How It Works, Capacity & Maintenance

  • Not all of them, it depends on the brand. The Cinderella Incinerating Toilet is specifically engineered to be odourless, using a catalytic converter, a fan, and a dedicated venting system to fully process combustion byproducts. When installed and maintained properly, a Cinderella won’t smell like burning waste, inside the bathroom or outside near the vent.

  • A Cinderella Incinerating Toilet burns waste at very high temperatures inside a sealed incineration chamber, using a liner for each use. The resulting steam and vapours pass through a catalytic converter and exit through a dedicated vent pipe, separate from the bathroom. What’s left after each cycle is a small amount of sterile ash (about a teacup’s worth for four people over a week of use) with nothing to store, compost, or transport off-site.

  • A Cinderella Incinerating Toilet can handle 3 to 4 visits per hour. Preheating the unit before hosting a full cottage of guests will slightly increase the capacity.

  • Yes. The liner is designed specifically for Cinderella models and is required for proper operation and to keep the toilet clean.

  • No. A Cinderella Incinerating Toilet is a self-contained, waterless system that requires no water supply, drainage plumbing, or digging. It converts waste directly into a small amount of ash rather than routing it through pipes.

  • Yes. Opening the lid automatically pauses the incineration cycle. It resumes once the lid is closed and the ‘Start’ button is pressed again.

  • Yes, regular maintenance is required, since the system operates at very high temperatures. It needs two types: regular maintenance (emptying the ash container about once a week, or every 100 uses) and seasonal maintenance (flushing the filter every 500 uses). Full instructions and 3D animations are in the owner’s manual and on our website.

  • Each Cinderella model tells you automatically, though the exact signal varies. The Comfort and Freedom display an “Empty Ash Container” message on the LCD screen with a beeping alert at 90 uses. At 120 uses, the same alert appears but the toilet won’t let you start another cycle until the ash container has been physically removed and reinserted. The Premium works the same way, plus its display shows a running flush counter so you can see exactly how many uses have accumulated since the container was last emptied. The Travel model doesn’t have an LCD display, so it uses beeping along with a sequence of flashing LED lights to signal different messages, like when to empty the ash container.

  • A composting toilet breaks waste down slowly through decomposition, which usually means separating liquid and solid waste and keeping up with regular maintenance. A Cinderella Incinerating Toilet handles both together in one step, burning waste into a small amount of sterile ash, which is why it tends to be the lower-maintenance, odour-free, year-round option. Composting can be the more budget-friendly choice for someone willing to do the extra upkeep; incineration is the better fit for anyone prioritizing simplicity and four-season reliability. See our incinerating-versus-composting toilet guide for a fuller comparison.

  • Typically every 4 to 6 years under normal use, though this varies with usage volume and environment. Full-time, year-round use may require service sooner, similar to how tires wear faster with heavier use. Four or five internal components (depending on the model) are expected to wear over time and our local Cinderella dealers or other qualified trades can replace those parts.

  • Preheat the unit before guests arrive: lift the lid, close it, and press the incineration button to run a dry cycle. This brings the toilet up to operating temperature ahead of time so it can keep pace with multiple guests within the same hour.

  • Cinderella toilets are rated at 54 dB, measured one metre above the unit, which is about as loud as a running dishwasher.

Waste & Ash

  • A Cinderella Incinerating Toilet is designed to incinerate urine, human feces, toilet paper, tampons, and sanitary pads only. Other materials shouldn’t be placed in the unit.

  • Properly incinerated waste leaves behind light grey, powder ash made mostly of salts and minerals. These crystals often stick to the ash pan and can be hard to remove dry, but dissolve easily after 15–30 minutes soaking in hot water.

  • Yes. The ash is sterile and contains potassium and phosphorus, making it suitable for fertilizing soil.

  • The ash from a Cinderella Incinerating Toilet is completely sterile, so it can be disposed of in regular household waste or used as fertilizer in your garden.

Power: Propane, Electric & Solar

  • A standard 20 lb (9.1 kg) propane tank (the same size used for a household barbecue) typically powers 75 to 100 incineration cycles on a Cinderella Freedom propane model. Cinderella’s North American manual specifies fuel consumption of 0.449 lb (0.204 kg) per burner-hour, rather than a fixed number of cycles per tank; actual results vary with use.

  • Not directly. There’s no dedicated low-propane indicator, but when the tank runs empty, the yellow light flashes and the display reads “Error Burner System.” The unit will drop the waste into the combustion chamber, but will not incinerate. It will attempt to light three times before displaying the error message.

  • Cinderella’s electric models use between 0.8 and 2 kWh per incineration cycle, averaging around 1 kWh per cycle in our in-house testing.

  • The recommended minimum is a 100-watt solar panel paired with a 125 amp-hour AGM battery, or a portable power station like the EcoFlow River 2 Max sold on our website, though exact needs vary by usage pattern and location. We recommend consulting a professional to size a system for your specific off-grid property.

