Located at the Sheraton Grand Hotel, Europe's most advanced city spa, One Spa, opened in September 2001. The six storey building, with three split levels of spa, the first of its kind in Scotland, houses a wide range of facilities and treatments, many unique to the spa and currently not available within the UK. The most signature feature of this Spa is the Roof top Hydropool. This Spa has every type of water and thermal experience you can imagine.
