The Mark hotel in New York to open an Augustinus Bader spa with a hyperbaric chamber

In late November 2026, the skincare brand Augustinus Bader will open a spa bearing its name inside The Mark hotel, on Madison Avenue in New York’s Upper East Side. Just three treatment rooms, one of them fitted with a hyperbaric chamber: according to the hotel and the brand, the address will favour discretion over size.

Three rooms, one with a hyperbaric chamber

The Mark’s Augustinus Bader spa will not chase sheer scale. It will have three treatment rooms: the first for facials, the second for body treatments, the third fitted with a hyperbaric chamber, a sealed, pressurised enclosure. According to the hotel and the brand, the chamber will be used for recovery after treatments and aesthetic procedures. The opening is slated for late November 2026, with no exact date announced so far.

Red light and compression boots

The menu will combine facials, red light sessions and medical-grade compression boots, inflatable leg sleeves, in an approach that sets out to care for body and mind alike.

The interiors will rely on natural materials and neutral tones, designed with discretion in mind. The full menu and treatment prices have not yet been published: neither the hotel nor the brand has put a dedicated spa page online.

A “cocoon” in the Upper East Side

Charles Rosier, co-founder and CEO of Augustinus Bader, describes the space as a “cocoon” in the Upper East Side, “not just a spa but an experience”. For the hotel, Elon Kenchington, The Mark’s general manager, says every detail has been considered for style, comfort and discretion, to deliver an experience that is “distinctly The Mark”.

A $42 lip balm in every room since 2024

The spa will extend a partnership guests already know. Since July 2024, The Mark has placed a lip balm co-created with Augustinus Bader in every room and suite, tucked into a velvet pouch and sold for $42.

From Hôtel Costes to Madison Avenue

In New York, Augustinus Bader treatments were until now offered in the partner spas of the Four Seasons New York Downtown and the Ritz-Carlton New York, NoMad, the latter with an exclusive version of The Method treatment. At The Mark, the brand will this time have a spa bearing its own name.

The brand’s largest spa is in Paris: the Augustinus Bader Spa at Hôtel Costes, 1,000 m² opened in November 2025. American hotels are betting on branded spas too: in Florida, The Nora hotel is home to the state’s first Sisley spa.

How much is a night at The Mark?

On the official booking engine, the Seventy-Seven King Room (46 m², king-size bed) is listed from $2,403 before tax per night for two on a non-refundable prepaid rate, and at $2,670 before tax on a flexible rate, for the night of 3 to 4 December 2026 (checked on 25/10/2026).

For dining, the hotel relies on The Mark Restaurant by Jean-Georges, which also handles in-room breakfast. For comparison, see our selection of the best hotels in New York, and the future of The Plaza hotel, which will close for at least four years from January 2027.
