More Details on Our Top Picks
Nature’s Head Structure Kit with Composting Toilet – All-Inclusive, Waterless, Self-Contained System for Off-Grid Living
This all-in-one kit from Nature’s Head stands out for its comprehensive design, making it particularly well-suited for those seeking a turnkey, waterless solution for remote cabins or tiny homes. Compared to the Sun-Mar Excel, which relies on a more complex composting mechanism, this kit offers a simpler, self-contained setup with large capacity and minimal maintenance. While the durable marine-grade construction ensures longevity, the system’s bulkiness and the need for manual tank emptying can be downsides for very tight spaces or users preferring less frequent handling. Its low power consumption and included accessories make it a reliable choice for off-grid living, though initial assembly may challenge some users. Overall, this kit suits those prioritizing ease of installation and high capacity, despite some size and maintenance considerations.
Pros:- Complete all-in-one kit simplifies setup and use
- Waterless operation eliminates plumbing needs
- Marine-grade materials ensure durability in harsh environments
- Large capacity reduces frequent emptying
Cons:- Requires manual emptying of tanks, which can be cumbersome
- Bulky design may not fit very small spaces
- Initial setup involves some assembly effort
Best for: Individuals or families needing a durable, all-in-one composting toilet for off-grid cabins or tiny homes with high use demands
Not ideal for: People with extremely limited space or those expecting very frequent use who prefer a more lightweight or automated system
- Capacity:2.2 gallons urine tank, 60-80 solid uses
- Power:Low energy consumption
- Installation:Easy, no plumbing required
- Material:Marine-grade construction
- Included:110V AC adapter, vent, installation kit, coco coir
Our verdict“This kit is ideal for off-grid users who want a reliable, high-capacity, all-in-one composting toilet with straightforward installation, accepting some size and manual handling tradeoffs.”
OGO Origin Composting Toilet – 12V Electric, Urine-Diverting for RV & Van
The OGO Origin offers a sleek, space-efficient solution for RV and van owners seeking a modern, electric composting toilet. Its compact dimensions, at 15″x16″, make it ideal for tight mobile setups where space is at a premium, unlike the larger Nature’s Head kits. The electric push-button agitator simplifies maintenance and enhances user convenience, while the urine-diverting feature helps control odors and reduce tank capacity. Compared to the Sun-Mar Excel, which requires more space and has a more traditional setup, the OGO’s minimalist design prioritizes ease of use in confined environments. Its reliance on 12V power means it needs a reliable power source, limiting use in very remote areas without solar or battery backups. This pick is best for those prioritizing ease and modern aesthetics over high capacity or heavy-duty use.
Pros:- Compact size ideal for tight mobile spaces
- Electric push-button agitator simplifies operation
- Urine-diverting reduces odor and tank size
- Modern Scandinavian design enhances aesthetics
Cons:- Limited capacity for multiple users or frequent use
- Requires consistent 12V power, which may not be available everywhere
Best for: Vanlifers or RV travelers needing a compact, modern composting toilet that’s easy to operate with electric assistance
Not ideal for: Users expecting high daily usage or without access to reliable 12V power, as capacity is limited and power dependence is significant
- Dimensions:15″x16″
- Voltage:12V
- Urine Capacity:2.4 gallons
- Uses per tank:25-30
- Material:Polypropylene
- Includes:Mounting screws, power cable, venting hose
Our verdict“This toilet suits mobile dwellers who value space efficiency and modern features but can accommodate limited capacity and power requirements.”
Nature’s Head Self Contained Composting Toilet with Close Quarters Spider Handle Design
Compared with the Sun-Mar Excel, which offers fast composting but requires space and more complex setup, the Nature’s Head Spider Handle model emphasizes user-friendly operation and low maintenance, making it a solid choice for households or small groups. Its large capacity supports two users comfortably, and the no-odor design adds convenience for long-term off-grid use. While it requires some assembly and can be pricier than traditional toilets, its durability, backed by a 5-year warranty, helps justify the investment. This model’s key advantage is its simple, hygienic foot spider handle, which keeps hands clean, but its size and manual tank emptying may be drawbacks for those seeking ultra-lightweight options or minimal handling.
