Nestled in the dunes of Seaton Sluice on the Northumberland coast, a cosy wooden sauna radiates warmth, literally and figuratively. In our very first episode of Coastal Conversations, we sit down with Rosie Edmonds, a yoga teacher and founder of Snug Sauna, to talk about wild saunas, community, and coastal living.

Once reserved for elite athletes and wellness enthusiasts, contrast therapy (moving between intense heat and cold) has entered the cultural mainstream. Its benefits are well documented: improved circulation, reduced inflammation, and mental clarity. But beyond the science, there’s something deeper at play. In the ritual of sweat and plunge, people are finding a way to reset. Contrast therapy feels less like a treatment and more like a quiet rite of passage: a modern day baptism in steam and sea.

“As if I get to do this”

Rosie’s story starts with a return to her roots. After years away, she moved back to the North East and felt an instant pull to the sea. “Every day I still have that pinch me moment,” she says. “As if I get to do this.”

That reconnection to place sparked something deeper: a desire to create a wellness space grounded in nature and community. Inspired by a wild sauna in Norfolk and the unused horsebox sitting on her Grandad’s farm, Rosie envisioned a sauna experience by the sea. And just like that, Snug Sauna was born.

From Horsebox to Haven

The path from idea to reality wasn’t exactly smooth. Rosie spent months collecting materials and storing them in a barn, waiting for the right moment to begin. With encouragement from her partner and hands on support from family, the build finally took shape. “I had no idea what I was doing,” she laughs. “But I had the drive.”

Now Snug Sauna sits quietly in the dunes, welcoming guests year round in rain, shine, or sideways wind.

Creating Connection, One Session at a Time

Despite being new to Seaton Sluice, Rosie was warmly welcomed by the local community. Morning dog walkers became familiar faces, and sauna regulars began forming bonds with one another. “People open up in there,” she shares. “The darkness, the heat, and the side by side benches invite deeper conversations.”

Guests often exchange numbers, return week after week, and leave transformed. It’s all about connecting with others surrounded by the elements.

Food, Movement, and the Sea

For Rosie, wellbeing is more than a session in the sauna. It's a way of life deeply tied to nourishment and slowing down. “When you start connecting to your body through movement or heat, you begin thinking differently about what you put into it too,” she explains.

Local food plays a quiet but important role in that lifestyle, whether it’s a mindful, post-sauna breakfast or simply being more aware of where food comes from. “Living by the sea makes you care more about the environment and your choices.”

For the Curious First-Timer

If you’ve never stepped into a wild sauna before, Rosie has one message: It’s okay to go at your own pace. There's no timer. No pressure. The sea dip is optional. And she’ll be there to guide you. “It’s about listening to your body, feeling safe, and doing what feels right for you.”

What does connecting to the coast mean?

For Rosie, it’s everything:

“It makes me feel at ease and free. When I drive here in the morning and see the sea glistening, I’m know I’m home.”
