Have the Hamptons without leaving Manhattan. 

From the front, this historic Greek Revival townhouse looks posh and buttoned up.

But, like a mullet, it’s all business in the front — and party in the back.

Indeed, beyond the unassuming brick facade of this tony 232 W. 15th St. property, the interior is thoroughly modern and features an entire floor dedicated to an indoor swimming pool. 

“Not only does the home have a full-size saltwater pool, it has a sauna and one of the most serene backyards in Chelsea,” Benjamin P. Dixon, who shares the listing with fellow Douglas Elliman agent Christian Poppell, told The Post. “It is living in your own personal Zen oasis.”

The unique urban amenity has resulted in real-estate blog Curbed once calling the property “Chelsea’s strangest house.”

Despite its quirky crown, the home has been on and off the market since 2011 — finally selling last month for $9.5 million. 

Its new owner is now looking to rent the three-story space for a pretty penny, namely $33,000 a month. 

“Swim year-round in a dramatic 30’ long, 8’ deep heated saltwater pool beneath a double height solarium,” its listing boasts, adding that, in addition to the defining water feature, the triplex also has a double-height solarium, a poolside wet bar, self-irrigated planters throughout, four working fireplaces and a primary suite with a free-standing tub overlooking the garden. 

In all, there are seven bedrooms and 3.5 baths spread over 3,000 square feet. 

Also, there’s a waterfall that cascades into the pool from the second story. 

“You feel like you’re on a permanent holiday,” former owner Evelyn McMurray Van-Zeller told the Wall Street Journal in 2011 of living at the address. “There’s almost no reason to leave the house [with] the pool, the sauna [and] the gym.”

The pool, that article noted, was installed in 1975.
