I've never viewed a bathtub as anything other than utilitarian, but it seems Russian designer Alexander Zhukovsky has other ideas.
We're not talking about your traditional marble tub, affixed to the floor, suited to your regular Joe Blow here. Oh no, no - this is a hanging, clear glass sphere that acts as both bath and shower, with settings for you to alter its internal temperature, humidity, light, sounds and smell. It even simulates rain. How fancy! I mean, who doesn't want to expose their bits while trying to float in a glass bubble, smack-bang in the middle of the lounge room?
There's more at the link. You can see a more technical diagram of his BathSphere here.
A perspex bath globe, suspended from the ceiling. Hmm . . . I wonder what it would do in an earthquake? It might turn out to be a wild (and wet) ride!
