Hygienic, touch-free operation – with an infrared sensor
The infrared sensor detects hand movement and activates water flow only while hands are in range, eliminating the need to touch the tap. Reduced skin contact means fewer transfer points for germs and less frequent deep cleaning.
Hands-free control helps keep the basin area cleaner and reduces cross-contamination, which is useful for families and high-traffic bathrooms.
Lower water consumption – thanks to GROHE Water Saving technology
Water Saving technology moderates flow to deliver a full jet while using less water, and automatic shut-off prevents unnecessary running. The system is calibrated to preserve performance while cutting usage by up to 50% as stated by the manufacturer.
Reduced water use helps manage household bills and supports greener routines without sacrificing the feel of a full water jet.
Low maintenance finish and simple cleaning – with a hard-wearing chrome surface
A smooth chrome finish resists grime build-up and is designed for quick surface cleaning, requiring only a wipe with a dry cloth. The durable coating is intended to retain a luminous sheen over time.
Fewer cleaning tasks and a tap that keeps looking smart, making it well suited to busy bathrooms and family homes.

❓ Frequently Asked Questions
Q: Will the tap fit typical UK plumbing?
A: The tap has a G3/8" European connection and UK homes often use G1/2" fittings, so a pair of 15mm compression x 3/8" BSP male adaptors will be required if your supply uses G1/2". Adaptors are sold separately.
Q: How does the touchless function reduce water use?
A: An infrared sensor detects hand movement so water flows only when required, and GROHE Water Saving technology moderates the jet to cut consumption by up to 50% while maintaining a full water feel. The combined approach limits wasted running time and volume.
Q: What is the recommended cleaning method?
A: A simple wipe with a dry cloth keeps the chrome finish looking glossy, thanks to the smooth, hard-wearing surface that reduces cleaning effort.
🏆 Our Verdict
Perfect for families and busy households that prioritise hygiene and easier cleaning routines. Touchless infrared control combined with GROHE's Water Saving tech and a durable chrome finish is the key selling point. While an initial plumbing check and possible adaptors are needed for some UK homes, long-term savings on water and lower maintenance make it a sensible investment.
