RUNA is a sauna and outdoor wellness brand focused on portable tent saunas that bring a traditional wood-fired sauna experience to gardens, lakesides, and other locations. Its range includes the CUBE and DOME sauna tents, offered as starter or complete sets, alongside sauna stoves and accessories. Customers can also shop for sauna equipment, clothing, infusions, firewood, ice baths, and related products.

Designed for flexible use, RUNA’s saunas can be packed for transport and are described as quick to assemble, making them suitable for spontaneous sessions as well as more permanent garden use. The brand says its wood stove and adjustable air supply can heat the tent to 90°C or more in around 30 minutes. Customer feedback highlights the straightforward setup, strong heating performance, and the enjoyment of having a private sauna at home or while travelling.

RUNA also provides practical support through setup and stove-use videos, frequently asked questions, a blog, and customer service. The website advertises free shipping within Germany and a 30-day money-back offer.
