Nomad Urine Separation Toilet

The Nomad by OGO is a portable urine separation toilet designed for off-grid and outdoor use. Its waste separation mechanism minimizes odors by isolating urine from solids, creating a more sanitary and less smelly experience in cabins, boats, or camping setups. With no water flush required, Nomad is ideal for boondocking where fresh water is scarce or where a compact, low-maintenance system is preferred. Constructed from durable high-density polypropylene, Nomad balances light weight with rugged durability for frequent travel and remote deployments.
- Portable design for camping, boating, RVs
- Urine and solid separation reduces odor
- Durable high-density polypropylene construction
Nomad’s waterless approach and odor-control strategy make it a strong choice for off-grid adventures and temporary or seasonal cabin setups where traditional plumbing isn’t available.
Laveo Dry Flush Toilet

The Laveo Dry Flush Toilet is a waterless, self-contained system designed to be easy to use in tiny homes, vans, boats, RVs, and off-grid cabins. Each package includes a battery and charger, cables, two waste cartridges, and a bottle of Pee Powder that extends cartridge life by up to 40 percent. The system is designed to be simple and odor-free: no bulking materials or chemicals are required, and when a cartridge fills, the waste bag is sealed and removed. The Dry Flush approach is especially appealing where plumbing is impractical or absent and where user-friendly disposal is important.
- Battery and charger included; no external power required
- Two cartridges plus Pee Powder for longer cartridge life
- 100% odorless with airtight waste bags
- No bulking material; simple cartridge-based disposal
For off-grid cabins needing a compact, self-contained unit with straightforward upkeep, Laveo’s dry flush design reduces maintenance while keeping odors contained.
Ignalu Compact Urine Diverter

The Ignalu Urine Diverter is a compact accessory designed to fit luggable Loo setups, snap-on seats, RVs, boats, and cabins. It provides odor-reducing separation by isolating liquids from solids, which helps minimize smells in enclosed spaces. The unit offers dual drainage flexibility, allowing urine to be diverted into an internal container or discharged externally via a tube (tube sold separately). The ultra-compact design prioritizes space efficiency, making it an attractive upgrade for small bathrooms or tight off-grid interiors where space is at a premium.
- Odor-reducing urine/solid separation
- Dual drainage options for flexible disposal
- Ultra-compact and space-saving
Ignalu’s diverter is best suited for users who rely on bucket-style or simple composting arrangements and want improved odor control without major plumbing changes.
CrestWave 500W Macerator Pump

The CrestWave 500W Macerator Pump is a heavy-duty upflush system designed to move waste from sinks, toilets, showers, and other fixtures where gravity drainage isn’t feasible. It features an industrial-grade copper motor that runs quietly at about 45dB, making it less intrusive in living spaces. The unit’s stainless steel blades pulverize solids into slurry to prevent clogs, and its IPX4-rated casing guards against water leaks. With multiple inlet options (up to four), this pump enables flexible drainage for basements, attics, boats, or RVs where conventional plumbing isn’t possible and remote drainage is required.
- Ultra-quiet operation at 45dB
- Four inlet connections; upflush versatility
- 500W motor; copper winding for durability
- IPX4 waterproof casing; reliable in damp environments
For off-grid installations where wastewater must be moved to a remote or elevated outlet, CrestWave provides a robust, noise-conscious solution capable of supporting multiple fixtures from a single pump.
Buying Guide
Key Purchase Considerations
- System type and water use: Decide between waterless dry-flush, urine-separation, or macerator-based setups based on water access, waste handling preferences, and space constraints.
- Odor control: Look for sealed waste bags, coagulants, or cartridge-based systems to minimize smells in compact living areas.
- Maintenance and consumables: Assess how often cartridges, bags, Pee Powder, or replacement parts are needed and how easy they are to obtain.
- Power and portability: If you are relying on solar or battery power, confirm battery life, charging options, and power requirements of the unit.
- Durability and weight rating: Consider materials, build quality, and weight limits if the unit will be used by multiple occupants or during travel.
- Ease of installation and operation: Choose systems that fit your space and require minimal specialized plumbing or tools.
- Waste disposal practicality: Ensure the disposal method aligns with local regulations and your preferred waste management plan.

To match your cabin’s layout and lifestyle, weigh these scenarios: If you need a lightweight, maintenance-light option with strong odor control for a tiny or remote cabin, a dry-flush or urine-separation system is typically ideal. If you already have or plan to install a basic sink or shower and require moving wastewater to a distant outlet, a macerator pump can unlock new layout possibilities. For boats or RVs with limited space, compact, self-contained models reduce plumbing complexity while keeping odors in check. Each approach has trade-offs in consumables, power needs, and disposal logistics, so align your choice with how you live and travel off-grid.