Pros:- No odor and low maintenance operation
- Easy to install and empty
- Large capacity supports two users
- Backed by a 5-year warranty for peace of mind
Cons:- Higher cost compared to traditional options
- Requires assembly and setup effort
- Size may be too large for very confined spaces
Best for: Off-grid households or small groups needing a durable, low-maintenance, large-capacity composting toilet
Not ideal for: Individuals seeking the lowest upfront cost or those with very limited space, due to size and setup complexity
- Brand:Nature’s Head
- Model Number:Spider Handle
- Number of Items:1
- UPC:853647003022, 689466406375, 733353592945
- Manufacturer:Nature’s Head Inc.
- Manufacturer Part Number:NH001
Our verdict“This model is best suited for users who value durability, large capacity, and ease of maintenance over initial cost and compactness.”
Sun-Mar Excel Composting Toilet
The Sun-Mar Excel emphasizes quick composting with its patented Bio-drum, making it ideal for off-grid sites where rapid waste processing is valued. Unlike the all-in-one Nature’s Head, which is more manual and larger, the Excel offers a streamlined, NSF-certified solution suitable for locations where traditional plumbing isn’t feasible. Its fast composting system reduces the need for frequent handling, but it may require additional space for the composting process itself and could come with a higher initial price tag. This model is best for those who prioritize certification standards and faster waste processing over minimal space or simplicity.
Pros:- Fast composting thanks to Bio-drum mechanism
- Easy to install and operate
- NSF certification guarantees safety and standards
Cons:- Requires space for composting process
- Potentially higher upfront cost
- Not suitable for traditional plumbing setups
Best for: Remote locations or small communities seeking fast, NSF-certified composting with relatively straightforward installation
Not ideal for: Individuals with very limited space or those who prefer a completely waterless, all-in-one unit with no composting process to manage
- Type:Self-contained composting toilet
- Certification:NSF Standard 41
- Features:Bio-drum for fast composting
Our verdict“This system is best for users who need quick composting with NSF certification and are prepared for a slightly larger footprint and higher initial investment.”
Nature’s Head Structure Kit with Composting Toilet – All-Inclusive, Waterless, Self-Contained System for Off-Grid Living
This all-in-one kit from Nature’s Head combines the advantages of the original model with added convenience, including a foot spider handle and full ventilation components. It’s designed for those who want a ready-to-install, waterless toilet without needing to source separate parts, making it especially appealing for tiny homes, cabins, or remote living. Its high capacity and low power needs are key benefits, but the manual emptying process remains a drawback for heavy or frequent use. Compared to the Sun-Mar Excel, which may require more space and setup, this kit offers a more straightforward, off-grid compatible solution with less complexity.
Pros:- Complete installation kit for convenience
- Waterless and off-grid ready, no plumbing needed
- High capacity supports extended use
- Includes hygienic foot spider handle
Cons:- Manual emptying required for tanks
- Setup can be complex for some users
- Limited capacity for very high-traffic scenarios
Best for: Remote dwellers or tiny home owners seeking a complete, easy-to-assemble solution with high capacity and low maintenance
Not ideal for: People expecting very high throughput or minimal manual handling, as capacity and handling remain user-dependent
- Capacity:2.2 gallons
- Solid Uses:60-80
- Urine Tank:2.2 gallons
- Power:Low energy consumption
- Made in:USA
Our verdict“This kit is a solid choice for off-grid setups requiring a comprehensive, high-capacity composting toilet with minimal fuss, accepting manual maintenance.”
Separett Villa Urine-Separating Compost Toilet
This model stands out for its urine-diverting technology, making it an excellent choice for those seeking a reliable, low-maintenance composting toilet that doesn’t require water or chemicals. Compared with the Nature’s Head units, the Separett Villa offers a higher capacity, reducing the frequency of emptying, which is a significant benefit for remote cabins or tiny homes. However, its bulkier design can be a drawback in very small spaces, and first-time users may need time to adapt to the urine separation process. Its low-maintenance operation and waterless design make it ideal for off-grid living, especially where water conservation is a priority.
