Hi, I’m Katie, founder of Stone & Steam Wild Spa. My journey into sauna culture began with a deep commitment to mental health and community well-being. After more than a decade working in mental health services and running urban community gardens, I saw first-hand how isolation, stress, and disconnection from nature were impacting people’s lives. Saunas, I realised, could offer a powerful alternative — a space of prevention, healing, and togetherness.

Travel then deepened this path. From the Temazcales of Central America to Morocco’s Hamams and Lithuania’s Pirtis, I learned how different cultures use heat for ritual, therapy, and connection. Inspired, I built my first wood-fired sauna in 2020.

To bring this vision to the UK, I trained as a sauna host in 2021, studying the science of hot and cold exposure, therapeutic practices and sauna rituals. Following this I was supported and funded by the King’s Trust ‘young enterprise scheme’ which allowed me to complete this sauna build.

At the heart of Stone & Steam is my belief that saunas are more than wellness — they are modern sanctuaries, a welcoming alternative to the pub, and a place where stories, rituals, and community thrive. As your sauna host, I tend the fire, guide the rituals, and hold space so every guest feels safe, included, and cared for.
