Strengths and trade-offs

Grohe Red Duo L-Size

What we like

  • Boiling, filtered and a full hot-and-cold mixer in one tap, no second tap hole
  • Large 5.5L boiling reserve (7L total) on the L-size boiler
  • Child-safe touch-button dispensing with ChildLock as standard
  • Sells around £1,625 at UK specialists, far below the £2,578 list price

Watch out for

  • 99°C dispense, not a true 100°C boil (despite Grohe’s "100°C" marketing)
  • At around £1,625 it is still a premium tap, though far below its £2,578 list
  • BWT filter must be changed yearly or every ~600L, an ongoing cost
  • Standard guarantee is 2 years (3 only with registration), shorter than InSinkErator or Franke

Quooker Classic Nordic Round Single Tap

What we like

  • Period styling for a dedicated boiling tap, including a nickel finish
  • Adds 100°C boiling without replacing a much-loved classic mixer
  • Same PRO3 tank and genuine 100°C boil as the rest of the range

Watch out for

  • Boiling water only, so it does not replace your mixer tap
  • £1,050 for boiling alone is premium against a 3-in-1
  • Three finishes only: chrome, stainless steel or nickel
