Perkūnijos pirties erdvė is a Lithuanian sauna (pirtis) and sauna-master school by a pond in Pajiesys, in the Kaunas district about 15 km south of the city centre. It has two log saunas: the white Perkūnija steam sauna, heated by a wood-fired periodic stove and seating up to 10, and a black smoke sauna (dūminė pirtis) for up to 8. Sauna masters lead 3–4 hour group programmes with whisking, salt and honey (€450 for up to 8), and guests cool off in the pond. Open sauna events are also held.
