Dry Flush vs. Cassette vs. Composting Toilets

Feature Modiwell Dry Flush (Our Choice) 🏆 Composting Toilets 🍂 Cassette / Black Tank Toilets 🚽
Odor Control 100% Odorless. Heat-sealed Mylar bags instantly lock away waste and smell. Zero lingering odors. Prone to bugs & smells. Requires constant venting. One mistake with moisture leads to foul odors and gnats. Harsh chemical smells. Relies on strong blue drops to mask the smell, which worsens in summer heat.
Water Usage Zero. Saves 100% of your fresh water tank for drinking and showers. Zero. No water needed. High. Uses 0.5 - 1 gallon per flush. Drains your fresh water tank fast when boondocking.
Waste Disposal 100% Hands-Free. Toss the sealed bag in any normal dumpster, just like diapers. Messy. Dealing with human waste mixed with peat moss. Emptying the liquid urine jug every 2-3 days is a nightmare. The "Walk of Shame". Carrying a sloshing 40lb box to a dump station. High risk of disgusting splashback.
Maintenance Quick & Clean. Swap a fresh cartridge in under 2 minutes. No scrubbing, no chemicals. High Maintenance. Requires daily cranking (stirring), managing coco coir, and maintaining a 12V exhaust fan. Gross & Tedious. Requires frequent chemical deep cleaning to prevent solids from calcifying.
Best For Boondocking, Vanlife, Premium RVs & Off-Grid Living. (Anyone who values time and hygiene). Eco-enthusiasts willing to manage human compost. Campgrounds with full hookups and dumping stations.

FAQs

How much does a dry flush toilet cost to run?

With an ongoing cost of under $2.00 per day for two adults using a urine tank, running a dry flush toilet is highly cost-effective, with standard or eco-friendly refills ranging from $0.47 to $0.70 per flush depending on whether you purchase full cartridge packs or bags only.

What is the warranty policy for the toilets, and do you offer any extended coverage?

Every purchase comes with a complimentary 18-month limited warranty by default. If any quality-related issues arise within this 18-month period, we will fully cover the cost of warranty repairs or servicing. For added peace of mind, you can also purchase our Extended Accident Protection Plan at checkout to safeguard your product against accidental damage.

Are dry flush toilets environmentally friendly?

Yes, they do not use any water to flush water, and can often combine coagulants to reduce the overall environmental impact associated with traditional sewage systems. At the same time, dry flush toilet consumables are specially made with biodegradable bio-waste bags, which are certified by the EU EN 13432.

What are the power supply specifications for the LE-310 and R1808 models?

The LE-310 is powered via an AC Charger, while the R1808 supports dual options with Hardwired (9V–30V) and AC Charger, though it is highly recommended to keep the R1808 connected to a constant power supply for optimal operation.

What is your return and exchange policy for this product?

We offer a 30-day return and exchange policy specifically for any quality-related issues that arise within 30 days of purchase.

What is a dry flush toilet?

A dry flush toilet is a self-contained, waterless toilet that seals waste automatically after each use. There is no water supply needed, no plumbing connection, and no black tank to empty. Modiwell dry flush toilets use heat-sealing technology to wrap waste into an airtight, odour-proof bag that can be safely disposed of similarly to household diapers, in accordance with local laws and regulations.

Where do you ship and how long does delivery take?

Modiwell ships free of charge to the United States, Canada and Australia from local warehouses in each region. Orders are processed within 1 to 2 business days and typically delivered within 3 to 7 business days. A tracking number is sent by email once your order has shipped.
