Key Features

The composite material uses 80% quartz mixed with 20% acrylic resin for a super hardwearing material; Molded using a special computer-controlled casting process, it creates sinks that are extremely resistant to heat (up to 180° C), dents, scratches and stains; It also doesn’t fade under UV light, meaning it will retain its good looks as well as its premium performance; The velvety smooth pore-free surface is hygienic and easy to clean as well as 100% food-safe

Minimize the sound of running water and clanging pots and pans with the GROHE Whisper technology; A special insulation on the underside of the sink reduces noise for a more peaceful kitchen

Thanks to innovative manufacturing techniques, all GROHE composite sinks have a depth of at least 20cm, meaning they can handle even your largest pots and pans

The GROHE QuickFix system (kit supplied) makes installing your sink quick and hassle-free with no additional equipment required; The sinks come with two pre-punched tap holes, making them fully reversible; And the clever space-saver siphon design optimises the space under the sink, leaving plenty of room for storing essentials out of sight

No more plunging your hands into dirty water – this automatic waste is operated via remote control, keeping your hands clean and dry
