Our floors are made from a 14 oz light brown heavy vinyl. We prefer this material for its toughness, ease of cleaning, and its 100% water proof.  It's heavy and flexible enough to walked on without wrinkling the fabric. We heat weld the fabric to not leave any needle work when joining the panels together to give it stronger seal. Our floors can be custom made with a 2" inch Velcro cut-out for the wood stove for an additional price. The floor attaches to the sod cloth by velcro. Another option would be to sewing it to the tent if prefer.
