In this tutorial, we learn how to make a compost toilet. First, you will need a 5 gallon bucket. Then, you will need to put a toilet seat on top of it so it's comfortable. After this, build a cabinet around it to make it look nice. After this, you will need to put something inside it, like sawdust, which will absorb the liquid inside. Now, you can feel free to use this for a bathroom! For ventilation, you can use a hair dryer from your local thrift store which will connect to the back wall and vent smells out. This works great and saves you money.
