What Is This RV Composting Toilet Thing You Speak Of?

Any RV owner knows that one of the challenges of life on the road is finding a place to dump your waste. That’s where a composting toilet comes in handy. Essentially, it’s a small chamber that you can use in place of a traditional RV toilet. Waste is collected in the chamber, and over time it breaks down into compost. This compost can then be used as fertilizer for plants. While composting toilets may take some getting used to, they’re a great way to reduce your impact on the environment. And who knows? You might even end up with a nice bumper crop of tomatoes by the end of the season (hahaha)!

If you’re considering making the switch to a composting toilet for your RV, you might be wondering what about the smell? After all, one of the main reasons people choose RVing is to enjoy the great outdoors, and not smell like an outhouse. However, the odor is not actually a problem with composting toilets. In fact, it’s a common misconception. The truth is that a properly maintained composting toilet will not smell any worse than a regular flush toilet. In fact, it may even smell better since there are no sewage odors. So if you’re worried about the smell of your RV’s composting toilet, don’t be. It’s not an issue.

How Does It Work?

A composting toilet sounds like it would be a stinky, fly-ridden outhouse. But surprisingly, these toilets can be found in some of the most luxurious places – think high-end vacation homes and private jets. So how do they work? Composting toilets use natural processes to break down human waste. The waste is deposited into a chamber where it is mixed with sawdust, wood chips, or other organic matter. This material helps to absorb moisture and odors while allowing oxygen to circulate, which speeds up the decomposition process. The resulting compost is safe to use on gardens or lawns. And there’s no need to worry about pests – the high temperatures generated by the decomposing waste prevent flies and other insects from taking up residence.

Liquid Waste:

Liquid waste is a bit more complicated. Composting toilets can’t handle liquids, so they need to be diverted to another container. This container can be a traditional black water tank, or it can be a holding tank that is specifically designed for composting toilets. The liquid waste from the toilet needs to be emptied every few days, and it can be disposed of in the same way as black water from a traditional RV toilet.

Solid Waste:

Solid waste can be composted in the same way as liquid waste, but it’s important to make sure that the material you use to absorb moisture and odors is dry. Composting toilets work best when the waste is thoroughly dried before being deposited into the chamber.

Benefits Of Having a Composting Toilet

If you’ve ever been on an RV trip, you know that one of the most important things is to have a reliable toilet. Not only do you need a toilet that will be comfortable to use, but you also need one that won’t cause any environmental damage. That’s where composting toilets come in. Here are some of the benefits of having a composting toilet for your RV:

Boondocking and Off-Grid Living:


A composting toilet saves you from having to deal with smelly, messy sewage tanks and gives you a more environmentally friendly way to dispose of human waste. Plus, it means you can stay out in the boondocks for longer without having to worry about finding a dumping station

No Blackwater Tank:

If you’ve ever RV’d before, then you know that one of the least glamourous aspects of the experience is dealing with the black tank. This is the tank that stores all of your sewage, and it needs to be emptied on a regular basis. Trust me, you don’t want to get black tank problems. That’s why I was so excited to discover that there’s such thing as a composting toilet. This means that you don’t have to deal with a black tank at all! The toilet breaks down your waste into compost, which can then be used as fertilizer. It’s a much cleaner and more environmentally friendly way to deal with human waste. Plus, it saves you from having to deal with that pesky black tank.

Less Water Usage:

Of all the things that people want in their RV, a composting toilet is probably not at the top of most people’s list. But what if I told you that having a composting toilet in your RV could actually save you money? That’s right, a composting toilet can help you use less water, which means you’ll save money on your water bill.

 If you are planning to take your RV off-grid for an extended period of time, a composting toilet can be a great way to be more eco-friendly. Composting toilets break down human waste into compost, which can then be used as fertilizer for plants. This means that you won’t have to deal with the waste from your RV, and it also reduces the amount of sewage that goes into the environment. 

Less Odor:

There are many reasons to choose a composting toilet for your RV. Perhaps the most important reason is that it produces less odor than a traditional toilet. This is because the composting process breaks down waste material, reducing the amount of methane gas that is produced. In addition, a composting toilet typically has a venting system that helps to further reduce odors. As a result, you can enjoy your time on the road without having to worry about unpleasant smells.

What Is Not So Great About Having A Composting Toilet?

There are a few downsides to having a composting toilet in your RV. What? You thought it was all roses and skipping. Nothing really works that way. So here are the downsides. Sorry to burst your bubble sunshine.


