Salt Sanctuary

Salt Sanctuary, operating as Sanctuary Spa NYC, is a small treatment studio a few blocks from Union Square, focused on massage therapy and facials rather than a full wet-area spa circuit. The founder, Carmen DeBartolo-Kelly, is a licensed massage therapist and esthetician with a background in luxury spa settings, and treatments are built around her specialties: myofascial release, targeted massage work, and skin-specific facials.

The menu is organized into three groups — facials aimed at cleansing, correcting and hydrating skin; massage therapy for tension relief and mobility; and combo sessions that pair face and body work for people who want both in one visit. Sessions take place in a private studio setting rather than a shared spa floor, which suits solo visitors or couples who want individual attention rather than a communal thermal experience.

This is a reservation-only operation, booked through the studio's online scheduling system, and it's priced in the moderate range for Manhattan day spas. It's open seven days a week, with longer hours Monday through Friday (11am to 8pm) and shorter weekend hours (11am to 5pm on Saturday and Sunday). Some treatments are also bookable as Airbnb Experiences.

Given the studio format and reservation requirement, this isn't a walk-in, day-pass type of spa — it's better suited to people booking a specific massage or facial appointment, whether that's a single treatment or a longer combo session.
