Composting Toilets



We will keep updating our FAQs. If there is an answer you need and you can't find it here, please get in touch and ask.

Is there a manual for Cuddy™ and Cuddy™ Lite with everything I need to know all in one convenient place?

Yes there is. Click here for all you need to know!

Is a Cuddy™ or a Cuddy™ Lite right for me?

There are obviously a whole range of variables and factors that we can’t account for in this general advice – please give us a call on 0447 047 237, we are happy to discuss what option might work best for you.

We also appreciate that no matter what general advice we give, users will have their own preferences due to their unique circumstances. Those opinions are as valid as ours.

Remember: Both Cuddy™ and Cuddy™ Lite separate solids and liquids, that is the most important thing. If you’re considering a travel toilet that does not separate, you will either have to use chemicals and a dump point, or you will be putting raw sewage into a bin or into the environment, please don’t do that.

Our general advice is as follows:

Full time use: Cuddy™ - You will have to empty less often, it will generally be more “pleasant”, and no need for plastic bags.

Regular use: Cuddy™ - After each trip you don’t have to worry about emptying the solids bin and the composting process will just continue. We have gone for 6 months between emptying our solids bin.

Irregular use: Could go either way, a Cuddy™ for the reasons outlined above, or a Cuddy™ Lite if you don’t want to or are unable to continue composting between trips.

Once in a blue moon: Cuddy™ Lite – Likely you will want to get all your kit cleaned and put away for next time.

Away with a group of people all using your loo: Cuddy™ Lite – With heavy use over a short period very little composting will begin, and from our first-hand experience you will end up with a bin full of very fresh deposits that won’t be pleasant to empty.

If you can’t make a decision, we suggest you go for the Cuddy™.

If you have A Cuddy™ and an additional solids bin without an agitator, you will have a Cuddy™ and a Cuddy™ Lite in one unit. It is the most versatile, fully optioned, and most affordable travel toilet in the world. It can adapt to any install, or portable application you can throw at it.

You can turn a Cuddy™ into a Cuddy™ Lite, but you can’t turn a Cuddy™ Lite into a Cuddy™.

Can I meet Cuddy™ face to face before I commit?

As with many types of modern relationships, we are mainly using online sales and distribution for Cuddy™.

If you are in or passing through Sydney please get in contact to make an appointment to see Cuddy at our facility in Rouse Hill.

You can also see a Cuddy in South Australia at The Dirt Off Road Campers in Mt Barker. Click here for their contact details.

We will be at the Newcastle Show in February 2024.

We are looking at some partners to help us have Cuddy™ on show around the country in 2024.

How does Cuddy™ work?

Put simply, he separates 1s and 2s at the source (that's you). The liquids go into a liquids bottle for easy disposal and the solids go into the solids bin to start the composting process. The key is to keep the liquids and solids separate, it's when the liquids and solids get mixed that it gets ugly.

Should I vent Cuddy™ externally?

You don't have to vent Cuddy™ externally. If you are using it for weekends or shorter trips, using the internal filter and fan will be fine. Cuddy™ was built to be portable and flexible for varied installations/uses.

The possible result of not venting externally (either outside of your van or just directly out the back of Cuddy™) is you may get a build up of moisture. It depends on many variables.

The moisture itself is not a problem, it means that the compost is heating up (that's a good thing) and the air temperature outside of Cuddy™ is most likely colder than inside, that can cause condensation.

If you are travelling for extended periods, having some type of ventilation is ideal. There are many options Cuddy™ gives you for how to vent, depending on how you are installing and using him. There are also some new retrofittable venting innovations on the way.

If you are venting externally make sure to get our fly screen and vent plug kit to stop any pesky flies making a home in your Cuddy™.

Please get in touch if you have any questions and we can work out what will work best for you.

How big is Cuddy™?

 Cuddy™ is 414 (H) x 384 (W) x 427 (D) mm. How small is that?? Well, it’s the same size as standard portable chemical toilets. So you can easily change it out if you have one. It’s at a comfortable height. Your toilet at home is probably about 440mm high.

Can I sit Cuddy™ flush against a wall?

You sure can. Right up against the wall to save space, we had to redesign the hinges to make it happen, but we got there! The 12V power plug is on the back under a lip to protect it, so the plug itself does not go outside of the Cuddy's™ measurements. You just have to get the wire to it. 

Can Cuddy™ stay in the shower with me?

Cuddy™ loves a shower but he is not "waterproof". He is designed to stop water ingress when showered on from above. The 12v power connection is in a recess at the rear of the unit so will also be protected.

