When we started thinking about life on the bus being a long term endeavor, it changed the way we thought about toilets, black water tanks (the place where all the poo and pee are stored), and water consumption. We anticipate that the majority of our time will be spent parked on our friends (who also bought a bus for conversion) property. When parked there we will not have easy access to dump the black tank and that means we would have to drive to a gas station to empty the tank. We didn't want to have to drive the bus to the gas station every week to dump the tank. Imagine the 9pm emergency trip to the gas station to dump the tanks because we forgot to check how full it was and its about to overflow into the bus. We wanted to avoid this and we also wanted to avoid Denver looking like cousin Eddie from Christmas Vacation.
So we decided to use a composting toilet for our bus. Which to some may sound worse than than dumping a black water tank, but to us it just makes sense. By using a composting toilet we avoided having to add more plumbing and we are saving our water supply which will be limited in the winter months. We have also increased our ability to be off-grid for longer periods of time.
The toilet is made by a company called Natures Head and it can be purchased on Amazon with prime shipping (link below). We read a lot of reviews and watched several videos on how the toilet works in the real world. Everyone does it a little different but the main concept of use and products for the toilet are similar, It honestly seems pretty easy to use and maintain. The pee and poo go in to separate compartments. Poo gets mixed with peat moss and pee gets held in an easy to handle container this prevents the smell of sewage. After 80 uses the poo container can emptied and its contents used as potting soil for non edible plants. It can also be placed in a bag and thrown away.
This is definitely the most expensive toilet we will ever buy, but after doing some rough calculations on the cost to purchase and plumb an RV toilet it would be about the same as the cost of this toilet.
This is our first experience with a composting toilet so we are going to be learning as we go, but we are excited to try it. We aren't sure how it's going to work out, but are ready for the challenges that lie ahead. We will be sure to post an update about our experiences with the composting toilet.
