Telttasaana Oy is a Finnish manufacturer of handcrafted, portable tent saunas designed to bring an authentic sauna experience to campsites, festivals, boats, cottages, and backyards. The company combines Finnish craftsmanship with practical, durable construction, creating saunas that assemble easily and pack into a compact space for transport. Its tents use fire-retardant, UV-protected fabric and a sturdy stainless-steel frame, making them suitable for varied conditions.

Telttasaana offers complete sauna packages, tents, stoves, foldable wooden benches, and compatible accessories, as well as options for creating a custom setup. The sauna heater, developed in collaboration with Finnish manufacturer Narvi, holds up to 35 kilograms of stones and includes a 10-liter hot-water tank. Bench configurations accommodate four people as standard, with additional seating available for up to six. Designed for both portability and comfort, Telttasaana products aim to deliver generous heat and soft steam without sacrificing convenience. Customers can use a tent sauna temporarily or keep it set up as a backyard or cottage sauna, with the company recommending storage between occasional uses to extend its life.
