Well, aside from the cool modern style of the Hansa Canyon faucet, Hansa has been a frontliner of the current trend of LED lighting incorporated into everything, including faucets.
We just installed this in a client's bathroom. It features electronic controls, and temperature-sensitive LED lights.
Red = Hot
Blue = Cold
And Purple = Somewhere in the middle
I'm excited to post more (and better) photos of this project once it's finished!