Pros:- Waterless operation conserves water resources
- High-capacity design allows extended use
- Suitable for remote and off-grid settings
- No chemicals or complex maintenance required
Cons:- Bulky form factor may limit placement options
- Requires some adaptation for first-time users
Best for: Off-grid dwellers, cabins, or remote homesteads requiring a high-capacity, waterless toilet with minimal upkeep
Not ideal for: Small, tight spaces where bulky design hampers installation or for users uncomfortable with urine separation technology
- Type:Urine-Separating Compost Toilet
- Operation:Waterless
- Capacity:High-capacity
- Installation:Versatile (homesteads, buses, cabins)
- Maintenance:Low
Our verdict“This toilet is best suited for those who prioritize capacity and low maintenance over compact size in off-grid settings.”
OGO NOMAD Portable Composting Toilet – RV, Van, Camping & Boat, Waterless
The OGO NOMAD excels for users needing portability and simplicity in outdoor or mobile settings. Unlike the more stationary Separett Villa, this toilet is designed for frequent transit, with a lightweight build and no plumbing required. Its odor-free urine diversion system keeps liquids and solids separate, a feature that outperforms basic composting toilets in terms of smell control. The tradeoff is its limited capacity, making it less suitable for extended use or larger groups, and it relies on purchasing compatible compostable bags, which adds ongoing costs. For those who prioritize easy transport and minimal setup, this pick offers a practical solution.
Pros:- No electricity or plumbing required
- Lightweight and portable for travel
- Odor-free separation system
- Low maintenance and easy to clean
Cons:- Limited capacity requires frequent bag changes
- Dependent on purchasing compatible composting bags
- Not suited for long-term or high-volume use
Best for: Campers, boaters, and vanlifers who need a portable, low-maintenance composting toilet for short trips or remote outdoor use
Not ideal for: Large families or long-term off-grid residents needing high capacity and fewer bag replacements
- Brand:OGO
- Model Number:nom-bas-2024
- Number of Items:1
- Included Components:Compostable Bags (x2), Coco Coir, Cleaning Spray
- Item Type:RV Camping Toilet
- Best Sellers Rank:#16 in RV Toilets
Our verdict“This toilet makes the most sense for mobile outdoor enthusiasts prioritizing portability and ease of use over capacity.”
TROBOLO WandaGO Composting Toilet, Portable Outdoor Camping Toilet, Urine Diverting Dry Toilet with Height Adjustment
The TROBOLO WandaGO stands out for its portability and ergonomic design, making it ideal for outdoor adventurers who need a comfortable, spill-proof composting toilet. Its adjustable seat height and lightweight frame set it apart from bulkier options like the Nature’s Head or Separett Villa, providing enhanced comfort during extended outdoor stays. However, its limited number of uses per container and manual emptying process can be inconvenient for larger groups or longer trips. While lacking accessories or larger capacity, it’s a practical choice for solo campers or short-term outdoor use where portability and comfort are priorities.
Pros:- Lightweight and compact for easy transport
- Adjustable ergonomic seat for comfort
- Odorless operation
- Spill-proof, secure lid
Cons:- Limited number of uses before needing emptying
- Manual cleanup required
- No included waste disposal accessories
Best for: Campers and outdoor enthusiasts needing a lightweight, adjustable, spill-proof toilet for short-term use

- Dimensions:12.3” H x 15.0” D x 13.4” W
- Weight:10.4 lbs
- Seat Height Options:12.0” or 17.2”
- Supports:Up to 330.7 lbs
- Uses per Container:10-20 for urination, 8-12 for defecation
Our verdict“This portable option is best for solo outdoor users who prioritize comfort and portability over capacity.”
