A solid gold toilet

And fully functional.

New York’s Guggenheim museum unveiled its latest installation on Friday – a solid gold toilet titled America.
The toilet, which the Guardian can confirm is fully functioning, is the work of Italian artist Maurizio Cattelan...
Visitors to the museum are able to use the golden toilet in much the same way as they would use a normal toilet. It is located in a standard, pre-existing bathroom on the fourth floor of the museum, a small placard the only indication of its presence...
Nathan Otterson, senior conservator, objects at the Guggenheim, is responsible for maintaining the toilet. He said a cleaning crew will attend to the toilet every 15 minutes... “We would hope no one would try to remove part of the toilet,” Otterson said.
