Phoenix™ R-199 is the compact, low-profile Phoenix™ Composting Toilet engineered for places where space is tight but reliability can’t be compromised—cabins, tiny homes, bunk rooms, back-country huts, staff quarters, and sleepouts. Built with a thick cross-linked polyethylene chamber and stainless hardware, the R-199 delivers the same Phoenix™ biology and odour control as larger models in a smaller footprint that fits low crawl spaces and tight plant rooms.
Capacity
Residential rating: 2 persons, continuous use (assume ~6 uses/person/day).
Peaks & day-visitors: day-visitor (single-use) guidance available; short surges are typically tolerated at ~30% above day-visitor daily average.
Important: when using multiples, plan clear service access to each unit for mixing and annual removal.
Scalable: deploy multiple (e.g., 2–3 R-199 units) to serve whole-home layouts or extra bathrooms. This approach preserves the R-199’s low height advantage while increasing overall capacity.
Features
Odourless operation: a continuous 12 V fan maintains negative pressure through the chute and vent stack—fresh bathrooms even at higher loads.
Mixing: heavy stainless rake/mixing tines geometry—built for commercial reality.
Built to last: cross-linked polyethylene chamber and stainless hardware withstand commercial environments and seasonal extremes.
Flexible interfaces: dry toilet via 310mmDia vertical chute, or micro-flush/vacuum-flush where falls or distances demand it—interfaces to suit architecture, fall constraints, and user expectations.
Serviceable design: annual compost removal via the lower access door; straightforward checks for fan, vent, drains, and spray system.
Low energy demand: ~5 W continuous—simple to run from solar/battery systems.
Bathroom Fixture options
- Waterless dry toilet via 12" (~310 mm) vertical chute for the simplest, lowest-maintenance install. (ZERO DISCHARGE SYSTEM)
- Micro-flush (≈0.5 L) or vacuum-flush options where architectural layouts need offsets or same-floor runs.
Applications
Small eco-cabins, baches, and tiny homes where space is tight and water is limited.
Remote homesteads and lifestyle blocks wanting a simple, low-maintenance residential system.
Glamping pods, guest cottages, and seasonal accommodation with light-to-moderate use.
