Rota Loo 950

The Rota-Loo 950 is a unique batch composting solution for larger households or high-usage areas, accommodating up to 8 full-time users. This model is capable of connecting two toilet pedestals to a single composting unit, making it the preferred choice for families seeking an effective and sustainable waste management system.

The larger Rota-Loo 950 requires 38 inches of clear space below the toilet floor level. If you lack sufficient space, you might consider the smaller Rota-Loo 650 or for example the GL 90 split-system composting toilets, which are similar to the Rota-Loo 950 but require significantly less room below floor level. For situations where there is no space available beneath the floor, our self-contained waterless toilets may be a suitable option.

Key Features

  • Rotating Design: The Rota-Loo composting toilet features a large composting container divided into multiple inner composting bins/compartments. A single bin is connected to a porcelain dry toilet pedestal at any one time. When a bin fills up, the internal structure is rotated clockwise to bring a new empty bin into use, while the full bin remains inside to continue composting. This results in batches of compost being processed simultaneously within the unit.
  • Enhanced Capacity: Designed to serve a large family, the 950 model can efficiently cater to the needs of up to 8 individuals, ensuring reliable performance even under high demand.
  • Dual Pedestal Compatibility: Unlike the smaller 650 model, the 950 can accommodate two toilet pedestals simultaneously, offering greater flexibility and convenience for domestic installations.

Operating on a batch composting principle, the Rota-Loo 950 facilitates an odorless, chemical-free process that converts human waste into nutrient-rich humus. This method aligns with eco-friendly practices by minimizing water usage and avoiding the environmental impact associated with traditional sanitation systems.

What is a batch composting toilet?

A batch composting toilet is a waterless toilet that processes human waste through composting in separate batches. Unlike continuous composting systems, which handle waste in a single, ongoing process, batch systems compartmentalize the composting activity into distinct containers or bins. Each bin is filled sequentially, then set aside to allow the waste to compost over time, typically several months, transforming it into nutrient-rich mulch. Once a bin is full, it’s sealed and a new bin is used, minimizing handling and ensuring an odorless, chemical-free process. This method effectively reduces waste volume and recycles nutrients. Batch composting toilets are generally praised for their hands-off approach to the maintenance of waterless toilets.

Rota-Loos are exemplary models of a batch composting toilet. This innovative design incorporates multiple bins within a single large container, each acting as a separate batch unit. As one bin is connected to a dry toilet pedestal and fills up with human waste, it follows the fundamental principles of batch composting by isolating the waste. Once the bin reaches capacity, the internal mechanism of the Rota-Loo allows for the rotation of the container, positioning a new empty bin under the waste chute.

The full bin, now disconnected from the toilet, remains within the unit, where the composting process continues undisturbed. Over several months, the waste in this bin breaks down into nutrient-rich mulch. This system minimizes manual handling of raw toilet waste and maintains an efficient, odorless operation throughout its cycle.

How Rota Loo works?

The Rota-Loo functions much like a rotating clock. Picture it with multiple bins, starting with Bin 1 positioned at what would be 12 o’clock. This bin is used initially and typically fills up over the course of two to three months. Once Bin 1 is full, you simply rotate the Rota-Loo system clockwise to bring the next bin into the primary position at 12 o’clock for use.

This rotation process is repeated as each bin fills. By the time Bin 1 comes full circle back to the 12 o’clock position, usually about a year later, its contents have transformed into a rich, nutrient-dense humus. This humus is not only safe but also beneficial for your garden, completing the eco-friendly cycle. The emptied bin is then ready to be put back into use, starting the process anew.

Installation

The Rota-Loo is designed to be installed with ease and is ideal for both residential and commercial settings. It is supplied as a comprehensive kit, which can be assembled using standard tools that are readily available at most hardware stores.

Space Requirement

The Rota Loo 950 is a split-system composting toilet, meaning it requires a free clearance below the toilet floor level. Specifically, this model needs a minimum of 38 inches of space beneath the floor to function properly. Split-system composting toilets, by design, always necessitate some clearance below floor level.

