Cladding with ventilation and furniture frames
At the top is a part of the sloping ceiling. On the left is a wall covered in vertical wooden cladding with a 20 centimeter broad horizontal plank at the top of it. Attached to the wall are two rectangular wooden frames reaching out of the picture to the right. One is broader and higher at the back of tha sauna, the other is lower and narrower, with its back edge below the front edge of the broader one. To the right is the back wall, also covered in vertical wooden cladding. Just below the back wooden frame there is a long narrow horizontal slit in the back wall cladding, through which the blue vapour retarder is visible, reaching from the left wall at least nine cladding-board widths over to the right edge of the picture.
