One more composting toilet install/review. Two years off and on usage.

Thought I'd share my composting toilet views/thoughts.

Not sure where all the pictures went. Go here to see them on my site. Firstroamer/Toilet.

Nope, that's not the composting toilet. That is what came in the truck, a slightly lesser version than I had in my sportsmobile. As you can see, there has been a considerable amount of water leaking here for a long time. I was so disgusted with my previous porta potti that I cleaned it up really well and left it in a campground in Idaho for some "lucky" traveler to find. This one, although brand new went right into the dumpster. It was time to give the composting toilet a try.

After much research I ended up with the Natures Head toilet. It was between that and the Airhead. Either one would have worked, but the Natures Head fit the space better. It is built well, but still seems overpriced at more than 900 dollars for some molded plastic and stainless steel. I can't imagine they sell a lot so maybe it's justified. Notice in this picture the toilet overhangs onto the covered shower.

At the back of the toilet the fuel fill lines are keeping it from moving back against the wall. Arrgh, I thought this one was going to be easy.

I had to somehow move these filler lines back or out of the way. Since I only needed a few inches I decided the best course of action would be to cut around the hoses and push them back a bit.

I cut this out of the floor. Nice to see what the camper is made of. Nida-core with an extra aluminum skin for the bottom. It is some seriously tough shtuff.

Had to change the angle on the filler tubes also. Cut here and.....

Spin it around and then re-weld. Yeah right. Did you know they use lead to seal the gas cap part to the rest of the tube. I didn't, I gave this one over to my father who has been welding/brazing for 50 years. It wasn't pretty, but held pressure when tested in the end.

After many hours of fighting I had this. Not much difference, but just enough.

To make these toilets work properly you need a vent. I worked this up with boat parts. A stainless vent going through the roof and a clamshell cover that keeps the rain out and probably even pulls a draft while driving. The vent is powered by a tiny computer fan which runs constantly and uses .2 amps if memory serves.

The vent goes up the square channel in the corner. Other than that the install is very easy. Just screw a couple of "L" brackets to the floor and use the supplied hardware to bolt it down.

This composting toilet is easily one of the best things I've done for my camper. I am completely sold on the idea. The best part for me is not having to do the dump station thing. As most of you know it's a disgusting job. Often times where I travel there weren't stations available and I'd have to go out of my way to find one. The smell from having a black tank is annoying especially when getting full. The composting toilet has no smell, not kidding. Even when the toilet is in use for serious business there is no smell. The little fan pulls the good stuff out the vent.

One of the biggest reasons for getting the composter was the water issue. Flushing a "normal" RV toilet uses a lot of water. The composting toilet uses none. My 50 gallons goes so much farther than it used to.

I've had my toilet installed since May of 2014. I have dumped it exactly twice now. Keep in mind I use other facilities whenever available. Over the last 10 months I've been using the camper exclusively (as in not parked where there is another toilet available) for 4 months. In those 4 months I've had guests off and on. The bottom line is that there can be a long time between dumping of the toilet. Especially with a lifestyle like mine where the composter sits for long intervals. When it got full I dumped it way out in the wilderness into a hole. Once again, no smell, looks like compost from Home Depot.

Here's a look at the bottom part of the toilet. See the pee tank in the front. One bummer about this set up is that you have to expose the number 2 area to remove the pee tank. I was worried it would be a smelly job, but not so.


It can't be all good news and as much as I like to share the virtues there are some negatives. If the pee tank isn't dumped regularly (at least every few days) it will really stink when dumped. No smell inside, only unpleasant to dump. Bugs, yep you heard right. All of a sudden I started seeing these tiny beetles flying around. They had gotten into the compost and were thriving. No big deal, just a little annoying when one runs across the ipad at night and you know exactly where it came from. I just shrugged and said "faster break down of the nasties". ---Update--- this only happened once.


I have no affiliation with Natures head, just think it's a great idea and wish I'd gotten one years ago.


