Simple Toilet : dig a hole, poop and wipe
You can use it when your outdoors. Simple!
Every time my friend goes to the bathroom its like a bomb went off. Ths emergency TP may remind him to go a little easier on everyone else in the vicinitity
A toilet and sink combo? The wasteful water for the sink is what fills up the water in the toilet... definitely eco-friendly and a water saver. 2 for the price of 1. Perfect.
