Best Cassette & Portable Toilet Reviews

1. Camco Portable Toilet

Check Price at Amazon

My Review

The Camco Portable Toilet is a straightforward option for both indoor and outdoor use, making it a great pick for camping, RVs, boats, and cabins. The manual flush system keeps things simple with no batteries or electricity required, while the secure gate valve helps contain odors.

With two tank sizes available, the 5.3 gallon version is the better choice if you want fewer emptying trips and more flushing power. It is also lightweight and compact, making it easy to transport. However, keep in mind that it does not include mounting brackets if you need to secure it in a van or RV, and there is no waste level indicator, so you will have to check manually.

Overall, this is a sturdy and reliable toilet that does the job without extra features. If you need a simple and durable option that works anywhere, this one is a solid choice.

2. Thetford Porta Potti

Check Price at Amazon

My Review

The Thetford Porta Potti is one of the best portable toilets if you’re looking for something that feels as close to a real toilet as possible. With its larger tank capacity, it works well for longer trips, group use, or anyone who doesn’t want to empty the waste tank too often. The battery-powered flush is a nice touch, making it feel more like a standard toilet, and the built-in toilet paper holder and level indicators add to the convenience.

While it’s great for RVs, vans, cabins, and boats, it’s not ideal for outdoor use, since the electric pump isn’t weatherproof. If you need something for camping in remote locations, a simpler manual-flush model might be better. Also, keep in mind that you’ll need AA batteries to power the flush.

If you’re after comfort, convenience, and a toilet that mimics a home setup, this is a great option. But if you need something more rugged for outdoor use, you may want to look elsewhere.

The Thetford Porta Potti is one of the most well-known portable toilet brands among campers. This version is one of Thetford’s largest and most advanced models, offering excellent comfort and functionality for campers, cabins, and more.

3. Alpcour Portable Toilet

Check Price at Amazon

My Review

The Alpcour Portable Toilet is a well-designed option that works for both casual campers and full-time travelers. It has a 5.3-gallon waste tank, which provides plenty of capacity before needing to be emptied, and the manual piston flush is simple and effective. The waste level indicator is a great addition, so you’ll always know when it’s time to dump the tank.

One standout feature is the long hose sprayer, which makes cleaning the bowl much easier than most portable toilets. It also comes with a carry case with handles, which adds convenience for transport and storage. At only 11 pounds, it is lightweight but still supports up to 440 pounds, making it one of the strongest options available.

If you need a reliable, well-built toilet with extra features, this one is a great pick. Just keep in mind that it does not have floor mounting brackets, so it won’t stay secured in a moving vehicle.

4. Camco Premium Travel Toilet

Check Price at Amazon

My Review

The Camco Premium Travel Toilet is a larger, more comfortable option that works well for RVs, boats, cabins, and extended trips. Its 5.3-gallon waste tank and 4-gallon freshwater tank mean you won’t have to empty or refill it as often, making it a great pick for longer use.

The manual hand pump does a solid job at rinsing the bowl, and the watertight gate valve keeps odors locked in. Unlike smaller portable toilets, this one has a larger seat that feels closer to a standard toilet, which adds to its comfort. It also includes a storage bag, making it easier to transport and keep clean when not in use.

While it’s not the most compact option, it’s a great pick for anyone who values comfort and higher tank capacity. Just note that there’s no waste level indicator, so you’ll have to keep track of when it needs emptying.

5. Thetford Cassette Toilet

Check Price at Amazon

My Review

The Thetford Cassette Toilet is a compact, lightweight option designed for solo campers, van dwellers, and road trips. Weighing only 8 pounds, it is one of the easiest portable toilets to carry and move around, making it great for tight spaces like vans and pop-up campers.

With 2.6-gallon fresh and waste water tanks, it is best suited for shorter trips or single-person use. The manual flush system is simple, and the watertight valve helps contain odors. Emptying is also straightforward with the detachable seat and rotating outlet.

If you need a small, easy-to-use toilet that works indoors and outdoors, this is a great choice. However, if you need a larger tank for longer use or multiple people, you may want to look at bigger models.

6. Giantex Portable Toilet

Check Price at Amazon

My Review

The Giantex Portable Toilet is a simple, budget-friendly solution that works well for tent campers, off-grid setups, and outdoor outhouses. Unlike a standard 5-gallon bucket, this toilet includes a full-sized seat and lid, making it more comfortable and familiar to use.

Its lightweight design makes it easy to transport, yet it can support up to 440 pounds. The inner bucket system allows for easy waste disposal with garbage bags, and the lid design helps contain odors, especially when combined with wood shavings or peat moss.

