All Finlandia material packages are made to order. Our precut 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 or staple our 1"x 4" tongue and groove boards to your stud frame; our boards will run horizontally. We cut the material and build parts to fit your room; we don't just supply a pile of uncut lumber and unassembled pieces.
