Strengths and trade-offs
InSinkErator 3N1 J-Shape
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