If you don’t have enough space, you might want to look into the smaller Rota-Loo 650 or the GL 90 split-system composting toilets, which are comparable to the Rota-Loo 950 but need much less space below the floor level. In cases where there is no space below the floor, our self-contained waterless toilets could be an ideal solution.

Installation Highlights:

  • Site Preparation: A flat, level base should be ensured, shielded from the elements, with adequate space allocated for the unit and ventilation components, and convenient access for maintenance.
  • Assembly: The toilet pedestal is to be positioned directly above the Rota-Loo unit to ensure a vertical drop.
  • Ventilation Setup: A ventilation system must be installed to control odors and facilitate the composting process. This involves the fitting of ventilation pipes and a fan to ensure effective air flow.
  • Service Access: Regular access to the compost bins should be planned, making them readily accessible for easy servicing approximately every two months.
  • Power Requirements: The electrical setup for the fan should be prepared.

Before its use, final checks should be conducted to confirm that everything is installed correctly and functioning as expected. This straightforward setup process, coupled with routine maintenance, ensures that the Rota-Loo will be pleasant to use and service.

Service

Servicing the Rota-Loo is designed to be straightforward, ensuring continuous and efficient operation. Here’s a simple guide to servicing the system:

  • Bin Rotation: When a bin becomes full (remaining no more than 4 inches below the top), it is rotated. The access door should be opened, and a mixture of compost starter and water, as specified by the compost starter instructions, should be added through the pedestal.
  • Compost Covering: It is recommended that the compost be covered with about 1 inch of covering material to enhance decomposition.
  • Advance the Bins: The bins are rotated one position clockwise. The bin now under the waste chute, filled with composted material unless it is the first use, should be emptied.
  • Empty and Prepare: The composted material is to be emptied safely. The jute liner, which decomposes more slowly, can also be composted. A new jute liner should be placed in the emptied bin, covered with 2 inches of covering material, and the bin returned to the Rota-Loo. The door is then closed, preparing it for reuse.
  • Record Keeping: The Bin Rotation Diary is to be used to record when bins are turned and emptied. This diary should be kept either on the door of the Rota-Loo or in a nearby accessible location.

These steps ensure that the Rota-Loo is maintained properly, supporting the natural composting process, minimizing maintenance efforts and keeping the toilet pleasant to use.

    This is not our first composting toilet, but the first we’ve had with the below-deck composting compartment (ie. large scale). Although we imported directly from Australia some time ago, we’ve only just installed and started using the product for a few months. We’re very happy with the product’s simplicity and elegant (and more importantly easy-to-clean) porcelain pedestal. The only constructive criticism we have at this time was the lack of installation instructions for the system as a whole. While there was plenty of documentation on the composting bins themselves, instructions on how to fix the assembly to the building or even attaching the toilet seat lid (which seems to be backwards from North Americal standards) was lacking in both the physical manual that came with delivery and the electronic manual that was sent to us ahead of time while we awaited shipment. That said, when we did reach out for support were were provided with exactly the information we needed, including diagram, in less than an hour – FANTASTIC customer service!

    Grateful to hear shipment is now available from North America (it was VERY expensive to import, although more cost effective than septic or holding tank which also requires costly maintenance). In 8-12 months, once we’ve been through an entire cycle of bins, if all goes well we plan on purchasing this item again for another off-grid project.

I recently installed a family 120. Works well so far. I was planning a split system that I didn't think was manufactured and found this shop and it fit perfectly! Hallelujah! Saved me a bunch of time. I added an extra air tube in the corners from a section of drain pipe with the holes to help keep the compost aerobic.

CF 8 Composting Toilet – Estimated Daily Capacity

The CF 8 is a continuous composting toilet system featuring a single large 250-gallon container. Like the CF 4, it is designed for gradual emptying rather than batch-style use. Solids are typically removed in thirds or sections, allowing earlier deposits time to fully compost inside the tank.

This setup allows for either:


🔁 Continuous Use: Gradual Emptying in Thirds

When used year-round, the CF 8 is typically emptied one-third at a time, effectively composting in three rotating “piles” within the container.

Because the CF 8 is more than twice as large as the CF 4, each pile can hold approximately 480–960 poops, depending on composting conditions and how much bulking material is used.

