The best granite parasol bases, compared.
Top pick: Garden Marketplace 25 kg plate – Highest score at 77: 25 kg, 47 x 47 cm, a cantilever cross line, and 4.8 from 16 with 12 UK texts, at about £64.99. One plate is not the full ballast. Updated 22.10.2026.
A granite parasol base is a heavy stone weight for a garden parasol. On UK listings that name covers two different objects: a flat plate that sits on a cantilever cross, and a block with a metal tube for a centre pole. You buy one for a patio because a water-filled plastic shell can leak, while a polished slab stays outdoors and does not need filling. You recognise a useful listing by the kilogram figure, whether a socket is included, and whether the page describes the same object you need. A cantilever takes plates on the cross, or a base the maker rates for a free arm. A centre-pole socket should name a pole diameter, 32 mm, 38 mm or 48 mm. The figure that matters is the total weight for that canopy, from the parasol maker, not one tile. Grooves are not wheels. Wheels help on paving and sink on a lawn. Stairs favour a base you fill on site. Plate or socket, and how that total is chosen, is in the [granite parasol base buying guide](/hub/sun-shades/granite-parasol-base/sub/granite-parasol-base-buying-guide).

Question 1 of 2
What are you weighting?
Garden Marketplace B07CTT9M2Z is a 25 kg polished granite plate, 47 x 47 cm, at about £64.99 on amazon.co.uk, with 4.8 from 16 ratings. The stored listing holds 12 United Kingdom reviews. Those texts describe a plate that looks better than plastic weights, fits a cantilever cross, and, as two or four plates, held a 3 m or 3.5 m offset parasol. One reviewer received a cracked tile and got a replacement. The page does not answer whether it suits any parasol, whether it has a handle, or whether it is weatherproof. There is no pole socket. In this three-listing set it is the top pick on the star line and the stated specification. One plate is not the full ballast the seller describes.
Pros
Cons
Best for: You want a granite plate for a cantilever cross and you will buy two, or four if the patio is exposed.
Less suitable: You need a centre-pole socket, wheels, or one 10 kg spike for a washing line.
Specifications
Common questions
Will this plate fit any parasol?
The amazon.co.uk page asks that and does not answer. The bullets say it fits most cantilever cross bases and parasols up to 4 m. It has no pole tube.
Does it have a handle?
The page asks and does not answer. The bullets mention underside handling grooves for lifting and positioning, not a carrying handle.
How many plates does the seller suggest?
The listing sells one 25 kg plate and says at least two, with four advised in a more exposed place.
B0HB4M7WSZ is a Generic listing at about £68.99. The title claims a 10 kg curved grey granite base that is also a ground spike for a rotary washing line and cloth airer. The model number is KM-PuFzpl. Dimensions, a pole diameter, a manufacturer, and a star line are absent. The bullets claim easy assembly and also call it lightweight beside the 10 kg figure. The image URL is the same as the dearer generic. Nothing in the file shows UK buyers describing a granite plate on a cantilever.
Pros
Cons
Best for: You are comparing the cheaper of the two generic 10 kg curved listings and you can check the pole size on the live page before you buy.
Less suitable: You need a reviewed 25 kg plate for a cantilever cross.
Specifications
Common questions
Is this a cantilever granite plate?
The title calls it a 10 kg curved grey granite parasol base and a ground spike for a rotary washing line. It does not give 47 cm plate dimensions or a cross-base fit.
What pole size does it take?
The bullets say most standard-sized poles and do not print 32 mm, 38 mm, or 48 mm.
Are there UK reviews?
The stored listing has no star line and no review text. First available is listed as 23 July 2026.
B0HJ5JMTTK repeats the 10 kg curved grey granite title used on the cheaper generic and uses the same image URL, at about £77.99. Brand and manufacturer are Generic, model A-1, part number KM-THnCJ8, one item, country of origin China. The bullets say you insert a washing line or a parasol and claim rust resistance. Dimensions, a pole diameter, a first-available date, and a star line are absent. It is not a reviewed cantilever plate.
Pros
Cons
Best for: You only need this row if you are checking the dearer generic ASIN against the about £68.99 twin.
Less suitable: You want a reviewed granite plate with printed dimensions for a cantilever.
Specifications
Common questions
How is this different from the cheaper curved listing?
The title and the image URL match. This listing is about £77.99, model A-1, part KM-THnCJ8, one item, country of origin China. The other generic is about £68.99, model KM-PuFzpl.
Does the page name a pole diameter?
No. The bullets say you insert a rotary washing line or a parasol. They do not print 32 mm, 38 mm, or 48 mm.
