We Make ALL Our Saunas in Thailand

Every Sisu sauna is designed and handcrafted in Thailand — not shipped in a box from China. Our Finnish-trained team of Thai carpenters builds each one with premium hand-picked timber, properly insulated walls, and 12mm tempered glass as standard. The quality speaks for itself, and so does the longevity.

What makes Sisu different?

Unlike most sauna companies, we build ours right here in Thailand with our talented team of Thai carpenters, overseen by our Finnish sauna guru.

Most saunas on the market are imported from China. Ours aren’t, and the difference is obvious.

Better construction. Hand-picked premium timber. Thicker, properly insulated walls that hold temperature instead of leaking heat. 12mm tempered glass, not flimsy 8mm. Quicker build and delivery times. We could go on.

We’re proud to support Thai craftsmanship, and prouder still of what we design and build.

With Sisu, you’re getting the finest quality sauna money can buy, built to last.
