What we like

  • 7-litre tank serves up to 14 cups in one go, sized for larger households
  • Four separate waterways and no electronic components in the tap

  • Marine-grade stainless steel tap, engineered in the UK

Quooker Classic Fusion Square

What we like

  • Period styling in a squared spout for Shaker and classic kitchens
  • Patinated brass develops a genuine patina rather than a printed lacquer
  • Same PRO3 tank and 100°C boil as the rest of the Fusion range

Watch out for

  • 3-in-1 only: no filtered or chilled water without the CUBE upgrade
  • Patinated brass needs an occasional beeswax wipe
  • Fewer finishes than the standard Fusion (no gold, gunmetal or black)
