Waterless Dry Flush Toilets for RV, Camping, Off-Grid & Home Care

After each use, the waste is sealed inside a disposable liner bag. Once the bag is ready to be removed, take it out according to the user manual and dispose of it in accordance with your local waste-disposal regulations.

In many outdoor, RV, camping, emergency-use, and home-care situations, sealed bags may be handled similarly to other bagged sanitary waste. However, disposal rules can vary by city, campground, RV park, care facility, and state, so users should always follow local regulations.

Yes. The refill bags are universal for compatible Modiseal / Modiwell automatic sealing dry flush toilet models.

You do not need to choose a different refill bag for each toilet model. Each refill roll contains 30 bags. Refill kits may also include two rolls plus 60 packets of coagulant, providing up to 60 uses in total.

Before purchasing, make sure the refill product is for Modiwell / Modiseal automatic sealing dry flush toilets rather than unrelated portable toilet bags.

Refill replacement frequency depends on the number of users and how often the toilet is used.

Each refill roll contains 30 bags. A 60-use refill kit contains two refill rolls plus 60 packets of coagulant. For light personal use, one refill roll may last longer; for family, RV, camping, emergency, or high-frequency use, refills will need to be replaced more often.

If the toilet is used for both urine and solid waste every time, refill consumption will be higher. If a reusable urine tank is used for liquid waste, refill bags can last significantly longer.

Yes. All Modiseal / Modiwell dry flush toilet models include refill bags and coagulant for up to 60 uses when purchased with the toilet unit through official channels.

This means customers can start using the toilet after setup without needing to purchase refill bags separately for the first uses.

If purchasing from a third-party, used, open-box, or non-authorized seller, please check the product listing carefully to confirm what is included in the package.

Replacement refills are currently sold under the Modiwell brand on Amazon. To find them, search for “Modiwell refill bags” or “Modiwell dry flush toilet refill” on Amazon.

Because Modiwell is part of the supported product line, Modiwell-branded refill products are the correct replacement consumables for supported Modiseal / Modiwell dry flush toilets.

The refill cost depends on the refill package, purchase option, current pricing, and whether a reusable urine tank is used.

Based on current Modiwell refill information, the estimated consumable cost ranges from approximately $0.47 to $0.70 per use. Bag-only refills generally cost less per use than refill kits that include coagulant.

For users who frequently urinate, using a reusable urine tank can significantly reduce refill consumption. In a typical two-adult scenario, the estimated consumable cost can be under $2.00 per day when the urine tank is used properly.

Actual cost may vary depending on refill pricing, promotions, shipping, taxes, personal usage habits, and product model.

For frequent urination, using a reusable urine tank can help reduce refill bag consumption.

Instead of using a new sealed bag for every liquid-only use, the urine tank allows liquid waste to be collected separately, emptied, rinsed, and reused. This can significantly reduce the number of refill bags used over time.

For best results, use the toilet, refill bags, coagulant, and urine tank according to the user manual.

Refill bags should be stored in a cool, dry place and kept sealed before use.

Original Modiwell refill rolls are vacuum packed. Unopened refill rolls can be stored for up to 18 months. Once opened, we recommend using the refill within 3 months for the best sealing and handling performance.

Avoid storing refill bags in direct sunlight, high heat, high humidity, or areas where they may be punctured or damaged.
