You’ve probably never given it much thought, but camper toilets do not work like your typical home toilet.
This is important to understand if you plan on using a toilet in your new RV or camper.
So, if you’re looking to get into the RV lifestyle or are just generally curious, we’ll show you exactly how the different types of camper toilets work.
Plus, we’ll answer those burning questions, like whether you can poop in a camper toilet or not!
Types of Camper Toilets
To understand how a camper toilet works, you must first understand that there are a few different types of toilets you can use, each dealing with “waste” differently.
Let’s look at three of the most popular types of RV toilets and learn how each works. There are a few other types, like incinerator and macerating toilets, but below we cover the three you’re most likely to run into.

Gravity Flush Camper Toilets
A full camper toilet is essentially a toilet that empties into the black water tank. You’ll typically find these types of toilets in RVs, 5th wheels, and motorhomes with a dedicated bathroom.
When looking at this type of toilet, or any type of camper toilet, you’ll immediately notice they are different than a home toilet.
First, full camper toilets don’t have standing water in the bowl. You’ll also notice they don’t have your typical flush handle at the top of the toilet. Instead, most models have a handle or lever near the bottom that you can flush with your foot. And some models have what looks like a kitchen sink sprayer attached to the side of the bowl.
How They Work
As you stand over and peer in the toilet bowl, you’ll notice a sealed drain. When you flush the toilet, water is pulled from your vehicle’s fresh water tank into the toilet bowl, and the drain seal opens, allowing the water to flow into the black tank. When the black tank gets full, it is then emptied at an RV dump station.
Tip 1: Before using the toilet, be sure the bowl is around 1/4 of the way full with water. This will help ensure all the waste is properly flushed into the black tank. It’s a good idea to add the water when you’re done so it’s ready to go for the next person.
Tip 2: Use rapid-dissolving toilet paper. This may make it easier to clean out your black tank later and prevent clogs.
Tip 3: Ok, one final important tip. Cleaning an RV toilet is also different than cleaning a regular house toilet! Check out our complete guide on how to clean an RV toilet for all the important details.
Portable Camper Toilets
Unlike full camper toilets, a portable toilet does not require your RV or motorhome to have a water tank or black tank to empty into. It’s all handled within the toilet itself.
You will likely find these “porta potties” in smaller campers, travel trailers, pop-up campers, or any unit that doesn’t have water tanks. You can even use them outside!
How They Work
In most models, freshwater is held in the upper tank of the toilet itself. When you flush the toilet, the water empties out of the upper tank, into the toilet bowl, and then flows down into the lower part (or base) of the toilet. You can pull out the bottom waste tank and empty it into a regular toilet when it’s full.
Composting toilets are similar to portable toilets in that they don’t require your camper to have any water tanks. But, unlike portable or full camper toilets, they don’t require any water (well, just a little water to hydrate the composting additive)!
Plus, they compost your solid waste, which can be used as fertilizer. This and the water savings make it the most eco-friendly toilet option.
And did we mention they don’t give off a foul smell?!
How They Work
These toilets have a chamber near the back filled with composting material like peat moss or coconut fiber. After doing your duty, liquid waste is separated from solid waste. The liquid goes into a special compartment that can be emptied, and the solid waste goes into the composting chamber. Lastly, turn a handle located on the side two to three rotations to mix the waste with the compost material.
Once it’s full, you can empty the liquid waste down a regular toilet (or in a safe manner), and the compost waste you can use as fertilizer. Just be sure to check with state or local laws on disposing of this waste.
Tip: If your bowl gets a little dirty, use a spray bottle with a mix of water and vinegar to assist particles down.
