Tiny House Composting Toilet Blues

composting toilet

I’ve been living in my tiny house now for a good while and the big challenge of composting toilet has been going well.  Initially I had wanted to have a flush toilet and my house is setup so I could drop a toilet let in quickly, but the quotes for a sewer line alone started at $50,000 so I begrudgingly went with the composting toilet.

I haven’t really read too much online about people’s experiences with composting toilets, the few I’ve read were just over the moon, glowing reviews.  So I thought I’d share my experience so far.  It has mostly been positive and easier than I thought, but with this recent incident it goes to show it isn’t all great.

It's more than a dietThe other thing I don’t think people talk about in their composting toilet posts is diet.  I have learned that a good diet beyond good health, impacts how easy it is to use a composting toilet.  Good healthy foods, meals with salads, and less processed foods makes composting toilets easier to manage.

With a good diet your body functions better, it can extract more moisture and nutrients out of the what you eat and keeps things with composting toilets easier.  I also know the better one eats, the more regular one is; for my body, I usually need to visit the restroom at 10:30 am almost without fail, which 9 times out of 10 means I’m out and about, where there are toilets for me to use.  So diet is worth noting and was something I felt was missing from the discussion.

Currently it is illegal in my city have a composting toilet, as it is in most municipalities; plus I’m renting my land, so I wouldn’t want to be composting on land I don’t own.  What seems like the happy medium and it is what I do, is bagging the waste every week into a biodegradable “plastic” bag and then sending it along with the city trash; at that point its essentially like a diaper, but the plastic will breakdown in a landfill quickly.  There are other options out there for this too and I considered them, but for me this works.

I am currently using pine bedding (from the pets section) which has a nice scent, but I don’t think it absorbs as well as other options.  I’m thinking I’m going to switch to a mix of half pine bedding and half mix of peat moss which is very absorbent.  Peat moss is a pretty good option, but it isn’t a sustainable material, it’s harvesting is actually quite destructive to wet lands.  I know for gardening that coconut coir (husks) is the sustainable version of peat, but I don’t know how it performs in composting toilets.  I’ve ordered an 11 lb block of coconut coir for $16 to try out, which I’ll report back on later.

It has been pretty straight forward, but I still opt to keep my bucket setup outdoors.  I do keep my liquids and solids separate, which at this point means I go peep in the woods and then use the bucket.  Later on I hope add a urine diverter later on, but it isn’t a must at this time.  I have a mini deck space that I keep it on.  The smell isn’t anything to be concerned over, but I’m not sure having it inside with no moving air would be a good idea at this point.

luggable looMy bucket has a pretty tight seal on the lid, so it is pretty hard for things to crawl in, but it is possible.  The other day I went to use my setup and when I opened the lid, I was greeted by a swarm of fly larva.  A hundred wriggling maggots.  It was gross!    What was interesting was they were on the seat between the seat and the lid.  What I don’t know is if that was because the flies couldn’t get into the toilet or if they just preferred that narrow space.

Luckily it was very simple to take care of.  I easily popped off the lid, then hosed it off in a very sunny spot.  I figured the intense sun would kill the larvae so I didn’t have a ton of flies.  I double bag the bucket so I closed the first bag, then tied up the second bag that was still clean.  Job done, took all of two minutes, but I realized something is flawed in my system.

I did some googling to discover that this is a semi-common issue when the heat of summer comes on.  You’ll be going along in the winter, it gets warmer and then all a sudden the flies come out.  I learned about a product called Mosquito Dunk, which you crumble into a spray bottle, mix up with water and then when you use the toilet, you give it a few mists on the surface.

mosquito dunkMosquito Dunk as described by the maker  is a “larvaecide that kills mosquito larvae only. It is deemed organic by the USEPA.  Dunks are harmless to beneficial insects, pets, birds, fish or wildlife.  Kills within hours and lasts for up to 30 days.”

So I’m going to give this option a try and see how things pan out.  I will report back in a few months as I learn more,
