It’s been nearly four years since we first caught wind that The Williamsburg Hotel was planning to install a bar inside of a faux water tower atop its roof, and now that crazy little dream is finally a reality. The Water Tower, as it will henceforth be known, launches tonight atop the hotel’s recently opened pool deck, and a look at the photos indicate this is not the kind of water tower that’s going to give you Legionnaires’ disease.

If you imagined something along the lines of those illicit art parties in a Chelsea water tower, sorry, this place is billing itself as more of a straight-up lounge and nightclub, with regular live acts and DJs. You have to reserve one of the 45-or-so seats by emailing watertower@thewilliamsburghotel.com, and walk-ins are “at the discretion of the door.” If the doorperson doesn’t keep you out, the prices just might: cocktails are $22 to $150 and bottle service starts at $500. Yes, you read that right: there’s a $150 negroni. But, hey, a publicist assures us it’s “really cool” and has truffle-infused Aperol and shaved truffle on top.

As for food, prices range from $20, to $525 for caviar service. We haven’t gotten a look at chef Nic Caicedo’s full menu yet, but we’re told items include a seafood plateau, a bowl of crudite, and a white-truffle grilled cheese on Brooklyn Bread Lab brioche.

I’m just going to quote from the press release here: “The lounge is accessible via a VIP elevator, and colorful murals painted by a local artist line the walls, offering an apt mix of grit and glam that pays homage to the neighborhood’s history.”

You can experience all that grit and glam for yourself Wednesday through Sunday, 10pm to 4am.

Interestingly, thousands of New York City’s actual water towers were built right across the street at the Rosenwach Water Tower Factory. That site was sold in 2009 and is now the site of, you guessed it, another one of Williamsburg’s new hotels, the Hoxton.
