The Bath House at the Royal Crescent Hotel
A classic hotel with a twist, this 'beautiful period property, in Bath's most exclusive Georgian crescent, is home to a serene spa with a rather Scandinavian feel', says Anna. 'The traditional woodrich spa is the essence of tranquillity, from the lavender-lined path that leads you to the entrance to the seductively steamy relaxation pool.'
