Building your own camping toilet – The dry toilet without chemicals

For those who are often on the road in their campers, the topic „toilet“ is always one of those things. Some use the integrated classic chemical toilet, others an additional chemical toilet a la Porta-Potti. Others have nothing of the sort on board and are dependent on other ways of doing their business.

Especially when living space is limited, as in our VW Bus, it is not so easy to accommodate a toilet. Since we would like to be as independent as possible, sooner or later we needed at least an emergency toilet.

In the green nature our Günter is hardly noticeable

Personally, I don’t think much of chemical toilets, even though they would certainly be the fastest and easiest solution. But the possible smell of chemicals and also the emptying of the toilet cassette at special disposal stations made this kind of camping toilet rather uninteresting for us. 

On the other hand, there are the very minimalistic solutions to do one’s necessities: A bucket or a rack with a garbage bag that you use for business. But both Pragya and I were also less enthusiastic about this more „rustic“ way.  So you have to do it yourself to make the dream toilet.

Which camping toilet we decided on and how we built it, you will find out in this article.

The dry toilet as a camping toilet

After some back and forth we finally decided to build our own dry toilet. There are different variants, as you can read in detail at Camperstyle.

For the sake of simplicity, we decided against a separating toilet, where liquid and solids are separated. Meanwhile, I know that you can build the separation sets yourself, but in the first step, everybody starts small.
So that means that in our mobile camping toilet we collect the whole business in a container and then dispose of it. The advantage of this is that we can completely do without additional chemicals.

In addition, we are much more flexible with the dry toilet in the VW bus. Similar to the way dog owners walk their dogs, we can first cover our leftovers with rabbit litter and then dispose of them in the residual waste container. So we are not dependent on the disposal stations.

The box also serves as a stool and footrest

Basically, all we need is a bucket, compostable garbage bags, paper, and small animal litter to successfully complete our business. The small animal litter binds the remains and thus prevents it from stinking. Water is logically not used in the dry toilet.

Since our delicate buttocks naturally prefer some comfort, we still pack this dry toilet in a nice container. Many thanks therefore to my father for the great help.

Building the camping toilet yourself

First of all, you need a nice container for the nice camping toilet. We have decided on a wooden box with lid in the dimensions 50x40x44cm. It has a seat cushion and fits perfectly behind the passenger seat of the VW bus. In addition, you can use the box as a stool or as a footrest when closed.

In addition, there is a toilet seat in the dimensions 45x37cm*, which we found by chance at OBI and some wood as building material.

Among them are a few thin chipboards as inner lining and a pressed wood plate with 16mm thickness on which the toilet seat is mounted. Last but not least you will need a suitable bucket, which you can use as a collection container. We used my old diaper bucket, which my mother found at home. It’s nice to see that after more than 30 years the part is used as intended again.

In the first step you have to determine the dimensions of your crate to cut the pressed wood panel to size. We have adjusted it with the help of screwed wooden strips so that the plate is flush with the edge of the box. Adjusting the wooden plate can be a bit tricky, because the measurements of our wooden crate were a bit „skewed“ and we had to sand some corners again. For this reason we can’t give you any standard measurements at this point.

Careful measurement is important

Taking the right measurements of the camping toilet

As soon as you have cut and adjusted the pressed wood plate, you can start working on the hole of the toilet. We have cut the hole so that it is a bit bigger than the bucket, so that we can also remove the lid of the bucket in between or put it on top. Also, make sure that the hole fits the toilet seat. You can move the bucket in the box easier than the screwed toilet seat.

In the next step, we started with the interior lining of the box. My wooden crate is a rather typical wine crate and therefore visible below. Therefore we cut chipboards to size, which we can screw to the inside of the crate to create a certain odor and privacy protection.

I painted all the adapted wooden parts with wood stain and let them dry before we screwed them on the inside of the boxes and sealed the open joints with silicone.

After the paint and silicone had dried, the next step was to screw the toilet seat onto the pressed wood plate. Here you have to work a little bit with the play of the screw connection so that it fits perfectly on the hole and into the crate.

We screwed the additional wooden strips to the 4 inner angles of the wooden crate as a support for the pressed wooden plate, so that the pressed wooden plate including the toilet seat lies well on the crate and ends with the edge of the wooden crate.

All joints are sealed with silicone

In the next step, we had to fix the bucket under the toilet seat. To do this, we first screwed the painted inner lining to the box and took measurements with the bucket on the floor.
With the help of wooden strips, which we cut into light radii, we can now fix the bucket.

In the end, all that remains is the final adjustment and fixing of all components, and the ecological camping toilet for our VW bus is finished. In the bucket fit now biologically degradable 20-liter garbage bags and around the bucket around it, we can store in the box still the toilet paper as well as the rabbit litter.

We are more than satisfied with our camping dry toilet in the VW bus. It looks good, does not take up too much space, and even has some storage space for toilet paper, small animal litter and Co. It is perfectly stored behind the passenger seat and can of course be easily transported from A to B if desired. All in all, I expected more quality from the box itself, but for our purposes, it was still perfect.

We will test our dry toilet in the next few weeks and see how the smell is developing.  Therefore, we will first use a mixture of small animal litter and an absorber granulate* for binding, which should hardly cause any odors. Bark mulch would also be an alternative, I like the smell anyway. This way we don’t have to dispose of the compost bag directly, but can also stand self-sufficiently for a little longer. Later on, we will upgrade to a dry separation toilet, depending on the result.
