Cuddy is the waterless composting toilet for RVs and vans. It keeps #1 and #2 apart and lets nature dry out the solids, so there’s no sewage and no blue juice. Pour the urine into a regular toilet. Two people bag and bin the solids every 2–3 weeks.

Weeks, not days.
Two people get 2–3 weeks of full-time use between empties. Turn the handle to mix and dry; you never open the bin to do it.

No smell. Skeptics included.
Two bits of nature do the work. First, urine and solids never meet, so no sewage forms. Second, coco coir mixes with the solids and the handle turns air through it, so they dry out and start to break down. Dry doesn’t stink. Think old dog poo on the lawn: you wouldn’t stick your nose in it, but it doesn’t smell.
“I was skeptical that any composting toilet wouldn’t smell. But, wow! The Cuddy has NO ODOR at all.” — kevin

Win back space.
No tank, no plumbing, no dedicated toilet corner.
“Takes up way less space and smells less than our old black water toilet. It stores under a bench seat.” — Steve & Ki Dunn
Emptying takes minutes.
When the light says the urine bottle is full, lift it out and pour it into a regular toilet where local rules allow. Lift the solids bin out of the front, bag the dried solids and put them in the trash. No hoses, no dump station.

Your build, your call.
Composting makes a little heat, and heat makes moisture. The built-in 12V fan and carbon filter handle that when you keep it portable. For a permanent install, vent it outside or upgrade to the venting filter, so the mix never gets too wet.
Commitment issues?
Same.
Cuddy is two toilets in one. Heading out for a month? Use the agitator bin: it composts and dries, with 2–3 weeks between empties for two people. Weekend away or friends staying over? Swap in the no-agitator bin, line it with a bag and it works like a Cuddy Lite. Bag it, tie it, bin it. Get both bins in the Cuddy 2-in-1 for $879.
“Depending on our trip duration we leverage either the ‘mixer’ bin for longer trips (1 month or more) or the ‘catch’ bin for shorter adventures.” — Steve & Ki Dunn

Finish the build
The science, simply explained
How it
actually works

Urine diverted automatically
The built-in diverter sends liquid to a dedicated 1.7-gallon bottle. Liquid and solid never mix.

Coco coir soaks it up
A layer of coco coir in the solids bin absorbs moisture and starts drying solids out.

Agitator mixes & dries
A front-mounted handle turns the agitator, mixing in the coir so solids dry out and shrink.

Fan + carbon filter = no smell
A 12V fan pulls air through refillable activated carbon. Odor goes away from the seat, not toward you.

Reviews of Cuddy
Common questions
We’ve heard it all
How does a composting toilet work?
It keeps #1 and #2 apart, so no sewage forms. Coco coir mixes with the solids and Cuddy’s handle turns air through them, so they dry out and start to break down. More: how a composting toilet works.
Do composting toilets smell?
Not when urine and solids are kept apart and the solids stay dry. The 12V fan draws air through a carbon filter to keep it that way. More: why urine diversion stops the smell.
How often do you empty a composting toilet?
For two people using Cuddy full time, the solids bin every 2–3 weeks. The urine bottle whenever the light says it’s full.
Where do you empty a composting toilet?
Bag the dried solids and put them in your household trash where local rules allow, or finish composting them at home (that takes 6–12 months). Empty the urine bottle where local rules allow. More: where and when to empty a composting toilet.
What do you put in a composting toilet?
Coco coir. It mixes with the solids, soaks up moisture and helps them break down. More: choosing a composting toilet medium.
Can you put toilet paper in a composting toilet?
Yes, but it takes up space, so you’ll empty a little sooner. Tear the squares apart before they go in so they don’t wrap around the agitator. More: toilet paper in a composting toilet.
Does a composting toilet need a vent?
Cuddy’s built-in fan and carbon filter are enough if you move it around. If it’s installed for good, vent it outside or fit the upgraded venting filter, which needs no drilling. Either way the coir mix stays dry enough to work.
Cuddy vs Nature’s Head vs OGO: what’s the difference?
All three are composting toilets with a 12V fan. The differences show up when you buy, install and empty them.
Price: Cuddy $850, Nature’s Head $965, OGO Origin $985.
Emptying: Cuddy’s solids bin lifts straight out. With Nature’s Head you unbolt the unit, carry it outside and tip it over a bag.
Install: Cuddy’s carbon filter means no drilling if you keep it portable; Nature’s Head and OGO need an outside vent.
Two toilets in one: swap in Cuddy’s no-agitator bin and it works as a separating toilet.
Space: Cuddy’s lid opens flat against the wall, and it shares one footprint with Cuddy Lite and the S1 Dry Flush toilet.
What is the difference between Cuddy and Cuddy Lite?
Cuddy has an agitator and composting system, better for full-time and extended use. Cuddy Lite uses bags instead, with no agitator — simpler and great for part-time use.
Not sure composting is your thing?
Prefer never to
see it at all?
Cuddy composts. The S1 Dry Flush seals each use into its own bag at the push of a button — same urine diversion, no composting knowledge required. It comes with its own battery, or as the S1 12V that wires into your rig. Or add the S1 Adapter Kit to the Cuddy you already own.
