The Duchess is a functional and stylish shower telephone.
This is one of those projects that is simultaneously intuitive and nonsensical. It’s a shower head made of an old telephone handset, with the temperature control built into the rotary dialer.
There are cold and hot water inputs in the back; the headset output is in the side. The existing perforations in the earpiece serve to let the water escape.
The Duchess is named after the famous Princess telephone, but also invoking “ducha” (Spanish for “shower”).
