- 💷 £700,000 · five months of work, completed in September 2026
- 🧘 Reformer at One Spa · dedicated studio, six Italian-made Technogym machines, small group classes
- ♨️ Rasul Mud Bothy · self-service mud thermal ritual, new poolside sauna, cold room
- 💅 OPI and Skin Rocks · new NOW nail bar and treatments from Caroline Hirons’ brand
One Spa, the wellness area at the Sheraton Grand Hotel & Spa Edinburgh, known for its heated rooftop pool facing the castle, has emerged from five months of renovations. £700,000 has been invested in a Reformer Pilates studio, a new thermal ritual, a poolside sauna and a fully refitted gym.
Six Reformers in a dedicated studio
The centrepiece is Reformer at One Spa, a studio built for six Italian-made Technogym machines, with a class programme led by Edinburgh Pilates instructors. Demand for this low-impact discipline, which focuses on core strength, has exploded in British cities; it is the spa’s largest expansion in years, according to its director Fiona Young.
The rest of the gym follows suit: connected Technogym equipment, on-screen virtual classes and a functional training floor.
◆ One Spa after the works
Mud, cold and steam
The thermal journey gains a Rasul Mud Bothy, a cabin where guests apply mineral muds themselves before a steam shower, to be shared by two or more. A sauna has been built by the indoor pool, a cold room allows for hot-cold alternation, the hammam has been enlarged and a foam wall installed. The rooftop hydropool, with its view of the castle, remains the house’s star attraction.
OPI at the nail bar, Skin Rocks in the cabins
The NOW nail bar reopens with OPI as a partner. Facial treatments now feature Skin Rocks, the brand by Briton Caroline Hirons, one of the most followed voices in skincare across the Channel. General Manager Martijn Zengerink presents the whole as a response to guests who expect a spa to support movement and recovery, not just relaxation.
Scotland’s most awarded spa
Voted Scotland’s best spa in 2023 and 2024, One Spa is this year shortlisted in two categories of the Good Spa Guide Awards 2026. This work is timely: the Sheraton Grand, at Festival Square, remains one of the few hotels in central Edinburgh to have a true urban spa, with an outdoor rooftop pool.
