Nature’s Head Self Contained Composting Toilet

After using the Nature’s Head Self Contained Composting Toilet for a few months in my RV, I can say it’s been a game-changer for off-grid living. At first, the idea of spending nearly $1,000 on a toilet seemed a bit extravagant, but the convenience and eco-friendliness it brings to RV life quickly made it worth every penny.

Installation was pretty straightforward—I’m no DIY expert, but I had no trouble following the instructions. It’s lightweight, only about 28 pounds, and made of robust plastic, which makes handling and setting it up easier than I expected. Plus, the fact that it’s made in America with a focus on sustainability is a nice bonus.

One of the standout features for me is its odor management. Unlike traditional RV toilets where you’re constantly worried about smells from the black tank, the Nature’s Head separates liquids and solids, keeping odors to a minimum. As long as you use the right composting medium—like coconut coir or peat moss—and give the solids bin a couple of cranks with the handle after each use, you’re good to go. And if you’re wondering, the “earthy” smell from the compost is barely noticeable, especially if you keep the fan running.

The capacity is another major plus. For two people using it regularly, you only need to empty the solids bin once every month or so, and the liquids bottle about once a week. I usually empty the liquid tank at a dump station or public restroom, and as for the solids, you can either compost it properly or bag it and throw it away responsibly. This makes it super convenient, especially if you’re boondocking or just want to avoid the hassle of dealing with a traditional black tank.

However, I’ve found that cleaning the composting bin can be a bit of a chore, especially if things get stuck in the corners. The agitator handle works well for most of the bin, but you might need to manually clean those hard-to-reach spots. It’s not a deal-breaker, but definitely something to keep in mind if you’re considering this model.

Overall, I’m thrilled with the Nature’s Head composting toilet. It’s freed us from the constraints of traditional RV sanitation systems and allowed us to camp wherever we want without worrying about finding a dump station. If you’re serious about sustainable RV living, this toilet is definitely worth considering.

Air Head Classic Composting Toilet

When it comes to finding the best composting toilet for RVs, the Air Head Classic is a standout choice that I’ve personally found to be a game-changer in off-grid living. Transitioning to a composting toilet felt a bit daunting at first, but after installing the Air Head in my RV, I realized why it’s so highly recommended by the RV community.

Installation Experience: The setup process was straightforward, even for someone like me who’s not particularly handy. The Air Head comes with all the necessary components, including a solids tank with an agitator, a separate urine bottle, a fan for ventilation, and a clear set of instructions. I decided to vent the toilet through the roof, using the existing black tank vent. This eliminated any worry about odors escaping into the living space—a major relief since nobody wants their RV to smell like a compost heap! Plus, removing the old RV toilet and capping the waterline was a satisfying step towards water conservation.

Daily Use: Using the Air Head is surprisingly similar to a standard toilet, minus the flush. The liquids and solids are separated efficiently, which is crucial for reducing smells and maintaining hygiene. The urine bottle needs to be emptied every day or two, depending on usage, which took some getting used to. The sight glass on the urine tank is a bit hard to read, especially in dim lighting, but a small flashlight does the trick to check the level.

Emptying the solids tank is much less frequent—about every two to four weeks for a couple using it full-time. I found this process straightforward. The top part of the toilet detaches easily, allowing me to bag up the compost and dispose of it responsibly. It might not be the most glamorous task, but it’s certainly more pleasant than dealing with a black tank!

Pros and Cons: One of the things I love most about the Air Head is its compact design. Space is always at a premium in an RV, and this toilet’s sleek profile fits perfectly into our small bathroom. The actual toilet seat is a standard size, so it’s much more comfortable than the molded plastic seats you find on other composting toilets. And the fan system keeps odors in check, making it a truly odorless experience in our RV.

However, the daily chore of emptying the urine bottle can be a bit tiresome, especially during long travel days or in the middle of the night. And like any composting toilet, there is a learning curve to managing the compost medium and keeping the system in balance. But honestly, these are minor inconveniences compared to the benefits.

Final Thoughts: Switching to the Air Head Classic was one of the best decisions we made for our RV lifestyle. It’s not just about the convenience of avoiding black tank dumps; it’s about embracing a more sustainable way of living. We’ve been able to extend our boondocking trips without worrying about fresh water for flushing or finding a dump station. For anyone looking to maximize their off-grid experience, the Air Head is a worthy investment despite the upfront cost.

If you’re considering a composting toilet for your RV, the Air Head Classic should definitely be on your list. It’s user-friendly, reliable, and perfect for those who want to enjoy extended adventures without the hassle of traditional RV waste management.

Separett Villa Composting Toilet

After using the Separett Villa 9215 Composting Toilet, I must say it’s been a game-changer for RV life. This compact, waterless toilet is perfect for anyone looking to be more eco-friendly without sacrificing convenience, especially when you’re on the road. Here’s my take on it.

Ease of Use and Installation: One of the best features of the Separett Villa 9215 is its simplicity. The urine-diverting system is a smart design that keeps liquids and solids separate, which significantly reduces odors and makes it easier to manage the composting process. However, installation can be a bit challenging if you’re not handy with tools. You’ll need to cut a hole in the wall for the vent and properly connect the urine drain hose to a greywater system or storage tank. It took me a while to set up, but once it’s in place, it’s virtually maintenance-free.

