SISU Sauna And Cold Plunge

Overview

SISU Sauna and Cold Plunge is the Treasure Valley’s first exclusive sauna and cold plunge wellness center, located in Meridian, Idaho. This family-owned business, operated by Spencer and Jan Crosland, specializes in traditional Nordic-style contrast therapy, alternating between hot saunas and cold plunges to promote healing, recovery, and well-being. The 1,800-square-foot facility features two private session rooms, creating a serene, welcoming atmosphere inspired by Finnish “Sisu”—a concept embodying stoic determination, grit, and resilience. Patrons enjoy a rejuvenating experience in a clean, modern space emphasizing privacy, hydration, and social interaction, with up to 6 people per session (or more for groups). The overall vibe is relaxing yet invigorating, fostering physical detoxification, mental clarity, and community in a low-impact wellness setting.
