It’s lightweight, weighing only 34 pounds, and it’s simple to set up.
The toilet, adapters for both 110V and 12V electricity, and all parts for direct venting and connecting the liquid drain into a greywater system are all included in the package. The tank is large enough for an average-sized household to utilize for three weeks.
2. Sun-Mar Excel Self-Contained Composting Toilet
When seeking an environmentally-friendly toilet, the Sun-Mar Excel Electric Waterless Composting Toilet is worth considering.

Three individuals or a family of five can fit in the self-contained tank.
3. Nature's Head Self Contained Composting Toilet
Efficiency is crucial when it comes to small composting toilets. To begin with, the rubbish being composted should have no odour. The compost should be safe to handle after that. The liquid component should finally be evaporated.
All of this appears to be accomplished by the Nature’s Head model, and it does so without generating any compost byproduct odours. The toilet separates liquid waste into its container using a dry composting approach.
4. SUN-MAR GTG Portable Toilet
When looking for a compact, portable toilet that composts, the Sun-Mar GTG Composting Toilet is worth considering. The self-contained GTG generates the same compost as other, much larger toilets, unlike other travel versions that still need to be emptied into a sewer.
The GTG is a 12V-powered waterless toilet with a fan. It separates liquids from solids and divides them into two containers that are easier to remove. It weighs just under 30 pounds and measures 24 inches deep by 15.75 inches wide and 19.8 inches tall so that it will fit in most compact houses, RVs, and campers’ restrooms without difficulty.

It has a detachable liquid jug that separates liquids from solids. It features a 12-volt fan and a 5-foot vent pipe for exhausting gases.
6. Sun-Mar Compact Self-Contained Composting Toilet
The Sun-Mar Compact is a smaller version of Excel and is better suited to small families with up to two persons. It’s not as big as the Excel model, but it’s a lot more appealing. It features a low-profile, stylish design that will fit into most compact areas. Sun-unique Mar’s Bio-drum is used to shrink it. It has a smaller diameter in the front and a larger diameter in the back.
The drum is stirred using a single agitator handle. It extends from the unit’s front. The fact that it disappears into the unit’s body is a beautiful space-saving feature that Nature’s Head versions don’t have. This model’s front-operated handle makes it excellent for small areas, but it’s not perfect for short-length restrooms. This composting toilet is one of the tiniest on the market.
7. Reliance Products Luggable Loo Toilet
The Luggable Loo is about as simple as a toilet for your compact house can get. It’s just a 5-gallon bucket with a plastic toilet seat affixed to the top. The genius of it is that these buckets are sturdy enough to hold the majority of people. They’re also made to be completely airtight. It is ideal for something that will use to store garbage.

Composting Toilet Buying Guide
Check to see if a composting toilet will function in your area before buying one. Self-contained and split/central systems are the two sorts, and while they both break down waste, they operate differently and have distinct needs.
A self-contained system:
A self-contained system includes a tiny toilet with a removable tank and a liquid drain for waste removal. Some self-contained systems are portable, making them ideal for camping vacations or boat journeys. They may also be set up in areas where plumbing isn’t available, such as a workshop or garage.
As the name implies, the whole composting process takes place within the toilet. When the tank is filled, remove it and empty the manure. Freshwater tanks or supply lines are occasionally included in these systems to flush waste into the chamber below.
Central System or Split System:
Composting toilets that are connected to a central or split system are comparable to regular toilets. They link to a network of pipes that transport trash to a central bio-drum, hopper, or tank, where it is composted. The garbage is churned in the hopper, which allows it to decompose while simultaneously releasing odorless fumes. When the tank reaches capacity, empty it as if it were a self-contained toilet.
Because split systems require a hopper, which is generally put beneath the toilet, they are significantly more costly than self-contained composters. The hoppers are helpful since they enhance the amount of compost that can store. These composting toilets are an intriguing option for permanent off-grid or environmentally aware houses, but their design makes them unsuitable for mobility.
Composting toilets take up a little more room on the floor than regular toilets, and they don’t have a separate holding tank to deal with. Look for a compact model with a smaller waste tank if you’re building a tiny house or boat.
If room for a split system is available, the greater holding capacity may be worth the expenditure. Adding a hopper to areas like garages and cottages is occasionally possible. Installing the tank outside is a possibility in warmer climes.
Composting vs. Portable:
Although a portable toilet and a composting toilet may appear identical, there are several key distinctions. Microorganisms break down human waste in composting toilets. They distinguish between liquids and solids, allowing bacteria to feed on the organic chemicals found in both. Humanure can be used to strengthen a lawn or garden after it has been composted. The composting process produces a byproduct that fertilizes the soil and provides nutrients to plants.
That is not the case with a portable toilet. Everything flows into one waste tank with portable toilets, and liquids and particles are not separated. Even after adding enzymes and deodorizer to the tank to break down particles and mask odors, the final product must still be disposed of through a sewage or septic system. While portable toilets are convenient for camping and boating, they may not be ideal for permanent housing such as mobile homes and compact houses.
The Capacity of Tank:
When looking for the best composting toilet, consider how many people will be using it. It will help you estimate how much of a tank you’ll need. Manufacturers frequently categorize this based on the size of the family and the intended usage.
A split system with a large tank, for example, might manage the waste of three adults or a family of five, but a self-contained composting toilet with a five-gallon tank would suffice for one adult. The theory is that by appropriately designing the tank, waste will have enough time to decompose into manure before it fills up.
Use of a Utility:
The aerobic bacteria that break down the waste require a lot of oxygen, abundant in the air. A fan that pulls air into the tank and across the waste is powered by electricity in specific composting toilets. It also vents the carbon dioxide produced by the bacteria into the atmosphere. Many functions with a 110V system in the home, while others work with 110V AC and 12V DC from a vehicle or RV battery.
A water line may be required for a composting toilet. While it may seem paradoxical, water-using composting toilets use considerably less water each flush than a typical household toilet. There are also waterless and non-electric versions available, so consider your utility arrangement and household budget when selecting a toilet.
The gases must be produced by the microorganisms in a composting toilet evacuated. Otherwise, smells may develop, and the bacteria’s function may deteriorate due to a lack of oxygen. The blower that draws air into the tank on some versions also drives gases out of the vent, removing odors. After each use, add organic materials, such as sawdust, on top of the waste to cover the scent while allowing the bacteria to break down the solids.
