The best mortar buckets, compared.
Top pick: TDBS 42 litre flexi tub Best value: Best House 14 litre builders bucket, pack of 4 – Lowest unit price among rigid 14–15 litre packs that name mixing, at about £3.50 each, with a shared star line. Updated October 2026.
The usual trade pail is a round 14–15 litre builders' bucket with a wire handle, often labelled "3 gallon". Three imperial gallons are about 13.6 litres, so plan with the litre figure. The handle, volume marks and a capacity that matches the bag are what separate a useful tub. A 15 litre bucket holds the water B&Q cites for a 25 kg bag of plaster, not the finished gauge. Refina rates a 35 litre tub for one bag, and that tub is not here. Capacity, handle and marks are in the [mortar bucket buying guide](/hub/flooring-tools-and-accessories/mortar-bucket/sub/mortar-bucket-buying-guide). A mortar bucket is the plastic tub used to mix or carry mortar, plaster, cement or site water. Airflow's British pattern is sold as a 3 gallon / 15 litre bucket. A taller one-bag plasterers' bucket is the missing rung.

Question 1 of 2
What are you using the tub for?
The TDBS 42 litre flexi tub at £8.87 is one yellow flexible tub, listed at 480 x 480 x 380 mm, with built-in plastic handles and no lid. The star line is 4.8 from 53 amazon.co.uk reviews, the highest rating in this set and a much smaller file than the Faithfull tub. The bullets name garden, feed, laundry and tools, and they do not name mortar or plaster. Reviews doubt heavy loads and complain about splash and shape, which fits a wide soft wall rather than a tall plasterers' tub. Volume marks are not stated, and the catalogue colour field says Pack of 1 while the title says yellow. Refina rates a rigid 35 litre tub for one 25 kg bag of plaster; this listing does not make that claim, and a disagreement online about 42 litre flexi tubs is not a specification for this ASIN. It can be a light wide trug if you accept no graduations. It is the wrong default if you wanted a gauged mortar pail or a skim tub the maker rates for a bag.
Pros
Cons
Best for: You want a wide soft tub for light garden loads and you do not need printed marks or a mortar claim.
Less suitable: You are gauging mortar, carrying water on a wire handle, or mixing one bag of skim.
Specifications
Common questions
Is this a rigid builders' bucket?
No. It is one 42 litre flexible plastic tub. The title also calls it a builders bucket.
Are volume marks stated?
No. Graduations are not stated, and there is no lid.
What colour is stated?
The title says yellow. The catalogue colour field says Pack of 1.
The Best House four-pack at £13.99 is four black 14 litre buckets, about £3.50 each, which is the lowest unit price in this set. Each is described with a galvanised metal handle, a grip and a pouring lip, and the bullets name mixing cement and plastering as well as water and garden use. The 4.6 from 356 is shared with the one-pack and the two-pack, including overlapping text, so the count is not four hundred reviews of this carton alone. The title says made in the UK and the country field says China. No volume marks are stated, and 400 g is not given per bucket or per pack. At this unit price you are buying several gauging pails, not one tub for a 25 kg bag of plaster. It is the best value pick when you want four rigid buckets and you accept the shared reviews and the origin clash. It is a weak buy if you needed litre marks or a Britain line the catalogue confirms.
Pros
Cons
Best for: You want several cheap rigid 14 litre pails and you have accepted the shared review line and the origin clash.
Less suitable: You need printed gallon and litre marks, one confirmed country of origin, or a single tub for a 25 kg bag.
Specifications
Common questions
How many buckets are in this pack?
Four 14 litre buckets. The bullets name a galvanised metal handle with a grip and a pouring lip.
Does the listing claim cement mixing?
Yes. The bullets name mixing cement and plastering, as well as water and garden use.
Why does the review count match the other Best House packs?
The same 4.6 from 356, and overlapping review text, sit on the one-pack, the two-pack and this four-pack. The title says made in the UK and the country field says China.
The Best House single at £7.99 is one black 14 litre plastic bucket with a metal handle and a pouring lip, and the bullets name cement mixing and plastering. The amazon.co.uk line is 4.6 from 356 reviews, but that same star line and overlapping review text also sit on the two-pack and the four-pack, including comments about two buckets and four buckets, so 356 is not a sample of this ASIN alone. The title says made in the UK and the country of origin field says China. Volume marks are not stated, and the weight field of 400 g is not labelled as this bucket only. Handle complaints appear in that shared review pool, which is a known failure on wire handles, though this file does not show that this handle is weaker than Airflow's. A 14 litre pail is the right class for water and a small gauge, and the wrong class for a 25 kg bag. It is a poor match if you bought it because the title said Britain, or because you wanted a review sample separate from the multipacks.
