The Toilet That Will Change the World!

Living full-time on the road and in the woods has put our survive and thrive priorities up front – instead of paying someone else to take care of our needs, the basics take up a good chunk of our time.

Shelter, food and water, hygiene, animal care, and the big one – the bathroom.

Toilets in all of their incarnations symbolize a place of urgency and importance, it is the throne after all.

Our bathroom is a scant 2 ft. x 3 ft. — So you can imagine the challenges we have had building our biddy in a bus!

We have spent MONTHS researching options for a mobile commode! Everything from Ed Begley’s composting Envirolet toilet, to the more compact/travel versions, like Air Head, and Nature’s Head (which cost over a grand after you get all the proper accessories). One thing we learned from our composting toilet option: Strong odor results from solid waste mingling with urine. Separate the two and the smell is waaaaay limited. We nearly went with the composting option – but since we are not stationery for more than a few days tops, and we use our toilet often, there really wouldn’t be enough time to fully break down the material as compost requires — The smell is limited, but not eliminated.

We also tried the chemical RV option for awhile and porta potty (which we soon nixed – it’s why most RVs smell the way they do). They are just plain awful to operate or empty — and, in our opinion, are only good for very limited or emergency outdoor use.

We even looked into incinerator toilets (warning, that link goes to a very graphic video explaining how incinerating toilets work)! They leave very little waste, but take a lot of power to run and aren’t the safest option for a traveler in motion.

Thanks to the DryFlush waterless, compact, travel toilet, we have been able to go three-plus months on the road so far without any smells, leaks, or awkwardness! It also costs half what a compact composting toilet will set you back.

DryFlush Toilet

The DryFlush is a space-aged emerging technology perfect for our small bathroom space in A Little Further. The unit is compact, yet the seat size is standard. The DryFlush toilet flushes via an electrically charged battery that can be charged via any average 120v outlet. We charge it by plugging it in to an extension cord once a month (we have gone longer, but if you let the battery sink too low, we have found that the unit uses more power and cartridge resources — so charge when you can!). There is also a solar option!

Once you’ve done your biz, you hit the button and listen for the swirl – the device sucks the air out of the chamber, shrink wraps the waste, then compacts it into the bottom half of the unit, where it is stowed inside of a larger bag that, once full up, you simply pull out (without having to see, touch or smell anything offensive!) and dispose of in a trash bin (no awkward moments at a dump station or rest stop!).

There is seriously NO ODOR. AT. ALL. And you don’t need to cut a hole to vent it out of your vehicle!

Check out a video of exactly how this revolutionary toilet works!

There’s been no leakage and aside from the twinge of guilt for taking up landfill space (the DryFlush company is currently developing a biodegradable/compostable option!) the unit has saved us many painful cold, late night trips to the woods or the restroom.

Our only criticisms of the unit is that a little extra TP is needed to soak up the liquid as the unit gets fuller to avoid being forced out with the air — but the positive is that you can use any type of toilet paper, unlike in a typical chemical or enzyme plumbing system found in most RVs that require special toilet tissue that is expensive and not too skin-friendly. Also, the cost of the cartridges that hold your waste can be steep for a full-time user, but this company is relatively new, and we have been told that in addition to the biodegradable solutions they are working on, they are also redesigning their cartridges to be more affordable, since they are a disposable item. Our suggestion to DryFlush: nix the plastic and try a fabricated (perhaps coated?), recycled cardboard for the ring!

The DryFlush is a truly incredible invention that can solve so many problems for travelers, disadvantaged areas with poor plumbing and sanitary conditions, military units, off-grid homes, boaters, ice fishers, you name it!

The DryFlush retails for $420 at this time and comes with one battery and one refill installed. Three refill bags retail for $49.95.

Until we land and are able to build out our ultimate dream bathroom – the DryFlush is our choice for the road!

    This is a great discussion about waste management in a limited space but there is a lot of misinformation and opinion to wade through. Someone has mentioned the C-Head and I am the designer and manufacturer of this product. I would be glad to answer questions regarding waste management in general and the C-Head specifically with respect to tiny houses or any other application with the same problems. I can gladly answer questions about the ethics and methods of your waste management, how a urine diverting composting system works exactly and I can address installation issues. I truly believe that the urine diverting composting toilet is the wave of the future in so many areas.

    1. Kerry

      Have a question regarding the dryflush toilet. We can’t afford to put a bathroom on main floor of our house. It will be hard for my husband to get upstairs to the bathroom so I was looking into this toilet to put in the sunroom off of the kitchen. Bad idea, so-so idea or good idea?

      1. Sandy Graves

        There is no reason that you couldn’t do that with a BoonJon (google it). I would get a wood grain model so that it looks like furniture. You don’t need to vent the BoonJon and there is no smell when closed and only a brief basement smell while using it.

  2. S. Sloan

    It’s a Litter Locker for people! I don’t have to see it to know it will work – I use a Litter Locker for my cat’s litter, and it does this exact same thing (only with a hand crank). No smell, empty it when full. I’m impressed!

    i just bought an ecojohn for my cabin in big bear, california. an incinerating toilet. man i love this thing. a little pricey at $3,995 but worth it. works perfect and very sturdy. these are supplied to the us army and marine corp. i have the propane model that also uses a small amount of electricty. we use the cabin about twice a month and usually it’s four of us. works like a charm. i was surprised by no odor. i really thought that would be a problem. anybody else have one??

