Quooker Flex vs Fusion – Complete Guide & Comparison

Quooker is one of the leading names in boiling water taps, offering a variety of models to suit different kitchen designs and needs. Two of their most popular options are the Quooker Flex and Quooker Fusion ranges. This guide compares both ranges in detail, including technical specs, finishes, installation tips, maintenance requirements, and known issues.

Quooker Flex Round Overview

The Flex Round is Quooker’s only boiling water tap with a pull-out hose. It dispenses cold, hot, and true 100°C boiling water from a single tap. With the addition of the Quooker CUBE, you also get chilled and sparkling water – making it a true 4-in-1 system.

  • 3-in-1 tap: Boiling, hot, and cold water
  • Flexible pull-out hose for cold/hot water
  • Double-push-and-turn safety for boiling water
  • Upgrade to 4-in-1 with Quooker CUBE
  • Available finishes: Chrome, Stainless Steel, Matte Black

Flex Tap Dimensions

  • Tap height: ~412 mm
  • Spout reach: ~220 mm
  • Rotation: 270°
  • Tap hole required: Ø 35 mm

Quooker Fusion Overview

The Fusion range offers a more minimal design without a pull-out hose. It’s available in three models: Round, Square, and Classic, with styles to suit both contemporary and traditional kitchens. All provide boiling, hot, and cold water from one tap, with the same CUBE upgrade potential.

Model Styles

  • Fusion Round: Smooth, curved spout
  • Fusion Square: Angular, geometric design
  • Fusion Classic: Traditional styling for period homes
