The GROHE RAINSHOWER SYSTEM brings a gentle summer shower to the bathroom. The functional form is achieved by reducing everything to the familiar and simple level. 120 shimmering emerald green silimer spray nozzles in the particularly large, oversize shower head with a diameter of 210 mm produce an opulent shower of rain enveloping the entire body. SPEED-CLEAN technology ensures that lime deposits do not stand a chance at the nozzles. Whether the water is to flow over the body from the shower head or through a hand shower supplied with the system is determined via an easy to operate knob known as the Aquadimmer. Temperature is controlled by a thermostat with central control of water and flow rate. The functions are illustrated by unambiguous pictograms designed for worldwide use.
