Destinations: Asia & The Pacific

As for proper behaviour, common sense and good manners should stand you in good stead. If the room is silent, be silent. If it’s sociable, join in.

Still, sceptics should know that private, luxurious alternatives exist. Thanks to hotel spas that balance authenticity with customer comfort, these are more prevalent than ever before.

Whether you’re looking for a traditional experience or one that’s personal and private, these three different bathing cultures will flood you with desire to dip in soothing H₂0.

The Roman Empire is long gone, but European aristocrats have enjoyed the privilege of wallowing in the restorative waters of thermal springs and the sea for centuries. You too can do as the Romans did – in Paris, perhaps, or a little old spot near Prague.

The Czech spa town of Karlovy Vary has been a popular resort since medieval times. Guests enjoy à la carte thermal soaks or stays at “spa houses,” where prescribed treatments are given in various vitality pools, saunas, salt rooms and caldaria (hot baths).

The new AVA spa at Four Seasons Hotel Prague – a two-hour drive from Karlovy Vary – also centres on modern versions of historical practices, says Spa Manager Claudia Santos. The name AVA, she adds, is Celtic for “water.”

Here, guests may soak in a private bathtub – overlooking Prague Castle – in the spa’s Couple’s Suite. To fill that tub, they may choose either mineral-rich water like the “miracle mineral water” of Karlovy Vary, sulphurous water or water with high iron content.

Plunging into a hot spring isn’t the only way to go, especially if you’re fond of salt water. Therapeutic sea bathing got its start in the late 16^th century, when various nobles such as King Henry III began vacationing on the Bretagne coast in northern France. In the 1800s, Empress Eugenie brought her court to summer in Biarritz, where they would take their dips, at prescribed times, in accordance with medical mediation.

Almost as early, scientific studies began to document its effectiveness at everything from accelerating the elimination of toxins to replenishing depleted calcium and phosphorus in the bones. And nearly everyone feels better after a swim in the sea.

The Spa at Four Seasons Hotel George V, Paris, channels this healing power by incorporating algae and other sea minerals into its body treatments. This way you can time your own tides.

In the Roman Empire, public bathing was not just for rinsing off the grit but also for socializing and conducting business. Later, in the Ottoman Empire, this excellent idea gave rise to the hammam, where bathing rituals are used to celebrate major life events like weddings and births.

Today, hammams can be enormous and bustling. Almost always, they’re separated by gender. When trying out a traditional hammam, it’s best to bring your own supply of Moroccan black soap, an olive-based, spreadable soap that leaves skin unbelievably hydrated. But most locations sell samples, along with sandals and towels.

At the centre is a giant marble slab, where guests recline and acclimate to dry or steamy heat, depending on the hammam. Meanwhile, they can look forward to an intense, full body scrub, which leaves skin feeling baby-soft. Traditionally, guests complete the scrubs themselves, or with help from friends or family.

“The hammam ritual is a venerated Moroccan tradition which has endured for centuries,” says Ouafaa Aboudya, the spa manager at Four Seasons Resort Marrakech. The Resort’s spa offers a luxurious, private version of the hammam and its signature scrubs designed for those who desire a calmer, less social experience.

The Resort’s ritual is performed in a steamy marble room full of Arabian lanterns, carvings and mosaics: A therapist gives guests the traditional black soap treatment with a mildly exfoliating kessa glove before applying a full body wrap of ghassoul (a naturally cosmetic clay) and argan oil, along with amber oil, sugar and beeswax.

Guests at The Spa at Four Seasons Hotel Istanbul at the Bosphorus can enjoy a similar experience. Unlike the lively traditional hammams, this one is fully private. Guests can savour exclusive moments by themselves, with a partner or with several friends. Here, therapists apply the soap with a kessa glove and then treat guests to a plush foam massage.

Japanese onsen: Soaking in peace

The Japanese have relished silent, meditative soaking in the abundant natural hot springs of their volcanic country for millennia. Dogo Onsen, for instance, is believed to be 3,000 years old.

The heat, the tranquillity and the scenery give rise to a sense of awe at the natural world. But onsen (a word for either a hot spring or an associated resort), have also served as important social levellers; historical texts describe springs as welcoming peasants, emperors and gods.

Traditionally, etiquette is quite strict – for instance, tattoos are still banned from many public onsen, due to their association with criminal behaviour in Japan.

“Many people do not have a good impression of tattoos,” explains Mami Kumoda, the Guest Experience Manager at Four Seasons Hotel Tokyo at Marunouchi. “They can intimidate people. Visitors might be unable to relax, which unfortunately defeats the purpose of visiting an onsen.”

Before entering a public onsen, guests are required to sit on one of its stools, rinse off and shampoo their hair. During this process, Kumoda says, it’s important to enjoy the moment quietly, without disturbing others. It’s also important to wash away all shampoo before entering any onsen’s waters.

“Onsen and their surroundings should remain as untouched as much as possible,” she says. “Hot spring water should only be from nature. Surroundings, minerals, temperature and colour all count toward the feeling of being one with nature at the onsen.”

Despite being indoors, the onsen at the Hotel feels as if it’s a part of the natural world. “Natural light floods a dimly lit area in both the men’s and women’s onsen,” she says. “Guests are able to escape here from the realities of their busy day-to-day lives. It allows anyone a moment to breathe and mediate. You won’t get distracted by anything here.”

Ultimately, the onsen at the Hotel enhances the age-old tradition of hadaka no tsukiai (socializing while naked). “It’s not easy to become open-minded in many situations,” Kumoda says. “The atmosphere of this particular onsen changes that.”
