Self Contained Composting Toilet with Close Quarters Spider Handle Design

I purchased this in 2021 and have traveled ~6 months every year using it daily.We use coco fiber core. It lasts about 2 weeks. What’s amazing is there is no foul odor while changing. Each change we thoroughly wash and disinfect all.Every day we empty the liquid side, shake dish soapy water, and rinse. We use disinfectant wipes around the connection between the toilet and liquid tank.After each use we spray the liquid side of the toilet with a vinegar - water solution to “flush”.The fan is kept running all the time.The installation was extremely easy. I couldn’t recommend this product enough.

I bought this Toilet system for my vintage Airstream that is parked as a farm dwelling in rural Montana. While it does take a few minutes of reading to understand the system, if you use it with care and pay attention to your output, it works very well. I found it easy to install. I was able to adapt a vent opening to connect the vent hose to the existing toilet exhaust in the Airstream. I trimmed the vent hose to fit nicely. I've got mine in a narrow space so it's not mounted to the floor--I have to pull it forward to release the side clips to empty the urine container and to slide off the solid waste collector. I've just placed a sturdy washable outdoor rubber mat under it and it doesn't slide or tip as the space is snug. Emptying the Urine Container is simple but you do have to empty often--every 2-3 days for 1 person using only this toilet. The solid waste is a bit trickier, but if you follow the directions and upend the solid bin collector into a bag as directed, it's straight forward. Although I could wait longer, I dump the bin every 4 weeks. I'm able to manage it with a bit of effort in the small bathroom space. I use coconut fiber as the composting material--I bought enough to fill a large covered bin which I store outside in all weather--just add the block to your fiber storage bin and add water as directed--when moistened break into pieces--it looks like nice clean brown fibrous material--just allow plenty of room for the coco fiber brick to expand. You can then scoop the coconut fiber into the toilet solid waste receptacle to the right level. When you're ready to empty the solid waste, do stretch the opening of a 13 gallon kitchen bag over the opening of the base tightly over the rim so that you can invert the base and empty the contents into the bag--I use a 13 gallon composting bag. Don't count on the waste to be fully composted when it comes out of the bin although it isn't smelly if you use the toilet as directed. You'll want to dispose of the waste in a responsible manner--further composting or approved disposal method. I dump mine into a fully contained disposal compost system used only for this waste--it will take a long time to fill my system since it contains only the solids from one toilet/one person. I intend to compost it for 2 full years before using it--and then around trees we've planted. So far, I've used the toilet for Fall and Winter use in a mostly heated space but I'll update the review after a full year. I've tried multiple systems for toilet waste--and am very happy with the comfort of the toilet, functionality, cleanliness and appearance. If the costs were less, I'd buy several for our farm--as it is, they're a bit of an investment although I'm very happy to have mine.Edit update. As of May 2022 I’m still completely happy with the toilet and it is still functioning as intended.

I have been using the Nature's Head toilet for about three months on a 34 foot sailboat. Has to be one of the best upgrades any boat owner could ever consider. There is absolutely no problem with odor and the installation was a snap. By far, the most difficult part was removing the old head and all of the associated gear that went with it. The old hoses were nearly choked off from calcium crystals and were only two years old. Removal of the hoses and holding tank provided a huge increase in storage space and it is sure nice to not be sleeping over "you know what" sloshing around in your holding tank. Servicing the liquid tank is a easy, just remove, screw on the cap and dump out when ashore. Make sure you don't lose the cap like I was stupid enough to do. I can't speak yet about emptying the solids container, as it is not close to being ready. I have to say though, there is no way emptying it can be as bad as all the head maintenance required throughout the year. Oh yeah, no winterization work either, big, big plus here in Maine. I did face a few challenges, mostly related to my boat configuration. The NH sits fairly tall just on its on and is a bit larger than most marine heads. That means shorter crew members on the boat are at a bit of a comfort disadvantage. I added a 3 inch raised foot platform, but really needed more like six (in my boat). Side to side access is fine, but check all the measurements carefully before placing in a small space. Same for front to back and make sure you allow for space to tilt the upper assembly when it comes time for solids removal. I have had no issues with small gnats, but based on other user comments I added a small filter screen on the end of the vent hose. We are currently using coco noir for the solids tank. The material is easy to store in compressed form, but does comes with a bit of learning curve when it ones to expanding for use and getting just the right amount of moisture. It can be a messy and frustrating process. Might give peat moss a try on the next refill. Build quality is excellent and overall the design is well thought out. I do think the overall product is a bit overpriced ( six people in my boatyard would buy the head at $500 or less, only two plan to buy at the current price). Even at the current price, I still feel like this was a huge win for cruising comfort.
