I almost forgot, dealing with human waste is a big issue.

For very short-term, a new 5-gallon plastic bucket and a clip-on toilet seat/lid and some sawdust/leaves/stove pellets/organic pet litter/compost, etc. Don't be tempted to use clay cat litter, trust me.

For the longer term, there is a really good book called The Humanure Handbook by Joseph Jenkins. It comes in paper and free online (includes drawings and photos). He answers all your questions, plus some you never thought to ask.

Just digging a hole in the ground and letting the waste get into the groundwater is not cool.
