7 best composting toilets for homes
Composting toilets for homes are innovative and sustainable sanitation solutions that can be used in residential settings to efficiently manage human waste while reducing the environmental impact. Here's what you need to know about composting toilets:
How Composting Toilets Work:
- Composting toilets use a natural biological process called composting to break down human waste into a safe and odorless soil conditioner.
- They separate solid waste from liquid waste, allowing for better composting conditions.
Components:
- Composting toilets typically consist of a toilet bowl or seat, a waste collection chamber, a ventilation system, and a composting chamber.
- The ventilation system promotes aerobic decomposition and prevents odors by continuously moving air through the waste material.
Types of Composting Toilets:
- Self-contained Units: These are all-in-one units where both the composting and collection chambers are in the same fixture. They are suitable for smaller spaces.
- Remote Systems: In remote systems, the composting chamber is located separately from the toilet fixture. This design allows for more flexibility in installation.
Advantages:
- Environmentally Friendly: Composting toilets reduce water consumption since they don't require flushing, helping conserve water resources.
- Low Impact: They can be a sustainable option for homes in areas with limited access to sewage systems.
- Nutrient-Rich Compost: The end product, called "humanure," is a valuable soil conditioner rich in nutrients that can be used for gardening.
- Off-Grid Living: Composting toilets are ideal for off-grid or remote homes where traditional sewage systems are not feasible.
Maintenance:
- Regular maintenance is required to ensure proper operation. This includes monitoring the composting process, adding bulking agents (like sawdust), and emptying the compost chamber when it's full.
- Ventilation fans and the composting process itself help control odors, but occasional cleaning and maintenance are necessary.
Regulations and Permits:
- Before installing a composting toilet, check local regulations and obtain any necessary permits. Regulations can vary by location.
Cost:
- The initial cost of a composting toilet can be higher than a conventional flush toilet. However, long-term savings on water bills and potential environmental benefits may offset the upfront investment.
Installation:
- Composting toilets can be installed indoors or outdoors, depending on the model and local regulations.
- Proper ventilation and access to electricity may be required for the unit to function effectively.
In summary, composting toilets are eco-friendly sanitation solutions for homes that can reduce water consumption and provide valuable compost for gardening. They come in different types and require regular maintenance for optimal performance. Ensure compliance with local regulations and consider the long-term benefits when deciding whether to install one in your home.

| Question: | Other composting toilets of similar size have some kind of mixing system to mix composting medium with solid waste. How is the solid waste handled |

| Question: | How many uses before the solids must be removed |
| Answer: | I don't have this exact one but the plunger on the left top should be your flush. You should have a holding tank for clean water that will need to be filled to flush properly. The top comes of and the waste is in the bottom half that will need to be dumped and rinsed, can be flushed down a toliet. No batteries should be needed. |

User questions & answers
| Question: | Can these portable toilets be connected to the sewer pipe (black water hose) at campgrounds |
| Answer: | No. The bottom portion that stores the waste water has to be deprecated and dumped. |
| Question: | How much water is released when pump os operated |
| Answer: | If I were to guess I'd say 1-2 cups, roughly 240-475 ml |
| Question: | Is the center hole 8 x 9 like most others |
| Answer: | You're correct. It's 9 in. front to back and 8 1/4 in. wide. You made me curious, so I measured my bathroom toilet. It's considered a long bowl and measures 10 in. front to back and the same 8 1/4 in. wide. Thank you for helping me learn something new. If I'm ever confronted by a mugger who says "tell me how big your toilet is or I'll blow your head off" I now know the answer. You may have saved my life! |
| Question: | What happens after 50 flushes? Is there a battery and is it replaceable? Not enthusiastic about purchasing a new one every 50 flushes |
| Answer: | There are two halves, top half has a cap to fill clean water and a plunger to push the clean water into the tank. The bottom half is for the waste which needs to be empty. There is an indicator in the front to let you know when it's due. I empty it about 3/4 full. I made the mistake once when the level was all red, DON'T DO THAT! 3/4 is best. To break down the waste, I use Walex Bio-Pak (for breaking down waste) and Porta-Pak (deodorizer), one each. I put them after setting it up and after each cleaning. It almost completely turns it into liquid. Fresh scent porta-pak seems to smell better (blue package) than lavender (purple package), however bio-back (green package) IS DEFINITELY NEEDED to break down waste. After the bottom tank gets full, (more like 40 flushes than fifty) it needs to be emptied, rinsed out with clean water and set back up. After its set up put in one bio-pak and one porta-pak. You can order through Amazon for those. The water tank, upper portion holds about 2.5 gallons (about 9.5 liters), I don't pull the plunger all the way up, only about half way or as needed. This way it conserves on water. Hope this helps. |

