How do you build the full wooden back of the self-build sauna?

1. Rear wall installation:
   • Place the middle part of the back wall in the groove. Make sure it lies deep in the groove.
   • Screw the wall from the bottom center of the groove with a 4.5x60 screw.
2. Back Wall Sides:
   • Place the two sides of the back wall. Make sure they fall properly into the groove and that the numbers match.
   • Attach the side panels to the center panel with two 4.5x60 screws for the bottom and two 5x100 screws for the top.

General Steps After Installing Back Wall

1. Installing Half Moon Profiles:
   • Place a crescent profile on the two walls. Make sure that the walls fall into the groove of the crescent profile.
   • All of them place the left crescent profiles on the left side and screw them in with two 4.5x60 screws per half moon profile. Use a rubber hammer for a good connection.
   • Repeat this process for the right crescent profiles on the right.
2. Install Top Profiles:
   • Place the remaining left and right crescent profiles without screws. Leave enough space on top so that one more profile can be inserted.
   • Delete the top middle crescent profile.
   • Place the last double crescent profile, possibly use a rubber hammer to position it.
3. Attach straps:
   • Place the straps and tighten them manually. Remove the screws in the formwork up to the slipper.
   • Tighten the tires and, while tensioning, beat the formwork into the correct shape with a rubber hammer. Tighten the tires with an impact driver and a wrench.
4. Confirm Rain Gutters:
   • Attach the rain guides to the formwork with 4.5x60 screws on both sides, one screw approximately every meter.