Are there UK reviews?
The stored listing has no star line and no review text.
Scores use the three amazon.co.uk listings kept on 20 October 2026. There is no laboratory wind test. No listing is treated as certified to BS EN 581. A missing star line scores 0 on the star block and on the review blocks. Review text is not copied into the specification table. Weights sum to 100. The highest score is the top pick in this set only. Unanswered questions on any parasol, a handle, and weatherproofing cost the 25 kg plate 4 points. A lightweight claim beside 10 kg costs the cheaper curve 3 points. A title and image URL shared with the cheaper generic costs the dearer listing 4 points. Best value is withheld. The only evidenced plate is already the top pick, and one product does not carry both awards. The 10 kg listings are not best value: no reviews, no dimensions, and a higher price per stated kilogram.

Review outcome
25%Repeated praise in the stored UK texts scores. A cracked arrival pulls the block down. No reviews score 0. A quiet file is not a wind test.
Shelf value
20%GBP against stated kilograms and what the page includes. One 25 kg plate does not take the full block, because the seller still asks for two or four. An unverified 10 kg claim at a higher price per kilogram scores low.
You are choosing a stone weight for a garden parasol, and the name covers a flat plate and a socket block. The three amazon.co.uk listings captured on 20 October 2026 run from about £64.99 to about £77.99. Only one prints a weight, a size, a cantilever fit, and UK reviews. The other two claim a 10 kg curved base and a washing-line spike, with no star line. Total kilograms, a socket or its absence, and review evidence decide the buy.
A granite parasol base is a heavy stone weight for a garden parasol. UK listings use that name for two objects. A weight plate is one slab per foot of a cantilever cross, with no pole tube. A socket base is granite plus a metal tube, often with knobs and wheels, for a centre pole. A slab pack is several thinner pieces sold together. Fillable plastic is not granite. Granite-effect is a look: a title can say effect while a bullet says the piece is solid stone, so read both lines.
The 25 kg listing sells one plate and still says at least two, with four in a more exposed place. Ruma’s cantilever bands are about 90 kg and 120 kg. 25 kg alone is not a 4 m ballast.
A socket block, often with wheels, is for a centre pole. A cantilever needs plates on the cross, or a base the maker rates for a free arm. The reviewed plate here has no pole tube.
The two 10 kg curves share a title and an image URL, print no dimensions and no star line, and also claim a washing-line spike. That is not evidence of a granite plate on a cantilever. A parcel near 1 kg is not a 20 kg stone.
The first check is the parasol. A cantilever needs plates on the cross, or a base the maker rates for a free arm. A centre-pole socket is a different product, and a base stated for a centre post only does not become a free-arm weight because it is granite. The second check is the total kilograms for that model, not the shelf price of one tile. Garden Marketplace sells one 25 kg plate and says at least two, with four if the spot is exposed.
A plate has no pole tube. A socket listing should name 32 mm, 38 mm or 48 mm. Grooves help you position a slab. They are not wheels. Wheels help on paving and sink on a lawn. Stairs favour a fillable base you load on site. Evidence is UK review text that describes the same object: granite plates on a cantilever, not a calm-day guess and not a title that also spikes a rotary washing line. A missing star line scores 0. Twelve texts under a 16-rating line are a smaller sample than the star count.
Three typical situations, each with a recommendation from this comparison.
You want stone instead of a plastic shell, on a cantilever cross. The Garden Marketplace plate is 25 kg and 47 x 47 cm at about £64.99, with 4.8 from 16 ratings. Plan two plates, or four if the patio is exposed. One plate is not the ballast the seller describes.
You are comparing the cheaper of the two generic 10 kg curved titles, at about £68.99, and you can check the pole size on the live page before you buy. The title also calls it a washing-line spike. There is no star line, no dimensions, and no cantilever fit.
You only need this row if you are checking the dearer generic listing against the about £68.99 twin. It is about £77.99, model A-1, one item, country of origin China, with the same title and image URL. There is no star line.
The top pick is the Garden Marketplace 25 kg plate at about £64.99. It scores 77, the highest in this three-listing set: 25 kg, 47 x 47 cm, a cantilever cross fit, 4.8 from 16 ratings, and 12 UK texts. The seller still wants two plates, or four if the spot is exposed, and one review describes a cracked arrival. Best value is withheld. The only evidenced plate is already the top pick, so one product does not carry both awards. The two 10 kg curved listings, about £68.99 and about £77.99, are not best value: no reviews, no dimensions, and a higher price per stated kilogram. They share a title and an image URL, and neither is a reviewed cantilever plate.