Pros
Cons
Best for: You want one rigid 14 litre pail with a lip, and you have read that the star line is not unique to this pack.
Less suitable: You need a confirmed Britain origin, printed litre marks, or a review file that is only this single bucket.
Specifications
Common questions
Does the catalogue confirm the made-in-the-UK line?
No. The title says made in the UK. Country of origin is China.
What is in the pack?
One 14 litre bucket. The bullets name a metal handle and a pouring lip, and they name cement mixing and plastering.
Are the 356 reviews only for this single bucket?
The 4.6 from 356 and the review sample match the two-pack and the four-pack, including comments about two buckets and four buckets.
The Best House two-pack at £11.49 is two black 14 litre buckets, about £5.75 each, with a metal handle and a pouring lip and no lid. The bullets name cement mixing. The 4.6 from 356 reviews is the same shared line as the one-pack and the four-pack, so a comment about four buckets is not evidence that this pair arrived as described. The title says made in the UK and the country of origin is China. Volume marks are not stated, and the 400 g weight is not stated per bucket. Two 14 litre pails let you keep a gauge bucket and a water bucket separate on a small wall, and they do not add up to one 45 litre mixing tub. Handle complaints in that shared pool are the limit on reading "heavy duty" as a tested rim. Choose the pair when you want two cheap pails and you have read the origin clash; the four-pack is cheaper per bucket, and Airflow is the pack that states marks.
Pros
Cons
Best for: You want two rigid gauging pails and you will not treat the shared star line as a test of this pair alone.
Less suitable: You need printed marks, a confirmed UK origin, or one tub large enough for a full bag.
Specifications
Common questions
Does the listing name cement mixing?
Yes. The bullets name cement mixing, and they name a metal handle and a pouring lip. There is no lid.
Where does the listing say the buckets are made?
The title says made in the UK. Country of origin is China.
Is 4.6 from 356 only this two-pack?
No. The review sample is the same run of text as the one-pack and the four-pack.
The Faithfull FAIFLEX15Y at £7.04 is a yellow 15 litre polyethylene flex tub, and the bullets claim graduations in gallons and litres plus a five-year manufacturer guarantee. It is the only listing here with a large review file of its own: 4.5 from 595 amazon.co.uk reviews, describing garden use and small mixes rather than a full bag of cement. One review calls it too small for cement, and another reports a leak, which is what you would expect if a 15 litre tub was asked to take a 25 kg bag. The catalogue dimensions, 290 x 320 x 390 mm, do not match the bullet size of 330 mm diameter and 230 mm height, and the catalogue says a lid while the bullets do not describe one. The listed weight is 405 g and the country of origin is Israel, so this is a light knock-out tub, not a rigid carry pail with a pouring lip. It is the top pick in this set because the marks, the price and the review count line up for a small flexible mix. Skip it when you need a wire handle and a lip for carrying water, or a tub a maker rates for one bag of plaster.
Pros
Cons
Best for: You want printed marks and a soft wall for a garden trug or a small mix, and you will not fill it as a one-bag tub.
Less suitable: You need a rigid pouring lip and a wire carry, or a full bag of skim in one gauge.
Specifications
Common questions
Does the Faithfull tub state volume marks?
Yes. The bullets claim graduations in gallons and litres.
Is a lid described?
The catalogue field says yes. The bullets do not describe a lid, so the two parts of the listing disagree.
What capacity is stated?
15 litres. The bullets also say a 330 mm diameter and 230 mm height, which does not match the catalogue dimensions.
The M1SS pair at £21.99 is two black 45 litre tubs, and the bullets say each has two rope handles for a two-person lift, for dry and wet cement, plaster and mortar. That is the only listing in the set whose bullets name all three. The star line is 4.4 from 147 amazon.co.uk reviews, a separate count from the single M1SS tub. There is no lid and no volume marks. The catalogue lists 1.25 kg once and does not say whether that is one tub or the pair. Height is 300 mm and diameter is 520 mm, so this is a wide shallow tub made in the United Kingdom on this listing, not the tall plasterers' bucket Refina rates at 35 litres for one 25 kg bag. A full tub is a shared lift, not a bucket you walk with on one wire handle. It is the wide-tub option when two people will move it and you wanted plaster named on the page.
Pros
Cons
Best for: Two people will lift a wide tub and you wanted cement, plaster and mortar named in the bullets.
Less suitable: You need a one-hand carry, printed marks, or a tall tub a maker rates for one 25 kg bag.
Specifications
Common questions
What is in the pack?
Two 45 litre round tubs. Each tub has two rope handles, which the bullets describe as a two-person lift.
Is mortar named on the listing?
Yes. The bullets say mixing and transporting dry and wet cement, plaster and mortar. There is no lid.
