer says two bins fit. Measure your own bins.
Is a padlock in the box?
The page says lockable and opens from the top or the front. It does not say a padlock is included. Shelves are not included.
What faults come up in UK reviews?
Buyers praise a dry box and a manageable solo build. Repeated complaints are a confusing booklet, a screw that does not match, a lid gap, and a cracked base found after assembly.
The Outsunny 84H-139V00CG is a plastic cover on a galvanised steel frame, listed at 179 × 120 × 165 cm and 12.5 kg, priced at about £71.99. The door is a 126 × 106 cm roll-up, and the box lists six ground stakes, six expansion screws and 15 bungee cords. There is no floor panel. The page calls the cover water resistant and tells you to place the shelter against a wall for better wind resistance. Across 202 amazon.co.uk reviews the line is 4.4, and several people use it for a mobility scooter and find the frame up quickly. A zip that fails within weeks, and a cover hem that will not fix to the frame, are the faults that recur. The listed floor area of 2.15 m² is the ground the cover stands over, not a deck you can walk, and 165 cm of height is low if you expected to stand inside a resin shed. It is best value on the value part of the score, not because it is a resin shell.
Pros
Cons
Best for: You want a light cover for a mobility scooter or similar kit, and you can stake it against a wall.
Less suitable: You need a resin walk-in, a floor panel, or a zip you can treat as a lock.
Specifications
Common questions
Is this a resin shed?
No. The listing is a plastic cover on a galvanised steel frame, 12.5 kg, sold as a shed tent. It is not a double-wall resin shell.
What is included to hold it down?
Six ground stakes, six expansion screws, and 15 bungee cords. The bullets say to place it against a wall for better wind resistance.
What do UK reviews say about the door?
Several reviews use it for a mobility scooter and find assembly quick. Others report a zip failing within weeks, or a cover hem that will not fix to the frame.
The Duramax StoreAway 850 L, model 86621, is a dark brown polypropylene box, 130 × 74 × 110 cm and 18.6 kg, at about £147.37. The attribute says water resistant, and the page claims 850 litres. The star line is 4.1 from 2,685 amazon.co.uk reviews. The bullets name 120 litre bins. One UK reviewer could not fit 240 litre bins and cut the floor, and another fitted one bin plus folding furniture. Reviews describe rain at the back panel and a lid that gaps, especially after the box is moved. Reviewers also report undrilled holes and a cordless drill, which the sales bullets do not mention. A lock is not stated, and the floor line is a sloped threshold rather than a separate ramp in the box.
Pros
Cons
Best for: You want a dark brown box for 120 litre bins, and you can drill the holes the reviews mention.
Less suitable: You need a 240 litre bin to go in uncut, or a listing that states a lock.
Specifications
Common questions
Does it fit a 240 litre bin?
The bullets name 120 litre bins. One UK reviewer could not fit 240 litre bins and cut the floor. Another fitted one bin plus folding furniture.
Is it watertight?
The attribute says water resistant. Reviews describe rain at the back panel and a lid that gaps, especially after the box is moved. That is not a test result.
Do you need a drill?
The sales bullets do not say so. Reviewers report undrilled holes and a cordless drill. Assembly is required.
The LARBANKE 4×6, model 4*6FT, is listed at 173 × 131 × 200 cm, with a claimed floor of 2.26 m² and a claimed volume of 4.5 m³, at about £339.99. The door is 61 cm wide and 164 cm high. The bullets say an integrated floor panel, a low-profile ramp, vents, a side window, and a 12 mm double wall. That 12 mm line is a sentence on the page, not a thickness measured for this comparison. The padlock is not included. The 3.9 from 13 reviews is the same line and overlapping text as the narrower 4×3 listing, so these are not 13 reviews of this footprint alone. Buyers in that shared text say the build takes longer than a 2–4 hour claim, one experienced buyer took two days, and an unlevel base stopped the panels lining up. Item weight is not in the file.
