The heat is on as Britain’s boom in seaside saunas stirs up some local sweat

Hot boxes are popping up on the coast, as well as beside lakes and rivers, but not everyone is happy about the trend

Seaside saunas were just a wisp of a dream until 2018. Now anyone walking along a beach at one of the UK’s main resorts is likely to come across a converted horse box offering heat and steam as a respite from bleak skies and icy winds.

There are now 70 such saunas operating in the UK according to the British Sauna Society, mostly at beaches or lakes, fuelled by the growth in wild swimming and healthy living.
