Collection: Spas in London

Most of London keeps its best spas underground. Beneath Mayfair, Knightsbridge and Whitehall there are pools lit by a single blade of skylight, gilded mosaic chambers and thermal suites cut into old foundations, and almost none of it shows from the street. One sits up on a roof instead, glazed to Hyde Park. What separates them is temperament, some quiet and ceremonial, others closer to a clinic.
