Rank #9 in Best Metal Garden Sheds 2026: 10 Ranked, Specs Fact-Checked
SUPEER 4 x 3 Metal Outdoor Storage Shed (1.11 m2)
Price and rating as shown on Amazon when we collected them. Both change.
The SUPEER metal outdoor storage shed is the smallest unit in this guide: a 4 ft x 3 ft steel box in black, priced at £152.15 and rated 4.4 out of 5 from 88 ratings. It takes the number 9 slot. In a category where the spec sheet usually contradicts the advert, this one mostly doesn't. The bullet gives H185 x W125.5 x D88.5 cm, and that footprint comes to about 11.96 square feet — which is what the spec sheet's "12 Square Feet" floor area claims, and what a 4 x 3 ft shed ought to measure.
What doesn't line up is the door. The spec sheet lists a door 125.5 cm wide and 185 cm high, the same width and height as the shed itself, so the "door" is dimensioned as the entire front elevation. The listing also states 88 ratings, while its own star breakdown adds up to 100 (67 five-star, 13 four-star, 14 three-star, 3 two-star, 3 one-star). Everything on this page comes from the Amazon listing, not from any test we have run.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“It certainly looks &feels like a solid garage for a robot mower. Took a little bit of time to sort out the structure, had to disassemble & reassemble the basic structure a few times. Once that was satisfactorily rectified the rest was a breeze.”
Verified purchase“Bought this for my Luba 2 mini. It's miles too big so I'd guess bigger models would suit. It's put together like a real garage. Panels, screws, frame, took two of us about 60-90 mins but it's well worth the effort. Definitely use a drill or your hands will be in bits after it.We've had it for a few months now and it's been through storms and all sorts and it's working fine. Definitely a better option than the crappy one that comes with the mammoth.As you can see in the photo, the docking station is dwarfed by this thing.”

Questions people ask
What size is the SUPEER 4x3 metal shed?
The bullet lists H185 x W125.5 x D88.5 cm, and the spec sheet states a floor area of 12 square feet.
Does the 12 square feet floor area match the listed dimensions?
Yes. 125.5 cm by 88.5 cm works out at roughly 11.96 square feet, and 4 ft by 3 ft is 12, so the bullet and the spec sheet agree here.
How big is the door on the SUPEER shed?
The spec sheet gives a door 125.5 cm wide and 185 cm high — the same figures as the shed's overall width and height, so the door is dimensioned as the whole front of the unit.
Does the SUPEER shed need assembling?
Yes. The spec sheet lists assembly as required, and the shed is supplied as one item of flat-packed panels.
What is the SUPEER 4x3 shed made of?
Metal throughout: the spec sheet lists metal for the material, base and top, alloy steel for the frame, and the bullet describes an electro-galvanised steel process with paint treatment. Water resistance is listed as water resistant.
Why does the rating breakdown not add up to 88?
The listing states 88 ratings, but the star histogram adds to 100: 67 five-star, 13 four-star, 14 three-star, 3 two-star and 3 one-star. We can only report both numbers as they appear.
