Compost toilets can provide a sanitation solution when water or electricity are not available, or when you simply want to make more compost or less environmental pollution.
A hinged compost toilet box will be 18 inches wide and 21 inches long. Get two boards 3/4 inch by 10 inches by 18 inches and two 3/4 inch by 10 inches by 19.5 inches. Get two hinges. Get one piece of plywood 3/4 inch by 18 inch by 18 inch and one 3/4 inch by 3 inch by 18 inch. Hinge the two pieces of plywood together.
Cut a hole in the larger piece of plywood to fit the top of the 5 gallon toilet receptacle. Make sure the hole is only 1.5 inches back from the front edge of the plywood. Always use identical receptacles in a humanure toilet so they will all fit correctly. Buy a standard toilet seat.
Yes, you can instead buy a cheap plastic toilet seat lid that snaps onto a five-gallon bucket, but the resulting toilet is not stable and can tip over when you lean (such as when you wipe your butt)!! You need the box for stablization.
When screwing the legs to the inside of the box, make sure the top edge of the box will sit about 1/2 inch below the top edge of the toilet receptacle (the top of the toilet receptacle rim will protrude through the box by about 1/2 inch).
