If Tony Stark (Iron Man) were to design his own bathroom, he’d probably come up with a futuristic faucet design like this Koolhaus tap. It allows users to measure and monitor the total water volume used by each bathroom appliance, which will be a good way to educate users to the importance of saving water. With this concept, every appliance in the bathroom will sport its own flow rate device, and will then pass the data of the water usage to the Koolhaus, which will display the water usage information on its built in LCD. If you want more detailed reports, the data can be sent to the user’s computer to help them keep a detailed log and review the past water usage figures.
