These delightful sauna photos are courtesy of Jim and Karen Martzahl from Wisconsin.  Although this sauna is at their camp in Daggett Michigan. They used dried white cedar that had been dried for seven years.  The roof is 1-inch thick poplar with 1/2 inch styrofoam foil backed. Then 3/4 inch treated plywood then steel roofing.

Beautiful building at sunrise and sunset.

The framework is square, level and plumb. 

Beautiful pieces of Northern White Cedar and a happy cordwood builder!

Teamwork makes the walls rise faster.

Half way up! 

Note the “loaves” of mortar on the scaffolding. 

First sauna for the grandson.  How delightful!   Thank you Jim & Karen for sharing your beautiful cordwood project.
