Maa Sauna

Discover the Maa Sauna — an authentic Finnish experience, just as it was meant to be. We also call it our primal sauna, or earth sauna, as maa is the Finnish word for “earth.”

Half underground...

The Maa Sauna was originally built half underground—hence the name. And that’s exactly what we’ve recreated here at Thermen Soesterberg. The sauna is partially sunken into the ground, giving you a uniquely sheltered feeling. But it offers even more: the earth naturally helps retain the warmth of the wood-fired sauna.

Constructed from Finnish Kelo wood, the Maa Sauna enhances this effect, creating an optimal and delightfully comfortable sauna climate. You’ll feel a dry, soft, and healthy warmth as temperatures rise up to 110 degrees. Experience the healing power of this original sauna and give your health a natural boost!
