Social, relaxing and actually really good for you... saunas are replacing the pub as Britons' favourite past-time. They can be found everywhere, from rugged Pembrokeshire coastlines and Scottish islands to inner-city carparks. Some are so traditional, they could have been plucked from Helsinki; others put an innovative - and distinctly British - spin on things, with saunas in repurposed horseboxes and pub backrooms. Many are new, boasting dynamic community events (sweaty yoga, anyone?)

some are as old as our heritage spa towns. This book explores the very best of them.
