Disbelief: Tourists point at the shocking views of people using bathrooms in the hotel above
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 favoured by celebrities including Leonardo DiCaprio and Cameron Diaz.

Watch out! There are no signs in the bathrooms warning patrons that they can be seen from below
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.
