Compare sauna access at gyms in Reykjavík, Kópavogur and Hafnarfjörður.
Icelandic gyms that confirm a sauna are concentrated in Reykjavík, Kópavogur and Hafnarfjörður, with World Class branches among them, and a few beyond the capital such as Patreksfjörður and Seltjarnarnes.
The sauna may belong to the gym's changing rooms or to an adjoining public pool, which changes the hours and the price. Check whether your entry includes it, whether there is a steam bath as well and whether the pool's shower rules apply before you go in.