      I too live in BBC, restoring a small vintage trailer, and developing a small garden nursery using off the grid tech…would like to connect. Roxanna

    I cant get my head around a plastic bag full of human waste, even if wrapped in plastic – because it wont stay that way for long, being thrown in a garbage bin and going untreated to landfill! Does anyone else have a problem with this?

    This would not be acceptable where I live.

    It does look like a nice tidy unit but I think I will go the composting route even though i dont like the look of them or an incinerator type.

    1. Brenda

      What’s the difference from a diaper genie. They have been out for years. Tons of households use them everyday. They go into landfills with the diapers that are not good either.

    2. Tania thorn

      I agree! I used to live on a boat so I get the need to think about these things, but poo in plastic bags in landfill? Ugh! Composting toilets way to go!

    3. Teresa

      Uh… how many people have pets and put their poop, untreated, in plastic bags and put them in landfills? Most people who will use something like this DON’T have pets, so what is the difference, really?

  5. Angela

    I could not use a product that prioritizes convenience over the environment. I hope the manufacturers are working hard on a biodegradable option.

  6. Richard Brunt

    I don’t think that is a very ecologically minded way to go. Untreated poop in a landfill (that bag will quickly break, by the way) is a health risk to sanitation worker and anyone else that comes upon it. It would also likely be illegal in some areas (like Canada). Why not just poop in a plastic bag then? Composting toilets are a better idea, and if cost is the big issue then you can build your own, as I detail on my site.

  7. Richard Brunt

    May I also add that replacement cartridges are $55 for 3. Each cartridge is good for 15-17 flushes. So you definitely can’t flush after each pee – that would get expensive quickly. Two people, flushing only for solids, will go through 2 cartridges per month. That is $440 per year! In 10 years, almost $5000 on toilet cartridges. Composting toilets have practically zero operating costs.

    1. Stephanie

      Your calculations are based off of 10 years. This company is new and growing. Chances of them still charging that amount even in a half a year from now is not very likely. Just keep an eye on the product if it’s tickling your fancy future tiny home builders. Compost toilets still a great idea.

  8. crittergarden

    This seems like an AD! Sounds perfect. I’ll have to see someone else promoting it before I’ll believe it wasn’t written by the marketing team!

  9. Brad

    There is an error here. It says composting toilets reduce but do not eliminate odor. This is 100% false. I’ve used several composting toilets, including the Airhead and Nature’s Head, and there is absolutely no odor whatsoever. The toilet featured is much more expensive in the long run because of the bags. Plus you are creating garbage, and contributing to the problem instead of helping solve it. If you can’t afford a compost toilet then build one, but don’t use this wasteful and expensive contraption!

  10. Camb-Loos

    It looks like a neat and compact toilet but looking how you’ve described it (almost perfect, without smell and all that), it just becomes questionable, you know? And as you said, using it is relatively easy but we wouldn’t go for that knowing that it isn’t very eco-friendly.

  11. Suzanne

    Did you know that it is illegal to dump solid human waste into landfills? People do it all the time with diapers even though if you look at the packaging it says to remove and flush the solid waste into the toilet. Furthermore, this is not “off the grid.” Sure you don’t get a water bill but you still have to rely on a manufacturer to supply you with refills and you still need electricity. A composting toilet or an electric incinerator (solar powered) would be truly off the grid.
    I just don’t like the idea of putting poopie in a case (biodegradeable or not) and then another larger case and then sending it to the landfill. I don’t think that it’s a tiny “twinge of guilt” that most people feel about this subject.
    Finally with a composting toilet eventually you make up for the cost because once you buy/make it you don’t really need anything else if you use a solar option or make one yourself. With this unit you have to perpetually buy these refills… Forever…. Just like your double bagged poopie will be around in that landfill…

  12. echo59

    i’m late to this party…sorry.
    some ?s for everyone:
    if the bags were bio would that make a diff? if they were compostable and could just be thrown on the compost heap would that help? if the cost per “flush” was around 5 cents would that work? oh, and if you didn’t need power?
    just wondering….

  13. Nick

    How could anyone support this terrible toilet? First of all you can get a composting toilet at the same size, if not smaller. I can’t believe the the price on this thing, it is NOT “half the price of a composting toilet. Sure maybe compared to some retail composting toilet models… but I don’t need some fancy machine to stir my poop and look pretty. That’s not even mentioning the operating costs. This is probably somewhat of an upgrade from a conventional toilet but the problem with our society comes from making complex issues out of simple solutions. The average simple composting toilet is effective, has no smell, and does the same thing.

  14. Wxm

    I agree with earlier comments. Bad form to discard human waste in a refuse facility. The pathogens in animal waste and human fecal matter are not the same. Diapers in the dump are a travesty for multiple reasons. Let’s work to reduce the mess that we are leaving, not just move it around.

  15. Anna

    It’s a packaging toilet. These have been on the market for decades.
    I doubt this is only $420, but perhaps it is. I had an early version of this called the Pacto-San. No one would buy it except crane operators and prisons where they do drug tests. I ultimately did give it to the Boston Building Materials Cooperative.
