Skate Cosmopolitan The perfect finishing touch. Skate Cosmopolitan plates complement our faucet collections and will enhance your next bathroom project. They match our Rapid SL frames, Uniset, and all concealed systems, feature Grohe EasyConnect – a single pneumatic hose for fast installation – and can even be retrofitted if required. Fixed vertically or horizontally to suit their surroundings, the majority can also be fitted with Grohe Fresh – our solution for a clean and fresh WC at the push of a button. Our WC plates feature dual-flush actuation of 6 liters and 3 liters – allowing the user to choose how much water to use. For further water saving, all Grohe cisterns can be adjusted to reduce the larger flush volume to 4.5 liters.
