Best Compost Toilet

OGO Toilet Camper Van Potty

🚽 We’re so excited that we don’t have to take crap anymore! No more searching and paying for dumping our cassette toilette. No more smelly, dirty, messy dumping.

We love this OGO Toilet for our campervan!! We can’t say this enough. It really doesn’t smell like potty, it really is easier and less of a mess to maintain over all. It’s comfortable and I love that we can “go” longer without using a messy dumping station and the cleanup is minimal. We have the OGO™ Origin. This version has a fan and vent. I think it is even less aromatic than any other bathroom, home, public or anywhere because of the exhaust vent system!!

OGO Compost Toilet fits a little taller in our “potty box”.

There’s no comparison in our minds if you can budget a compost toilet! I can tell that the OGO™ Origin in particular is the best option out there from personal experience and from talking crap about pottying with lots of fellow camper van home enthusiasts, both part time travelers and those who are full-time living.

The urine diverter and panels are at a slant to drain forward.

The urine diverter helps the ladies and any worry they had about getting pee in the right hole! The fan and the vent installed through the wall gives one a fragrance-free pooing experience for all! It is comfortable, compact and quiet.

The poo panel opens and is at a slant diverting any liquid drips forward.

This “Toilet is one of the smallest composting toilets on market…Only 16″ side to side, 15″ front to back and 18.375″ tall. [The] unique design allows users to have access to every component from the front or top so it can be slide into cabinets, drawers, and other tight spaces without hindering the use.”

Relatively Easy Install for this Van Builder Guy and his Trusty Helper.

Some folks only use their RV potty for special occasions or emergencies. We usually optimize the use of public restrooms during the day on our outings or traveling on the road, but at night and early in the morning, we like the comforts of home. Our philosophy is that we want our tiny home on wheels to feel like “home” as much as we can. As soon as we start diverting more of our efforts from this philosophy, we know we need a change. This is why we switched from a cassette, portable toilet to a compost potty.

Compost Vs Cassette

Portable Toilet

For the first two years as we traveled long distance while we built out our camper van, we used a cassette style, portable toilet. We continued to use this great option even after we finished our build and went on the road full time. These types have an initial lower cost, so when starting out, it seems like the best option, not knowing personally if a compost toilet is better and worth the money.

Our first cassette portable toilet fits great in our “potty box”.

We had many experiences with trying to find a dump station or appropriate toilet to dump the liquid poo and pee mix that accumulates over about 4 days’ worth. The biggest reason we tried the switch to a compost toilet had mostly to do with the effort needed to be taken to dump it and it Had Not become less stressful for us.

As a reference, we use our camper van potty mostly at nights and through to mornings for pee and/or poo for convenience and comfort. During the day, we usually use public restrooms when we are about our day exploring when available or when we’re on the road, heading to our next destination, as long as those public bathrooms are not gross. Check out my TikTok on Goodnight Trail for the series on using public restrooms and some helps for these experiences.

I spray both sections with Lysol

I put that paper in the trash can

May need to wipe bowl clean

I find that liquid (pee or water)

in the toilet bowl first,
lined with a couple squares
of toilet paper for poo
to land on, helps move it
cleanly into black tank.
Note, fresh water rinse can
go up under the seat
if pressed too vigorously.
No wet tush for next time. Gross.

Can have a mulch or

If you have the compost

out the van wall,
virtually no aroma exists,
even when actively pooing.
Can have chemical
porta potty aroma
when flush slider is open.
Also mildly so after
many uses even when
not opened to flush
but it does not
smell like poo;
except when actively pooing.
I often use two

control aromas.

Must Find an Acceptable
Dump Location
for the “Black Water”.
Not always easy to find.
They provide sewer holes
and water specifically
for rinsing.

Dump Stations
Usually Charge a Fee.
Campgrounds Sometimes
Charge a Fee
if you’re not staying.

Vault Toilets are free
and stinky anyway,
but there’s not a way
to clean it out with water.
Sludge Will build up inside
if not rinsed out regularly.

Not socially acceptable
to dump in public toilets.
It’s big and bulky,
loud, splashy,
and overly smelly.

We are immensely happy to be free of a cassette toilet and the messy dumping stations, the loaded smells and splashing, the frequent time-consuming, additional worrying efforts in finding a dump station that is appropriate and that doesn’t cost so much.

Have a good night on the trail, wherever you are on your journey.