User questions & answers
| Question: | how do you vent it |
| Answer: | you must vent it through to the outside. Instructions specifically state not to use vent replacement valves,maybe due to oders. |
| Question: | Will this support a bathroom and laundry |
| Answer: | The SaniBEST Pro would be the best choice for your situation. Itâs the most popular and economic system for adding a full bath with laundry. The SaniBEST can be used it with any sink and any shower (just standard PVC connections coming into the pump). You will just need to elevate the shower by 6 inches to fit the P-trap and for the gravity fall to the pump. The washer can be connected via an indirect connection such as a laundry sink. |
| Question: | Would this toilet be capable of handling drain water from a shower or bathtub |
| Answer: | I have it connected to my shower, I don't think its capable of handing the amount of water from a tub. You would need to get a separate saniflow like they have for the washers. You can call to check though. |
| Question: | larry reed, why did you connect a shower to it. was it so the macerator pump would pump out the shower water? i am considering the same thing |
| Answer: | There was no other outlet for the shower. My septic is four ft above the basement floor. Works good, hope this helps. |
| Question: | is this unit A D A compliant |
| Answer: | No |
| Question: | was told you have to raise the toilet if you use ex. pipe is this true |
| Answer: | Nope, false |
| Question: | Can I have the toilet on one side of wall and the macerator on the other side of the wall. Also will it connect to a shower and sink |
| Answer: | The Saniflo "access 3" will accept a shower/tub and a vanity as well as the toilet itself. And you would need to purchase an extension pipe fro Saniflo to put the pump behind a wall. |
| Question: | For how long is the warranty |
| Answer: | Saniflo offers a 2-year warranty for the pumps and a 1-year warranty for the toilet bowl and tank. The warranty starts from the date of purchase. If you register the pump online at Saniflo, you can get an extended warranty of 1 year for free. |
| Question: | How high above the floor is the inlet hole for a drain pipe from a sink |
| Answer: | Not sure exactly, but as I recall it was about 5, 6” above but somewhat flexible |
| Question: | I have an existing gravity feed toilet. Can I replace/connect this on top of the standard floor sewer line my existing toilet is currently seated on |
| Answer: | Yes & no. Yes, you can install on top of existing toilet drain, but no, to do so you would have to cap existing toilet drain (to prevent sewer gas from escaping) and tie sanicompact 1" discharge line into toilet vent line in wall. But why? |
| Question: | We lost 1 anchor bolt. Mfr wont sell 1. Can you suggest acceptable bolt from hardware store |
| Answer: | Take the one bolt you have to the hardware store, find a close match, buy two and throw away the original. |
| Question: | I do not have a sewage pipe I can attach the pipe to,can I use a standard drain used for a washing machine and general cleaning |
| Answer: | Thanks so much for contacting us. Yes, you can connect it into the same drainage line as long as that washer drain pipe drains into the main city sewer or septic tank (so it is standard black water waste). The only concern is if any other pipes are tied into that same drain pipe that may obstruct the air flow or may suck out the p-trap dry, then odor will come out that p-trap. If you have any other questions, please feel free to give us a call. We're happy to help! Sincerely - Support Team @ upflushTOILET.com (855) 70-FLUSH (855-703-5874) |

User questions & answers
| Question: | what unit would i need to buy for a shower, toilet and sink |
| Answer: | For a full bathroom you'll want the SaniACCESS 3. The ACCESS 2 only handles 2 fixtures (sink and toilet), whereas the 3 handles three fixtures (sink, toilet, shower/bath). |
| Question: | How far will it pump |
| Answer: | I have it set up for 25' distance with about 4' head to septic tank. No problems so far. Adding another shortly. |
| Question: | Can anyone please tell me the ballpark figure it might cost to have this toilet installed |
| Answer: | I just installed one last week. Although the unit itself is basic plumbing, the path of the drain lines can be difficult in some situations. If the plumbing in your house is accessible, it is not too bad. If you call a plumber, it could be as little as $200. However, it could also be several hundred,depending on access to main stack. |
| Question: | washing machine in my detached garage drains into a 2 inch drain pipe that connects under our home. What's minimum that I need to buy |
| Answer: | This unit drains with a 3/4”or 1” line there’s no problem |
