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 Nordic Square Single Tap
What we like
- Dedicated 100°C boiling tap that adds to an existing mixer
- Squared spout matches handleless and modern kitchens
- Child-safe handle: press twice and turn before boiling water flows
Watch out for
- Boiling water only, so it does not replace your mixer tap
- Two finishes: polished chrome or stainless steel
- £1,050 for boiling alone is premium against a 3-in-1
