Most health spas are flexible and offer a variety of packages, particularly if the spa is attached to a hotel.
It is possible to choose an individual treatment, a package of treatments, a half-day, an evening, two-day or longer sojourn.
At The Bath House, at the Royal Crescent Hotel in Bath, a two-day break includes use of their spa facilities, plus dinner, bed and breakfast for around £300 per person.
