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 Front
What we like
- Front-facing handle clears space behind the spout
- Ergonomic lever easier for users with limited reach
- Works against backsplashes and windowsills others cannot
- Red Dot Design Award 2023 for the form factor
Watch out for
- £1,400 RRP is dearest Quooker 3-in-1 in current range
- Newer model has limited long-term Trustpilot data
- CUBE filter cartridge replacement adds ongoing cost
- Front controls less discreet than top-mounted alternatives
