Manuals & guides

The diverter does the work
Urine goes one way, solids the other. Because they never mix, there is no sewage and no smell, no chemicals needed.

Agitation & Aeration
The front-mounted agitator mixes solids. Faster breakdown, smaller volume, fewer empties — two people get 2–3 weeks of full-time use.

Nothing to see here
A solid cover hides the solids bin, and the largest drop zone in its class means no awkward aim. The LED urine indicator tells you when to empty, so you never find out the hard way.

Install it or take it with you
Cuddy mounts flat against any wall and the lid still opens fully — it fits where others can't. Or leave it loose and carry it to the next campsite.

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 accelerates breakdown
A layer of coco coir in the solids bin kickstarts natural composting and controls moisture.

Agitator mixes & dries
A front-mounted handle turns the agitator, cutting volume and speeding up decomposition.

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
Does it smell?
No. Composted material looks and smells earthy, like a forest floor. Urine and solids are separated so no sewage smell is ever created.
Do I need to drill holes in my van?
No. Cuddy works without venting, thanks to its built-in fan and carbon filter. If you use it full time, we recommend venting it outside, or adding the Venting Carbon Filter if you’d rather not drill.
What goes in the solids bin?
A small amount of coconut coir or wood shavings to start the composting process. No chemicals, no special products.
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.
