Transform yours and your family’s showering experience by switching easily to the advanced comfort and convenience of the GROHE Grohtherm 1000 shower set

The GROHE Grohtherm 1000 thermostatic shower set offers the latest water-saving technology plus a range of comfort and safety features to enhance your daily shower. It comes with a GROHE Grohtherm 1000 thermostatic shower mixer (centre distance 120mm, without connection unions), a Tempesta Cube 110 hand shower, a 600mm rail and a 1750mm hose. The mixer’s GROHE TurboStat technology ensures a constant supply of water at the perfect temperature with no unpleasant fluctuations. The solid GROHE MetalGrip ergonomic handles give a sure grip, even with soapy hands. While the GROHE CoolTouch design means the entire thermostat body will never get too hot to touch. The GROHE Water Saving function reduces water and energy consumption – perfect in combination with the hand shower. It’s also family-friendly, as the GROHE SafeStop override button is set at 38°C to prevent children in particular from unintentionally turning up the water temperature too high. The optional GROHE SafeStop Plus temperature limiter can be set at 43°C for an extra level of safety. And in case the cold water supply completely fails, an automatic safety shutdown reduces the water flow to a minimum. The 110x110mm hand shower features 2 sprays to suit different moods: the relaxing Rain eases stress, while the focused Jet is ideal for rinsing hair after shampooing. Both are easy to access using the innovative GROHE SmartSwitch diverter on the back of the shower head. The GROHE DreamSpray technology matches the flow of water from each nozzle, for a uniform spray pattern. It’s water efficient too, with the flow limiter that significantly reduces water consumption without compromising on performance. A minimum of 1.0 bar of pressure is recommended. GROHE SpeedClean enables you to brush the nozzles free of limescale with just a finger. The ShockProof silicone ring protects the hand shower itself, or the shower tray or bathtub, from damage if it’s accidentally dropped. The sturdy hose is built to revel in hard work and can withstand water pressure up to 5 bar, tension up to 50kg and heat up to 70°C. The rail comes with a gliding element and swivel holder, so adjusting the height and angle of the shower is super easy. Thanks to the GROHE FastFixation installation system the upper bracket is variable in height, meaning it can be fitted to existing drill holes. And with the dazzling but hard-wearing GROHE Long-Life finish, this set will stay looking pristine for years to come.
