About Thermo Retreats LTD

Sadie Lea Minifee founded Barrel Sauna UK and Fullscope Woodworks with a vision built from the ground up. In the early days, rather than focusing on mass production or maintaining large stock, Sadie focused on the art of the showcase.

By bringing her unique designs to major exhibitions, she allowed the quality of the work to speak for itself.

​

The response was immediate and overwhelming—culminating in being voted the Most

Favored Stand at the Ideal Home Show in London.

​

Today, that same founding spirit drives the brand. Sadie remains deeply committed to a green footprint, intentionally avoiding the path of mass production in favor of intentional, high-quality builds. As the brand continues to grow, our focus remains on sustainable craftsmanship and the personal touch that started it all.
