More Details on Our Top Picks
NOMAD by OGO Portable Compost Toilet – Camping Toilet for Truck Campers, Hunting Blinds, Car Camping, Primitive Camping & Boating, No-Electric, Waterless, Odor-Free Fits 8 Gallon Bags
This model stands out for its rugged durability and waterless, chemical-free operation, making it ideal for remote camping, hunting blinds, or boat trips where power sources are unavailable. Compared to the Nature’s Head, NOMAD is more straightforward, with no valves or complicated maintenance, but it relies on 8-gallon bags and a urine-diverting system that might require more frequent disposal in high-use scenarios. Its simple design minimizes moving parts, reducing potential failure points, yet the tradeoff is less built-in odor control than more advanced models like the Dry Flush. The lightweight, compact footprint allows installation in small spaces like truck beds or rooftop tents, and the no-electric setup appeals to off-grid adventurers. However, the bag system, while easy to change, can become pricey over time and lacks the odor containment of electrically powered options. This pick makes the most sense for adventurers needing a durable, chemical-free, off-grid solution with minimal setup and maintenance.Pros:- No electricity or plumbing needed, ideal for remote locations
- Odor-free urine diverting system with separation design
- Compact, lightweight, and highly portable for rugged environments
Cons:- Requires frequent disposal of bags, increasing long-term costs
- Less advanced odor control compared to electric models like Dry Flush
Best for: Rvers and outdoor enthusiasts who camp in rugged, off-grid environments without access to power or dump stations
Not ideal for: Casual campers or those expecting high daily use, as frequent bag disposal can become cumbersome and costly
- Capacity:8-gallon bags
- Waterless:Yes
- Power Source:No electric
- Material:Rugged materials
- Weight:Lightweight
- Designed For:Primitive camping, boat, truck bed
Bottom line: This is best suited for those who prioritize simplicity, durability, and off-grid independence over high-frequency use or advanced odor management.
Laveo Dry Flush Toilet – Waterless, Portable, Self Contained and Easier to Use than an Incinerating or Composting Toilet. Great for Tiny Homes, Vans, Boats, Camping, RVs and Off Grid, LDPE, White
The Dry Flush stands out for its full-size, toilet-like comfort and simple, chemical-free operation, making it a top choice for tiny homes, vans, or RVers who want a hassle-free waterless system. Unlike the NOMAD, which relies on bags, the Dry Flush uses sealed cartridges and airtight bags that are disposed of when full, offering a cleaner, more discreet experience. Its built-in fan ensures no odors escape, and the standard height seat provides comfort comparable to residential toilets—an upgrade over the more basic NOMAD for those prioritizing convenience. The tradeoff is the cost and limited number of flushes per cartridge, which can add up over time, and the need to purchase replacement cartridges. Its self-contained design and no-odor operation make it a clear winner for users seeking a reliable, easy-to-maintain portable toilet with a familiar look and feel.Pros:- Full-size, comfortable seat with familiar toilet height
- No water, chemicals, or complicated setup required
- Effective odor containment with built-in fan
Cons:- Cartridge replacements can be costly and limited in flushes
- Requires purchasing and disposing of sealed cartridges regularly
Best for: Tiny home dwellers, vanlifers, or RV owners who want a comfortable, low-maintenance, waterless toilet
Not ideal for: High-traffic use situations or for those concerned about ongoing cartridge costs, as it has limited flush capacity
- Capacity:15 flushes per cartridge
- Waterless:Yes
- Material:LDPE plastic
- Weight:27 pounds
- Installation:Floor mounted
- Battery:Not included
Bottom line: Ideal for users who prioritize ease, comfort, and odor control in a portable, waterless toilet for small spaces.
TRELINO Composting Toilet Evo S White, Portable Toilet for Camping & Outdoor, Odorless, 1.2 gal & 1.6 gal Capacity, 13 x 15.4 x 11.7 inches
The Trelino Evo S makes this list for its compact size and effective odorless operation, perfect for tiny vans, tents, or small cabins where space is limited. Compared to the more bulky Nature’s Head, this unit’s dimensions make it easier to fit into tight spots, yet it still offers a hygienic, separation-based composting process that avoids chemicals. Its capacity of 1.2 and 1.6 gallons is suitable for short-term use, but it requires more frequent emptying if used by multiple people. The sturdy ABS plastic construction ensures durability, and its German manufacturing quality adds confidence. The main tradeoff is that it lacks the advanced features of larger composters, like built-in fans or ventilation, relying solely on its separation and drying function to prevent odors. Still, for small-scale use and ease of cleaning, it is a smart choice for tight spaces.Pros:- Very compact and space-efficient design
- Odorless operation with separation and drying technology
- Made of durable, recyclable ABS plastic
Cons:- Limited capacity means more frequent emptying
- No built-in ventilation or fan for odor control