Performance and Maintenance: The unit runs on either AC or DC power, making it versatile for off-grid living as well as more traditional RV setups. It has a small fan that uses minimal energy to keep the air circulating, preventing any unwanted smells. I found that I only needed to empty the solid waste bin every 2-3 weeks, and the included compostable bags make this process clean and straightforward. Just remember, everyone—yes, even the guys—needs to sit down to use this toilet properly. It’s a small adjustment for the overall benefit of not having to deal with odors.

Environmental Benefits: Using no water at all, the Separett Villa 9215 is incredibly sustainable. It’s ideal for those who want to minimize their environmental footprint while on the road. For me, the best part is that it eliminates the need for a black tank, freeing up space for more greywater storage, which is a huge plus when you’re boondocking or in remote areas.

Pros:

• Completely waterless and environmentally friendly.
• Reduces odors by separating urine and solids.
• Low energy usage with the option to run on AC or DC power.
• Simple and low-maintenance operation once installed.

Cons:

• Initial setup can be tricky and may require additional tools.
• Urine drain hose and vent pipe installation could be a challenge, especially for RVs with thicker walls.
• Not ideal for very small spaces due to its size.

Overall, the Separett Villa 9215 is an excellent choice if you’re looking for a reliable, eco-friendly composting toilet for your RV. The convenience and environmental benefits far outweigh the initial installation hurdles. It’s been a worthy investment for my off-grid adventures, and I’d highly recommend it to any fellow RVers looking to make a positive change.

Best Composting Toilets for RVs: Your Ultimate Buyer’s Guide

Finding the right composting toilet for your RV is a game-changer, especially if you love boondocking or just want to reduce your environmental footprint. I’ve been down the rabbit hole of choosing the perfect model, so let me share what I’ve learned. Here’s what you should look for when picking the best composting toilet for your RV.

Price: How Much Should You Spend?
Composting toilets come in a wide range of prices, from budget-friendly options to high-end models. Generally, you’re looking at spending anywhere from $500 to over $1,500. The price often reflects the build quality, features, and capacity. While it’s tempting to go for the cheapest option, remember that this is an investment in comfort and convenience. A pricier model might offer more in terms of durability, ease of use, and less frequent maintenance.

Storage Tank Capacity: How Much Can It Hold?
One of the first things I looked at was storage capacity. This determines how often you’ll need to empty the toilet, which is key if you’re planning long stays off-grid. Most RV composting toilets have separate tanks for liquid and solid waste. The larger the capacity, the less often you need to empty it, which is especially important if you’re traveling with a family or a group. Aim for a model that offers at least 5-6 gallons for the liquid tank and a decent-sized solids compartment. Some can handle up to 80 uses before needing attention.

Decomposing Rate: Speed Matters
The decomposing rate depends on the model and how well you maintain the system. Composting toilets use either ventilation fans, heating elements, or just good ol’ natural airflow to aid decomposition. The faster the waste decomposes, the less you have to worry about odors and frequent emptying. Look for a model that has a reputation for quick decomposition and consider if you’re okay with using additional agents like coconut coir or peat moss to speed things up.

Ease of Installation: DIY or Call a Pro?
Installing a composting toilet in an RV can range from straightforward to head-scratchingly complex. Some units are almost plug-and-play, while others might require some serious DIY skills, like cutting vent holes or hooking up a 12-volt fan. If you’re not handy, I’d suggest choosing a model with a reputation for easy installation or consulting a pro. Trust me, the last thing you want is to be halfway through installation and realize you’re missing a crucial part or tool.

Size & Weight: Can It Fit?
RVs are all about maximizing space, and composting toilets can be a bit bulkier than traditional RV toilets. Measure your bathroom space carefully, keeping in mind the height and width of the unit, and don’t forget about any extra space needed for turning the crank (for those that have them) or opening the lid fully. Weight is another factor to consider, especially if your RV is close to its weight capacity. Lighter models are easier to move around and install but might compromise on capacity.

Ease of Cleaning & Emptying: Keeping It Hygienic
Cleaning and emptying are probably the least glamorous aspects of owning a composting toilet, but they’re crucial. Look for models with user-friendly features like removable urine tanks and easy-access compost bins. Some even have built-in agitators to help mix and aerate the compost, reducing the need for manual stirring. Emptying the solids compartment is usually only necessary every few weeks, but liquids might need to be emptied more frequently, so make sure that process is as hassle-free as possible.

Electric or Non-Electric: Which Is Right for You?
This one’s all about your lifestyle and power setup. Electric models often come with fans and sometimes even heating elements to speed up the decomposition process and control odors. They’re great if you have a reliable power source, either from a battery bank or solar setup. However, if you like to keep things simple or frequently camp without hookups, a non-electric model might be more your speed. They rely on natural airflow and usually require a bit more manual work, but they’re reliable and don’t drain your power.

Additional Considerations: A Few More Things to Think About

• Odor Control: Most composting toilets do a good job of managing odors, but some are better than others. Look for models with effective ventilation systems.
• Ventilation Requirements: Some models require more complex venting setups, which can be tricky in an RV. Make sure the venting options work for your rig.
• Maintenance & Spare Parts: Check if replacement parts are readily available. Some models require proprietary parts, which can be a hassle to find on the road.
• User Reviews: Read up on what others are saying about the model you’re considering. Real-world use can highlight pros and cons you might not think of.

Choosing the best composting toilet for your RV isn’t a one-size-fits-all decision. It’s all about finding the balance between convenience, capacity, and how much “hands-on” time you’re willing to commit. Happy composting, and may your adventures be odor-free and eco-friendly!
