Hansgrohe’s new RainBrain touchscreen shower system can store up to four presets and offers five functions, any three of which can be used simultaneously. The system’s warm-up function preheats the water to preset temperatures. It also offers water cascade, antiscald, and hot and cold shower options. The system can pause the water flow, control external lighting, and interface with a Bluetooth-compatible device to play music. • hansgrohe-usa.com
