Anchored on the Spree, opposite Spreepark in Friedrichshain, is one of the city's most extraordinary sauna experiences: a houseboat with its own floating Banya, accessible only by pedal boat.
Saunainsel Berlin: Sauna on the Water
Batuga’s Saunainsel (Sauna Island) is a floating gem on the Spree, opposite Spreepark. The facility consists of a fully equipped houseboat and a separate floating sauna. This sounds like more than it initially suggests. In fact, Saunainsel Berlin is one of the most extraordinary sauna experiences the city has to offer.
Access is by pedal boat, which is available free of charge for the entire stay. Upon arrival, you leave Berlin behind on the shore. The facility offers a 95-degree hot Banya sauna, a hot tub, a relaxation room with a fireplace, a spacious sundeck with a grill and fire pit, as well as a kitchen, shower, toilet, and a large bed. The sauna design is based less on Finnish and more on the Russian Banya tradition. If you want to cool down after sweating, jump straight into the Spree. It’s as simple as it is effective.
Saunainsel Berlin: Rent Privately or Join Open Sessions
Whether alone, as a couple, or as a group, the Saunainsel offers the perfect location for a break on the water. Generally, events for up to 10 people are offered. Furthermore, the island can also be rented privately, for example, for birthdays, bachelor parties, or company events. For private events and overnight stays, the island can be booked for up to 20 people. Generally, two sessions take place, in the afternoon and evening, and sometimes in the morning on weekends. Long opening hours until 23:00 also allow for a relaxed end to the day at a later hour. So, if you’re looking for a Berlin sauna experience that feels far removed from typical sauna landscapes and wellness hustle and bustle, you’ll find exactly what you’re looking for here.
