Size is a claim about your pressure, not about luxury · review
The only rain head in this hub that publishes its flow WITH the pressure — under 8 litres a minute at 3 bar — and the only one whose saving can therefore be checked.
The bottom line The head to buy on evidence rather than adjectives. Its 40 % headline still has no baseline; its 8 l/min at 3 bar does the work instead.
A round ABS rain head of Ø 22.5 cm in black, with a fitted water-saving insert, a brass ball joint, a universal ½ in connection and stated suitability for a ceiling arm.
Under 8 litres per minute at 3 bar.
Almost every water-saving claim in this catalogue is a percentage with nothing behind it. This one publishes the litres and the pressure they were measured at, which is what a specification actually is.
“Up to 40 % saving.” Against what? No baseline head, no baseline flow. The 8 l/min figure below it does the real work; the percentage adds nothing.
Less hot water drawn means less energy to heat it. That is the honest version of a water-saving claim: the saving on the bill is mostly the heating, not the water.
ABS, with a brass ball joint. Lighter and cheaper than the stainless heads in this hub, with metal where the pivot has to hold. What is not stated is whether the nozzles are silicone, which decides how they behave in hard water.
On sale from 31 € to 48 € on the German, Italian and Spanish Amazon stores at the time of checking.
Also on sale on the British Amazon store, in the local currency: the range above is measured on the euro stores only.
The French Amazon listing is priced above 1.6× the cheapest store, which is normally a reshipping offer rather than a local price; it is left out of the range above.
Listed but with no offer on the American Amazon store — the reference exists there and nobody is currently selling it.

It is around the level most modern water-saving heads work at, and it is the figure to compare against your existing head — which, if it is old and unrestricted, may be moving twice that. The saving is real; whether it feels enough depends on the head's design as much as the number.
Because flow rises with pressure. "8 l/min" alone is not a specification. "Under 8 l/min at 3 bar" is one, and it is the only such statement on this page.
Rain head · 20 cm round (8 in) · stainless, electroplated · G1/2 · 360° ball joint · TPE nozzles
A 20 cm round stainless head with an air-injected pattern and TPE nozzles, at the price of a takeaway — and without a single flow figure.

≈ £26 / 20 €
Rain head · 20 × 20 cm square (8 in) · stainless · G1/2 female · 360° rotation and 15° tilt · 100 silicone nozzles
A 20 cm square stainless head that publishes its nozzle count and its tilt angle — two small facts nobody else on this page bothers to give.
Best for: A modern square-fitting bathroom in a hard-water area, where the nozzles need to be wiped rather than soaked.
≈ £27 / 20 €
Rain head · 30 × 20 cm rectangular · 304 stainless and ABS · G1/2 · 360° ball joint · silicone nozzles
The widest face in this hub for the lowest price — and a listing that calls a 30 × 20 cm rectangle square, which is worth noticing before you order.
Best for: A large enclosure on strong mains pressure, where face area is the point and the exact shape needs checking first.
