Coming to Kaupinoja sauna
Kaupinoja sauna is situated by lake Näsijärvi close to the UKK-Institute. There has been a sauna on the spot since 1977, but the sauna has gone through several transformations and renovations. In 25.4.2010 the sauna was reopened after a thorough renovation due to the fire in 15.11.2008 which completely destroyed the sauna proper. The building is property of the city of Tampere, but the sauna is maintained by the winterswimming association Tampereen Talviuimarit ry.
