Strengths and trade-offs

InSinkErator 3N1 J-Shape

Quooker Nordic Round Twintaps

What we like

  • Boiling tap and matching mixer supplied as one coordinated set
  • Dedicated boiling spout, so no risk of an accidental boiling dispense from the mixer
  • Choice of PRO3, COMBI or COMBI+ tank

Watch out for

  • Needs worktop space and two tap holes
  • Two finishes: polished chrome or stainless steel
  • Steeper than a single 3-in-1 that covers the same functions