Its all-in-one design with a sealed composting chamber and foot-spider handle makes emptying quick and sanitary, and the odorless operation is maintained by a well-designed vent system. The major advantage is the five-year warranty and proven durability, but it’s bulkier and heavier, which could be a drawback for those needing portability or minimal installation effort. Its higher price reflects its durability and capacity, but it may be overkill for occasional campers or those with very limited space.Pros:- High capacity suitable for full-time use
- No odor with effective venting system
- Five-year warranty and durable construction

- Higher initial cost
Best for: Full-time RVers or off-grid users needing a high-capacity, durable composting toilet

Separett Villa Urine-Separating Compost Toilet | No Additives or Mixing Needed | High-Capacity Design | For Homestead, Schoolie, Cottage Use
The Separett Villa excels for off-grid homes, cottages, or tiny dwellings where chemical use is undesirable and space is limited. Its urine-diverting design effectively separates liquids, reducing odor and simplifying composting or disposal. Unlike the NOMAD and Trelino, which are more portable, the Villa is designed for stationary use and high-capacity composting, with no need for additives or mixing. Its high-capacity features make it suitable for multiple users over longer periods, but it is less portable and requires more space for installation. The high-capacity design and chemical-free operation appeal to eco-conscious users, yet it may be overkill for casual camping or short-term RV trips.

- Odor Control:Yes
- Additives:None needed
- Material:Durable plastics
- Use Case:Homestead, cottage, off-grid
Bottom line: Best suited for eco-conscious users with space for a stationary composting system and long-term use, rather than mobile or short-term applications.
OGO Origin Composting Toilet – 12V Electric Agitator, Urine Diverting RV Toilet for Van Life, Tiny Home & Boat – 15″ Compact, Odorless Off-Grid Toilet, No Black Tank
This compact design stands out for fitting into tight corners in vans, unlike larger models like the Nature’s Head. The electric agitator eliminates manual cranking, making daily maintenance effortless, which is a significant upgrade over traditional composters. Its urine-diverting feature keeps odors minimal and negates the need for a black tank, unlike less advanced systems. Compared to the TROBOLO WandaGO, it offers a sleeker aesthetic and quieter operation, but it does involve a higher upfront cost and requires a 12V power source. This model suits full-time van dwellers or tiny home owners seeking a low-maintenance, odorless setup without sacrificing comfort or style.

Nature’s Head® Self Contained Composting Toilet with Foot-Spider Handle
The Nature’s Head is a proven classic, favored for its simplicity and durability, especially for those new to composting toilets. Its foot-spider handle allows easy manual operation, comparable in function but less sleek in appearance than the OGO Origin. Compared to the TROBOLO WandaGO, it offers a more straightforward, non-electrical design, which appeals to off-grid purists but involves more physical effort. It is well-suited for users comfortable with manual handling and seeking a reliable, non-electrical system, though it lacks the modern aesthetic and low-maintenance appeal of newer models. Its tradeoffs include manual agitation and a bulkier profile, but it’s highly dependable and easy to service for long-term off-grid living.
Pros:- Durable, long-lasting construction

This portable toilet excels in outdoor settings, with lightweight design at just 10.4 lbs, making it easy to carry and store, unlike bulkier options like the Dry Flush. Its adjustable seat offers customizable comfort, and the urine-diverting system helps control odors without chemicals. The spill-proof design and secure lid make it ideal for travel, supporting up to 330 lbs, which surpasses many camping toilets. Unlike electric composters, it does not require power or chemicals, making it perfect for remote use. However, capacity for uses (8–12 defecations) means frequent emptying on longer trips.

- Adjustable seat height for comfort
- Odorless operation with urine-diverting system

