Comments about Grohe Rainshower System:

This product is meant at a retro-fit when redesigning a bathroom. You need an external Grohe thermostat water valve which is not recommended when you pick this item to purchase. You must buy seperately and there will be two hoses that connect to a quick release valve only one at a time when combined with hand shower. [...] A proper photo of the complete setup should be available; however, Grohe has a photo on their site which shows the rainshower and the Sena handshower both connected to the water control with only a hose for the handshower. The water valve in the photo is not available and a press photo only. Otherwise it would be a great product. Needs to be designed and advertised better.
