Visitors using the restrooms on the 18th floor of exclusive hotel Standard in New York may get a fantastic view through floor-to-ceiling windows – but passersby can’t say the same.

Bathroom users at the Boom Boom Room club at the swanky Standard Hotel in Manhattan are entirely visible to people on the street thanks to the 10-foot windows lining the walls.

And it’s a discovery that has alarmed some unaware toilet-goers as there is no warning sign that their bare behinds will be seen – and sometimes photographed – by strangers below.

“The view outside is exciting, but the view inside is frightening,” visitor David Langdon, 55, from Melbourne, Australia told the New York Daily News.

“I saw people waving at me! Sitting on the royal throne, you don’t expect a public viewing.”

His daughter Belinda Langdon, 24, believed the windows were reflective on the outside, making it impossible for people to see inside the hotel, which is known for its celebrity sightings.

“It’s pretty creepy,” she said.

“The people taking pictures are pervy. You just hope nobody recognizes you on the street.”

The windows are visible to tourists visiting the High Line park, a public area which is built on an historic freight rail line elevated above the streets on Manhattan’s Meatpacking District.

Rows of bathrooms line the walls of the building with users sitting close enough to the windows for passersby to see them sitting and relieving themselves.

There are no curtains or blinds on the windows for the more bashful customers wishing to avoid giving jaw-dropping views to the tourists below.

Among the toilet users are people visiting the club and a rooftop lounge at the hotel, which is favored by celebrities including Leonardo DiCaprio and Cameron Diaz.

But some patrons said they do not care about their very public display, with one man even waving to people below as he used the toilet.

“Who cares? So people know you have to pee?” Florentina Ballesteros, 26, added to the Daily News.

“The view was wonderful both ways!”

Managers at the Standard refused to comment on the bathrooms. It is not the first time that the Standard has hit the headlines for its semi-clothed antics.

In 2009 people walking along the High Line Park were treated to free peep shows from guests – including couples having sex and porn films being recorded – in the rooms above.

One shopworker in the area said she saw “a naked girl jumping up and down on a trampoline right in front of the window”, while others were shocked to see men pleasuring themselves.

In 2008, the hotel won an award from the Municipal Arts Society of New York for best new building erected that year.