Nature’s Head Vehicle Kit with Composting Toilet – All-Inclusive, Waterless RV & Van Life System with Spider Handle
This all-in-one vehicle kit offers a complete solution for RV or van dwellers seeking a durable, odorless composting system. Its large capacity, marine-grade construction, and built-in venting system support extended off-grid use without frequent emptying, unlike smaller portable units. The included venting and installation kit simplify setup, but proper installation is essential for odor control — a potential challenge compared with the more straightforward Nature’s Head self-contained unit. Compared to the simpler self-contained models, this kit’s robustness makes it suitable for serious mobile use, though it involves a more complex setup process.
Pros:- Complete all-in-one installation kit
- Large capacity for extended use
- Durable marine-grade construction
- Odorless, waterless operation
Cons:- Requires proper installation for effective odor control
- May need frequent emptying depending on use

- Material:Marine-grade
- Ventilation:Built-in 12V fan
- Includes:Shell Vent, installation kit, coco coir
- Made in:USA
Our verdict“This kit is best suited for serious mobile travelers who want a high-capacity, durable, off-grid composting toilet system.”
Nature’s Head Self-Contained Composting Toilet with Foot-Spider Handle
The Nature’s Head self-contained model is a reliable choice for off-grid or camping applications, with a straightforward design that emphasizes ease of use. Its self-contained nature simplifies installation compared to the vehicle kit, though it tends to be heavier and bulkier than portable options like the WandaGO. The foot-spider handle adds convenience, but the limited detailed specs suggest it’s best for users who prefer simplicity over capacity or advanced features. When compared with the Separett Villa, this unit offers a more traditional, self-contained approach, though it might require more effort to empty and clean.
Pros:- Self-contained, easy to use
- Designed for off-grid and camping applications
- Includes a foot-spider handle for convenience
- Simple, straightforward design
Cons:- Limited detailed specifications
- Potentially heavy and bulky for portability
- Less advanced features compared to vehicle kits
Best for: Individuals or small families seeking a simple, reliable, self-contained composting toilet for off-grid or camping use
Not ideal for: Large groups or users needing high capacity and frequent emptying, due to weight and bulk
- Item Category:Toilet Seat
- Trademark:Nature’s Head
- Manufacturer:Nature’s Head Inc.
- Item Shape:Foot-Spider
Our verdict“This unit is ideal for those wanting a straightforward, self-contained composting toilet for remote or camping scenarios where simplicity matters.”
Nature’s Head Vehicle Kit with Composting Toilet – All-Inclusive, Waterless RV & Van Life System with Spider Handle
This all-in-one vehicle kit stands out for its comprehensive, ready-to-install design that’s perfect for extended off-grid adventures. Compared with the Separett Tiny, it offers a larger capacity, making it better suited for longer trips without frequent emptying. The integrated venting system ensures good odor control, although setting it up can be a bit complex for those unfamiliar with venting components. The inclusion of a coco coir bag simplifies initial setup, and the large capacity supports 60–80 uses, reducing the need for frequent maintenance. However, it requires manual emptying and the venting system might be tricky to configure correctly, especially in tight or complex vehicle setups. This pick makes the most sense for RV owners or vanlifers seeking a sturdy, off-grid toilet with high capacity and minimal plumbing needs.
Pros:- Complete all-in-one installation kit for quick setup
- Supports extended off-grid use with large capacity
- Waterless, no plumbing required, ideal for vehicles
Cons:- Requires manual maintenance and frequent emptying

Best for: Long-term RV or van travelers who prioritize a self-contained, waterless system with minimal plumbing effort
Not ideal for: Users seeking a lightweight, portable option for short-term camping or those uncomfortable with venting setup
- Capacity:Supports approximately 60–80 uses for solids and 2.2 gallons for urine
- Includes:Composting toilet, Shell Vent, installation kit, 9L coco coir bag
- Application:RV, van, camper, skoolie, overland vehicle
- Venting:Integrated ventilation fan
Our verdict“This kit is best for seasoned RV or van owners who need a reliable, large-capacity composting toilet that’s fully self-contained.”
