# Best Water Butt 2026: £0.24 to £0.71 a Litre Source: https://www.ranked10.co.uk/garden/best-water-butt Published: 2026-09-11 | Updated: 2026-09-11 | Prices checked on Amazon UK on 2026-09-11 A water butt is a plastic barrel, and whether you pay £59 or £150 for 210 litres of one makes no difference to the water inside it. Across this ranking the price per litre of storage runs from £0.238 to £0.714 — a factor of three — because every listing quotes a capacity and none quotes value. The clearest pair is a 210-litre barrel at £58.99 and a 210-litre amphora at £149.95: same volume, same 210kg of water when full, and £91 of difference that buys a shape and a colour. Behind a shed, that £91 buys nothing at all. The listings do not make the comparison easy either. One butt titled 100 Litres has a capacity field reading 26 gallons, which is 118 litres — an 18 per cent disagreement on the same page. A 210-litre butt declares its weight as 1kg, and a 100-litre slimline as 2kg, neither of which is possible for a barrel with wall thickness; the one honest figure here is 7.7kg for 227 litres, from the only listing offering a five-year warranty. And a two-pack of 100-litre butts quotes the capacity of one, so the pair has to be worked out from the price. What actually decides the choice is space and the weight of the contents. A 210-litre butt weighs 210kg full and a 350-litre one weighs 350kg, so the base, the stand and the ground all have to take that load — and a stand is not decoration: it lifts the tap above a watering can, which is how gravity does the work. Slimline models are 32cm deep and fit down a side return at about 19 per cent more per litre of storage than a plain 210-litre barrel, and wide low butts are more stable but need a metre of ground. Into September, with the rain arriving, the arithmetic is simple: £0.281 a litre is the best value here with decent reviews, and £0.238 is the cheapest if you accept a listing that knows very little about its own product. ## The ranking ### 1. STORM TRADING GROUP 210 Litre Water Butt with Stand, Tap and Diverter - Price: £58.99 | Amazon rating: 4.5 from 537 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/storm-210l - Buy on Amazon: https://www.amazon.co.uk/dp/B0BLZCM4SR?tag=ranked10-21 The best value here per litre: 210 litres for £58.99, which is £0.281 a litre, with 537 ratings at 4.5 stars. The best value in this ranking by the measure that matters: 210 litres for £58.99, which is £0.281 per litre of storage, with 4.5 stars from 537 ratings — the second-deepest sample here. It is a 57 x 57 x 97cm barrel in black plastic, supplied as a kit with a stand, a tap and a diverter, and it ranks second in Amazon's water butt category. Price per litre is the number to use here, because every listing quotes a capacity and none of them quotes value. Across this ranking the same job ranges from £0.238 to £0.714 per litre, a factor of three, and the reason is design rather than size: a plain barrel holds the same water as a terracotta amphora and costs a third as much per litre. What the extra buys is how it looks and, occasionally, a longer warranty. The physics is the other thing worth knowing before choosing: 210 litres of water weighs 210kg, so the butt, its stand and the ground beneath carry a quarter of a tonne when full. This listing gives the dimensions of the stand as well as the butt, which is the sort of detail that shows the maker expects it to be positioned properly. The reviews are brief and satisfied: good item, easy to fit, does the job well, holds water. Pros: £0.281 per litre: the best value among the well-reviewed butts here; 537 ratings at 4.5 stars, 70 per cent five-star; A kit with stand, tap and diverter included; Ranked 2nd in Amazon's water butt category; Stand dimensions published, so the height can be planned Cons: 3 per cent of its 537 ratings are one-star; 210 litres weighs 210kg when full; Black plastic: it will look like a barrel; £25.49 more than the cheapest 100-litre slimline ### 2. Harcostar 227 Litre Water Butt Kit with Stand, Tap and Diverter, 5 Year Warranty - Price: £69.99 | Amazon rating: 4.4 from 323 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/harcostar-227l - Buy on Amazon: https://www.amazon.co.uk/dp/B07FPKG691?tag=ranked10-21 The only butt here with a five-year warranty, and the only listing that publishes a believable weight: 7.7kg for 227 litres. The premium option, and the only one in this ranking