My Sun Mar GTG Composting Toilet Review (+6 Pros & 2 Cons)

Introduction to the Sun Mar GTG Composting Toilet

Whether we like to admit it or not, the environment is an essential part of who we are and how we can continue living as a species. Even if you live in a large city, the fact is that the city you’re in is located where flora and fauna once flourished. Since our species has an enormous influence on the overall health of our planet, a lot of it falls as our responsibility. How much of that responsibility falls on our own shoulders depends on the person. Speaking of helping the environment, our everyday use of our bathroom negatively affects the environment a lot more than a lot of us might realize. More specifically than the bathroom, our toilets play a significant role in hurting the planet. To discuss this issue more depth, we’re going to do a review of the Sun Mar GTG Composting Toilet.

When you take a look at a composting toilet, it’s important to highlight the efficiency of it first before anything else. You can technically buy any composting toilet to be eco-friendly, but if it operates horribly, then there’s no point. This specific composting toilet operates very well. Not only is it a standard composting toilet, but it’s completely portable. Since it’s portable, you can use it on your RV or with you while you camp.

I can see it’s portability being a massive positive for those of you who enjoy camping. Plus, it has a great compact size to it, which makes it incredibly easy to bring with you anywhere. Something can be portable, but if you can’t move it quickly, what’s the point? The installation of it can be done very fast. You basically just have to make sure it’s in place properly and have everything it needs. This will only take a few minutes, and it’ll be ready to go for anyone to use.

With its actual operation, it manages to separate liquid and solid waste into two separate chambers. This function makes it easier for you to dispose of any waste you see fit. Plus, without the use of hazardous chemicals or extra water, it’s significantly better for the environment than a standard toilet or a porta-potty. The built-in fan on the toilet was a nice touch. We all know about the odors that can come from toilets, but the built-in fan certainly helps with this issue.

Size-wise, it’s tremendous. Minus the water tank of a standard toilet, this toilet is actually larger. Usually, composting toilets have a smaller size to them, but this one is a great size. All in all, this is an excellent composting toilet. For my main negatives, I wish it had a return policy attached to it since a bit pricey. I also wish it was more like a composting toilet that operates as one, but it works well, so I can’t complain.

Pros of the Sun Mar GTG composting toilet

  • Excellent size to it. Usually, composting toilets are tiny, but this wasn’t.
  • The built-in fan was unexpected but turned out to be a fantastic addition. It definitely helped eliminate unwanted smells.
  • It separated liquid and waste very quickly. This function alone is how the toilet can operate effectively.
  • It’s straightforward to install and use. We all know how annoying of a product it’d be if it took forever to use.
  • Portability is always a massive benefit in my mind. It allows you to use the toilet in your RV or if you’re camping very quickly.

Cons of the Sun Mar GTG composting toilet

  • Considering the price, I wish it had a return policy. Although most of you won’t run into any significant issues with it, it’s a bit pricey, which deserves a return policy.
  • It doesn’t have an exact composting function. Although it’s still a lot better for the environment than a standard toilet, it doesn’t have a true composting capability like some composting toilets.


After an in-depth look at this toilet, I can say it’s an excellent toilet and is definitely worth the price. I love how portable and compact it is. It makes it very easy to bring anywhere, which is always a massive positive. Plus, it’s easy to install. The quality of it is excellent, and you can tell it’s built very well. It should last you a long time, and I don’t see any significant issues with it down the line. It splits off the liquid and wastes very quickly, which allows you to throw both out when needed.

If you’re a big-time camper or road-trip traveler, this is an excellent composting toilet for you to check out. As noted, I wish it had a return policy and a better composting capability attached to it, but this isn’t the end of the world. Be sure to check it out for yourself and see how you like it. Now that our review is finished, let’s go over a bit of other information about composting toilets like the Sun Mar GTG composting toilet!

What is a Composting Toilet?

For those of you that don’t know, generally speaking, a composting toilet works as a way to turn waste into compost. It does so in a way that doesn’t use any harmful chemicals but instead creates an oxygen-rich area that forces aerobic bacteria to dispose of the waste. Because of its ability to do this, composting toilets are significantly better for the environment than standard toilets. Plus, composting toilets don’t require anywhere near the same amount of water standard toilets use.

Most composting toilets are relatively the same, but they come in two different variations. A self-contained composting toilet works entirely on its own. This means it doesn’t require an additional hand except for the occasional maintenance. A central composting toilet works by sending the waste and liquid to a separate container. The Sun Mar GTG Composting Toilet review above is a central composting toilet.

Which kind of composting toilet you should consider using depends on what you can afford and what is available. Either type will play a significant role in helping the environment toward a better future.

The Benefits of a Composting Toilet

Other than environmental benefits, there are a lot of benefits tied to a composting toilet. In case the environmental factor isn’t enough for you to consider buying one, let’s go over a few other benefits of one.

Saves Money

Surprisingly enough, a composting toilet can save you a lot of money. Since composting toilets don’t require water like standard toilets, they can save individuals quite a bit of money on their plumbing bill.

Although it might not seem like a lot at first, as time passes, you’ll see a significant difference in the amount of money you save with a toilet like this. Who doesn’t love saving money? Always a huge plus in my mind.

Water Preservation

With the notion of saving money in mind, saving water is a huge benefit in and of itself. As humans, we have a natural tendency to be more wasteful than we should. Having a product that can help with water preservation is always a huge benefit. Not only will you save money, but it’ll help you save water. Most people would classify that as a win-win.


This might sound a bit too grotesque, but technically speaking, you’ll get some compost to use from your composting toilet. If you live on a farm or have a garden, having some free compost can be very beneficial to you.

This obviously depends on the composting toilet in order for it to work correctly, but how cool is that? Imagine having a massive garden with your own “home-made” compost as the fertilizer. That sounds odd, but you know it’d be kind of cool.

When Do People Use a Composting Toilet?

Outside of just the overall benefits of a composting toilet, there’s plenty of situations that might cause a person to use a composting toilet. Let’s go over what those situations are.

Septic Options Aren’t Available

At one point or another, a lot of people want a change in scenery and live a low-key life. To achieve this, people tend to look into septic options. However, with a low-key life off the grid, a septic tank is costly and usually isn’t always possible to do.

This all depends on where the person ends up living and how the land is around them. If it turns to not be possible, then that is where a composting toilet comes in handy. It achieves the same goal of being completely independent and separate from society. It sounds like a unique and exciting way of living for me.

Plumbing Isn’t Available.

If you own a cabin, an RV, or are planning on a trip to go camping, plumping isn’t available for you. Because of this, a lot of people turn to composting toilets as a solution for them to use the bathroom in areas that don’t have any plumbing.  It’s a great option to have. We all know how fun camping or being in an RV is to have, so why not have a composting toilet? It’ll be that perfect solution for the times you need a bathroom, but there isn’t an option available.

If you can manage to buy a portable composting toilet like the one above, then you can bring it with you on any trip that requires a toilet.

Water is Scarce

Depending on where you live, you might or might not understand that water is scarce in certain areas around the world. If you live in an area that doesn’t have a lot of water, as noted, an excellent way to save water is with a composting toilet. It’ll save a good chunk of water every single day. That water you would’ve used for your toilet can be used for something more beneficial now.