Service Interval (per pile) Estimated #2 Visits per Day
30 days (1 month) ~17–32 visits/day
60 days (2 months) ~8–16 visits/day
90 days (3 months) ~5–11 visits/day
180 days (6 months) ~3–5 visits/day
365 days (1 year) ~1.2–2.6 visits/day

💡 These figures assume that one-third of the tank is in active use at a time, with older waste given time to compost before removal.


🌤 Seasonal Use: Full-Tank Emptying After Inactive Period

For cabins, cottages, or other sites used seasonally, the CF 8 can be used for a few months and then left idle to allow full composting. In such cases, the entire tank may be emptied once a year.

Full-tank capacity estimate: ~1,440–2,880 poops

Example: 120 days of use (approx. 4 months):
→ ~12–24 solid visits per day on average


⚠️ Disclaimer

These numbers are rough estimates based on typical use and conditions. Actual capacity will vary depending on:

For best performance, ensure proper aeration, regular bulking material use, and consistent emptying of composted portions.


💡 Want to Maximize Capacity? Consider a Urine-Diverting Toilet — With Some Important Considerations

upgrade to a urine diverting toilet pedestal

If you’re looking to maximize the capacity of the CF 8 system — aiming for 960+ poops per composting “pile” — we recommend using a urine-diverting (UD) toilet pedestal.

✅ Benefits of Urine Separation:

By diverting urine out of the solids container, the volume taken up by absorbent material (like peat or wood shavings) is significantly reduced. This can make a big difference in how often the system needs to be emptied.


⚠️ Downsides to Consider:

Urine-diverting toilets can take some time to get used to. Users need to sit or aim correctly to ensure proper separation, which might not happen consistently without experience or guidance.

For this reason, UD toilets are generally not ideal for public or commercial settings where the toilet is used by guests, tourists, or other first-time users. In these cases, misuse can reduce the effectiveness of the system and may even lead to unpleasant maintenance issues.


In short: A UD toilet is an excellent choice for maximizing capacity in private or family use, but for guest or public access composting toilets, a standard non-diverting model may be more practical and user-friendly.

Green Toilet 100 Easy – Estimated Daily Capacity

The Green Toilet 100 Easy is a compact and user-friendly batch composting toilet with a 26-gallon composting container. Its design makes it well-suited for outhouses, cabins, and even indoor use. A spare container is available to expand capacity and simplify servicing.


🔢 Estimated Solid-Waste Capacity per Bin:

Note: Due to the shape and internal structure of the container, the actual composting capacity is slightly lower than its raw volume might suggest, if you compare with Green Toilet 120 Family composting toilet for example.


📆 Average Daily Capacity per Bin

Service Interval Estimated #2 Visits per Day
30 days (1 month) ~6–7 visits/day
60 days (2 months) ~3–4 visits/day

CF 4 Composting Toilet – Estimated Daily Capacity

The CF 4 is a continuous composting toilet system featuring a single large 105-gallon container.

This setup allows for either:


🔁 Continuous Use: Gradual Emptying in Thirds

When used year-round, the CF 4 is typically emptied one-third at a time, effectively composting in three rotating “piles” within the container. Depending on composting conditions and how much bulking material is used, each pile can hold approximately 200–400 poops.

Service Interval (per pile) Estimated #2 Visits per Day
30 days (1 month) ~7–13 visits/day
60 days (2 months) ~3–7 visits/day
90 days (3 months) ~2–4 visits/day

Service Interval #2 Visits per Day (involving pooping)
30 days (1 month) ~33 visits/day
60 days (2 months) ~17 visits/day
90 days (3 months) ~11 visits/day
180 days (6 months) ~5.6 visits/day
365 days (1 year) ~2.7 visits/day

🟢 What counts as a “#2 visit”?
Only visits that involve defecation (pooping) — urine-only visits don’t fill up the composting bin and are not included in the 1,000-use estimate.

⚠️ Disclaimer:
These estimates are based on typical, steady use. The actual number of solid uses a composting bin can handle may vary significantly depending on climate, temperature, humidity, ventilation, and how much dry bulking material (like wood shavings) is added after each use.
