How does a DRY FLUSH Tiny House Toilet Work?

those of you wondering what the heck a “dry flush” toilet is (as they are still relatively “new” to the house scene), Derek “Deek” Diedricksen (author of “Microshelters”) shows you one in use, during his stay at “Ovida” one of the many tiny house rentals through “Getaway Boston”, located within 90 minutes of downtown Boston, MA. This will also soon be fully toured and featured in another video. These units are also frequently used in RV as well.


  1. COOL! ?Yes,… shit ? is alsof a tiny house issue!??? So THANKS for the dry toilet YouTube video Derk. ? Keep up the good work,.. info and tips coming on youtube.? Before you know the Netherlands had 1 tiny house more! ??With Dry toilet ??????

  2. I wish you had added some form of dirt or colored liquid to the bowl/foil so that we could have seen how it handled the waste. Just a thought.

  3. Definitely a one person household toilet with no little house parties going on. Thanks for the demo. I always wondered how messy a job it would be to remove and clean composting toilets contents with and without separation of liquid from solid waste. For a household of five. And how often.

  4. I just looked at the site- less than $600 for this toilet, FAR less than a composting or incinerating toilet. It’s kinda like an automated version of what I did in a bucket when i was homeless. Very affordable.

  5. That was interesting, I don’t recall hearing about that kind until now.
    I’m finally in my Tiny (10×12+7×6 riser). I’m using a composting loo, I add peat moss to the bucket & dump it weekly on its own composting pile. I’m getting the Tiny ready for winter living. Starting with insulating the floor with Roxual & foil vapor. The outside temp this morning was 43* and inside was 50*… I could’ve burned heat (propane with sunflower radiant). Good seeing again

  6. This may be a crazy question, but you have to remove the foil bag thing out of the toilet? And where do u dispose of it??? I live way out in the country so ill take an outhouse anyday!

  7. The sawdust in a bucket emptied frequently is cheapest and probably easiest to deal with. It’s so funny, considering how many people deal with cats with a litter box how they can’t deal with something that comes from their own body. Emptied a few times a day, nothing to overflow or plug up (assuming you’re composting sufficiently for hygiene), my grandparents used a commode in their house for decades without incident.

  8. It’s a diaper genie.

    I love toilets. Like, I watch the segments just to see how they get the bathroom set up so that it doesn’t feel like a water coffin. The kitchen is important, but there’s nothing worse than feeling cramped on the crapper. Some of the older/historic houses on the south side have the toilet either too close to the wall or too close to the tub. And you even wonder if it was put in after build. But these houses/apartments have stained glass windows…go figure.

    I think the weird thing about the composting bucket is it makes you feel poor, I mean uncivilized. A house toilet isn’t just a chair. It’s a porcelain sculpture. We in western society would think we should be upgrading our potties, not moving back into the backwoods. But I think those Japanese toilets are too busy. I don’t need a carwash for my butt. This thing though…it’s like for people that break their flush addiction. If you have to go this way, the incinerator toilets look like the better deal.

  9. An interesting alternative, but one of the reasons not to have a flushing toilet is to be ecologically responsible….I can’t see how filling Mylar bags that will take centuries to decompose is a better alternative.

    I’ll stick with the Home Depot bucket and sawdust….