We have a Cuddy™ Shower Cap available for shower time, you can splash around as much as you like!

What are the power requirements for Cuddy™?

Cuddy™ takes 12v, and we'll be shipping with the parts to be hard-wired via a 5.5 x 2.1mm plug, or you can plug it into the mains with an adapter. If you want to move Cuddy™ around that's easy too. You can get a cig plug, or merit plug adaptor or even a USB to 12V cable with a 5.5 x 2.1mm plug from here. He will go anywhere. Cuddy™ is very efficient - draws about 0.33 amps. 

It is ok if Cuddy is not connected to power all the time. If you store Cuddy in one place while travelling it could go without power and use it where there is power, or vice versa.

For the "pee full" indicator Cuddy uses a 9v battery, you will need to supply that.

How do I start the composting process?

Simple, a block of coco coir for about $6 and a some water is all you need to get the composting process going. You will need about 1/3 of a 15 litre block of coco coir and about 700ml of water to get the good stuff going. That is the only thing you will need every 3 weeks or so. 

How often/difficult is it to change the carbon filter?

Every 6-12 months and there's no expensive single use plastic cartridges. The filter holds 4mm activated carbon pellets you can find at places like this or this or most pet stores or amazon too.  You won't need too many, depending on usage you only need to change the pellets every 6-12 months, and you only need a couple of hand fulls each time.

How do I secure Cuddy™ in my travelling home?

Cuddy™ comes with 4 reinforced eyelets in the base that can be used to screw Cuddy™ to an appropriate base in your travelling home. They need to be pilot drilled first as not everyone will use them.

As Cuddy™ is portable you may choose not to limit it to one place. Just secure it anywhere while you are travelling, then place him in the spot with the best view when you arrive.

Where is Cuddy™ being made?

Cuddy™ is made in the USA using both U.S. and imported parts.

Composting Toilets

What about Toilet paper?

There are many differing opinions about toilet paper. Should you or should you not put it in the compost? Do you need a special type?

For what it is worth we recommend where possible to try to keep it separate from the compost mix, it takes longer to break down and can fill up the solids bin more quickly.

We appreciate that might not always be possible for whatever reason, so while any toilet paper will eventually break down, recycled single ply toilet paper seems to breakdown more quickly. 

Do composting toilets smell?

No! They will not stink out your van, boat, tinyhome or cabin! When emptying the loo, there is no unpleasant odour, instead, the composted material looks and smells earthy - like a forest floor.

Can you pee in a composting toilet?

Yes you can pee in a composting toilet. Our composting toilets are designed to separate the pee from the poop to eliminate any nasty odours.

Do you have to empty a composting toilet?

Yes, composting toilets need emptying but much less frequently than chemical toilets.

From our experience, they're much less unpleasant to empty than chemical toilets because they don't have an unpleasant smell and the solids simply resemble dirt.

How often do I empty my composting toilet?

The solids section of our composting toilets typically need emptying every 2-4 weeks depending on the level of usage.

You can look into the chamber to check the level and we would advise emptying when the chamber around two thirds to three quarters full.

The liquids container will need emptying every few days depending on how many beers you have at camp. 

Where do I empty my composting toilet?

If possible, to continue the composting process and to reduce landfill, bury the waste appropriately or add it to your own compost pile.

If you bury it please be responsible. Ensure it is at lest 100 metres away from a water source or camp site and at least 250mm down.

Solids from composting toilets may also be put in a biodegradable bag and disposed of in a regular rubbish bin*.

Cuddy™ is specially designed to make this step as quick and easy as possible. Liquids from composting toilets can be poured down a regular toilet or onto the nearest thirsty looking mature tree!

* All waste should be disposed of according to local regulations, and with care and respect for the environment and the other people who enjoy it.

Can I empty my composting toilet into another composting toilet?

Emptying your composting toilet into a bigger composting toilet - at a National Park, say - will not do any harm to the larger toilet.

If you do, please ensure you are tidy and respectful of the facilities provided by the park.

Can I put food scraps in my composting toilet?

We don't recommend this because food scraps will attract flies and other insects.

Can I put the compost in my garden?

Not until it has fully finished composting which will take several months.

While 'composting toilets' begin the composting process and reduce the volume of waste, the material needs additional time to kill off any bacteria and parasites. Joseph Jenkins has literally written the book on this -  'humanure handbook' and we would encourage any readers to refer to this as a reference.
