Meet the new Nukk Sisu Sauna.
This build introduces our raw Finnish-inspired board and batten exterior — a simple, durable cladding style chosen for the same reason we build every Sisu Sauna the way we do: longevity.
The exterior is designed to be practical, honest, and easy to live with. No complicated finishes. No fragile surfaces. Just a strong timber shell that can weather naturally, be maintained easily, and repaired simply if it ever needs it.
At Sisu Sauna, we don’t build saunas to look good for one season.
We build them to settle into your home, your garden, your routine — and to keep giving back for years to come.
Raw. Minimal. Built to last.
Sisu Sauna — made with longevity in mind.
