Sauna Wisła is a floating Finnish sauna on a barge in Port Czerniakowski, reached by a gangway from the car park at Czerniakowska 136a. The cabin holds up to eight people at 75–100°C, and guests cool off in a cold-water tub and rest on jetties and terraces overlooking the port. It runs 24 hours a day with slot prices that vary by day and hour, sells exclusive slots for private groups, holds family sessions and senior hours, and offers free sessions secured by a 29 zł deposit.