that offers something a cheaper barrel does not: a five-year warranty. It holds 227 litres for £69.99 — £0.308 per litre, mid-range — in a 60 x 60 x 129cm barrel in grey plastic with a stand, tap, downpipe diverter and child-safe lid in the box. It is also the only listing here that publishes a believable weight: 7.7kg empty. Two others give 1kg and 2kg for butts of 210 and 100 litres, which are the sort of figures that appear when a field is filled from a catalogue rather than measured. A 227-litre butt carries 227kg of water when full, so the empty 7.7kg is a small part of the load, but it is the number that tells you whether you can lift it into position alone. The 129cm height is the other practical figure: a butt on a 30cm stand puts the tap around knee height, above a watering can and below a hose reel, which is where the gravity flow in the reviews comes from. Buy this one for the warranty and the stated weight; buy the cheaper 210-litre barrel if neither matters. Pros: A five-year warranty: the only one in this ranking; 7.7kg published, the only believable empty weight here; A complete kit: barrel, stand, tap, diverter, child-safe lid; 227 litres at £0.308 per litre, mid-range across the ranking; 323 ratings at 4.4 stars, 68 per cent five-star Cons: 4 per cent of its 323 ratings are one-star; £69.99 against £58.99 for 17 fewer litres; 60 x 60cm footprint plus the stand; 129cm tall: check it fits where you want it ### 3. Zinc Products 227 Litre Water Butt Kit, Green with Stand and Diverter - Price: £69.99 | Amazon rating: 4.6 from 148 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/zinc-227l - Buy on Amazon: https://www.amazon.co.uk/dp/B0B94CJ23C?tag=ranked10-21 The best-rated butt in the ranking at 4.6 stars: 227 litres for £69.99, with the full kit and a child-safe lid. The best-rated water butt here: 4.6 stars from 148 ratings with 79 per cent five-star and 2 per cent one-star, the cleanest record in the ranking. It holds 227 litres for £69.99, which is £0.308 per litre, in a green barrel measuring 99 x 60 x 99cm, and it arrives as a kit with a stand, tap, diverter and child-safe lid. Its shape is why it costs what it does per litre. At 99cm long and 60cm wide it is a low, wide butt — nearly a metre across — where the cheapest 210-litre option is a 57cm square barrel. Wide butts are more stable when full and easier to hide behind a shed; the trade is floor space, and the 99cm width is the dimension to check against the gap you have. The reviews are enthusiastic and specific: easy to install, great for the back of the garden, strong and sturdy, and one buyer who bought two and reports them both full of rainwater. At £0.308 per litre it is neither the cheapest nor the dearest here — it is the one with the best record, and 148 ratings of evidence is worth more than the 59 ratings behind the 350-litre butt below it. Pros: 4.6 stars: the best rating in this ranking; Only 2 per cent one-star ratings from 148 reviews; 227 litres at £0.308 per litre, with the full kit; Low and wide at 99 x 60 x 99cm: stable when full; A child-safe lid, stand, tap and diverter included Cons: 99cm wide: it needs the floor space to match; £69.99 for 227 litres, against £58.99 for 210; Green plastic: it will look like a barrel; 148 ratings is a modest sample ### 4. STORM TRADING GROUP 100 Litre Slimline Water Butt Kit with Tap - Price: £33.50 | Amazon rating: 4.5 from 800 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/storm-100l-slim - Buy on Amazon: https://www.amazon.co.uk/dp/B0BLZ9GMHK?tag=ranked10-21 The most-reviewed butt in the ranking at 800 ratings: a 100-litre slimline for £33.50 with the full kit. The most-reviewed water butt here: 800 ratings at 4.5 stars, 69 per cent five-star and 3 per cent one-star, for £33.50. It holds 100 litres in a 36 x 32 x 95cm slimline barrel — 32cm deep, which is the point of the design — and it comes ready to use with a tap and a downpipe filler in the kit. That works out at £0.335 per litre, a little above the best 210-litre barrel here. Slimline costs money per litre and saves space. Compare it with the 210-litre barrel at £58.99: that is £0.281 per litre, so this small butt pays about 19 per cent more per litre of storage, and in exchange it takes a third of the footprint and fits down the side of a house. For a small garden or a terrace, that is the whole decision. The reviews are about the practical side: fab, easy to put together, saving my water