Wave Cosmopolitan

Wave Cosmopolitan Single-lever bath/shower mixer 1/2"


Product Number 23209000

The GROHE Wave Cosmopolitan bath mixer has been designed for the modern world, with effortless style and solid performance. The single-lever bath mixer is designed to be wall-mounted, with a sturdy metal lever handle for tactile operation. Inside the GROHE SilkMove ceramic cartridge delivers smooth and precise volume and temperature control year after year. And the handy automatic diverter makes it super easy to switch between bath inlet and hand shower. An integrated non-return valve in the shower outlet prevents backflow of waste water into the water supply. And the multi-layered coating of the hard-wearing and easy-care GROHE Long-Life finish ensures a brilliant shine that lasts for years to come. The adjustable minimum flow rate is 2.5 l/min. Installation is surprisingly easy: Thanks to the GROHE QuickSpanner the mixer can be mounted with no need for further tools. If you need more guidance, watch our QuickVideo or have a look at the QuickGuide.
