Wrappon Green Portable Toilet

When exploring and camping the bathroom routine has always been a chore. Unless at an established campsite with toilets there’s usually been a little extra work before hand to dispose of, well the crappiest part of backpacking, camping, or overlanding.

A small trowel and a few minutes searching you might find the perfect spot. Hidden away from anyone else and far enough away from camp. Then there’s the digging, squatting, and digging.

When my wife and I started camping together she wasn’t having it. She had two requests. A toilet and a shower. Now I wasn’t keen on packing around a toilet. That’s what I had my trusting orange trowel for. It was clear if she was going to be joining me there needed to be a toilet.

We started with the Luggableloo, the bucket and the bags. This worked but I had constant worry about the bags. The bags had a seal much like Ziploc bags at the top.

The next option was a Dometic cassette toilet. The toilet was nice. Seating was more comfortable and more sturdy than the bucket. The toilet functions by having a clean water tank which flushes waste into a black water tank. The downside to this toilet is the black water tank was a constant concern it may rupture while off-road and cause a significant mess inside my habitat on the back of my truck. I have had no one mention this has happened to them. It was just my concern. Also, cleaning the tank at the end of a trip or middle was less than desirable. Trying to put the waste inside a toilet was not something I enjoyed ending a trip on.

A while back at one of the Overland Expos I was in the AT Overland booth as part of their display. Mario Donovan had brought their new Summit camper and it was outfitted with beautiful Goose Gear cabinets, but what caught my eye was a green aluminum box tucked away inside. I asked about its contents and Mario exclaimed it’s the best toilet option out there. I was intrigued, but having not used it I would have to withhold my own opinion.

A few months ago I reached out to S.E. Technologies in Colorado who imports the toilet from Japan. They agreed to send us a sample unit for review and to give feedback. The unit arrived quickly and was packed well to prevent any damage. The toilet has a quick reference guide to get you started and a manual. The toilet came with a supplied AC power cable. S.E. Technologies also sent two bag kits and two boxes of coagulant.

The Wrappon Green Toilet was developed in Japan as a response to disaster relief. Since its development has found uses for construction (like in tower cranes), recreation (boating, rv’s, and Overlanding), and emergency response (flood, tornadoes, earthquakes).  

The toilet is self contained in a green aluminum box as mentioned before. The toilet measure 18.1 x 17.3 x 10.6 inches. The toilet has a single carry handle. The top lid corners have plastic stacking guides. These are there for stacking up to four toilets for storage. The corner guides seem to help protect the lid while storing in the truck.

Under the top lid you find the seat. There is no roll loaded when it arrives. Under the unit you find the legs folded to the middle. There is a reinforcement bar secured inside and two thumb screws to attach the reinforcement bar between the folded legs.

On the bottom is also where the power cord attaches to the toilet. This is a four pin plug which appears to be proprietary. The control to flush the toilet is stored under the bottom cover. The control is corded and there is more than enough cord provided. 

The toilet has a rated weight capacity of 220 lbs. To test this I pushed the limits a little. I weigh in at 186. My three boys and I weigh 295 together. With permission from my wife we collectively weigh 323 lbs. The toilet had no issues on level ground supporting the weight. If you were to have the toilet on uneven ground I can not say it would have performed the same. 

The toilet has a continuous roll which is sealed after each flush to create a separate bag of waste. The bag is cut off the roll and deposited under the unit. The bags are 5 layers which eliminate odor and keeps the entire system sanitary between uses. There are approximately 50 flushes per roll of bags.

To load the bag you must first remove the seat. There you find a white film guide with a single tab on opposite sides. Remove the white film guide. Here you will seat the plastic roll. After you have it set you can replace the film guide and then remove the blue plastic wraps from the roll.

The plastic bag is then pulled up about 1 Foot. You then push the grasped bag into the toilet. Next you will use the provided tool to push the plastic down bag into the mechanism which pulls and seals the bag.

Next you turn the toilet on and allow it to run a initialization. Once done the toilet is ready to use.

Before use you are to add a bag of coagulate. It is suggested to use wet wipes instead of paper. After finished you press the flush button and the toilet pulls the bag down seals and cuts it off leaving it to be disposed of beneath the toilet.

To test the toilet I used water and a muffin to simulate waste. The coagulate was added first. Then the muffin and the water. The flush button was pressed and the bag was deposited beneath for disposal. No leaks, no odors, no mess.

The real test came from a 7 day trip out west to Wyoming with my entire family of 5. The toilet had high expectations to work as we brought no other means for backup. Foolish, but optimistic.

To run the toilet I did not have the dc power cable or lithium battery accessories available. I was provided the ac cable and knew I could run it from the Tacoma’s bed outlet. The cable is approximately 11′ long. Because of this I did not have any concerns. Before I left for the trip the power was checked to make sure there would be no issues with the power connection.

The toilet was stored toward the tailgate for quick access should the need arise. Our Tacoma is outfitted with a Quickpitch privy on the passenger side of the Habitat. I installed it there intentionally. Having the privy installed on the passenger side keeps it off the roadway and shoulder. It places the user away from traffic should someone need to use it while traveling.  

The first time setting up at camp was extremely easy. The lower cover removed, the legs were set and reinforcement was attached. With the power cable installed the toilet was ready to go. The thumb screws tend to need a significant amount of screwing to put in and unscrewing to take out. Having read Margy Green’s blog post and spoke with her directly I knew this a head of time. As she suggested I kept the thumb screws in a separate box with the coagulant, extra bags, wipes, and power cable.  Margy has named her toilet the Wizard of Poo. Give her blog a read.

 

Over the course of our week of travel we used the toilet daily and had zero issues. The toilet functions as designed.

Not carrying waste the entirety of the trip made me feel more comfortable while traveling off-road. There was less worry about a potential spill or ruptured tank inside the bed of my truck where my camper, clothes, and food are stored.

Not having to haul unusable water is significant. The Dometic and other cassette toilets require the water in the storage tank.

There is also ZERO odor from the unit. Because the bags are sealed and removed there is no odor emitted. Whether using or storing inside a camper odor is a thing of the past.

The waste bags were placed in a our MSA tire trash carrier in a trash bag. The toilet was sanitary and ready to travel the next morning. The bags and trash were disposed of appropriately the next day.

Another consideration is the weight. I have been attempting to continue cut weight from the Tacoma over the years. The Dometic was approximately 12 lbs. This is without water. The unit I have holds approximately 5 gallons. At 8 lbs per gallon of water you are looking at a total weight of 52 lbs. Once waste is added the weight continues to go up.

The Wrappon Green toilet weight is approximately 26 lbs. This is half in weight savings from a “loaded” cassette toilet.

The only negative to this toilet is it’s upfront cost.

The toilet is listed by S.E. Technologies at $989 from their Amazon store. One of their distributors, OK4WD, lists the toilet for $854. A standard cassette toilet will run anywhere from $100 – $250. A composting toilet can run up to over $900. To compare against the composting toilet the neither require water. The difference is the composting toilet still requires the urine and solid waste tanks to be dumped. The solid waste tank can become very heavy and cumbersome to manage for some based on others opinions.

Who is going to want this toilet? The avid traveler will find the positives outweigh the cost. Those who only take one or two weekends to camp may not benefit from the cost. 

Another component which should be considered is the ability to build this unit into vans, travel trailers, and campers. If the unit was to be removed from the box the toilet could be put on a slider or built into a bin. The versatility would allow those in the industry to expand their ability to put a smaller unit into their campers as the height and depth would be dramatically reduced from other options on the market. 

For us we find this solution to be the best out there for the many reasons we listed and they definitely out way the cost.
