A former Equinox member says he was nearly raped in a steam room by a fellow fitness enthusiast — but the luxury gym refused to report the incident to cops or even give him the creep’s name, according to a new lawsuit.

The gym member, Shane Crandall, says Equinox is partly to blame for inciting the attack.

Equinox employees have known for years that their “members were engaging in orgies, indecent exposure, masturbation, sexual assault, sexual harassment and lewd behavior in the men’s steam rooms” — yet ignored it all, according to Crandall’s Manhattan Supreme Court suit.

The Manhattan salesman, 28, says he was in the steam room of the Greenwich Avenue gym on Aug. 9, 2017, when he heard noises coming from a man sitting opposite him.

“When I looked up he was staring at me and masturbating,” Crandall told The Post.

When Crandall tried to leave, the man blocked him.

“As soon as I stood up, he wrapped his legs around mine,” he said. “As that happened, I pulled back and I lost my towel. He took his hand and grabbed my arm. He was trying to press his body against mine. I was screaming. I had to do everything I could to get out of the situation.”

If Crandall had “not been able to free himself from the grasp of the sexual predator, the sexual predator would have raped me,” the suit says.

He immediately told an employee and contacted a regional manager, but the club allegedly did nothing, claiming it was a he-said/he-said situation. When he demanded the man’s name, staffers delayed, claiming they needed permission from their legal department, the suit claims.

He never got the name, but was told the man kept his membership. Crandall didn’t go to police because he didn’t realize he could report it without using the man’s name, he said.

Crandall decided to sue after hearing that similar incidents had happened to other Equinox members.

A spokeswoman for the gym said in a statement, “Equinox takes claims of this nature very seriously and maintains a zero-tolerance policy for any inappropriate behavior in our clubs. In the event that indecent activity is brought to our attention, we take action immediately to identify involved individuals and revoke their memberships.”