bills, and one buyer who now waters all their plants from it. At 100 litres a full butt weighs 100kg, manageable on a patio and too much for a balcony — and it takes only about 5mm of rain on a 20-square-metre roof to fill it, which is why the reviews mention how quickly these fill. Pros: 800 ratings at 4.5 stars: the deepest sample here; 32cm deep: it fits where a round barrel cannot; £33.50 with a tap and downpipe filler in the kit; 100 litres fills with about 5mm of rain on a small roof; Ranked 3rd in Amazon's water butt category Cons: £0.335 per litre: 19 per cent above the best value here; 3 per cent of its 800 ratings are one-star; 100 litres is less than half a 227-litre barrel; A full butt still weighs 100kg ### 5. Edena 100 Litre Slim Space Saver Water Butt with Tap - Price: £33.89 | Amazon rating: 4.4 from 128 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/edena-100l-slim - Buy on Amazon: https://www.amazon.co.uk/dp/B0GV11NKL3?tag=ranked10-21 The category best seller: a 100-litre slimline whose capacity field says 26 gallons — which is 118 litres. The best seller in Amazon's water butt category, and the clearest example of this category's unit problem: the title says 100 litres and the capacity field says 26 gallons. Twenty-six imperial gallons is 118 litres, so two numbers on the same page disagree by nearly a fifth. It costs £33.89 with 4.4 stars from 128 ratings, and it is a 32 x 36 x 95cm slimline barrel in black plastic. Working out the value therefore takes a decision about which number to believe. At 100 litres it is £0.339 per litre; at 118 litres it would be £0.287, which would make it the second-best value here. The honest reading is that this is the same barrel as the 100-litre slimline below, sold under another brand with a capacity field converted carelessly, and that the seller's own bullet — collect and store up to 100 litres — is the figure to use. What the ranking does tell you is that people buy it: first place in the category against 800 ratings for the identical barrel below, which suggests ranks move faster than reviews accumulate. The reviews are short and positive: good quality water butt, slim but of a good capacity, easy to put together, does the job value for the price. Pros: Ranked 1st in Amazon's water butt category; A 32cm-deep slimline that fits a narrow space; £33.89 for a 100-litre barrel with a tap; 4.4 stars from 128 ratings, 69 per cent five-star; The title, bullet and dimensions agree on 100 litres Cons: The capacity field says 26 gallons, which is 118 litres; 6 per cent of its 128 ratings are one-star; No stand included; 128 ratings behind a first-place rank ### 6. 210 Litre Water Butt and Lid, Black - Price: £49.99 | Amazon rating: 4.2 from 104 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/generic-210l - Buy on Amazon: https://www.amazon.co.uk/dp/B0FD3RB9W2?tag=ranked10-21 The cheapest butt here per litre at £0.238 — with a weight of 1kg for 210 litres, which is impossible. The cheapest water butt in this ranking per litre: 210 litres for £49.99, which is £0.238 — 15 per cent below the next best and a third of the dearest 210-litre butt here. It carries 4.2 stars from 104 ratings with 65 per cent five-star and 4 per cent one-star, and it is a 57 x 57 x 97cm barrel with a lid, the same dimensions as the best-value butt in this ranking. Its weight is given as 1kg, which is not true of any 210-litre barrel: the Harcostar, the only listing here with a believable figure, states 7.7kg for 227 litres. A field like that comes from a catalogue rather than a scale, and it matters because the empty weight decides whether one person can move the butt into position. What is accurate here is the price and the dimensions. The listing itself is minimal — 210LT water butt and lid, with no kit described — and the reviews fill the gap: complete with tap, delivered promptly, lovely condition. If you already have a stand and a diverter, or plan to buy them separately, this is the cheapest way here to put 210 litres of storage in a garden. Pros: £0.238 per litre: the cheapest in this ranking; £49.99 for 210 litres with a lid; The same 57 x 57 x 97cm dimensions as the best-value butt here; A reviewer reports it arrives complete with a tap; 4.2 stars from 104 ratings Cons: Weight listed as 1kg, which no 210-litre barrel is; A minimal listing: no kit described; 4 per cent of its 104 ratings are one-star; Only 104 ratings, and no stand included ### 7. Hardys