No offence meant
…but yes you can install a Composting toilet in your rig. As long as you know what you’re doing (Toilet Use) and install the vent pipe system and such correctly they don’t smell at all.
Actually Composting Toilets if used correctly have no nasty smells…where an RV toilet & Black Water tank system stinks under some conditions (Bad Venting, rotten toilet seals etc.)
As far as capacity goes….Good composting Toilets like Sunmars Excel-NE (non-electric) has more than enough capacity for daily residential or RV use for 2-adults.
Millie & I lived with a composting toilet setup for quite a few years on a farm in Oregon and never had any problems with it…I bought a Sumar Composting Toilet to install along with a regular RV toilet for our Bus….
Here’s a pic of it inside our Bus

Because of size constraints (measly 27 feet interior ) we sold the composter.I only got rid of it because I felt it took up necessary room for other stuff I needed to install …not for any other reason.
Here’s a page of ours that shows the toilet in more detail
If I get to build our Trailer , I’m installing a Composting Chamber in the ‘Basement’ and we’ll use a Low-water Sealand RV/Boat toilet inside.
Right below the toilet will be a ‘Y” that has valves on each side that will allow us to either use the Composting Chamber or just Dump it into a Black Water tank (during cold winter months).
Here’s a link to what a Composting Chamber type of setup looks like
I do have to say, I don’t suggest anyone should install a Composting Toilet in their Rigs…unless they first understand the principles of composting human waste products.
This isn’t ‘Rocket Science’ , but it does take some care & diligence in making sure you follow some simple steps.
1-NEVER put anything in the toilet that shouldn’t go there …IE. Old paint, Perfumes, Bleach, Women’s sanitary products, etc.
The only thing that goes into the Composting toilet is the ‘You Know What’, unscented (perfumed) toilet paper and compost starters & helpers (peat moss, sawdust etc.)
2- Try to keep the Composting Toilet and the area that it’s store in at 55-60 Fahrenheit.
Anything below 55 degrees slows down the Action…
It still works, but it takes longer to finish.
But when it gets to the freezing point …composting stops and goes dormant. This doesn’t hurt the Composting Toilet/Chamber , it just stops working until you bring it back up to above 55 degrees.
Here’s a link to Sunmar’s site where they show how a composting toilet works…and what you need to do to keep them working.

Sunmars just one of many Composting Toilets available…I like them because they have a Long and very good record…plus they also make smaller models designed for RV’s and boats…which is nice for folks with small moveable homes.
But there’s other ways to go about this….
Here’s a link to a simple Low-Cost solution called a sawdust toilet …..basically it’s just a 5-gallon bucket w/toilet seat . You ‘use it” and cover stuff up with a bit of sawdust .
When the bucket is somewhat full , you dump it into an composting chamber or pile somewhere outside.
There’s No reason you couldn’t add a vent to the back of this type of system to use in a rig.
This is Very Cool …The Folks who put out probably the Best book ever written on this subject ‘The Humanure Handbook ‘ have set up a website with lots of info from the book …
Here’s the link
Composting Toilets aren’t for everybody …I’m not advocating their use or anything here.
I just really like them because they allow you to stay in one spot for quite a long time…without worrying where you going to dump your Black Tanks contents.
For me that means if I’m parked somewhere out in the Boonies… that’s just one less thing I need to think about.
