Rhea boasts a modern, reduced design. The shower toilet is available in three different versions with voice control and efficient cleaning functions. A particularly functional feature is the integrated air purifier, which complements the high toilet version and is mounted onto the body similar to a cistern. The flat display indicates the air quality using a three-colour “traffic light” code. When the display lights up red, the air purifying system adds fresh air, free from bacteria and odours, to the bathroom.
