All of the angles of the Finncube sauna are assembled using dovetail joints, eliminating the requirement of a fabrication with screws or bolts. In addition, the pieces of wood used for the construction are composed of six technical layers stuck together, this method has been proven to reduce cracking in the wood.
Foundations are not needed for installing a Finncube sauna. It can be installed on a concrete slab or even on outdoor tiles. Its structure resembles a Lego structure: if you move houses, the sauna can be easily dismantled and reinstalled in your new garden.
