An NYPD boss dropped $60,000 to turn an old printing room at Police Headquarters into a Zumba dance studio — in a move that infuriated top cop Bill Bratton, police sources told The Post on Tuesday.

It was just the latest oddball idea from Deputy Commissioner of Personnel Michael Julian, who lost his post in charge of training earlier this year for trying to arm cops with baby oil to deal with protesters and breath mints to clean up their foul language.

To set up the Latin-dance-inspired fitness center, Julian had workers install workout mats and flat-screen TVs in basement room S66, the sources said.

He was so proud of the setup that he gave Bratton a tour — but the commissioner ripped him for blowing the cash.

“That’s not what I wanted!” snapped Bratton, who ordered the equipment torn out and had the room locked, the sources said.

Some cops who work in the building wanted the printing room turned into showering facilities so they wouldn’t have to walk through the building in sweaty workout gear to get cleaned up, the

sources said.

On Tuesday, a sign on the room’s door still read “Printing Section” — and no officers were seen entering or exiting the room.

It’s unclear what the room will be used for in the future or what will happen to the Zumba equipment.

NYPD spokesman Stephen Davis didn’t respond to requests for comment Tuesday.

The dance studio isn’t Julian’s first wacky on-the-job proposal.

In January, he suggested arming cops with breath mints to combat cursing — and had 10,000 individually wrapped candies delivered to headquarters, police sources said at the time.

He said potty-mouthed cops can pop the mints when they feel the need to curse — but they were never used.

He also suggested that officers spray protesters who link arms with baby oil to slide them apart.

His suggestions got him removed from his deputy commissioner of training position, police sources have said.
