The spa industry is a $17.5 billion business in the U.S., and Las Vegas is well positioned to further accelerate its growth with a burgeoning range of wellness treatments, pampering sessions and beauty boosters delivered in veritable palaces of sensual relaxation. At least 5 percent of Las Vegas’ 40 million guests visited a resort spa at some point during their stay, according to the latest visitor profile reports published by the Las Vegas Convention and Visitors Authority. And there’s room for that percentage to grow.

No other destination offers as many spa choices within such a concentrated geographic area, where creativity in wellness concepts are provided with top standards in training and service. And only in Las Vegas do these services come with fantastical mineral pools or arctic snow chambers or Moroccan hammams.

Following are recommendations you can make to ground your clients’ Las Vegas vacations in pure, wholesome bliss.

SPA ARIA AT ARIA HOTEL & CASINO

Aria’s 80,000-square-foot, two-floor spa offers such luxuries as Ganbanyoku beds, made of primordial silica that helps increase circulation and eliminate toxins. The Shio Salt Room, where guests can listen to theta wave music, features healing salt crystals, salt lamps and zero-gravity loungers. The spa also offers the only-in-Vegas Majestic Canyon Collagen Facial, a 90-minute, $1,000 treatment that uses an age-reversing Valmont cellular mask.

SPA BELLAGIO AT BELLAGIO HOTEL & CASINO

Overlooking the Bellagio’s colorful botanical conservatory, the 65,000-square-foot Spa Bellagio houses 56 treatment rooms and provides such exotic options as the 80-minute Bahia body slimming massage from Brazil. Men’s and women’s areas offer eucalyptus steam rooms, redwood saunas, hot Jacuzzis and cold plunge pools. The Watsu Massage features its own pool chamber with water heated to 94 degrees for optimal muscle relaxation.

SAHRA SPA AND HAMMAM AT THE COSMOPOLITAN

The 50,000-square-foot facility’s hammam features the classic heated slab of marble where guests lie down while being doused with warm water and skin elixirs. Recommend that your clients try the Moroccan Journey treatment, which starts with a detoxing scrub followed by a rhassoul clay body masque and Kalahari melon hydrator. Couples will want to reserve a Sahra Spa penthouse suite, where they can enjoy service in a private treatment area and soak in side-by-side whirlpool tubs.

REVIV AT MGM GRAND

For clients who party hardy or need that extra boost for a big event, such as a wedding, recommend Reviv, a venue in The Underground. It offers vitamin infusions and IV boosters that restore hydration, rebalance metabolism, decrease inflammation and deliver needed energy. Reviv features five proprietary IV Infusions that cover a variety of wellness needs in a 1,270-square-foot space with private and group rooms furnished with large, comfortable body massage chairs.

SPA AT PARK MGM

Unveiled in September, this spa features warm laconicum lounge chairs by the Jacuzzi area, and comfortable, private zero-gravity loungers in the pre- and post-treatment relaxation salon. The spa also offers the option to receive spa services at the French countryside-inspired pool area. Specialties include treatments for athletes like the Athlete’s Massage and the Runner’s Pedicure.

CANYON RANCH SPACLUB AT THE VENETIAN

Measuring more than 134,000 square feet, this day spa may be the world’s largest spa facility and is easily a destination in itself, with more than 100 treatment rooms, where services range from the classic to the exotic. It offers your clients a labyrinth of healing chambers, such as The Igloo, with cool air and three Arctic Mist experiences enhanced by twinkling fiber optics.

Other options include such treatments as Herbal Laconicum using herbal-infused steam, and a classic Finnish Sauna illuminated through refracted crystal. There is also the Salt Grotto, which is bathed in sea air as a fountain bubbles over natural salt rocks.

QUA SPA AT CAESARS PALACE

The 50,000-square-foot spa offers a broad range of services in 51 treatment rooms. Your clients may step into a chamber of reimagined Roman baths with mineralized infinity pools in three temperatures, a waterfall wall and continuously changing phototherapy hues that make the space sparkle.

After their soak, they can chill out in the Arctic Ice Room, which is adjacent to the eucalyptus steam room and cedar sauna. Also, recommend the Mindful Touch, which offers an immersive virtual reality and massage experience.