Separett Tiny Self-Contained Urine-Separating Compost Toilet
The Separett Tiny excels in compactness and hygiene, making it a strong choice for tiny homes, boats, or limited-space RVs. Compared to the Nature’s Head Vehicle Kit, it offers a smaller footprint and more straightforward waste management, which is ideal for single or couple households. Its urine separation feature reduces odor and simplifies composting, although regular emptying of the urine and waste containers is necessary, which could become tedious over time. The system is odor-free and durable, but it’s less suited for groups or longer trips without frequent maintenance. This model is perfect for those prioritizing space efficiency and ease of use in small-scale off-grid setups.
Pros:- Waterless and odor-free operation
- Removable containers for easy waste disposal
- Compact, space-efficient design
Cons:- Requires regular emptying of urine and waste containers
- May need power for ventilation fan
Best for: Individuals or couples with small living spaces who want a hygienic, odor-free composting toilet requiring minimal plumbing
Not ideal for: Large families or those needing high capacity, as the small containers require frequent emptying
- Type:Self-contained composting toilet
- Urine Container Capacity:2 gallons
- Material:Biodegradable bags
- Design:Space-saving, modern
- Origin:Sweden
Our verdict“This toilet is ideal for small households seeking a space-saving, low-maintenance composting solution with excellent odor control.”
Xastro Complete Composting Toilet Kit with Urine Diverter & Toilet Seat
The Xastro kit offers a flexible, all-in-one DIY approach, making it stand out for users who want to customize their off-grid toilet. Unlike the fully integrated Nature’s Head options, this kit provides a larger opening and includes essential accessories like a urine diverter and a comfortable seat, enhancing user comfort. Its durable ABS surface resists odors and simplifies cleaning, but the pre-drilled holes may not fit all installations, requiring cutting and some DIY skills. Compared to the Separett Tiny, it’s more adaptable to different setups, though the installation process can be challenging for novices. This kit makes the most sense for those comfortable with assembly and seeking a customizable, durable dry toilet for various off-grid environments.
Pros:- All-in-one kit simplifies assembly
- Large opening improves comfort
- Durable ABS surface prevents odors
Cons:- Requires cutting and assembly, which can be challenging
- Pre-drilled holes may not fit all setups
Best for: DIY-minded users who want a customizable, durable composting toilet for cabins, boats, or off-grid projects
Not ideal for: Users seeking a ready-to-use, plug-and-play solution with minimal assembly or for those uncomfortable with cutting and fitting
- Opening Size:365mm x 276mm
- Material:Mirror-finish ABS
- Includes:Urine Diverter, Toilet Seat, Metal Filter Screen, Discharge Hose, Instructions
- Cutting Guide:Yes
Our verdict“This kit is best suited for DIYers seeking a robust, customizable composting toilet for various off-grid applications, willing to handle some installation complexity.”

How We Picked
The products in this roundup were evaluated based on several core criteria: performance in odor control and waste breakdown, ease of installation and use, durability of materials, maintenance requirements, and overall value for off-grid living. We prioritized systems that are reliable in remote settings, where access to water and power may be limited. The ranking also considers portability for different use cases—whether for tiny homes, RVs, or outdoor camping. Products with comprehensive features that streamline waste management and minimize odor were rated higher, while those with complex installation or higher ongoing maintenance were rated lower. Ultimately, these choices reflect the systems that best balance convenience, durability, and eco-friendliness for off-grid environments.Factors to Consider When Choosing Off Grid Composting Toilet System
Choosing the right off grid composting toilet system involves considering several factors beyond just features. It’s important to match the system’s capacity and design with your specific off-grid application, whether that’s a tiny home, RV, or remote cabin. Think about how much maintenance you’re willing to perform regularly, as some systems require more frequent attention. Also, consider the available space, power sources, and your environmental priorities, such as minimizing odor or reducing waste volume. Making an informed decision involves weighing these broader considerations against the features offered by each system.Capacity and Waste Management
Assess how much waste your system can handle between emptying sessions. Larger capacity units are better for extended stays or multiple users but tend to be bulkier and more expensive. Smaller, portable systems suit short-term use or single users but require more frequent maintenance. Consider whether the system offers easy access for cleaning and whether it separates liquids and solids, which can make waste management simpler and odor less invasive.
