What to Look For Before Buying

Choosing a composting toilet means balancing your rig’s power and your available space. You should pick between manual units or those with electric mixing. Think about how long you stay off-grid, as this dictates the waste capacity you actually need.

Check Space and Dimensions

Measure your bathroom area before you buy. Toilets have different footprints that affect how much legroom you have. Check the height to ensure you are comfortable while sitting.

Value Power and Ventilation

Decide if you have a 12V system for a fan. Fans are excellent for keeping compost dry and keeping smells away. If you lack power, look for passive ventilation or bag-based systems.

Rating Waste Management Capacity

Think about how often you want to empty the bins. Full-time travelers should prioritize units with larger capacities. Weekend users might prefer smaller, lighter units that are easier to stow.

Verify Ease of Maintenance

Assess how easy the unit is to clean. Look for LED indicators and removable bins. Units that use bags often make disposal much cleaner.

Frequently Asked Questions

Do composting toilets smell in a small van?

When installed well, they are almost odorless. The diverter keeps liquids away from solids, which stops the main source of smells. Fans also help move air away from the user.

How often do I need to empty the liquids?

It depends on your usage. Most van toilets need emptying every 2 to 4 days for liquids. Larger units can last much longer for two people.

Can I use any bag for the solids bin?

Many models take standard bags, but check the manual first. You want to ensure the bag does not block the mixing mechanism.

Is a 12V connection mandatory?

It is not required, but I highly recommend it. Electric fans handle moisture and odors much better than passive systems.

Are they difficult to install in a campervan?

Installation is simple if you have basic tools. Most units just need a small vent hole and a secure mount to the floor.

🎯 Final Verdict

The OGO Origin is my top pick for van builds because of its small size and electric agitation. It offers a modern, premium experience in a very compact package. If you need more capacity and a proven history, the Nature’s Head Vehicle Kit is my favorite alternative.
