The Royal Mineral Water Hospital in Bath is to be transformed into a luxury hotel following an extensive refurbishment.
Speaking on behalf of the Fragrance Group, Martin Rogers of Global Hotels & Leisure Consultancy, said: "The Fragrance Group has a track record of breathing new life into historic city buildings that are no longer required for their original purpose.
"Since the group acquired the Royal Mineral Water Hospital in Upper Borough Walls, Bath, it has appointed leading architects from the city's Stride Treglown practice with a brief to sensitively develop plans for a four-star hotel which respects and honours the original building.
"They have been working with other leading consultants and liaising closely with the conservation team from Bath and North East Somerset Council and with Historic England, who have both offered expert advice."
Details of plans for the new hotel will be made public in the autumn.
Fragrance Group now owns six operational hotels in the UK, including the Imperial in Blackpool, the Townhouse in Manchester and the Crown hotel in Harrogate. It is also the owner of a further six hotel development projects, including the redevelopment of the Grade II*-listed former city council headquarters in Liverpool into "a high quality hotel".
