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
Hanstrom Saxan 4-in-1
What we like
- Distinct square D-shape spout, Hanstrom's current square 4-in-1
- Touchscreen presets (75/85/90/95°C) for tea, coffee and noodles
- Genuine 4-in-1 with carbon-and-phosphate filtration (filtered boiling and filtered cold)
- Usually sells around £399, undercutting most premium 4-in-1s
Watch out for
- 75 to 98°C steaming hot, not a true 100°C boil
- Boiler warranty is only 1 year (tap 2 years); 3 years needs a paid extension (~£99)
- Permanent 'sale' pricing makes the £569 RRP a soft anchor
- Younger brand with thin published specs (no peak wattage)
