Composting Toilet

A composting toilet has been one of the best off the grid mods we've made. A composting toilet doesn’t use any water, its environmentally friendly and we don’t have to worry about a stinkin’ black tank! Sound too good to be true? Click on any of the posts below for more information.

    Is there a certain length of time you must wait between your last 'go' and when you can dump the compost bin?

      Natures Head suggests waiting 6-8 hours...for us we wait overnight and take care of dumping and refreshing it first thing in the morning.

    hi there - we are going to use a Seperett composter that separates urine and feces. The holding tank for the urine will go under our Sprinter; from what I'm reading, once diluted the urine is good for plants and shrubs and trees. My question - do you know whether the kitchen sink grey water can go into that same urine holding tank to serve as a dilutent, or would it cause other problems (food particles, bacteria, etc)? If you know or have suggestions where I can go, thanks!

    A quick question - do you deposit toilet paper in the Composting toilet? It doesn't break down without liquids.

    I am planning on buying a new fifth wheel trailer to live in soon. Would it be a good idea to have the RV dealer install the Natures Head or would you do it yourself. I know you did a video on this but the fifth wheel has a lot more room and access. Thanks

      If you're handy I would suggest installing yourself, otherwise you'll be paying the dealership $100/hr to 'figure it out'

    My wife and I have just recently built our own motorhome from a Ford Tranist (UK name) van. The most novel feature was the installation of a Natures Head Composting Toilet, which we decided to purchase based on your videos. I have to say how much my wife and I are impressed with the solution, and as you have said repeatedly there is no smell.

    The Composting toilet is a very simple and practical alternative for installation in a motorhome or RV. The design is simple and elegant ensuring that it is easy to maintain and use. The fact that it comes apart into three sections and only uses two nuts to secure it means that it is simple to install and easy to remove if you need to clean it.

    There has been a lot of discussion about smell, which was something we were concerned about. As has been stated by both Jason and Nikki, the toilet is completely odorless!

    As an aside the first time my wife used it, she suddenly screamed that the toilet was leaking, after jumping into the motorhome shouting I'll get some paper, don't panic, only to be greeted by my wife laughing at me .... All was fine.

    The one thing that surprised us the noise wee makes when going into the collecting vessel, which is something we had not thought of, only a minor observation.

    Since installing it two of my friends who are both motohomers are considering installing this toilet as they are both amazed at the practicality of it.

    Also people are quite taken aback when you say you have a composting toilet in your motorhome. However everyone we have shown it to are very impressed with what it is and how it works.

    Thanks so much
    Chris & Teresa

      Thanks for the kind words and we're so happy you took the "plunge" and decided to go composting in your custom rig. Have fun out there!

    What if you connected the liquid tank to the black tank so you didn't have to empty it so often? Is that something you guys have considered, or is there a reason that wouldn't work?

      Did you ever get an answer? I have been wondering the same thing. It would certainly solve the problem of dumping the liquid bottle every other day.

          Sorry about that. We have not found a solid solution for that yet but it most certainly could be done! When we transition onto a sailboat we hope to have a solution by then.

    For those people who desire to compost at home yet are concerned to maintain their water closets, I suggest changing out the closet to a low flow, say 1.6 gal. and plumb the black water to an Aquatron model 4x100 or greater. This can be in a basement or crawl space below the floor where the closet is located or following a 6 degree minimum continuous down-grade drop to a separate enclosure or "house" with the Aquatron system ( I as an architect, I've found the Swedish Aquatron system to be an amazing composting alternative that utilizes only worms. The entire process from waste to soil will naturally take place by the time you are ready to cycle back to the 1st bin. I recommend running the grey water into a sand filter pond with water hyacinths, then once the water has sifted through the sand bed, plumb this water to your garden.
    Additionally, in consideration of the environment I promote rainwater harvesting in a 10,000 gal. tank rain barn, if your state permits. This will provide all the water a family of 3-4 will need in most areas of the country for daily showers, drinking, cooking, and a weekly car wash. In dryer areas where you receive the bulk of yearly water over a 2 or 3 month period, I suggest doubling the catchment tanks to 2 x 10,000 gal. in a rain barn. With grey water management to fill toilets, you have eliminated one of the major utilities in living. Add to this solar, or if you have some grade and a year round creek, hydro power (vastly more efficient). I've designed several luxury homes successfully utility-free in Arizona, Hawaii, Germany, and Austria. Just wanted to plant the idea.

      I love everything you said. Sadly it's been 2 years, so I'm not sure you'll see this. I'm curious where you went about purchasing your setup? I onoy came across your comment here because I'm already trying to track down an aquatron stateside and it seems very difficult. Any info on you tron and UDFT would be helpful. Thanks!

    Hi guys thanks for the great video on the natureshead my question is how do you clean the potty? Are pinworms or other human parasites an issue, in the event someone may unknowingly be infected? Thanks for your answer.

    I have seen that a single bale of peat moss would last about a year for two people. Do you have any idea how much coir brick would be required to last a year?
