The Gainsborough Bath Spa.

The Gainsborough Bath Spa stands out as the only hotel in the UK with direct access to Bath’s naturally heated, mineral-rich thermal waters. Occupying two Grade II-listed buildings that once served as hospitals, the property balances its Georgian and Victorian heritage with a polished, contemporary interior designed by Champalimaud. The centerpiece is the Spa Village, where guests follow a circuit through thermal pools, an ice alcove, and an aromatherapy bar under a glass-roofed atrium. For those seeking total immersion, the spa suites feature roll-top bathtubs with a third tap that pours the thermal water directly into the room. The atmosphere is refined and hushed, extending to the Canvas Room for afternoon tea and a restaurant that emphasizes seasonal British ingredients.
