How to pick the right portable car toilet?

The biggest mistake people make is that they go out shopping without making a plan. This often leads them to buy the wrong product. while looking for the best portable car toilet, you need to consider a few things so that you ensure you’re making the right choice –


The first and the most important thing to consider while buying anything is your budget. That is because there is a wide range of portable car toilets, starting from $20 to up to $2000. Therefore, if you have figured out your budget, you can make the right choice very easily.

Wet or dry

Some car portable toilets mimic regular toilets, meaning they require a water system for flushing. Even though they use far less water than a regular household toilet, they still need some. If you are looking for a toilet for your RV and have an ample supply of water, you can consider buying such toilets.

On the flip side, there are dry toilets that most commonly come with plastic liner bags. Dry toilets tend to smell a bit, but if your toilet has the suitable absorbent composting material, the smell will be reduced drastically. Such dry toilets can be great for cars and RVs where you don’t have ample water supply.

Raw Waste or Compost

Composting toilets are the best companion for cars and RVs as they keep the odor away while offering the convenience to access your toilet anywhere. However, composting car toilets often cost $1000 or above, making them a very costly solution.

On the other hand, you can buy a toilet stool with some supply of plastic bags. This will cost you nothing more than $50. But this way, you have to deal with your waste. Human waste can have germs and bacteria that can cause diseases. Plus, you will always have odor-related issues.

Environmental Reasons

Even though portable car toilets are great and convenient, they create two major issues. The first one is toilet treatment products, and the other one is disposal bags. Toilet treatment products can be toxic to the soil, and therefore, you need to look for items that don’t cause much damage. Also check these Best Composting Toilets for your personal use.

Similarly, the waste disposal bags made of plastic can be worst for our nature and soil. You can go with biodegradable or compostable bags, though they take years to disintegrate entirely. In such scenarios, composting car toilets become the life savior, but they come at a higher price.

Electrical Requirement

If you plan to go for composting toilets, you need to keep in mind that they require some electric power. They feature built-in fans that help to compost waste material and keep the nasty smell away. Some composting toilets come with batteries included, making them a perfect choice for cars and RVs. Note that some models require consistent electric connection, and you need to connect such toilets from the battery of your RV or car.

Reliance Fold-To-Go Collapsible Portable Toilet

Reliance Fold-To-Go Collapsible Portable Toilet

If you have a very small space in your car or RV, then this collapsible toilet from Reliance can be a good car toilet for you. This toilet just weighs around 5 pounds, and after folding, it sizes just around five inches high. Even though it is made of plastic, it is pretty sturdy and can easily hold a person of up to 100 KG of weight.

Our Opinion: You just need to pack enough doodie bags, and you are good to go.

Similar to the one mentioned above, Camco 41541 is another excellent solution for people looking for portable toilets for car trips. However, the major difference between Porta Potti 92306 and this product is that it doesn’t run on batteries. Instead, it has a pump-type design that you need to pump for flushing. Though the water pressure will not be as strong as a real toilet, it will be sufficient enough to clean the bowl.

Our Opinion: The good thing here is that you can separate the toilet into two halves to carry it around easily.

This portable car toilet comes with a 2.5-gallon flush tank, which is sufficient for 25-30 flushes. You get options to either buy a 2.6-gallon waste capacity tank or the one 5.3-gallon waste capacity tank.

This car toilet is made of high-density polyethylene material that gives it a robust build while maintaining the overall weight to the bare minimum. It has a piston pump design that creates pressure for the flush.

Our Opinion: The thing that impressed me is its three-way flush nozzle that delivers a 360-degree cleaning for the entire bowl.

Closing Comments

These were the best portable toilets for car travel. I hope this article has helped you to make your decision. While shopping for portable car toilets, personal preference plays a very crucial role. However, if you ask me for suggestions, I recommend buying Porta Potti 92306 or Camco 41541 Portable Toilets.

However, these two toilets are going to require some extra space, and if your car or RV lacks that, you can go for Thetford 92859. At last, if your budget is too tight and you ride very less frequently, you can go with Reliance Fold-To-Go or Hassock Portable Lightweight Toilet.
