Why salt? All pools require sanitization but using chlorine has gone out of favor as it is deemed overly harsh on swimmers’ skin, eyes, hair, lungs, and swimsuits. Take this with a grain of salt (pun intended!), but saltwater enthusiasts claim the benefits of saltwater over traditionally chlorinated water range from being gentler on your eyes, hair, and skin to making the water feel softer to more dramatic claims of having anti-stress properties and being better for your joints. Whatever the benefits, a saltwater pool isn’t nearly as salty as the oceans, as it contains 10 times less salt (with 3,000 parts per million salinity in a saltwater pool and 35,000 ppm in the ocean).

Ahead, CityRealty rounded up 12 residential developments with saltwater pools to help New Yorkers embrace that island life.

1. The Kent

The Upper East Side luxury residence The Kent has a stunning 55-foot saltwater pool with a sophisticated geometric design that echoes the Art Deco theme in the rest of the building. The pool features a backlit glass sculptural wall and custom teak millwork. To add to the experience, the heated saltwater pool is paired with Finnish saunas for the ultimate spa-like experience.

2. 40 Bleecker

40 Bleecker is home to a custom-crafted saltwater pool. The 58-foot pool is clad with mosaic tiling, perfect to admire while doing the backstroke. This one-of-a-kind pool marries warm neutral colors and stone materials throughout.

3. Waterline Square

Developed by GID Development Group, Waterline Square is an iconic collection of three residential buildings on one of the last remaining waterfront development sites on Manhattan's Upper West Side. It surrounds a three-acre park and all three buildings share a massive amenities package spanning 100,000 square feet. One striking amenity of the residents’ Waterline Club is their 25-meter, three-lane saltwater lap pool brightly lit with a unique skylight and inset ambiance lighting.

Beyond the outrageous 360-degree views, the pool is surrounded by lounge chairs, al fresco dining areas, and an outdoor movie screening space. And, even better, in the winter months, Brooklyn Point will also offer a 65-foot indoor saltwater swimming pool in the spa.