  • It depends on the model. The Cinderella Comfort (electric) includes a small backup battery in every unit so if power cuts out, the heating element stops immediately, but the battery keeps the fan running so it can finish exhausting and cooling down the chamber. The Cinderella Freedom (propane) can run on standard house power or directly off a generator, 12V marine battery or solar setup; if it’s plugged into wall power and the power goes out, it’s simple to disconnect the adapter and connect a battery instead to keep using the toilet without interruption. For fully off-grid installations already running on solar or battery power, a grid outage isn’t a factor at all. If the power will be out for an extended period the ash container should be emptied. Un-incinerated waste left in the chamber is corrosive and can damage internal components over time.

  • Wait until both the incineration cycle and the cool-down process are complete (the yellow light will turn off) before unplugging.

Installation & Venting

  • A Cinderella Incinerating Toilet can be installed in a home, cottage (including cottages with no winter water), garage, boathouse, bunkie, basement, outhouse, portable washroom, pool house, hunting camp, fish hut, tiny house, off-grid cabin, RV/trailer, mining-industry site, houseboat, emergency service vehicles, and anywhere else you need a waterless toilet!

  • This depends on your local building department, since requirements can vary by municipality even within the same province. Thousands of Cinderella Incinerating Toilets have been sold and installed across Canada, and some municipalities have started recommending incinerating toilets to homeowners facing failed septic reinspections. Because rules vary by location, we recommend contacting your local building department before installation to confirm what applies to your property.

  • It depends on your property and local regulations. A Cinderella Incinerating Toilet eliminates blackwater entirely, so in some locations that removes the need for a septic system altogether. However, you’ll still need a way to handle greywater from sinks and showers, and requirements vary by municipality. We recommend checking with your local municipality or environmental governing body to confirm what applies to your specific property before making any final decisions. Read more about septic alternatives for Canadian cottages.

  • No. The Comfort (electric) and Freedom (propane) models each have a maximum number of vent pipe bends specified in their installation manuals. Extra elbows restrict airflow, reducing incineration quality and risking system breakdown over time.

  • No. Fresh air must come from outside the building, which is supplied directly to the Comfort model, or indirectly through a fresh-air intake positioned close to the toilet on Freedom installations. This intake can be on an exterior wall or through the floor for both the Comfort and Freedom models.

  • Yes. The Cinderella Travel RV model is designed and certified for Canadian use in RVs, campers, and vans, eliminating the need for a black water tank.

Climate & Winter Performance

  • It can. The enclosed ventilation system may condense when outdoor temperatures are much colder than the room’s indoor air, so it includes a small drain to handle moisture. Proper room ventilation matters most in spaces that also have a shower or bath. Note: a bathroom exhaust fan will conflict with the Freedom (propane) model but not the Comfort model, since Comfort is a two-pipe system unaffected by exhaust fans. For cold-climate properties, we recommend the Comfort model with the winter kit.

  • Yes. Designed and manufactured in Norway for cold climates, Cinderella says its cabin models are tested and approved down to −20°C ambient bathroom temperature. If a Comfort (electric) model will be used through winter in a heated space, we recommend installing the winter kit; it isn’t required for unheated spaces.

Certifications & Choosing a Model

  • Pricing varies by model. See the Comfort, Freedom, Premium, and Travel product pages for current toilet prices. Each toilet requires a compatible ventilation kit, priced separately. The Unisex Urinal is sold separately. For all current prices, visit our shop. It is worth comparing those costs with a full septic system replacement, which in Ontario commonly runs $20,000–$50,000+ and may not be an option on rock or shoreline lots.

  • Yes. Cinderella Incinerating Toilets are certified to both Canadian and U.S. standards. The full certification list is on Cinderella Eco Group’s certifications and approvals page.

  • Yes. A Cinderella Incinerating Toilet is NSF and C-UL-US certified, and designed so the combustion chamber cannot be opened once an incineration cycle has started, and independent lab testing rated the risk of a child accessing the ash pan or coming into contact with hot or moving parts as very low to low. The exterior does get warm during a cycle but stays well below a burn-risk temperature. As with any household appliance involving heat, we still recommend normal adult supervision for young children.

  • Cinderella’s reputation rests on four things: quality, safety, capacity, and efficiency. That track record includes decades serving customers plus independent lab testing and comparison chart, including testing by Canada’s New Brunswick Research and Productivity Council, which found Cinderella toilets among the easiest to use and most consistent in build quality and performance, with the Comfort and Freedom models both completing heavy-use testing successfully.

  • For most cottage and off-grid properties, yes. In independent third-party lab testing and comparison chart, Cinderella was the only brand that completed heavy-use testing (simulating a full weekend of guests) without failing or leaving waste unburned. Incinolet and EcoJohn both fell short under the same conditions. Cinderella also comes with a longer warranty (3 years vs. 1–2 years for competitors), runs quieter, and includes a catalytic converter standard. The lower upfront price of some competitors doesn’t always reflect what you’re actually getting once daily use and reliability are factored in.

  • Premium shares the same core technology and capacity as Comfort but adds a sleeker design and several convenience upgrades: a soft-close lid, a Teflon-coated bowl so liners slide smoothly into the incineration chamber, and an advanced digital menu with an incineration-cycle counter/timer, a steam-cleaning filter program, and a front hatch that locks and opens only from the display menu. See our Cinderella model guide for a broader comparison.
