eco toilet

What makes a ECO TOILET and what does it look like from the inside?

Today it’s about the inner values of an eco toilet. What does it look like from the inside and how does the composting toilet actually work?

Principle of Eco Toilet

For easier understanding, I would like to explain the basic features of the composting toilet, eco toilet or dry toilet using the following sketch:

elements of a composting toilet sketch

The typical eco toilet basically consists of only 3 main elements:

  1. Urine Separator Insert (from Separett, TROBOLO, Kildwick, S+T etc.)
  2. Solids container (usually a bucket)
  3. Urine canister (or bottle)

You can also replace the latter with a hose and then drain the urine into a larger tank.

You can find more details about the separators, containers and canisters in the shop.

Can I build a Eco Toilet myself?

If you have a little bit of manual skill, you can build the eco toilet yourself.

If you pay attention to a few things, you’ll never want to miss it again.

You can either find some really good instructions on the net, or just write me.

By the way, I will be presenting self-construction projects of my customers here from time to time in the near future.

To clarify the possibilities for you, you should download my little collection:

Just click on the following picture and download “The 10 best tips for composting toilets.” Currently available in German language. I am currently working on the translation.

Which Eco Toilet to buy?

By the way, there are also ready-made waterless toilets. So you don’t have to build them yourself. In the following I have divided them into categories:

Ready made Eco Toilets for fixed use

For garden houses and TinyHouses there are quite respectable variants, which look quite similar to the household toilets.

Here Separett has made a name for itself with the “Villa 9010” – or as a simpler variant – with the “Weekend 7010“.

Disadvantage: Both need a separate urine tank, which has to be placed outside the toilet. Therefore they are not the first choice for mobile applications such as mobile homes/ boats/ yachts etc.

Eco Toilets for mobile use

For mobile applications there are currently 3 American versions available for purchase and recently also something from Germany.

The American ones are the ones from NaturesHead and the AirHead.

You can see that they have been developed primarily for boat building.

They look very similar to the typical sea toilets.

However, these two have an interesting feature: they can also compost.

The “fresh solid matter” is stirred in by means of a crank and thus mixed with the already older solid matter. So you usually don’t need any additional litter to dry the solid.

These toilets are also quite expensive, look modest and have to be completely removed to empty the solids.

But you don’t need any bags and you can go up to 3 weeks without emptying the solids.

Since recently there are also 2 from Germany.

These come from master carpenters who know a lot about furniture construction.

Carpenter’s Eco Toilet

Luxury Composting Toilet

This eco toilet captivates by its optics. It is complete with toilet seat, solids bucket and urine tank in the housing.

I myself have currently installed it in my motor home and am testing it.

With the comfortable standard toilet seat and the compact dimensions, it is currently the smallest on the market.

You can find more information about the carpenter toilet here.

Dimensions:

width=39 cm / depth=45 cm / seat height=45 cm (total 49 cm)

incl. 10L urine container on board.

You can also get them in the shop.

In Vario

On the one hand the kit In-Vario (for self-assembly and self-painting)

Here with e.g. Separett 501 dividing insert.

(It fits also the 500/400 from Separett – but unfortunately not the Kildwick).

I have also recorded a video for this.

Measurements:

width=44 cm / depth=48 cm / seat height=45 cm

incl. 10L urine container on board.

You can also get them in the shop.
