‘Animals’ trash Hamps loo

TALK about s - - tty! A drunken partygoer (or partygoers) vandalized the bathroom at the Main Room nightclub in Southampton on Saturday, causing $50,000 in damages. “They bashed everything,” distraught owner

Zach Erdem tells Page Six. “They pulled out the urinal water line. It’s almost an entire wall. It’s very upsetting. Why would you do that?” Video seen by Page Six shows six massive holes in the walls all around the bathroom — plus a urinal ripped out. The perpetrators hit when the club was busy.

“No one knows who it was,” Erdem says. “To pull that out you have to be a powerful person. They are animals. It was scary.”

We’re told there were no plumbers available over the holiday weekend, but luckily there was another functional bathroom. Erdem said the damage will cost him $50,000 to fix, and he plans to keep security guards outside the bathrooms to make sure culprits don’t strike again.

“Every single person in and out, he will check the door to check that everything is OK,” Erdem says. He is also offering a $1,000 reward and free meals to anyone who tips him to the identity of the bathroom bashers.

Over at Erdem’s other spot Blu Mar, things were calmer. Jason Binn’s DuJour Media hosted a bash honoring Katie Couric and Al Sharpton.

But at his restaurant 75 Main, there were some impatient customers due to Erdem’s celebrity since his Discovery+ reality show, “Serving the Hamptons,” premiered this year. “You couldn’t walk 2 feet without customers taking selfies with him and his staff from 75 Main Street,” said a spy. “It happened so much that food was delayed by an hour at some patrons’ tables. People were pretty angry.”

Meanwhile, over at Michael Pitsinos’ Naia restaurant at the Capri hotel, John Catsimatidis showed off his 50-pound weight loss. The billionaire was spotted hosting a breakfast with former Gov. David Paterson and Suffolk County Police Commissioner and former NYPD big Rodney Harrison.
