Erm…How about a bathroom?
As far as peeing is concerned we just did it away from the yurt. Pooping is a little more complicated but not a big headache. We had a 5 gallon bucket with a toilet seat on it. Every time we used it we’d put leaves/dirt on top which kept it from smelling. When full we’d empty it a ways away from the yurt where we composted it – it composts quite nicely and has no smell at all.
