In the heart of Brussels, two iconic names come together to create an unparalleled wellness experience. The Corinthia Grand Hotel Astoria Brussels and Sisley Paris open the doors to an exclusive spa—a first in Belgium—that elevates luxury and relaxation to a new level. This serene sanctuary, designed by ESPA and G.A Group, immerses guests in a tailor-made wellness experience where tranquility and refinement take center stage.
After eight years of restoration, the Corinthia Grand Hotel Astoria, known as ‘Brussels’ Most Fabulous Address,’ reopens its doors, immediately setting a new standard in hospitality. One of its absolute highlights is the Corinthia Spa x Sisley, where luxury and elegance blend effortlessly. Spanning an impressive 1,200 square meters, this spa occupies an entire floor of the five-star hotel, serving as a true oasis of serenity. Accessible to both hotel guests and external visitors, the spa offers a wide selection of Sisley treatments, synonymous with high-end beauty and ultimate care. Every detail is meticulously curated, from the moment you step inside to the deep relaxation that follows—seamlessly combining luxury, comfort, and well-being.
What makes this serene spa truly unique is the story woven into its design. The architects drew inspiration from the rich history of this former palace, which once housed a church where lace makers would pray for the pure perfection of their creations. This heritage is subtly reflected in the spa’s architecture and swimming pool, where marble and white accents evoke the purity of the past. The 17th-century lace patterns, exquisitely incorporated behind the spa reception, further bring a piece of history to life. The Corinthia Spa x Sisley promises an unforgettable sensory retreat where time seems to stand still. With six treatment rooms, a spa suite, relaxation areas, a tea lounge, and a thermal zone—including a sauna, hammam, revitalizing shower, ice fountain, and vitality pool—this spa offers a complete thermal journey. Guests can opt for a short treatment or indulge in a full wellness day, depending on their preferences.
Corinthia Spa x Sisley: an oasis of luxury and serenity
Sisley, the icon of luxurious phyto-cosmetics, finds its home at the Corinthia Grand Hotel Astoria Brussels, bringing its unrivaled expertise in high-end skincare. Corinthia Spa x Sisley offers bespoke treatments that merge exclusive formulas with advanced technologies. From deeply hydrating to anti-aging treatments, every ritual promises pure indulgence, using premium products and unique techniques. But the experience extends beyond the treatment table. The spa concept stimulates all the senses, featuring a subtly scented signature fragrance and soothing music that instantly transport guests into deep relaxation. A perfect harmony between luxury and well-being.
A shared vision of perfection
This collaboration embodies a shared passion for luxury and refinement. Sisley, a pioneer in high-end skincare, and Corinthia, an icon in the world of hospitality, unite their expertise to deliver an unparalleled experience where uncompromising service and exceptional quality converge. Both houses are rooted in visionary family heritage. The d’Ornano family proudly continues Hubert d’Ornano’s legacy in groundbreaking skincare, while the Pisani family has preserved the soul and elegance of Corinthia Hotels since 1962. This natural synergy between beauty and well-being takes shape in the Sisley Spas within Corinthia Hotels in Brussels and New York—an oasis where luxury and relaxation effortlessly intertwine.
Signature treatments in an exceptional setting
The Corinthia Spa x Sisley stands out not only for its luxurious ambiance and top-tier service but also for an exclusive treatment: the Black Rose Facial. This signature Sisley treatment features the precious black rose oil, renowned for its anti-aging and revitalizing properties. To complete the sensory experience, Hannah Van Ongevalle, mixologist at Under The Stairs, has crafted a bespoke mocktail. This alcohol-free cocktail enhances the spa experience, making it even more immersive and long-lasting.
An unparalleled customer experience
The spa is built on four essential pillars: beauty, movement, nutrition, and well-being. Beauty, entrusted to Sisley, offers a holistic approach where a fully immersive sensory experience takes center stage. From a personalized diagnosis to home care with an exclusive product line, everything is tailored to individual needs. This customization ensures not only effective treatments but also lasting satisfaction. The movement pillar is led by Paul Tucker, a former instructor in the Royal Army. He designs personalized programs that enhance physical fitness, reduce stress, and improve cognitive abilities. His approach goes beyond physical training, focusing on stress management, cognitive enhancement, and preventing age-related muscle loss. In terms of nutrition, the Spa Café complements the experience with a healthy and balanced selection. This nutritional philosophy contributes to a holistic wellness journey, including an extensive range of relaxing massages.
An invitation to a sensory journey
The Corinthia Spa x Sisley is more than just a spa—it is a destination in itself. Every treatment, whether a revitalizing express session or an ultimate relaxation ritual, feels like a luxurious escape that recharges both body and mind. This collaboration celebrates the art of refined living, where beauty, comfort, and exclusivity merge into an experience that goes beyond traditional wellness. With this spa concept, Sisley and Corinthia redefine the ultimate luxury experience in Brussels. The spa is now open to visitors. Even non-hotel guests can enjoy one hour of complimentary access to the thermal area with a 90-minute treatment (priced between €180 and €290). For a 60-minute treatment, an additional hour of wellness can be added for a €30 supplement. An exclusive limited-edition membership will soon be launched—stay tuned for more details.
