Fiorst Opens Wood-Fired Nordic Sauna and Cold Plunge at Schuylkill Center

Fiorst has launched a mobile, wood-fired Nordic sauna paired with a cold plunge on the grounds of the Schuylkill Center for Environmental Education, bringing a guided hot-and-cold bathing experience to the preserve at 8480 Hagy’s Mill Road in Northwest Philadelphia. The glass-walled sauna overlooks a snowy field and woods and is available for public sessions on weekends from 9 a.m. to 5 p.m., with bookings handled through Fiorst’s website and currently limited to one week in advance.

Sessions run 90 minutes and cost $75 for a single person. Guests can add a friend for $25, and private bookings for groups of up to 16 are available for $600. The center is expecting Valentine’s Day weekend to book quickly, reflecting solid interest driven in part by social media views since the installation’s opening weekend.

The Fiorst setup is presented as an immersive outdoor ritual. Fiorst’s website frames the experience this way: “We believe saunas belong outdoors. Located in unique outdoor locations our sessions embrace the elements, you’ll feel the bite of the winter air and hear the crackle of the fire. It is a raw, real, visceral experience.” The company also emphasizes a fully hosted model: “Every session is led by a trained host who manages the environment and the timing. We feed the fires and environment, allowing you to focus entirely on enjoying the experience.” Fiorst further describes its heat source: “This isn’t the dry electric heat you find at the gym. We use a traditional external-fed wood-burning stove to maintain a deep penetrating heat. Combined with hot stones, steam, and aromatherapy, it delivers a primitive intense heat that electric heaters simply can’t match.”

Erin Mooney, executive director of the Schuylkill Center for Environmental Education, tested the contrast herself during opening weekend and recalled the extreme cold and the lure of the hot-cold practice: “I never thought that I would find myself in a bathing suit laying down in the snow on a 15-degree day, and I found myself doing that at the Schuylkill Center.” Mooney said the partnership grew from a desire to keep the preserve lively through winter and to introduce visitors to the Nordic tradition of alternating intense heat and cold.

The install mirrors Fiorst’s Riverside location model at 32 River Road in Conshohocken, where Fiorst advises guests to rinse off sweat before entering the cold plunge. Restroom facilities are available for changing, though Fiorst recommends arriving ready to sweat. The company allows snacks and drinks by the firepit but asks that no food or beverages go inside the sauna and that guests pack out their trash. Fiorst is exploring additional locations and invites venue owners to contact team@fiorst.com about partnerships.

Practical takeaways for visitors: book through Fiorst’s site up to one week ahead, arrive prepared to change quickly, expect a hosted experience focused on wood-fired heat and timed plunges, and heed onsite guidance about rinsing and firepit use. For locals, the installation represents a winter attraction that pairs outdoor nature access with a guided wellness ritual, and Fiorst’s stated plans to expand suggest more pop-up sauna opportunities could be coming to the region.