Does the weight mean one tub or both?
The catalogue lists 1.25 kg once. The file does not state whether that is per tub or for the pair.
The TDBS 14 litre builders bucket at £6.99 is a single black plastic pail with a metal handle, a plastic grip and a spout, and the bullets name cement mixing and concrete mixing. Across 4.4 from 90 amazon.co.uk reviews it is the cheapest single listing in this set, at the size used for water and a small gauge rather than a whole bag. The title prints both 14 litres and "3 gallon", while three imperial gallons are about 13.6 litres, so the litre figure is the one to plan with. Volume marks are not stated, so you cannot treat the inside as a printed gauge the way the Faithfull and Airflow listings claim. The catalogue colour field says Pack of 1 rather than black, beside a title that does say black, and there is no lid and no stated weight. It is a workable cheap pail for a small sand-and-cement gauge if you measure with one bucket and keep the mix below the rim. It is the wrong tub if you meant to tip in a whole 25 kg bag of plaster.
Pros
Cons
Best for: You want one cheap rigid pail for water or a small cement gauge and you will measure by the bucket rather than by printed marks.
Less suitable: You need litre marks inside the bucket, a whole bag of plaster, or a soft wall you can knock dry material out of.
Specifications
Common questions
Does this TDBS listing name cement mixing?
Yes. The bullets name cement mixing and concrete mixing, and they also name a built-in spout.
What colour does the listing give?
The title says black. The catalogue colour field says Pack of 1, not a colour name.
Is a lid included?
No. The listing does not include a lid.
The Airflow pack at £34.79 is five blue 15 litre buckets, about £6.96 each, with a metal handle, a plastic handhold, a pouring lip and internal markings in gallons and litres. A bullet says made in Britain and states a five-year guarantee; the catalogue country field is absent, so the Britain line is a bullet rather than a filled origin field. The star line is 4.3 from 78 amazon.co.uk reviews. Weight and dimensions are not in the file, and there is no lid. The bullets name mixing and plastering. Fifteen litres is the trade shorthand often printed as 3 gallon, while three imperial gallons are about 13.6 litres, and this size holds gauging water rather than a finished 25 kg plaster mix. Wire handles on other Invincible-style buckets bend in separate buyer comments, and that is not a test of this Airflow pack. It is the rigid pack to choose when you want printed marks and you will pay more per bucket than the Best House four-pack.
Pros
Cons
Best for: You want a pack of rigid pails with printed marks and you have read the Britain line as a bullet, not as a catalogue country.
Less suitable: You only need one bucket, you need the lowest unit price, or you are mixing a whole 25 kg bag in one go.
Specifications
Common questions
How many buckets are in the Airflow pack?
Five blue buckets. Each is stated as 15 litres, also called 3 gallons, with a metal handle, a plastic handhold and a pouring lip.
Does the listing say where they are made?
A bullet says made in Britain. The catalogue country field is absent. A five-year guarantee is also in the bullets.
Are volume marks stated?
Yes. Internal markings in gallons and litres are stated. There is no lid. Weight and dimensions are not stated.
The M1SS single at £10.99 is a black 45 litre round plastic tub listed at 1.25 kg, with a stated diameter of 520 mm that does not match the 26 cm catalogue width. The title says rope handles and the catalogue handle material says plastic, so the listing does not agree on the grip. The bullets do not say it mixes plaster, even though the page asks that question, while UK reviews in the file do describe mixing mortar, cement and plaster. The star line is 4.2 from 55 amazon.co.uk reviews, the weakest rating among the nine. There is no lid and no volume marks. A full 45 litres is not a one-person carry: 15 litres of water is already 15 kg before the bucket, and HSE publishes lifting filters rather than a safe kilogram for these tubs. Country of origin is United Kingdom on this file. Buy it only after you have checked the handle on the live page and you have a second person for a full tub.
Pros
Cons
Best for: You have checked which handle the live page is actually selling and two people can move a full 45 litre tub.
Less suitable: You need the bullets to name plaster, one agreed size line, or a bucket you can carry alone.
Specifications
Common questions
Do the title and the catalogue agree on the handles?
No. The title says rope handles. The catalogue handle material is plastic.
Do the bullets say it mixes plaster?
No. The listing asks that question and does not answer it in the bullets. UK reviews describe mixing mortar, cement and plaster.
What capacity and lid are stated?
45 litres, and no lid. The diameter on the listing is 520 mm, which does not match the 26 cm width in the catalogue.
Nine amazon.co.uk listings were scored on 19 October 2026 from the review line, the litres and handle printed on the page, and the shelf price in GBP. This is not a lab test. No listing in this set states a maximum load in kilograms, so load is not a scoring line. Weights are Amazon evidence 30, listing fit 30, value 25 and job honesty 15.
