The Washroom
The big project is building an outdoor washroom. The current facilities are a pit toilet and lots of trees. The goal is an 8x8 structure containing a shower, sink, and sawdust toilet. Water will be gravity-fed from the water-catchment system on the cabin. Some of the water will go into black hose coiled on the washroom roof, which will be heated by the sun for hot water. Therefore, the location needed to meet various criteria: mostly level, downhill from the cabin, with a southern exposure. We found such a spot, staked out the corners, and trampled down the grass. Now the fun would begin. In researching the type of foundation to build, we learned about the concept of frost heave, where the ground freezes and expands upward - no good for buildings. To avoid having the building move around, footers need to extend below the frost line, which around here is 5 feet. We planned to use a product called a footer tube, which is similar to a 5-foot, rigid, plastic traffic cone. Actually, fou...
