Q&A – Composting Toilet for an RV

Q&A – Composting Toilet for an RV

This week we continue our Q&A series with a question fielded from our YouTube subscribers. During our 11 months on the road, many people have wanted to know the scoop on one of our favorite RV modifications.

A composting toilet?! How does it work, and do you like it?


Installation

We installed a Nature’s Head composting toilet in our RV during the final stages of renovation. Torn between having to empty a black water tank or empty a compost “bucket”, our research led us to the latter.

Needing only two L-Brackets to hold it in place, the Nature’s Head toilet is an easy install. It does require 12 volt power and a ventilation hole. We easily wired it into existing wires in the area. The company offers a 110 converter if you’d rather plug it in to an outlet. We routed the ventilation hose into the floor – in an existing hole from our old toilet.

Overall, the installation took about two hours. Most of that time was consumed by figuring out exactly where to place it.

Starting the Compost

To begin the compost, we recommend using Peat Moss or Coco COIR (we buy it on Amazon). The Coco COIR we use comes packaged very dry & tight. You’ll have to chip off the dry material and rehydrate it in a bin or bucket.

We learned how to do this from Gone With the Wynn’s. Here’s their tips:

1. Take off the top, aka the seat and set it out of the way.
2. Break off enough coconut coir or sphagnum peat moss (about a 1 gallon buckets worth) and place it in your bucket.
3. Hydrate the coco coir or sphagnum peat moss (typically comes dehydrated in a solid mass) with water until no dry clumps are visible and it has the look and feel of fresh garden soil (damp and crumbly, not wet). I use approx 1.5 – 2 liters of water.
4. Pour the hydrated coco or moss until it levels out just under or at the agitator.
5. Put the toilet back together and its ready for use.

Using the Toilet

It seems pretty intimidating to use the bathroom on a new device, but before no time it will feel like home!

Toward the front of the toilet are two holes; these holes drain into a urine compartment. The urine tank holds about two gallons of liquid.

In the center of the toilet is the solid waste hole equipped with a lid. A lever on the side of the toilet easily opens and closes the lid. When you have to go, open the lid – and when you’re done, simply close it.

You may put toilet paper in the compost, but it will slow the composting process down and lead to emptying more often.

Cleaning & Emptying

The most annoying aspect of this toilet is how quickly the urine tank becomes full. We empty the urine at least twice a week.

The urine tank is easy to remove and there are a few methods of emptying. When boondocking with no vault toilet, we empty the tank in the woods (and never in the same place twice). When boondocking with vault toilets, we empty the urine in a vault toilet. If we have access to flush toilets, we’ll empty the urine down one of those.

Any method works fine,  just practice common courtesy when handling large amounts of urine in a public area!

The composting tank is fairly easy to clean. We unhook to toilet from the floor, place a large trash bag around the lid, and flip it upside down. Because the substance is considered compost, you can throw it away like everyday trash.

Why We Chose a Composting Toilet?

We wanted a composting toilet for two reasons. First and foremost, our blackwater tank was tiny (7 gallons) and we didn’t want to empty it so often. And secondly, we liked the organic aspect of the Nature’s Head toilet. Dumping strong chemicals into a blackwater tank and filling our camper with that chemical smell is a sure-fire way to harsh our vibe!

Overall, we’ve been really happy with the function of our composition toilet.

Have you found there's any stink smell from the toilet? And does your vent go through the existing blackwater tank hole?

Installation took about two hours to find out where to place composing toilet, I think it's long time. Unitl now, are there any better method to reduce this effort?

If your composting toilet is due to be dumped, Can you dump it if you just went # 2 that morning, Or, is it a good idea to wait a couple of hours later in the late afternoon or night ? Another words, How long do you have to wait after fresh bowel movement ?

No toilet paper in the toilet, where does it go, does it smell. How often does the bowl need to be cleaned to look clean and free of residue? Your post has me considering the purchase. Thank you!