Slimline Water Butt 100L, Recycled Plastic with Stand and Diverter - Price: £44.99 | Amazon rating: 4.1 from 159 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/hardys-100l-slim - Buy on Amazon: https://www.amazon.co.uk/dp/B0FFHLJ8MC?tag=ranked10-21 A 100-litre slimline in recycled plastic for £44.99 — the dearest small butt here per litre, with a complete kit. The expensive option among the small butts: £44.99 for 100 litres, which is £0.45 per litre — 34 per cent more than the better-reviewed slimline above and nearly twice the best value per litre in this ranking. It carries 4.1 stars from 159 ratings with 57 per cent five-star and 9 per cent one-star, the highest complaint rate of the slimline group, and it is made from recycled plastic, which is part of what the price buys. What it does include is a complete kit: a stand, a lid, a tap and a rainwater downpipe diverter with a filter. The cheaper slimline comes with the tap and filler but no stand, so the £11.49 difference buys a stand, a filter and the recycled material. Its weight field says 2kg, which — like the 1kg quoted on the 210-litre butt — is not a real figure for a barrel with wall thickness. The reviews describe it well: a fantastic product, excellent value, easy to install, very well built and sturdy, which is what recycled plastic buys, since these barrels are moulded in plain shapes rather than shapely ones. At 40cm square and 90cm high it needs less space than any large butt here. Pros: Made from recycled plastic; A complete kit: stand, lid, tap and downpipe diverter with filter; 40 x 40 x 90cm: the smallest footprint in this ranking; 159 ratings at 4.1 stars for a £44.99 product; Buyers describe it as well built and sturdy Cons: £0.45 per litre: the dearest of the small butts; 9 per cent of its 159 ratings are one-star, the highest of the slimlines; Weight listed as 2kg, which is not real; £11.49 more than the slimline that comes with a tap ### 8. 2 x 100 Litre Slimline Water Butts with Stands, Black - Price: £66.99 | Amazon rating: 4.2 from 218 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/pluto-2x100l - Buy on Amazon: https://www.amazon.co.uk/dp/B0BZQ6H699?tag=ranked10-21 Two 100-litre slimline butts for £66.99 — with a capacity field that counts one of them, not the pair. Two 100-litre slimline butts for £66.99, which works out at £0.335 per litre for the 200 litres you receive — the same value as the single slimline kit above, doubled. They carry 4.2 stars from 218 ratings with 59 per cent five-star and 8 per cent one-star, and each is 32 x 36 x 95cm, so the pair needs two narrow spaces rather than one wide one. Its capacity field says 100 litres, counting one butt rather than the pack: the mirror image of the two-pack of bird feeders in our other ranking, where a listing sold a pair and quoted the specs of one. Here, at least, the price makes it clear that you get two. The reviews are about the result rather than the product: they blend in nicely, they came with everything needed, and one buyer could not believe how quickly they filled, with plenty of pots and baskets to water. Two butts also solve a problem a single one cannot: with the diverter feeding them in sequence, the first overflows into the second, so a heavy downpour is not wasted once the first is full. Pros: 200 litres of storage for £66.99: £0.335 a litre; Two stands included; Each is 32cm deep, so both fit narrow spaces; A sequence of two butts captures more of a downpour; 218 ratings at 4.2 stars Cons: The capacity field counts one butt, not the pair; 8 per cent of its 218 ratings are one-star; Two footprints and two connections to make; £66.99 in one go against £33.89 for one butt ### 9. NOVECRAFTO 350L Water Butt Kit with Tap, Stand and Cleaner Treatment - Price: £224.95 | Amazon rating: 4.2 from 59 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/novecrafto-350l - Buy on Amazon: https://www.amazon.co.uk/dp/B0CQYXNC7P?tag=ranked10-21 The largest butt in the ranking at 350 litres — and the worst value per litre at £0.643, 2.7 times the cheapest. The largest water butt here at 350 litres, and the worst value: £224.95 is £0.643 per litre, 2.7 times the cheapest storage in this ranking and more than twice the best value among the large butts. It carries 4.2 stars from 59 ratings with 60 per cent five-star and 9 per cent one-star, and it is a 77 x 36 x 135cm barrel — narrow and tall, which is how 350 litres fits down a side return — supplied with a tap, a stand, a 450g cleaner treatment and a smart overflow at the diverter level. What the money buys is a considered kit: the cleaner treatment is a consumable most listings ignore, and the overflow directs excess rain rather than letting it pool at the base. It also buys a 135cm height, the tallest here, which lifts the tap for filling a watering can. The number to weigh against the price is the weight of the contents: 350 litres is 350kg, more than a third of a tonne, standing on a stand in a garden. Whatever it stands on has to take that load, and at 36cm deep it will often be beside a wall on soft ground. At £0.643 a litre its case is the shape and the kit rather than the storage. Pros: 350 litres: the largest capacity in this ranking; A 450g cleaner treatment and a stand included; A smart overflow at the diverter level; 135cm tall and 36cm deep, so it fits down a narrow gap; 4.2 stars from 59 ratings Cons: £0.643 per litre: the second-worst value here; 9 per cent of its 59 ratings are one-star; 350 litres weighs 350kg when full; £224.95 against £58.99 for 210 litres ### 10. NOVECRAFTO Amphora Water Butt 210L in Terracotta with Tap Kit - Price: £149.95 | Amazon rating: 4.2 from 117 ratings - Full review: https://www.ranked10.co.uk/garden/best-water-butt/novecrafto-210l-amphora - Buy on Amazon: https://www.amazon.co.uk/dp/B0CQYWQWKW?tag=ranked10-21 The same 210 litres as the best-value barrel here, for £149.95 — £0.714 a litre, two and a half times the price of the water. The dearest storage in this ranking per litre: 210 litres for £149.95, which is £0.714 — two and a half times what the best-value 210-litre butt here charges for the same water. It carries 4.2 stars from 117 ratings with 62 per cent five-star and 5 per cent one-star, is moulded in HDPE in a terracotta colour, and is shaped as an amphora rather than a barrel, with a tap kit included. Put the two side by side and the argument becomes clear: £58.99 or £149.95 for 210 litres, and 210kg of water either way. What the extra £91 buys is appearance and drainage: the amphora shape conceals the barrel in a garden, the terracotta colour passes as a pot, and the listing describes a smart overflow at the diverter level so excess rain is directed rather than left to pool. Nothing about it holds water better. One review supplies the practical detail the listing omits: you need a 26mm drill bit to make the hole. That instruction belongs in the box, and on a butt at this price it is worth knowing before it arrives. If the butt will be seen, this is the one to buy; if it goes behind a shed, £0.281 a litre is the same water. Pros: An amphora shape that conceals a 210-litre butt in a garden; A terracotta colour that passes as a planter; A tap kit and a smart overflow included; 117 ratings at 4.2 stars; HDPE, so it is a plastic butt wearing a better shape Cons: £0.714 per litre: the dearest in this ranking; Two and a half times the £58.99 barrel for the same 210 litres; A 26mm drill bit is needed, per a reviewer; 5 per cent of its 117 ratings are one-star ## Verdict What we would buy. The STORM TRADING 210-litre butt at £58.99 is the pick: £0.281 a litre, 537 ratings at 4.5 stars and a stand in the kit. If a warranty matters, the Harcostar 227-litre at £69.99 offers the only five-year cover here and the only believable weight. The Zinc 227-litre is the best-rated butt in the ranking at 4.6 stars. For a narrow gap, the 100-litre slimline at £33.50 has 800 ratings behind it and fits in 32cm. And if you want to spend as little as possible per litre, the generic 210-litre at £49.99 is £0.238 — with the caveat that its own listing cannot tell you what it weighs. What the listings will not tell you. Divide the price by the litres before buying: the same water varies threefold. Do not trust a single capacity figure — check the title, the bullet and the specification field, because 26 gallons and 100 litres can appear together. A full butt weighs a kilogram per litre, so a 210-litre butt and its stand put a quarter of a tonne on the ground beneath them. A stand lifts the tap to watering-can height; without one you will be filling from the bottom. Slimline costs more per litre and saves space, which is a fair trade in a small garden. And if the butt will be seen, remember that the amphora premium is two and a half times the price of the water. Everything on this page comes from the Amazon listings, collected on 11 September 2026.
