Authentic Finnish wood-fired sauna experience in Thames, Oxfordshire
Fire + Pine Tar = Ultimate exterior protection.
Here is how we treat our exterior sauna cladding:
Base: Thermo-modified softwood for built-in stability
Step 1: In-house fire treatment and removal of excess burned wood for a beautiful grain to show up and exceptional protection used for thousands of years
Step 2: Svartjära (Black Pine Tar) + raw linseed oil deep condition
The result is a striking black finish that naturally resists moisture, rot, and UV damage. Built to handle the worst weather while looking incredible.

The philosophy of art isn’t just about the finished masterpiece; it’s about the willingness to get your hands dirty in the process.
Shou Sugi Ban (charring wood cladding) is a brutal, messy, and exhausting process. You’re covered in soot, fighting the heat, and chasing perfection with a torch. It is hard work, plain and simple.
But there is a profound beauty in using destruction to create resilience. By charring the surface, we aren’t just changing the color—we are protecting the wood, highlighting its raw texture, and creating an exterior that will stand the test of time. True art demands something from you. And the reward? Absolutely breathtaking.

The Sauna Series: Part 1.
Building our new showroom sauna model from the ground up.
First one is Fire.
Charring Scandinavian thermo-softwood (often called Yakisugi or Shou Sugi Ban) is a brilliant choice. Because the wood is already “thermally modified,” it has very little moisture and high stability, making it react beautifully to heat.
The process creates a carbonized layer that acts as a natural shield against UV rays, insects, and rot.

Our part on the project is done. Waiting to see the results of finished windows and other little bits and pieces as work on the boat is still in progress. Can’t wait to see it finished and running. Thermo aspen cladding looms great even before oil application ❤️

For our last project, sauna on a narrow boat in London for , alongside we have decided to use THERMO ALDER for few reasons:
The Material: Premium Thermo Alder. Heat-treated for enhanced durability and a rich chocolate hue.
The Benefit: Low thermal conductivity. These benches stay comfortable, never “too hot,” even at peak temps.
The Finish: Naturally rot-resistant and chemical-free. A sustainable choice for a floating sanctuary.
