Specs last updated 17 June 2026

The best-selling all-in-one in a squared-off spout

The Fusion Square is the angular sibling of Quooker's best-selling Fusion Round. It delivers the same 100°C boiling water alongside regular hot and cold from a single fixture, with a squared spout and base that suit handleless and modern kitchens. Pair it with the CUBE module for filtered, chilled and sparkling water. Offered in seven finishes from polished chrome to 24-carat gold.

What we like

  • True 100°C boil from the same PRO3 tank as the Fusion Round
  • Squared profile suits handleless and contemporary kitchens
  • Seven finishes including patinated brass, gold and rose copper
  • Quooker UK holds a high Trustpilot rating across 12,000+ reviews

Watch out for

  • £1,250 buys boiling plus standard hot and cold only
  • Filtered, chilled or sparkling water needs the separate CUBE module
  • 2-year warranty on tap and tank (SWAP is a paid out-of-warranty tank swap)

Our take

The Quooker Fusion Square reviewed

The Fusion Square is the same tap as Quooker's best-selling Fusion Round with one difference that you can see and not feel: the spout and base are squared off rather than rounded. Underneath sits the identical 3L PRO3 tank, the same genuine 100°C boil, and the same roughly 10W idle draw, so nothing about the performance changes when you pick this shape over the round one.

The reason to choose it is the kitchen, not the spec sheet. A squared profile reads as more architectural and tends to suit handleless, slab-door and contemporary layouts where a round spout can look slightly soft. The finish range is the full seven, from polished chrome through gunmetal and rose copper to the patinated brass and 24-carat gold options, so you can match it to cabinetry hardware rather than settle.

The trade-offs are exactly the Fusion Round's. At £1,250 you are paying premium money for boiling plus standard hot and cold, and filtered or chilled drinking water still means bolting on the separate CUBE accessory. If a built-in filter matters more than the boil temperature, a 4-in-1 like the Franke Instante gives you that out of the box for less. Buy the Fusion Square for the temperature, the build and the squared look, not because it does the most for the money.

Running cost

What this tap really costs to own.

Headline price is half the story. The Quooker Fusion Square draws around 10 W at idle and reheats whenever the tank cools. Use the calculator with your own electricity tariff and household usage to see the 10-year total.
