CompoCloset Cuddy Composting Toilet FAQs:

Where can I use / install Cuddy?

Anywhere you like!

Cuddy is perfect for vans, campervans, RVs, Tiny Homes, off-grid cabins, boats and more.

Its size, shape and portability make it suitable for anywhere you need to poop.

Do composting toilets smell?

No, composting toilets do not smell when used properly. They will not stink out your van, boat, tiny home, camper, or cabin.

The compost material looks and smells earthy—like a forest floor. When emptying the toilet, there is no unpleasant odor, unless you’re one of those rare folks that don’t like forest floors.

What type of material should I use in Cuddy’s solids bin?

A compost medium like coconut coir is our favorite. Add the medium the solids bin covering the bottom of Cuddy’s agitator arms, and off you “go”!

What are the power requirements for Cuddy?

Smart LED (pee level signal) – 9v battery (not included)

Internal fan – 12v hard-wired

The fan connector is a standard 5.5 x 2.1mm male DC power cord.

This will be attached to a 4ft length of cable that can be wired into your van’s power supply with a 1A fuse.

It is also possible to get a cigarette lighter connector, or wall plug as well.

The Best Composting Toilet Medium (and How to Use It):

Choosing the right composting toilet medium is key to ensuring your composting toilet operates smoothly and odor-free. In this guide, we’ll focus on the best composting mediums for composting toilets like Cuddy (with an agitator) and Cuddy Lite (without an agitator).

Spoiler Alert: We think the best compost medium for Cuddy is Coco Coir. We’ve found and users agree that it’s the best for moisture control, odor reduction, and ease of use with the agitator.

For Cuddy Lite, you can use any compost medium that is readily available. Cuddy Lite’s simple design allows flexibility in using a variety of organic materials for layering, depending on availability and personal preference.

Now, let’s start with the basics.

What is a Composting Medium?

A composting toilet medium is also known as a bulking agent, composting material, cover material, litter or substrate. In all of these cases, it is a substance added to a composting toilet to aid in the breakdown of waste and to prevent odors.

The compost medium can be any organic carbon rich material such as sawdust, animal litter, coconut coir, hemp, animal bedding, or sphagnum peat moss (although we don’t recommend peat moss because of it’s questionable sustainability). These help to create air pockets in the compost pile, which is necessary for aerobic decomposition.

What Does the Composting Medium Do?

The composting medium does several important jobs:

• Balances the carbon-to-nitrogen ratio in your waste.
• Absorbs excess liquid to keep the solids at the right moisture level.
• Traps air pockets, which are essential for aerobic decomposition (preventing bad smells).
• Covers the waste to reduce odor and improve aesthetics.

All of these things add up to making your toilet smell less and just make it a happier place for both people and those good bacteria.
