The Rotator is a unique bathtub and shower combination from designer, artist, renowned architect Ron Arad that can transform from bathtub to shower in just one quick rotation on the wall. When the fatter end of the unit is at the bottom, a person can step inside and sit as if they were in a tub. Should the occupant want to take a shower, all he/she has to do is turn the unit “upside-down” and new water (not the water that you bathed in) comes flowing down from the water outlet.
If you’re taking a bath and you’re finished, simply rotate the Rotator sideways and the water drains out of the tub with the help of gravity.
The Rotator made its first appearance in April 2008 at the International Furniture Fair in Milan. The project is a collaboration using duralight material from Teuco.

URINAL FOR THE BLIND!
You’re right, mongchacha, in its bathtub form, it does look kinda like a urinal trough. (Upside-down, it looks like a mind-baffling urinal–shower.)
