P3s or Thunderboxes or Treasure Trunks, are small open to air boxes you sit on that are built over a dirt hole that is filled in when full, they then replace the shitter by digging a new hole and putting the seat overtop of it, these are typically used in the backcountry.
Privatories or Privis or Outhouses are full buildings constructed over a concrete box which you shit into, that box is emptied once or twice a season, these are typically used in actual campgrounds.
Clivises or Composting Toilets are Swedish made composting toilets that use a tank that churns the shit and everything mixed with sawdust and wood waste to produce usable fertilizer which then gets used to fertilize crops, the most disgusting part of this is that some units need to be manually raked by a poor sap who drew the short straw, you literally open a hatch in the tank and rake it to remove any blockages or clumps. These are usually used as single units at popular day use areas.
Additionally there's comfort stations but those are just regular bathrooms with electricity and shit so theyre not that interesting.
There's also a literal book on how to build P3s and Privis, it details everything from the width of the door, to the shade of paint to the fucking color of the toilet seat. It also literally lists the height of the roof down to the millimeter.
