Mayor Bloomberg has shelled out more then $13,000 for a hand-made copper bathtub made at a historic workshop in northern France.

Craftsmen in Normandy spent 250 hours making the luxury tub to the billionaire’s exact specifications, according to the owner of the 200-year-old copper workshop.

The mayor is currently renovating his five-story Upper East Side town house at a reported cost of $1.7 million.
