The Langley Spa is an exceptional luxury wellness destination set within a grand 18th-century Palladian mansion surrounded by 150 acres of Capability Brown-designed parkland in Buckinghamshire, and it holds the distinction of being the only full-service Sisley Paris spa in the United Kingdom. Spanning 1,600 square metres, the spa features a 16.5-metre infinity-edge indoor pool, a Himalayan salt sauna, a brine-infused steam room, a hammam, and a fully equipped gym. A dedicated female-only area offers heated loungers, a saunarium, a rose quartz steam room, a vitality pool, and a private hammam. The VIP suite adds a juniper-infused sauna, amethyst steam room, private butler service, and champagne. Five treatment rooms and a private suite deliver botanically inspired facials, body scrubs, and wraps using Sisley, Sultane de Saba, and Gentleman's Tonic products, while an advanced fitness suite provides bespoke wellness programmes in partnership with trainer Matt Roberts.
