Augustinus Bader Spa at the Hotel Costes: Customized Treatments and an Exclusive Pool Lounge in Paris

Paris now has a new sanctuary for indulgence: the Augustinus Bader Spa has opened its doors at the Costes, the iconic luxury hotel located on Rue Castiglione (Paris 1st). Spanning 1,000 square meters of wellness, it blends cutting-edge science with refined luxury. Every detail has been carefully curated to elevate the experience: from smoked oak and sculptural marble to emerald glass paste, the Studio Liaigre creates an upscale intimacy, subtly illuminated by Arnold Chan and enveloped in the signature scents and sounds that define this unique space.

The spa takes a comprehensive approach with eight bespoke treatment rooms: skin analysis, facials, body treatments, private sessions, couples experiences with a hammam, Pilates on reformer beds, and manicure-pedicure. Gold-toned bronze fixtures, Dolby Atmos sound technology, and custom smart automation create a timeless escape in every visit. Hands and feet are pampered with Révérence de Bastien products, enhanced by Kure Bazaar nail polishes, while the Bewei radiofrequency device and Evelab’s 3D analysis deliver instant, personalized results.

The product range, available on-site—including creams, serums, and elixirs—extends the experience, helping you maintain that spa-fresh glow at home.

For relaxation, the pool lounge, a delightful highlight of Costes, offers a tranquil escape for lounging and daydreaming from 8 a.m. to midnight. Meanwhile, customized treatments — including manicures, pedicures, facials, and body care — are available daily from 10 a.m. to 8 p.m.

Here, luxury spa experiences blend seamlessly with science, transforming each treatment room into a chic invitation to indulge and take care of yourself… Parisian style.