Pros
Cons
Best for: You want the smaller walk-in with a ramp in the bullets, and you can give the build more than an afternoon.
Less suitable: You need a review file that is only this listing, or a door wider than 61 cm.
Specifications
Common questions
Does the 4×6 include a floor and a ramp?
The bullets say an integrated floor panel and a low-profile ramp. Item weight is not in the file. The floor panel is not a foundation.
How long does assembly take?
Buyers in the shared review text say longer than a 2–4 hour claim. One experienced buyer took two days. An unlevel base stopped panels lining up.
Is the padlock included?
No. The bullets say the single door is lockable and the padlock is not included.
The LARBANKE 4×3, model 4*3FT, is a narrow polypropylene walk-in listed at 94 × 127 × 196 cm with a floor of 1.18 m², at about £339.99. The hinged door is 61 cm wide and 163 cm high. The bullets say a steel hasp takes a padlock, and that the padlock is not supplied. The star line is 3.9 from 13 reviews, and that text matches the 4×6 file, including the same best-seller rank, so these are not 13 reviews of this footprint alone. Item weight is not in the file. The page says waterproof and lists vents and a side panel, which are sentences on the listing. A 500 kg figure is printed beside the floor area. The 61 cm door is the opening you have to measure against a mower or a bin before you treat the 1.18 m² floor as usable standing storage.
Pros
Cons
Best for: You have a side return about 94 cm deep, and you will buy your own padlock.
Less suitable: You need an independent review sample, a stated weight, or a door wider than 61 cm.
Specifications
Common questions
Is a padlock included?
No. The bullets say a steel hasp accepts a padlock and that the padlock is not supplied. A hasp is not a security rating.
Can you treat the 13 reviews as this shed only?
The star line is 3.9 from 13, and the review text matches the 4×6 file, including the same best-seller rank. Do not treat it as a separate sample.
How wide is the door?
61 cm wide and 163 cm high. The footprint on the spec line is 94 × 127 × 196 cm.
The Olsen & Smith store is a polypropylene box listed at 775 litres and 17.8 kg, at about £109.98, with a 4-digit combination padlock that a UK review confirms is in the box. The star line is 3.6 from 80 amazon.co.uk reviews. The bullets give 116 × 71 × 112.5 cm, while the specification line gives 70.9 × 115.8 × 109 cm, so the two size lines in this file do not agree. Twin doors and a gas-assisted lid are claimed. Several reviewers call the sides and back thin or flimsy before the screws go in, then acceptable once the box is built. One buyer says the panels are under 1 mm and do not click together. The page says waterproof, which is a listing claim, not a result from a test in this file.
Pros
Cons
Best for: You want a reach-in box with a padlock supplied, and you will measure the space against both size lines.
Less suitable: You need one agreed centimetre size, or panels the reviews do not call thin before assembly.
Specifications
Common questions
Does the listing include a padlock?
Yes. The bullets say a 4-digit combination padlock is supplied, and a UK review confirms a padlock in the box.
Which size line should you trust?
The bullets say 116 × 71 × 112.5 cm. The specification line says 70.9 × 115.8 × 109 cm. Both are in the file, and they conflict. Measure the space against both.
How do reviewers describe the panels?
Several call the sides and back thin or flimsy before the screws go in, then acceptable once built. One buyer says the panels are under 1 mm and do not click together.
The LARBANKE 8×6 with a ramp in the title uses the same 1.7 × 2.4 × 2.3 m and 83.7 kg lines as the other 8×6 listing, at about £509.99. The listing claims a floor, a window, a vent and a ramp, and it prints 318.90 cubic feet beside a floor of 4.08 m². The door-style field says sliding doors, 128 × 180 cm, while the other 8×6 file says bi-fold. The star line is 2.9 from 7 amazon.co.uk reviews. Four UK texts cover too many screws and rain damage, a hard build that was acceptable once the shell was up, roof instructions the buyer chose to ignore, and one short positive note. Delivery came in three vans, and the bullets say three packages may arrive on different days, with a stated 3–5 hours for 2–4 people. A stainless lock is claimed on the page. The two URLs share a part family, so they are not two unrelated sheds.
