The Spa at 45 Park Lane is a refined subterranean wellness space within the Dorchester Collection's 45 Park Lane in the heart of Mayfair. The spa is home to the longest swimming pool on Park Lane, alongside a hydrotherapy pool, heated pool, separate sauna and steam rooms, and a serene relaxation lounge. A single tranquil treatment room hosts exceptional therapies using ishga marine skincare and Natura Bisse, complemented by transformative advanced facials from skincare specialist Dr Uliana Gout. The state-of-the-art Technogym-equipped gymnasium and bespoke personal training through Intelligent Design — combining strength, calisthenics, and Pilates — make this a holistic destination for fitness alongside relaxation. Hotel guests at 45 Park Lane can also access the full spa and treatment facilities at the adjacent Dorchester Hotel.
