The St. Regis San Francisco has unveiled The Spa at The St. Regis San Francisco, a 9,000-square-foot sanctuary designed by San Francisco-based TEF Design in collaboration with Italian architect Gio Pagani. The new spa occupies the hotel’s fifth and sixth floors and continues the refined aesthetic language first introduced in the hotel’s reimagined indoor pool.

“Our work on the pool and now the spa has been an exciting design journey,” said Paul Cooper, principal of TEF Design. The design team drew inspiration from the nearby San Francisco Museum of Modern Art, echoing its circular forms in architectural motifs and integrating warm materials and soft lighting to create a calm, place-based environment.
Interior finishes emphasize natural textures and tailored detailing: warm wood paneling and bespoke millwork sit alongside textured wallcoverings in rich earth tones, while thoughtful lighting enhances a serene atmosphere. The spa features cedar saunas, eucalyptus steam rooms and a Himalayan salt room, plus separate men’s and women’s relaxation lounges and dressing rooms.

Guests begin their spa journey at the Celebration Bar, where Champagne, fresh-pressed juices, sparkling water, tea and effervescent cocktails are offered. A signature Scent Bar lets guests choose a preferred fragrance that becomes a subtle sensory thread woven through their treatment. Each service includes individualized opening and closing rituals that set the tone and promote realignment and relaxation.
The spa’s treatment menu blends classic and innovative therapies across facials, massages and body treatments. Highlights include Caroline’s Collection, inspired by Caroline Astor and the founding spirit of St. Regis. This elevated set of treatments features the Rose Hydra-Lifting Facial, which combines Hungarian moor mud, a rose-scented gold mask and hyaluronic acid, and the Secrets of the Rose Massage, a richly scented experience using shea butter and the collection’s signature rose fragrance.
A dedicated Wellness Collection focuses on restoring balance and energy. The Circadian Ritual tailors treatments to the time of day, using a blend of massage techniques and essential oils. The Vitality Ritual features invigorating dry brushing, tension-relieving massage and pneumatic compression. The Stillness Ritual emphasizes guided breathing and intentional touch for deep relaxation. Treatments are performed on state-of-the-art Lemi Portofino Evo tables.

The spa is designed to accommodate both individual and shared experiences, offering private treatment suites and elegant spaces suitable for couples, wedding parties and special gatherings. Overall, the design and amenities aim to heighten the St. Regis experience by providing a tranquil, wellness-focused retreat rooted in the character of its San Francisco setting.
