SAWNA BOCS CEFFYL began with a simple idea — to take something old and full of character, and give it a completely new purpose. The vision was to transform a horse-box into a wood-fired coastal sawna: a space for warmth, recovery and stillness beside the sea.

From the beginning, SAWNA BOCS CEFFYL was imagined as more than a sauna. The setting mattered just as much as the heat — open water, sea air and the rhythm of the Welsh coastline.
Burry Port Harbour felt like the right place to bring those elements together: a simple space to warm up, slow down and reconnect before stepping back outside to the coast.

“The right horsebox had to carry more than equipment — it needed character. Strong enough to become a sauna, compact enough to remain mobile, and full of the history that would make the finished space feel unique. Finding the right starting point became the first physical step in bringing the idea to life.”

The choices are practical, tactile and deliberate: Harvia for dependable heat, Thermowood for its warmth and resilience, and a wood-fired rhythm that asks people to slow down. Every fitting should feel like it belongs there.

SAWNA BOCS CEFFYL started from a simple belief: that feeling better doesn't always need to be complicated. Sometimes its heat, cold water, fresh air and a little bit of time away from everything else.
The aim is to create a place that is welcoming and unpretentious - somewhere people can step away from the noise, reset and leave feeling a little calmer, warmer and more connected than when they arrived.
