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 delivery.

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.
