Here is an idea to put in the back of your head in case you ever need it. When we first considered being curators for the Maryland State Park system and restoring this house, one problem was that the house only had one bathroom and there are eight people in our family! I looked on the internet about composting toilets and they run $2,000+, are ugly, and take up a significant amount of space. In addition, I did not like the idea of composting that stuff inside my house. Then I came across the sawdust toilet concept. It is cheap, odor free, and the composting is done outside. We have used it for the past six years and are pleased with it.
We use it similar to the old fashioned chamber pot concept and just use it for #1. The difference is that the carbon in the sawdust keeps down the odor. After each use, or in the morning, we add a fresh layer of sawdust to cover everything up. If there is some smell, we just add more sawdust. We have a sawdust toilet for the boys, one for the girls, and one in the master bedroom. When the buckets are full, we dump them on a compost pile.
Can you find the “bathroom”?
Here it is! I built a box to hide the buckets and toilet seat.
