Every question
we actually get asked.

D 17″ × W 15.2″ × H 16.5″ — about the same as a standard portable chemical toilet, so you can swap one out directly. Most toilets at home are 15–17″ tall.

Not always. It depends whether you are full-time and where you live. For full-time use we do recommend it, and it is easy to do. You can vent outside or use the Venting Carbon Filter if you would rather not drill holes in your rig. Venting a Cuddy Lite is unnecessary.

The urine bottle is 1.7 gallons / 6.5 liters. The removable solids bin is 3.9 gallons / 14.7 liters.

When either bin is full. For two people that is usually 2–3 days for liquids and 2–3 weeks for solids.

Turning the agitator mixes your #2 into the coir and lets air in. That dries it out, keeps smells down and shrinks it, so you empty less often.

A 9V battery (not included) for the urine indicator light, and 12V hard-wired for the internal fan. The fan connector is a standard 5.5 × 2.1mm male DC power cord on a 4ft cable, wired in with a 1A fuse. Cuddy pulls only 0.1 amps at 12 volts.

ABS plastic, stainless steel and anodized aluminum. The agitator is anodized aluminum; its handle is marine-grade stainless steel and anodized aluminum.

Yes. Cuddy is water resistant, but keep it out of the direct line of spray and cover it while you shower. Seal any screw or rivet holes with silicone or vulkem caulking when you install it.

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

Most people who asked for an agitator-less version wanted to line the bin with a bag for easier cleaning, and some prefer the lower price. Here’s how it works: line the solids bin with a bag and add about an inch of coco coir. After each #2, cover it with roughly a cup of coir. After 8–12 uses, tie off the bag and bin it where local rules allow.

Yes — 8–9 US gallon bags fit. We recommend a compostable bag.

Cuddy Lite has the same seat, lid, covering plates, urine bottle, urine indicator light and footprint as Cuddy. It doesn’t have the agitator, fan or carbon filter, so the only power it needs is a 9V battery for the indicator light. Instead, you use the layering method: a bag in the solids bin and a scoop of coco coir after each #2.

The same as the Cuddy: 1.7 gallons of liquid, 3.9 gallons of solids.

Yes. The integrated handles let you grab and move it without pinching fingers or losing grip.

Yes. The S1 Dry Flush Sealing Toilet – 12V (No Battery) is the same S1 inside, without the internal battery. Wire it into your house (leisure) battery with a 10A fuse and it runs straight off your rig’s 12V system, so there’s nothing to charge. It runs on 12V only: it isn’t compatible with 24V systems and can’t be plugged into a household socket.

The S1 has waterproof connectors but the unit is water resistant, not waterproof. Keep it out of the direct line of water, remove it while the shower is running, or cover it.

Yes. The sealing mechanism can be removed and the solids bin lined with a regular bag — it then works exactly like a Cuddy Lite.

Two types: compostable and high-barrier. Each S1 and Adapter Kit ships with one roll of each so you can try both before ordering refills.

Don’t connect the S1 to power below 0 °C (32 °F). In cold weather, unplug it at the DC connector or the wall.

Approximately 25 uses per roll.

Bluetooth lets you tell the S1 which bag material you are using and apply mandatory software updates. If you would rather not have Bluetooth, this is not the product for you.

No, not when used properly. They will not stink out your van, RV, boat, tiny home or cabin. The composted material looks and smells earthy, like a forest floor.

Yes. Ours are designed to separate urine from solids, which is exactly what eliminates the odor.

Always check local rules. Usually solids can go in a biodegradable bag into a regular trash can, the same way diapers and pet waste are handled. Liquids can be poured down a regular toilet or onto the nearest thirsty looking mature tree.

Not until it has fully finished composting, which takes several months — usually 6–12, depending on temperature. It is safe to add the contents to a compost pile to carry on breaking down.

Yes. Blood and tissue are fine in either bin. We do not recommend putting pads or tampons in — they will not break down, they fill the bin faster and they make the agitator harder to turn.

Yes. When the solids bin is too moist, add more coco coir to bring the moisture level back. You may need to empty a little sooner than usual.

We do not recommend it — food scraps attract flies and other insects.

No. Bleach kills the bacteria the solids need to compost. For a deep clean use a 5:1 solution of water to vinegar, and clean the rest with a soft cloth and soapy water.

Email info@compocloset.com with photos or a video of the issue so we can see what is going on. It is our goal to solve every issue.

Close the covering plates before a #1. They keep urine out of the solids bin, and any drips on the plates run down a small chute into the urine bottle. Open them again for a #2. Sitting down rather than standing, and scooting forward on the seat, helps with aim.

White vinegar at roughly 5:1 water to vinegar. Pour some in after emptying, swirl and tip it out. Enzymatic anti-scaling products work too. Emptying and rinsing regularly keeps scale down.

They are most likely fruit flies. Sprinkle half a cup of diatomaceous earth over your coco coir, leave it a while, then agitate to kill eggs and larvae. Coco coir attracts fewer bugs than peat moss.

Usually it’s one of two things: the urine bottle sat full for a while, or some urine got into the solids bin. Empty the urine bottle, and add a splash of vinegar every other time you empty it. If the solids bin looks damp, add more coco coir. Check the one-way valve in the urine bottle too: it’s silicone and needs replacing every 6–12 months.

A little condensation is normal. Composting gives off warmth, and the moisture settles on the cooler lid and walls. Wipe it away, add more coco coir and turn the agitator regularly. Using Cuddy full time or somewhere humid? Vent it outside or add the Venting Carbon Filter.

No need to worry — mold is part of the natural composting process. Turn the agitator regularly to mix it back through the bin.
