Litla Sauna Húsið is a small seaside sauna on Kársnes in Kópavogur, looking out over Reykjavík and the Atlantic, founded in autumn 2024. Its sessions are gusur led by trained gusumeistarar who control heat and humidity, use essential oils and fan hot air through the room. A place in a public session costs 5,500 ISK, with 5-, 10- and 20-visit cards; private group sessions can be arranged, and some sessions run at Vífilsstaðavatn.
