A New Lure for Spa Customers? A Salt Cave
Two young women in white chamois robes exited the Himalayan salt sauna at Premier57, a spa in midtown Manhattan, looking rosy and happily spent.
The salt sauna, lined with burnt orange and yellow blocks of sodium chloride, is a popular destination at the spa, where a day pass is $75 and the tagline urges guests to “immerse, indulge, intrigue.”
Options include an infrared lounge, a meditation room, an igloo room, a gold sauna and a clay sauna, “but we have a lot of guests who just come here for the salt room, especially if they have arthritis,” said the spa’s general manager, Ellis Kim. “It’s very good for arthritis and for regulating blood pressure.”
There’s no scientific proof for such claims. And, despite the assertions by Kim and her peers, there is also no proof of the power of salt rooms to bring relief to children with asthma, seniors with chronic obstructive pulmonary disease and everyone in between with stuffy noses or stress, according to Dr. Norman H. Edelman, a senior science adviser at the American Lung Association.
Nonetheless, salt therapy, also known as halotherapy, a venerable treatment in Central Europe and Asia, is now being offered at spas, resorts and stand-alone facilities in the United States in the form of salt beds, salt rooms and salt booths. Floors and walls that are lined with salt blocks and salt crystals, and zero-gravity chairs (recliners designed to relax the back), are the norm. A device known as a halogenerator grinds sodium chloride into a dry aerosol, then disperses it to mimic the microclimate of a salt cave.
Perhaps unsurprisingly, salt spas seem to be sprouting in pockets of the United States that attract the rich. For example, at the Montauk Salt Cave, which opened two years ago in the Hamptons, a session costs $40 for adults. There’s a children’s hour ($40 per child, but adult guardians may enter free) as well as yoga classes and reiki healing amid the Himalayan salt. At the Wellery, a pop-up “wellness center” at Saks Fifth Avenue in Manhattan, weary shoppers can refresh themselves in one of several salt booths (10 minutes for $25) until the end of October.
“The ability to look at salt and see its helpful properties has become a significant part of our business,” said Allan Share, the president of the Spa Industry Association.
In 2012, there were a dozen halotherapy facilities places with halogenerators in North America, according to Leo M. Tonkin, the founder and chief executive of Salt Chamber, a supplier of dry salt therapy equipment, based in Boca Raton, Florida.
“In the last four years, the number has grown to 300 salt chambers,” said Tonkin, who is also the founder of the Salt Therapy Association, a trade group. “There’s been a rapid growth in stand-alone salt facilities and in resorts adding a salt room as an amenity. Day spas have taken an underutilized area and turned it into a salt room, and clubhouses of some high-end residential developments are adding salt rooms.”
Economics are a big driver: A visit to the sauna or steam room is generally included in the basic spa fee at hotels and resorts, but salt rooms often cost extra.
Adding salt therapy to spa services is another moneymaker. At the Four Seasons Resort in Oahu at Ko Olina in Hawaii, 25 minutes in the salt chamber costs $65. The Ha Ritual which involves 50 minutes in that chamber, with guided meditation, a dry salt foot scrub and a massage ??? runs $190.
But there are occasional bargains. At the Breathe Salt Room on Park Avenue in Manhattan, the “salty yoga” classes are $35, the same cost as a standard salt session.
When the Linq Hotel and Casino in Las Vegas opened a new spa two years ago, its two salt caves with halogenerators were a way “for us to differentiate ourselves,” said Joy Matti, Linq’s spa operations manager. “Several spas on the strip have salt rooms, but don’t have halogenerators.”
Linq’s salt caves feature zero-gravity chairs and soft music. Guests who book a spa service for at least $50 are welcome to breathe in the saline air at no additional charge. Otherwise, a 45-minute session runs $40. “We have guests who try it, then come back the next day because they got the best sleep of their lives,” Matti said.
The caves accommodate up to eight people “and are generally booked from 8 a.m. until the last session at 6 p.m.,” she said.
Entrepreneurs have taken note. Tonkin estimates there are 100 stand-alone salt facilities around the country, generally two- or three-room studios that charge $30 to $50 per session, though discount packages and membership arrangements can lower the price considerably.
Many of these spa owners have a side business in salt lamps, bath salts, skin scrubs and Sol??, a concentrated salt solution, to create another revenue stream. To appeal to parents who believe that halotherapy can relieve symptoms of allergies and eczema, some facilities have a dedicated children’s room, with salt on the floor to suggest a sandbox or beach and fish-themed murals.
The decor can be a big part of the lure. Some of the spaces are outfitted to look like Zen relaxation rooms, some resemble caves, and some have backlit blocks of amber and pink salt.
“It’s a great business model because it’s low labor,” Tonkin said. “You don’t need instructors. You don’t have people providing services. And once the facility is built, the operational expenses are low. The only consumable is the sodium chloride that goes into the halogenerator.” A 10-pound bag is $25, he said, and is enough for 200 to 400 sessions in a salt room depending on the size of the room and the length of the session.
