Nature's Head Self Contained Composting Toilet with Close Quarters Spider Handle Design

I can't fully express how well this toilet works. I was a little aprehensive about living full time with a composting toilet. I had done a fair bit of research on the topic in preparation for living in a tiny house and this one seemed to be the clear leader.I had so many concerns: would it have an unpleasant odor? Would it be difficult to use? Would it require constant cleaning? What about installation? Most importantly, HOW WILL I LEARN TO AIM??Well I am pleased to report after two weeks of full time use that all my concerns are calmed.Firstly, it has no discernable odor, even when the lid is lifted or the upper portion is lifted partially when removing the liquids bottle to empty it every other day or so. Even when in use it us less odiferous than a standard flush toilet because the little onboard fan is constantly whisking any odors right out the vent hose.It is not difficult to use, just sit and go. Open the trap door before a solids deposit of course, but otherwise just do what you do naturally.Installation was easy, this 50 ish woman with slightly above average handy person skills did it in 15 minutes.Cleaning is simple if you spray down the inside of the bowl with a water and white vinegar mix after EVERY use and perform a minor wipe up with a paper towel (which you then just drop into the trap door) if you have a particularly egregious contact mark. Which leads me to AIMING, which is not even a thing, just sit down comfortably. This thing is so well designed that unless you have some wildly divergent anatomy that I can't even imagine, it is a non issue. That trap door is right where it needs to be. Just remember to open it first. And if you are a dude, just sit already, it's ok, nobody is judging you.As for emptying things, the liquids bottle is easy to remove, cap, carry and dump. I have't got to the point of emptying the solids chamber yet ( I used coir fiber available here on amazon as the composting medium) so I will update if it is anything other than as straightforward and simple as all the other aspects of this product. If you want lots of details on that there are several good youtube videos on the topic.The brilliant design, heavu duty construction, super simple installation and stellar online support makes this worth every single penny.

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.
