Saunas in Iceland
Iceland's wellness tradition is geothermal at its core — the country sits on one of the world's most active volcanic zones, and natural hot springs (hverar) and outdoor hot pools (heitir pottar) have shaped Icelandic bathing culture for centuries. Finnish-style dry saunas exist at most swimming pools and hotels, but Iceland's signature experience is the combination of hot geothermal pools and cold Nordic air, best exemplified by the Blue Lagoon in Reykjanes and the Sky Lagoon in Reykjavik. Traditional communal swimming pools (sundlaugar) are Iceland's most democratic wellness institution — heated year-round by geothermal energy, always free or near-free, and used daily by the entire population.

Sauna culture in Iceland
Icelandic pool culture is unique: swimwear is required (always), showers before entering are mandatory and enforced, and the social ritual happens in the hot pots rather than the sauna. Dry Finnish saunas are quieter add-ons to the main outdoor pool experience. The sauna temperature is often lower than Finnish norms (70–80°C). The real Icelandic contrast is geothermal hot pot (38–42°C) to cold outdoor air (-5 to 5°C in winter).
Frequently asked questions
What is a heitur pottur?
A heitur pottur (hot pot) is a small geothermally heated outdoor pool, typically 38–44°C, found at every Icelandic public swimming pool. They are the social heart of Icelandic pool culture — where conversations happen and news is exchanged.
Is the Blue Lagoon a sauna?
Not technically — it's a geothermal mineral pool complex, not a Finnish-style dry sauna. It does include a sauna element in its premium packages. The Sky Lagoon in Reykjavik offers a more sauna-forward experience with a seven-step ritual including a Finnish sauna.
Do Icelandic public pools have saunas?
Yes — most public sundlaugar include a dry sauna alongside outdoor hot pots and standard pools. Admission is inexpensive (around 1,000–1,500 ISK), making them the best-value sauna experience in Iceland.