How We Picked
The products in this roundup were selected based on a combination of performance, ease of use, maintenance requirements, build quality, and overall value. Priority was given to models that function well off-grid, with minimal water or power needs, and those that effectively control odor. We also considered user convenience, portability, and durability, as these are critical factors for RV users. The ranking reflects a balance between affordability and premium features, ensuring options fit different budgets and needs. Each product was evaluated for its suitability in an RV setting, with a focus on real-world usability and long-term reliability.Factors to Consider When Choosing Best Composting Toilet For RV
When choosing a composting toilet for your RV, it’s important to consider several key factors beyond just price. Your choice will depend on how often you travel, the size of your RV, and your comfort with maintenance routines. Understanding these factors helps avoid common pitfalls like underestimating capacity or selecting a system that’s too complex for your experience level. A well-chosen composting toilet can make off-grid living more comfortable and odor-free, but a mismatched model can lead to frustration and increased upkeep.Capacity and Size
Capacity determines how often you’ll need to empty your toilet, which impacts convenience and maintenance frequency. Smaller models are more portable and fit easily into tight spaces but may require more frequent waste disposal. Larger units offer extended use and are better suited for longer trips or multiple users. Consider your RV layout and storage space—compact designs are easier to install but might compromise capacity. Balancing size with your travel style ensures you’re not overwhelmed by frequent emptying or stuck with a bulky unit.
Ease of Use and Maintenance
Look for models that are straightforward to operate, especially if you’re new to composting toilets. Features like simple agitation mechanisms, accessible waste chambers, and clear instructions reduce hassle. Maintenance should be manageable without specialized tools; otherwise, it can become a burden. Some models have self-contained systems requiring minimal cleaning, while others need regular part replacements. Choosing a user-friendly system minimizes frustration and encourages consistent use, which is vital for odor control and hygiene.
Odor Control
Odor management is a primary concern in enclosed spaces like RVs. Many composting toilets incorporate venting systems, carbon filters, or urine separation to minimize smells. Urine-diverting models typically produce less odor because they keep liquids separate, reducing bacterial growth. Proper ventilation and sealed chambers also play a crucial role in odor reduction. Be cautious: poorly designed systems can lead to persistent smells, making your RV uncomfortable and potentially deterring use.
Power and Water Requirements
Most composting toilets are waterless, but some, like the OGO Origin, use minimal electricity for agitation or urine diversion. If your RV has limited power or you prefer off-grid solutions, opt for models that operate without electricity or water. Conversely, electric models might offer easier agitation or enhanced odor control but depend on your RV’s power supply. Assess your power availability and choose a system aligned with your off-grid capacity to avoid surprises during trips.
Cost and Durability
Prices vary from budget-friendly portable units to premium self-contained systems. Cheaper models often have simpler features and may require more frequent maintenance, while higher-end options tend to be more durable, with better odor control and easier cleaning. Consider long-term value: investing in a robust model might save money over time by reducing replacement and maintenance needs. Be aware that higher-priced units typically come with advanced features that improve overall user experience.
Frequently Asked Questions
How often do I need to empty a composting toilet in an RV?
The frequency of emptying depends on the model’s capacity and how many people are using it. Typically, smaller units might need to be emptied every few days, while larger, higher-capacity models can last a week or more between disposals. Regular monitoring and understanding your usage patterns are key to maintaining odor control and hygiene. Many models have indicator signals or simple ways to check waste levels, helping you plan your maintenance routine effectively.
Are composting toilets safe to use in an RV during cold weather?
Yes, but cold temperatures can slow down composting processes and affect odor control. Some models include insulation or heating elements to mitigate this issue, which can increase energy consumption. Proper ventilation and sealed chambers help prevent freezing and unpleasant smells. If you plan to camp in freezing conditions regularly, choose a model designed for cold-weather use or consider additional insulation to keep the composting process active and odor-free.
What maintenance does a composting toilet require on an RV?
Most composting toilets need regular removal of finished compost or waste, cleaning of the chamber, and occasional replacement of filters or other components. Some models feature self-contained designs that simplify maintenance, while others require more hands-on effort. Proper maintenance ensures odor control and prolongs the life of the system. Establishing a routine based on your usage will help keep the toilet functioning smoothly and prevent unpleasant surprises during your trips.
Can I use composting toilets in small RVs or trailers?
Absolutely, but size and capacity are key considerations. Smaller RVs and trailers benefit from compact, lightweight models that fit easily into tight spaces, like the NOMAD or TROBOLO units. These are designed for portability and minimal setup, making them ideal for limited space. However, ensure the chosen unit provides adequate capacity for your trip duration to avoid frequent emptying, which can be challenging in small or tight spaces.
Is a composting toilet suitable for long-term RV living?
Many composting toilets are well-suited for long-term use, especially urine-separating and self-contained models that minimize odor and maintenance. They eliminate the need for black tanks and water hookups, making them ideal for off-grid or extended stays. However, selecting a high-capacity, durable model like the Nature’s Head or Separett Villa ensures fewer emptying cycles and more reliable operation over time. Regular maintenance and proper waste management are essential for a positive long-term experience.
Conclusion
For most RV owners, the Nature’s Head Self Contained Composting Toilet offers a balanced mix of durability, odor control, and ease of use—making it the best overall choice. Budget-conscious travelers may prefer the NOMAD by OGO for its portability and waterless design, providing excellent value. Those seeking a premium, long-lasting system should consider the Separett Villa for its urine separation and extended capacity. Beginners or occasional travelers will benefit from portable, simple models like TROBOLO or Dry Flush units, which prioritize ease of use. Ultimately, the right choice depends on your specific needs—whether that’s off-grid living, frequent travel, or simplicity in maintenance.
