After 99 years, its first spa.

The Mark Hotel spa is, strictly speaking, a new idea for an old building. The hotel at Madison Avenue and East 77th Street opened in September 1927 as the Hyde Park Hotel, an apartment hotel designed by the firm Schwartz & Gross. It became The Mark in 1988, and in 2009 the French designer Jacques Grange redesigned the interiors that define it today. In all that time it has never had a spa.

That changes this month. The hotel is opening The Mark Wellness & Longevity Spa by Augustinus Bader, a three-room spa run with the German skincare brand. The hotel announced it in late October 2026 and said it would open in November, without naming a day.

The Mark already has a strong reputation, so a spa is a small addition. What’s interesting is the kind of spa it chose. Rather than adding the usual hotel spa of pools and relaxation lounges, it has opened something closer to a skin and longevity studio.

The idea

Augustinus Bader is best known for its creams, which are built on a patented ingredient complex the brand calls TFC8. The company says the technology comes from more than 35 years of research by Professor Augustinus Bader into how cells communicate. The brand already offers treatments in hotel spas around the world, and it opened its first standalone spa and shop in London. According to the announcement, The Mark is its first dedicated hotel spa in the United States.

The name says a lot about the idea. Calling it a “wellness and longevity” spa follows a clear trend in Manhattan hospitality. Guests increasingly want treatments with a technical story behind them, not only a massage and a robe. In the announcement, the hotel says some of the wellness offerings have been studied for their effects on selected health biomarkers. That claim comes from the hotel, and we would like to see the details before repeating it with any confidence.

A hotel that waited almost a century for a spa has opened a studio, not a pool hall.

What you actually do at The Mark Hotel spa

Signature Augustinus Bader facials are the centre of the menu. According to the hotel, the facials use several technologies:

• precision nano-channeling
• microcurrent
• Biosonix ultrasound
• full-spectrum LED
• ionised oxygen therapy

Protocols are personalised. When Time Out New York reported the opening on 27 October 2026, the full treatment menu and prices had not been announced. We will add them once the hotel publishes them.

Before the spa, The Mark’s wellness offering came to your room. Its wellness page still lists in-room massage, including a lymphatic treatment pitched at guests recovering from long flights, plus personal training and IV drips. Facials have been offered with Dr. Barbara Sturm. The hotel also has a 24-hour Technogym fitness centre and an in-house personal trainer. Its penthouse, which the hotel describes as the largest hotel penthouse suite in North America, has its own outdoor cold plunge and private gym.

The space

There are only three treatment rooms. That is small for a hotel spa and very normal for the Upper East Side, where the best facialists often work from a single room above a shop. The hotel has not said which floor the spa is on, how large it is, or who designed it. Given how carefully The Mark has protected Grange’s interiors, including during a recent restoration of its rooms and suites, we expect the spa to be quiet and fitted out to a high standard rather than built around a wellness concept. That’s our guess, though, and the hotel hasn’t confirmed it.

Who it’s for

The spa has two audiences. The first is hotel guests who want a serious facial without leaving the building. The second is the people who live nearby. The Mark says New Yorkers who are not staying at the hotel can book too, which makes this a neighbourhood spa as much as a hotel amenity. With three rooms and a well-known name on the door, expect appointments to fill up early.

Good to know

• Where: The Mark, at the corner of Madison Avenue and East 77th Street, on the Upper East Side.
• When: Opening November 2026. The hotel had not given an exact date when it made the announcement.
• Who can book: Hotel guests and non-guests.
• How to book: Through The Mark’s official website or the hotel’s concierge. Treatment prices had not been published when this article went out.
• Nearby: Central Park and the Metropolitan Museum of Art are a short walk west, so you can combine a facial with a walk.

Why it matters for New York

New York has plenty of hotel spas, but very few are run with a brand that has its own research behind it. The Mark’s choice shows where hotel wellness in the city is going: smaller spaces, more specific treatments, and a clear story about longevity. Clubs and hotels that plan to follow should do the same thing The Mark did and keep the spa small and focused.
