Butchers Heat runs a stationary sauna right by the water on Margretheholm harbour near Refshaleøen, open daily to members and with open saunagus sessions several times a week that anyone can book, plus drop-in spots when not sold out. Sessions use pure essential oils, with a dip in the sea between rounds all year round. It also runs the SaunaTruck, a converted military crew car with a wood-burning stove, which pops up around the city and can be hired.