------Update June 2016-----

I have been using the composting toilet now for a couple of years. I give it 5 out of 5 stars. Last week I took the toilet out and did a total clean and inspection. The vent fan was getting clogged with fuzz, but other than that no worries or issues. I cleaned the intake and outlet screens for the fan and all is well.


Two improvements I'd like to see with the toilet. The dumping of the pee tank is a pain. We try to use the outside as much as possible for number 1, but there are always those times we use the inside. Like I said earlier, it can be rather nasty dumping that tank if it sits for long periods. I'm going to rig up some sort of PVC tank with a direct dump onto the ground. The idea is to have a smaller tank for when needed (friends driveway) and a valve for dumping it onto the ground when in the boonies. No more pulling a tank out, just open the valve. We do a lot of travel camping which involves one or two nights in a spot in the boonies. With this new set up we would just leave the valve open and it would be like peeing under the truck for two days. No big deal. The other improvement would be for the 'mixer'. The way is works now, there is a square box and a round mixer. This leaves the corners of the compost unmolested. I've found that you can greatly extend the life of the compost or time between dumpings if you stir that portion into the mix once or twice. Sounds gross, but once again it just isn't bad at all.


One other thing to consider with a composting toilet. You can't cross from Canada to the states with any extra compost. I usually carry a cubic foot or so with me and found out the hard way that they will take it at the border.

Funny you can't take compost across the border! Guess its easy enough to buy some more later pretty easily.

We have had ours 18 months, full time. No issues crossing the border with peat moss or a toilet in use.
Good assessment, we dump every 4-6 weeks.

I'm sure it depends which guy you get. Last time I went through they tore the truck apart and caught me red handed with..... Peat moss. I'm sure you could cross 8 of 10 times without difficulty. They also had no interest in looking at the peat moss in the toilet.

Hahaha. Last time they caught me with 3 peppers (product of USA, bought in Canada) and half a lemon.

Good to hear the toilet works well. We've one to put in our camper, haven't used it yet but most things I'm hearing about it are positive (pee trap I could see improvements being made on).

Natures head is a good choice. It's expensive........ but still one of the least expensive of all the compost toilets out there one can buy.

Urnine diverter is far less smelly and composting seems to work better. To build your own unit with Unrine diverter there is several ways . More info http://www.cruisersforum.com/forums/f115/self-designed-large-capacity-compost-head-104810.html

Inserts one can buy.

Home made

Add a big funnel and hose to seperate container or ground to the inside front of your homemade compost toilet.

Sounds crazy but you can even convert urnine to non potable water. There is a youtube video with the chemical formula's. It was a gardening tip video so search with that in mind.

This post has inspired me to make my own composting toilet. I was considering the natures head but fitting it where I need it to go was not going to be easy or elegant. I can fabricate whatever I need to build one that fits my space perfectly so..... Not sure why I didn't think to build my own from the get go. I would like an external pee reservoir that I can mount under the camper. Then when I am in an appropriate place, I can just remove the reservoir and let it drain to the ground.

Consider using an electronic ball valve to open the pee tank. I did this for my grey tank and it's been one of my favorite modifications. Closed on the highway or city. Open when out in the back country. Controlled from the drivers seat.

I have an easy solution for stoping the urine smell,,pour few drops of javex bleach in the jug,,I did that with my porta potty and it killed everything..

Or you could pour it on the ground. Too simple perhaps.
There are places in USA where you will get fined for that. Besides...... popular spots start getting nasty. Even hikers are incouraged to pack EVERYTHING out when on popular trails etc. for same reason. Example... people been complaining about Rubicon for years cause the yearly collection of piss and crap spread out all over the place by the end of year ..... builds upto some nasties by seasons end. Granted that example is not "land" as much as it is "rock" so it does not soak into mother earth as easy either.

This dropping of waste also encourages the Wacko Environmentalist to start yelling about wanting their Gobbament to block Motorized Expeidtioners access to public lands cause of exploreres who drop un-natural, natural waste out in the wilderness.

Just somethings to consider.

Pouring urine on the ground is not going to get you fined, Don't dump it in a camp site .
The compost is another issue, there are plenty of pit toilets around the world.
