The GROHE Precision Flow thermostatic mixer for low pressure with shower rail set – safety and sustainability, attractively priced. Discover the smart thermostat that locks in your desired water temperature for a safe and sensational shower from the very start! The GROHE Precision Flow is the ideal upgrade to the convenience of thermostatic showering. GROHE's thermostatic cartidge ensures a constant supply of water at the perfect temperature with no unpleasant fluctuations. It's family-friendly too as the GROHE SafeStop override button is set at 38° C to prevent especially children from unintentionally turning up the water temperature too high. The optional GROHE SafeStop Plus temperature limiter can be set to limit to 43° C for an extra level of protection. And in case the cold water supply completely fails, an automatic safety shutdown reduces the water flow to a minimum. The GROHE EcoJoy technology reduces water and energy consumption – and when you need a full flow just press the EcoButton to release the handle. The included Vitalio Go 100 shower rail set consists of a 100mm diameter hand shower with a ShockProof silicone ring to protect it against drops or knocks, a 620mm shower rail and 1750mm hose. GROHE DreamSpray technology ensures an even flow of water for the relaxing Rain Spray, and the nozzles brush easily free of limescale thanks to the SpeedClean feature. The durable and easy care GROHE StarLight chrome finish keeps the whole shower set looking stunning for years to come. With the sleek shape it creates a stylish look.
