Why Should You Get a Composting Toilet? 

1. You can use them just about anywhere. 

Composting toilets are often purchased by people who are about to go camping, boating, or RVing. This is because they are perfect for outdoor activities because they often don’t require water, they’re very portable, and they’re easy to clean. However, composting toilets can be used not just for outdoor activities. You can use it at home as well, in case you have guests who will be staying in a room that is far from the bathroom. 

2. With a composting toilet, you can be a bit more environment-friendly. 

With a composting toilet, you have the option to not send human waste to sanitation centers. While it may sound gross, you can actually use the waste collected as fertilizer, the same way you can use animal manure. This way, you won’t have to buy chemical fertilizers that may have adverse effects on the environment. 

Things to Consider when Buying a Composting Toilet

1. Storage Tank Capacity 

Composting toilets come in different sizes. Obviously, larger ones have larger storage tank capacities. However, if you’re travelling alone or with just one person, you can survive with a small composting toilet with a small tank capacity. Of course, if you’re coming with your entire family, you have to look for something that can hold a larger amount of waste. 

2. Durability

Look closely at the material that makes up the composting toilet and also think about its weight capacity. Make sure that the composting toilet you’re going to get is made of tough and yet lightweight material, and that it can hold a good amount of weight. 

3. Weight and Size

When getting a composting toilet, think about the size of the space where you plan on placing it, and take that into consideration when deciding what to buy. In addition to that, also think about the weight. If you’re bringing a composting toilet to a boating or fishing trip, you don’t want something that is too big or heavy that it will end up weighing down one end of your boat. Lastly, decide whether the one you’re planning to get is something that is easy to bring or carry. 

4. Maintenance 

Perhaps anything that has to do with toilets is a burdensome chore, but this doesn’t have to be the case when you are having fun outdoors with your composting toilet, as long as you get something that is easy to clean and maintain. 

5. Warranty

Products are often marketed to do an excellent job, but even though they might actually be as great as the manufacturer says, there will always be those unavoidable situations when they turn out to be unable to meet our expectations as consumers or buyers. Thus, it is important that you buy something with a warranty so that if you encounter any issues, you can always contact the store of the manufacturer and get your money’s worth. 

6. Price

The last factor to take into consideration when you’re looking for the perfect composting toilet for outdoor activities is the price. Sometimes, we like something so much until we see the price and realize it’s way above our budget. Then we go and look for something that’s cheaper as long as it does the job. Note that not all cheaper alternatives are bad, however, it’s true that you get what you pay for. When you sacrifice quality to spend less, chances are, you’ll be spending more in the end. Cheap composting toilets are not so durable and they may be more prone to leaks. Thus, make sure to make the right choice. 


When you are planning on going boating or fishing, you should not forget to bring a composting toilet with you. Composting toilets are great because they’re portable and easy to clean. With a good composting toilet, you would not have to cut your boating trip short just so you could do your business.
