Icelandic swimming pool culture: the sundlaug

Ask Icelanders where they truly relax and most will point you not to a famous lagoon but to the local swimming pool, the sundlaug. Almost every town has one, heated by geothermal water, open early until late, and busy in every season. It is the village square, the gym, the spa and the social club all at once, and it is one of the warmest windows into everyday Icelandic life.

More than a swim

A typical sundlaug has a lap pool, one or more hot pots at different temperatures, often a steam room or a small cold tub, and sometimes a water slide for the children. People come to swim a few lengths, yes, but mostly they come to sit in the hot pots and talk. News is shared, friendships are kept up, and visitors are welcomed into the conversation. In Reykjavik the grand old Laugardalslaug is the largest and liveliest, while the geothermal beach at Nauthólsvík brings the same spirit to the seaside.

The one rule everyone follows

There is a single piece of etiquette that matters more than any other: you shower thoroughly without a swimsuit before you enter the water. Icelandic pools use very little chlorine because everyone rinses well first, so this simple habit keeps the water clean and clear for all. Staff are happy to point you to the showers, and once you understand the reason it feels completely natural. We cover the whole routine in your first Icelandic bath.

The hot pot is the heart of it

The small, hot pools, the hot pots, are where the magic happens. They are kept at a range of temperatures, so you can move from a gentle warm pot to a hotter one and back. This is where locals linger longest, often for the better part of an hour. To learn how the hot pot tradition grew and how to enjoy one, read our guide to the Icelandic hot pot.

The lagoons are the occasion; the sundlaug is the rhythm of the week.

Year round, in every weather

Part of the joy is that Icelanders go in all conditions. Sitting in a hot pot while snow falls softly, or steam rises into a frosty morning, is a small everyday wonder. Because the water is geothermal and the pools are outdoors, winter is one of the loveliest times to go, with the heat all the more welcome against the cold air.

How to enjoy it as a visitor

• Bring a swimsuit and towel, or rent them at larger pools.
• Shower first without your swimsuit, the single most important step.
• Pay the modest entry at the desk; municipal pools are wonderful value.
• Start in a warm pot and work up to the hotter ones as you settle.
• Leave your phone in the locker and let yourself slow down.
• Say hello. A friendly word in the hot pot is how locals meet, and visitors are welcome.
