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.