Pros
Cons
Best for: You want the 8×6 title that names a ramp, and you can wait for three packages.
Less suitable: You need a large independent review sample, or a door style that matches the other 8×6 file.
Specifications
Common questions
Does the listing include a ramp?
The title includes a ramp, plus floor, window, and vent. The door-style field says sliding doors, 128 × 180 cm.
What do the few UK reviews say?
Four texts: too many screws and rain damage; hard to build then acceptable once up; roof instructions the buyer ignored; one short positive. Delivery came in three vans.
How long does the listing say it takes?
The bullets say 3–5 hours for 2–4 people, and that three packages may arrive on different days. Wait for every carton before you build.
The LARBANKE 8×6, listed as the 8×6 Garden Shed, is 1.7 × 2.4 × 2.3 m and 83.7 kg on the spec line, with a floor of 4.08 m² and a door of 128 × 180 cm, at about £509.00. The star line is 2.8 from 11 amazon.co.uk reviews. One UK review says the inside is 5 ft 7 in and a bike wheel sticks out of the door, so the 8×6 foot label and the 1.7 × 2.4 × 2.3 m line are not the same measurement as that owner took. Reviewers describe a long build, a weak booklet, more than 100 pieces, a slightly damaged side, and one paid fitter. The bullets recommend 2–3 people, and the door-style field says bi-fold. It shares a part family and the 83.7 kg line with the other 8×6 listing at about £509.99. The page says waterproof, and a window and dual vents are claimed. At 2.3 m outside, a site within 2 m of a boundary in England sits close to the 2.5 m overall cap, which is a planning limit rather than a strength test of this shell.
Pros
Cons
Best for: You have help for a large resin shell, and you will measure the inside before a bike goes in.
Less suitable: You need the foot label to match a reviewer’s tape, or a short build from the booklet.
Specifications
Common questions
Is the inside actually 6 ft?
One UK review says the inside is 5 ft 7 in and a bike wheel sticks out of the door. The spec line is 1.7 × 2.4 × 2.3 m. Measure before a bike goes in.
How was assembly described?
Reviewers cite a long build, a weak booklet, more than 100 pieces, a slightly damaged side, and one paid fitter. The bullets recommend 2–3 people.
How does this differ from the other 8×6 listing?
The other 8×6 is about £509.99, 2.9 from 7 reviews, and its door-style field says sliding. Both list 83.7 kg and the same part family.
Eight amazon.co.uk listings were scored from the shelf prices, star lines and UK review notes already on those pages. There is no laboratory test. A bullet that says waterproof, water resistant or a wall thickness is a listing sentence, not a measured result. The score is four parts that add to 100. The highest score is the top pick, once. The highest value-part score that is not that top pick is best value, once. Planning Portal, the statute and the nation guides explain siting. They are not a score for any listing.
Stars
40%The amazon.co.uk star rating divided by 5, then multiplied by 40, and rounded to the nearest integer. A 4.4 becomes 35. A 2.8 becomes 22.
Review sample
25%200 or more reviews score 20. From 50 to 199 scores 12. From 10 to 49 scores 6. From 1 to 9 scores 2. Two walk-in files share one 3.9 from 13 and overlapping text, so each is scored as a 1–9 pool, not as two separate samples of 13.
Fit as storage
25%Internal centimetres, a floor or a stated door, and whether reviews describe a bin that fits or a measured shortfall. A resin box with a large review file scores higher than a cover with no floor, or a large shell whose inside a review measured short of the foot label.
Value
10%Shelf price in GBP against what the listing actually is. The lowest price in the set is a cover, not a resin shell, and that is the highest value-part score among products that are not the top pick. A high price on a thin review file scores lower.
Choose the job before the foot label. A box holds bins and a mower you lift. A walk-in is for standing storage. A plastic cover on a frame is a temporary shelter. Stars do not replace internal centimetres, a lock you can see in the box, or a base that is actually level. Waterproof on the page is a claim. The eight rows are amazon.co.uk listings. None of the scores is a laboratory test.
