GROHE Blue Fizz: 3 carbonation levels with a stainless steel nozzle

Prices in euros from Amazon.de, as of 11 June 2026. Prices and availability may differ on Amazon.co.uk.

By Seydhan Cakmak · Editor-in-chief · Updated: · AI-translated from the German original

GROHE brings its tap expertise to the sparkling water maker: the Blue Fizz has three adjustable carbonation levels and a stainless steel injection nozzle that is easier to clean and more hygienic than plastic nozzles. The tilt-and-turn mounting with automatic gas release makes carbonating effortless. The CO2 cylinder is, however, not included, only a 0.85L bottle and cleaning powder.

GROHE Blue Fizz (31943K00): what works, what doesn't?

What works well

  • Three selectable levels: carbonation strength can be set precisely, more control than with push-button-only devices
  • Stainless steel injection nozzle: easier to clean and more hygienic than plastic nozzles, a real material advantage
  • Automatic gas release: the tilt-and-turn mounting vents by itself, so carbonating is effortless
  • GROHE exchange system: empty cylinders can be conveniently swapped for full ones via the GROHE shop

Points of criticism

  • CO2 not included: as usual with GROHE the cylinder is missing, and with a device price over €90 the CO2 costs come on top
  • Only one small bottle: with a single 0.85L bottle in the set the supply is tight, buying more is almost a must
  • Higher entry price: clearly dearer than the ready-to-use SodaStream, even though less is in the box

Build quality & everyday use

What carries the GROHE Blue Fizz (31943K00) in everyday use: three selectable levels (carbonation strength can be set precisely, more control than with push-button-only devices) and stainless steel injection nozzle (easier to clean and more hygienic than plastic nozzles, a real material advantage). We have to be honest about the weaknesses: CO2 not included. As usual with GROHE the cylinder is missing, and with a device price over €90 the CO2 costs come on top.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“GROHE Blue Fizz Sparkling Water Maker: three selectable levels and a stainless steel injection nozzle, and the trade-off is that CO2 is not included. At 8.1/10 a fair deal from €92.”

Frequently asked questions about the GROHE Blue Fizz (31943K00)

Does the GROHE Blue Fizz come with a CO2 cylinder?
No. The box contains the sparkling water maker, a 0.85L water bottle, a sample sachet of cleaning powder and the instructions, explicitly NO CO2 cylinder. A 425g cylinder later lasts for up to 60 litres.
What is the advantage of the stainless steel nozzle?
The stainless steel injection nozzle is easier to clean and is therefore considered more hygienic than plastic nozzles. Especially with a device that comes into contact with water every day, that is a sensible material advantage.
How many carbonation levels does the GROHE Blue Fizz have?
Three. You choose the desired strength before carbonating and then press once, done. That gives more control than devices with only a single push button.
How does fitting the bottle work?
The water bottle is inserted with a tilt-and-turn movement. The automatic gas release vents by itself after carbonating, so you can take the bottle off again effortlessly.