Amazon evidence
30%Star rating and review count on amazon.co.uk. A 4.5 from several hundred scores higher than a 4.8 from about 50. The Best House 4.6 from 356 is one shared line across three pack sizes, so each of those listings scores it once.
Listing fit
30%Stated litres, a handle you can read, a pouring lip where claimed, and volume marks if the bucket is a gauge. A mixing use named in the bullets scores here. A title that disagrees with the country field, the handle, the size or the lid loses points.
Value
25%Shelf price in GBP against a capacity and a review count you can read. The lowest price per rigid 14–15 litre bucket, among packs that name mixing, is the best-value case. A low price does not win this block when the bullets do not name the job.
Job honesty
15%Whether the stated capacity matches a small gauge or a wide tub, and whether the bullets match that job. A wide flex tub whose bullets do not name mortar or plaster cannot take this block in full.
Nine tubs sit in this table, from a 14 litre rigid pail to a 45 litre wide tub. Prices on 19 October 2026 run from about £6.99 to about £34.79. Buy the capacity against the bag before you compare the star line. A 14–15 litre bucket is for water and a small gauge. A maker-rated 25–35 litre tub is for one 25 kg bag, and that tub is not in this set.
A mortar bucket is the plastic tub used to mix or carry mortar, plaster, cement or site water. The usual trade pail is a round 14–15 litre builders' bucket with a wire handle. Airflow's British pattern is sold as a 3 gallon / 15 litre bucket. Three imperial gallons are about 13.6 litres, so the litre figure is the one to plan with. The nine amazon.co.uk listings kept here are small rigid buckets, two flexi tubs and two 45 litre tubs. A taller one-bag plasterers' bucket is the missing rung.
B&Q cites about 11–12 litres of water for a 25 kg bag of plaster. That water fits a 15 litre bucket. The finished gauge does not. Refina rates a 35 litre tub for one bag, and that tub is not in this set.
Three imperial gallons are about 13.6 litres. Titles that print both 14 litres and 3 gallon, or 15 litres and 3 gallon, are using trade shorthand. Plan with the litre figure.
Best House titles say made in the UK while the country field says China. The single 45 litre M1SS title says rope handles and the catalogue says plastic. Adding the three Best House 4.6 from 356 counts treats one shared line as three samples.
Use 14–15 litres for water, gauging and a partial mix. The rigid pails in this set are the TDBS 14 litre, the three Best House packs and the Airflow five-pack of 15 litre buckets. Use a maker-rated 25–35 litre tub for a whole 25 kg bag. Refina rates a 35 litre tub for one bag. None of these listings is that tub. A 40–45 litre tub is a wide, often two-person, muck tub. The TDBS 42 litre flex tub does not name mortar or plaster. The M1SS pair does, and the bullets describe a two-person rope lift.
Wire with a grip, ropes for a shared lift, or built-in handles on a flex tub. Bent handles are the failure reviewers and trade sellers both describe. A pouring lip does not reinforce the rim. Faithfull states a metal handle in the catalogue only, with gallon and litre marks, and the catalogue lid field does not match the bullets. Airflow states a metal handle with a plastic grip, a pouring lip, and internal gallons and litres.
Three typical situations, each with a recommendation from this comparison.
You want printed marks and a soft wall for a garden trug or a small mix, and you will not fill it as a one-bag tub. The Faithfull 15 litre flex tub is the top pick at about £7.04, with 4.5 from 595 reviews. One review calls it too small for cement.
You want several rigid 14 litre pails and you have accepted the shared review line and the origin clash. The Best House four-pack is the best value at about £13.99, about £3.50 each. The 4.6 from 356 is shared with the other packs, and the title says UK while the country field says China.
Two people will lift a wide tub and you wanted cement, plaster and mortar named in the bullets. The M1SS pair is two 45 litre tubs at about £21.99, with 4.4 from 147 reviews. A full tub is a shared lift, not a one-hand carry.
The top pick is the Faithfull 15 litre flex tub at about £7.04. It has 4.5 from 595 reviews, gallon and litre marks and a stated five-year guarantee. The catalogue size and the lid field clash with the bullets, and reviews describe small mixes, with one calling it too small for cement. The best value is the Best House four-pack at about £13.99, about £3.50 each, the lowest unit price among rigid 14–15 litre packs that name mixing. The 4.6 from 356 is shared across three pack sizes, and the title says UK while the country field says China. A 4.8 from 53 reviews on the 42 litre TDBS tub does not outscore the Faithfull file when the bullets do not name mortar.
Best House 14 litre builders bucket, pack of 4
Lowest unit price among rigid 14–15 litre packs that name mixing, at about £3.50 each, with a shared star line.