A plastic garden shed is a rigid resin or polypropylene store. On UK listings the usual shapes are a reach-in box about 1.1 m high, or a walk-in shell with a floor panel. People buy one for bins, a mower, tools or bikes, and they skip a timber paint schedule. A plastic cover stretched over a steel frame is a temporary shelter. It is not the same product as a moulded box, even when the title says shed. What must fit is a centimetre question, including handles.
8×6 and 4×6 are nominal. Measure what must fit, including handles and the door width. One UK review of a large walk-in measured about 5 ft 7 in inside, and a bike wheel stuck out of the door. A 61 cm door will not pass every mower you already own.
An integrated plastic floor is not a foundation. Reviews blame an unlevel base for panels that will not line up. Put the shell on a flat, drained platform. A slab on a slope is a builder’s job, and that cost is not in the shelf price.
Attributes say waterproof or water resistant. Reviews on one box describe rain at the back panel and a lid gap. A wall-thickness sentence is not a measurement. A hasp is not a security rating, and a padlock is included only when the listing says so.
Start with the object, in centimetres, including handles. A foot label such as 8×6 is a name, not an internal tape. In this set one UK review of the large walk-in measured about 5 ft 7 in inside, and a bike wheel stuck out of the door. The resin boxes print external lines around 130 cm wide and about 110 cm high. Where an internal line exists, use that. The Keter box prints internal 122 × 61 × 108.8 cm, and a reviewer says two bins fit. The Duramax bullets name 120 litre bins.
The floor panel is the bottom of the product. It is not a foundation. Reviews of the walk-ins say an unlevel base stopped the panels lining up. Site the shell on a flat, drained platform, and do not start until every carton has arrived. One 8×6 listing says three packages may arrive on different days. Read the lock line as supplied. The Olsen box includes a 4-digit combination padlock, and a UK review confirms it is in the carton. The Keter page says lockable and does not list a padlock.
Three typical situations, each with a recommendation from this comparison.
You need a measured opening for bins, not a bins bullet on its own. The Keter Store It Out Nova is a resin box at about £137.99, internal 122 × 61 × 108.8 cm, with 4.4 from 15,025 reviews. A reviewer says two bins fit. A padlock is not listed, and reviews include a lid gap and a cracked base.
You need a walk-in footprint you can stand in, and you will buy your own padlock. The LARBANKE 4×6 is listed at 173 × 131 × 200 cm and about £339.99, with a floor and a ramp claimed and a door 61 cm wide. The 3.9 from 13 reviews overlaps the narrower 4×3 file. Item weight is not stated.
You want a light cover you can move, and you can site it against a wall. The Outsunny tent is a plastic cover on a galvanised steel frame at about £71.99, 12.5 kg, with 4.4 from 202 reviews. There is no floor. Reviews cite a zip that fails and a hem that will not fix to the frame.
The top pick is the Keter Store It Out Nova at about £137.99. It scores 84: 4.4 from 15,025 amazon.co.uk reviews, internal size 122 × 61 × 108.8 cm, and a reviewer says two bins fit. Reviews also describe a lid gap, a cracked base after assembly, and a padlock that is not listed. The best value is the Outsunny shed tent at about £71.99. Its value part is the highest among the products that are not the top pick. It is 4.4 from 202 reviews, a plastic cover on a steel frame with no floor, not a resin shell. The Duramax box scores 75 overall, ahead of the tent on the total, and it is not best value: rain at the back panel is in the reviews, and its value part is lower.
Keter Store It Out Nova
Highest score: internal 122 × 61 × 108.8 cm, about £137.99, and 4.4 from 15,025 reviews, with a bin that a review says fits.
Outsunny 1.2 x 1.8 m shed tent
Highest value-part score among the rest: about £71.99, 4.4 from 202 reviews, as a cover on a frame rather than a resin shell.
