Re: Air Head Composting Toilet or Similar Mfg.
We found the Natures Head to not separate at the urine diverter very well (allowing a lot of pee into the poop part). We found the whole experience of using the Natures Head (or any composting head) to be fairly gross. We are in the minority on this, but it's how we felt about it. We really wanted to like it, but just couldn't.
If I had it to do over again and had the same parameters (no through hulls), I'd go cedar bucket or plastic bucket with a seat. Buck it and chuck it, and save the $800.
I never liked the trap door over the big hole ( Conservative birth canal). So I just raised the lip around it, and went for a lift out stainless lid from the thrift store. No liquids getting into the compost, and a far simpler solution. I just remove it when taking a dump. The rest of the time it keeps the compost drier.
No complaints with mine. Cost me under $25 to build. I'd never go back to a traditional head.
