When you are exploring in an RV, dealing with toilet water and waste can take up space, time, and attention. Traditional RV toilets often require water tanks, plumbing, and black water disposal. A waterless dry flush toilet can simplify the setup and make restroom use easier in compact RV spaces.
What's a Modiwell Waterless Toilet?
The Modiwell waterless toilet uses automatic sealing technology to manage waste without flushing water. The system feeds the bag, seals waste with heat, and helps reduce direct contact with waste. This makes it a practical option for RVs, vans, and other spaces where plumbing or a black water tank is not ideal. Modiwell refill bags are made with biodegradable materials, so disposal should still follow local waste rules.
Easy to Install in Your RV
The Modiwell waterless toilet is designed for RV and vehicle use. Unlike traditional toilets that require water and waste plumbing, it is simpler to place and power.
- No water pipes needed: Since it does not use flushing water, you do not need to connect freshwater or black water plumbing.
- Flexible power options: The LE-310 supports an AC wall charger and a 12V cigarette lighter charger. Its built-in 57.72 Wh lithium battery also supports Approx. 100 uses on a full charge.
- Compact size: The LE-310 folds to 17.5" x 16" x 10.75" and weighs 16.5 lbs, making it easier to fit into small RV storage areas, toilet boxes, or multi-purpose layouts.

How to Install and Use Your Modiwell Waterless RV Toilet
Setting up and using the Modiwell waterless RV toilet is straightforward. For detailed instructions with diagrams, check the Modiwell toilet product manual.
- Open the support legs: Pull the legs on both sides outward until they click into place. The bottom baffle opens automatically.
- Charge it first: Use the included charger. The battery indicator will show the charging status, and it is best to fully charge the toilet before first use.
- Install the refill pack: Open the top, remove the cushion and pressure ring, place the refill pack with the arrow facing up, remove the strap, and reinstall the pressure ring.
- Prepare the film: Pull out about 8 inches of film from the outside, fold the top over, and push it into the toilet.
- Place the guide: Push the guide straight down until there is no resistance, lift it back, and replace the seat cushion.
- Turn it on: Press the power button. The toilet will complete a short self-check and display the battery level.
- Seal it for the first time: Press and hold the Start button for more than 2 seconds to start sealing. The process takes about 2-3 minutes and ends with a beep.
- Add coagulant: Tear open one small coagulant packet and pour it into the bag before use.
- Seal after use: After using the toilet, press and hold the Start button to seal the waste bag. Remove the sealed bag from the bottom and dispose of it according to local rules.
Tips for Using Your Modiwell Waterless RV Toilet
These habits can help improve daily use and extend the service life of the toilet.
- Use compatible bags: Modiwell original refill bags are recommended for reliable sealing and fit.
- Use coagulant when needed: Coagulant helps absorb liquid and reduce the risk of leakage during handling.
- Clean the surface regularly: The toilet does not need water flushing. Wipe the seat and exterior with a damp cloth as needed.
- Maintain the battery: If the toilet will not be used for a long time, store and recharge the battery according to the manual.
- Keep the RV ventilated: Good airflow helps keep the interior fresher, especially in small RVs and vans.
