Finlandia Pre-Cut Sauna material packages are made to order. Our precut sauna packages are intended for use in a space that you have framed and insulated. Anyone with general carpentry experience can build a Sauna out of our FPC parts. We supply all the interior room parts and you nail our 1"x 4" tongue and groove boards to your studs; our boards will run horizontally. We cut the material and build parts to fit your room; we don't just supply a pile of lumber and unassembled pieces.
