Sauna Companies Hate Me For Building This

What happens here

After the base frame is established, plywood sheathing is cut and attached to the top of the frame to create a solid subfloor for the sauna. The builder is shown using a cordless drill/driver to secure the plywood. Following this, pre-framed wall sections, typically constructed off-site for efficiency, are lifted into place on the subfloor. These wall frames are then securely fastened to the subfloor and to each other to form the main structure of the sauna.

Goal: Build the floor and primary vertical structure of the sauna