Power Source and Energy Needs
Determine if the toilet requires electrical power, and if so, what type—AC, DC, or battery. Electric models like the OGO Origin provide automated features but depend on a reliable power supply, which might not be feasible off-grid without solar or batteries. Manual systems eliminate power concerns but may demand more physical effort during use and cleaning. Balance your energy availability with the convenience of electric features when choosing.
Odor Control and Ventilation
Odor management is a critical factor in off-grid systems, especially in enclosed spaces. Urine-diverting models like Separett Villa help significantly reduce odor by separating liquids, while self-contained systems often rely on venting or carbon filters. Proper ventilation can improve comfort and reduce health risks, but it also requires space and sometimes additional components. Think about your setup environment and how much effort you want to put into odor control when selecting a system.
Ease of Installation and Maintenance
Some units are designed for quick setup and minimal ongoing maintenance, making them ideal for temporary or outdoor use. Others might involve more complex installation but offer greater durability or capacity. Consider your technical skills and the time you’re willing to dedicate to upkeep. Simpler, integrated systems typically require less hands-on effort, but may have higher upfront costs.
Portability and Space Requirements
Portability varies from lightweight, camping-specific units to larger, more permanent installations. If you plan to move your system frequently, look for models that are lightweight and come with carrying handles or wheels. For stationary setups, prioritize space efficiency and ease of access for cleaning. Keep in mind that bulkier models might need dedicated space but offer greater capacity and durability.
Frequently Asked Questions
How often do I need to empty an off grid composting toilet?
The frequency of emptying depends on the system size, number of users, and waste management practices. Typically, a well-sized system can go from several weeks to a few months before requiring emptying. Systems with higher capacity or those that separate liquids from solids often extend the interval. Regular monitoring and understanding your usage patterns will help you schedule maintenance without surprises, especially in remote or off-grid settings where access might be limited.
Can I install an off grid composting toilet myself?
Many composting toilets are designed for DIY installation, especially simpler, self-contained models. However, some systems with more complex venting or electrical components may require basic plumbing or electrical skills. Carefully reading the manufacturer’s instructions and ensuring you have the right tools can make installation smoother. In off-grid environments, choosing a model that aligns with your skill level can prevent frustration and ensure reliable operation.
How do I control odors in an off grid composting toilet?
Odor control relies on good ventilation, proper waste separation, and sometimes chemical or carbon filters. Urine-diverting models significantly reduce odors by isolating liquids, while self-contained units often incorporate venting fans or filters. Regular maintenance, such as adding carbon media or composting amendments, can also help keep odors in check. Selecting a system with built-in odor control features simplifies living in enclosed or semi-enclosed spaces off-grid.
What’s the best type of composting toilet for a small cabin?
For a small cabin, a larger, all-in-one self-contained system like the Nature’s Head offers durability and minimal setup, which is ideal for stationary use. Urine-diverting options like Separett Villa can also work well if odor control is a priority and space allows for venting. Consider your capacity needs and maintenance willingness—larger, more robust units are better suited for long-term use in a fixed location, providing reliable performance with less frequent emptying.
Are electric composting toilets worth the extra cost?
Electric systems offer convenience features such as automatic flushing, ventilation, and odor control, which can make off-grid living more comfortable. However, they depend on a reliable power source, which may not always be feasible off-grid without solar or battery backup. If ease of use and minimal maintenance are priorities, paying more for an electric model might be justified. Otherwise, manual or passive systems can deliver good performance at a lower cost and complexity.
Conclusion
For those seeking a reliable, all-in-one solution, the Nature’s Head Structure Kit remains the best overall choice, offering durability and straightforward maintenance. Budget-conscious buyers or those new to composting toilets will find the Separett Villa a smart, odor-controlled option that’s easy to install. If you prioritize portability, the OGO NOMAD provides flexibility for camping, boats, or temporary setups. For larger cabins or permanent installations, investing in a premium model like the Sun-Mar Excel ensures long-term performance. Ultimately, your choice should align with your off-grid lifestyle, space, and maintenance preferences.Flea & tick season Picks