Anyone who’s looked into composting toilets knows they can cost a lot of cheddar. For example, the Nature’s Head self-contained composting toilet costs over $1000. The Separett Villa 9010 costs over $2000. And the Clivus Multrum M41 costs a whopping $4000! Of course, you could always build your own composting toilet, but then you’re looking at spending hundreds of dollars on materials. So unless you’re flush with cash, you might want to hold off on investing in a composting toilet.

They Don’t Come Installed:

If you’re in the market for a new RV, you might be disappointed to learn that most models don’t come with composting toilets installed. That’s right – if you want to enjoy the convenience of a composting toilet, you will have to install it yourself or pay someone else to do it for you. Of course, you could always just stick with a traditional flush toilet, but where’s the fun in that? Besides, why not take advantage of all the modern amenities that an RV has to offer? After all, isn’t that what camping is all about? So go ahead and splurge on that composting toilet – you’re sure to be glad you did!

Awkward Size and Shape:

When you’re out on the open road, the last thing you want to worry about is your bathroom situation. Unfortunately, this can be a problem with some composting toilets, which often come in awkward shapes and sizes. This can be especially true for RV bathrooms, which are often smaller than brick and mortar bathrooms. As a result, it can be difficult to find a place to put a composting toilet that won’t take up too much space or cause problems with the layout of your RV. However, there are some companies that make compact composting toilets that are specifically designed for RVs. So if you’re looking for a way to compost your waste while on the road, be sure to check out these options.


If you’re considering using a composting toilet in your RV, there’s one important thing to keep in mind: in order for them to work efficiently, you will need proper ventilation. This may require some engineering on your part, depending on the layout of your RV bathroom. But trust me, it’s worth it – a composting toilet can be a game-changer on long road trips. Not only will it save you from having to make frequent pit stops, but it will also help reduce your impact on the environment. So if you’re willing to put in a little work up front, a composting toilet might just be the perfect solution for your next RV adventure.

How To Get Rid Of The Waste

If you’ve ever wondered how to get rid of waste when dealing with a composting toilet, the answer is actually quite simple. For liquid waste, all you need to do is pour it into the liquid waste container. For solid waste, you’ll need to scoop it into the solid waste container. And that’s it! Once you’re done, simply seal up the containers and put them in the appropriate garbage bin. Of course, if you’re feeling particularly green, you can always compost the waste yourself. But for most people, the easiest way to get rid of waste is to just throw it away.

Can I Use Regular Toilet Paper? 

Toilet Paper

Can I Use Regular Toilet Paper in a composting toilet? The answer may surprise you! While regular toilet paper can technically be used in a composting toilet, it’s not the best idea. Composting toilets rely on a balance of nitrogen and carbon to break down waste. Regular toilet paper is high in carbon, which can throw off the balance and make the composting process less efficient. In addition, regular toilet paper is often treated with chemicals that can be harmful to plants. So while you technically can use regular toilet paper in a composting toilet, it’s not the best choice. If you’re looking for a more environmentally friendly option, there are plenty of brands that make compostable toilet paper. Just be sure to check the labels to make sure it’s compostable.

What To Consider When Shopping For A Composting Toilet For RVs

If you’re in the market for a composting toilet for your RV, there are a few things you’ll want to keep in mind. First, consider how often you’ll be using the toilet. If you’re only going to be using it on occasional camping trips, you might not need a super high-end model. However, if you’re planning on living in your RV full-time, you’ll want something that’s durable and easy to use.

Price/ Cost:

Another thing to consider is price. Composting toilets can be expensive, especially the high-end models. So if you’re on a tight budget, you might want to opt for a more affordable option.

Size and Shape:

Also, keep in mind the size and shape of the composting toilet. As I mentioned earlier, this can be a problem for some RVs. So if you’re having trouble finding a model that will fit, be sure to ask the manufacturer before making a purchase.


Keep in mind that composting toilets require some basic maintenance, such as emptying the waste containers and cleaning the toilet bowl. So if you’re not comfortable doing this yourself, be sure to ask the manufacturer about their recommended maintenance schedule.

Ease of Use:

Consider how easy the composting toilet is to use. Some models are notorious for being difficult to operate, while others are practically self-explanatory. So if you’re not particularly mechanically inclined, it might be wise to go with a simpler model.


Finally, if you’re not comfortable installing a composting toilet yourself, be sure to ask the manufacturer about installation options. Many companies offer installation services, or at the very least, can recommend someone who can help.

Conclusion To Composting Toilet For RV