Since it doesn’t have a flushing system, it’s not ideal for indoor use or enclosed spaces. If you need a straightforward, no-maintenance toilet for camping or an outdoor outhouse, this is a great pick.

What To Look For In A Portable Toilet For Indoor Use

Toilet Seat Height

When choosing a portable toilet, the seat height is a key factor for both comfort and practicality. A standard home toilet seat stands about 15 inches from the ground, but many portable toilets include the height of the lid in their measurements, adding an extra inch or two. Most models in this review are close to standard height, though smaller cassette toilets sit lower.

For those with mobility issues, a taller toilet can make standing up easier and more comfortable. Taller models also have the added benefit of reducing the likelihood of bugs reaching the bowl or seat when used outdoors. Keep both storage and comfort in mind when deciding on the ideal height.

Toilet Seat Size

Comfort depends heavily on the size of the toilet seat, especially if you plan to use your portable toilet frequently or for extended periods. A standard toilet seat measures roughly 14 inches wide by 16 inches long, and most of the options reviewed here come close to that size.

Smaller models, like some compact cassette toilets, may have seats that are a few inches shorter or narrower. While these smaller seats save space, they can feel less comfortable. If comfort is a priority, look for a model with dimensions that more closely mimic a standard toilet.

Waste Disposal Process

Disposing of waste is one of the most important aspects of choosing a portable toilet. Cassette toilets require proper disposal, either at a flushing toilet or an RV dump station. Although emptying the tank is straightforward, it involves dealing with raw sewage, which some may find unpleasant. A thorough rinse of the tank is also necessary, which can sometimes get messy.

For those who prefer an easier cleanup process, bucket-style portable toilets lined with garbage bags might be more appealing. These allow you to simply tie up the bag and throw it in the trash. However, this style comes with trade-offs. You’ll need to use materials like wood shavings or peat moss to manage odors, and they lack the cleanliness and comfort of a cassette toilet with a water rinse system. Additionally, bucket-style toilets are best suited for outdoor use, as they cannot fully contain odors when used indoors.

My Pick For Best Cassette Toilet

Camco Portable Toilet

Check Price at Amazon

Since this review is all about the best portable toilets, the Camco stands out as the top choice for overall performance. Its design strikes a great balance between portability, durability, and ease of use, making it a reliable option for a variety of situations.

This model is incredibly portable thanks to its lightweight build and smaller freshwater tank. The quality materials and extra-secure gate valve ensure the waste tank stays watertight during transport, reducing the risk of leaks—an absolute must for any portable toilet.

The manual rinse pump is straightforward and dependable. Although the freshwater tank is smaller, it does not take much water to rinse the bowl effectively, so the compact size works in its favor. Interestingly, this model skips the 90-degree elbow commonly found on other designs. While some may see this as a downside, I actually prefer it, as fewer moving parts mean less risk of leaks—a critical consideration when handling a full waste tank.

The overall design is thoughtfully crafted. While a waste tank level indicator would be a useful addition, checking the tank’s fullness is still simple enough by looking inside. The toilet seat, though slightly shorter than standard, is plenty spacious and offers a comfortable height for most users, even those on the larger side.

This Camco portable toilet combines convenience, reliability, and practicality, making it a fantastic choice for anyone seeking the best in portable sanitation.

Frequently Asked Questions About Cassette & Portable Toilets

Should I Use RV Black Tank Treatment Inside My Portable/Cassette Toilet?

Yes, using a tank treatment in your portable toilet is a smart choice. It helps break down toilet paper and solid waste, making the emptying process much easier and less unpleasant.

One great option is the Happy Campers Holding Tank Treatment (click to view on Amazon), which I personally use in my RV. It is highly effective and works quickly to break down waste while eliminating odors.

What sets this treatment apart is that it contains no dangerous or toxic chemicals, making it safe for you and the environment. It tackles odors and waste without the need for harsh additives, making it a reliable and eco-friendly solution for portable toilets.

Adding a treatment like this ensures your porta potty stays cleaner, smells fresher, and is easier to maintain.

How Does A Porta Potty Or Cassette Toilet Work?

A cassette toilet functions similarly to the flushing toilet in an RV, using a waste tank, a fresh water tank, a toilet bowl, and a seat to create a compact and portable sanitation solution.

To use it, open the valve on the front or side to access the waste tank, which serves as the base of the toilet. After taking care of business, use the manual or electric pump behind the lid to rinse the bowl with fresh water. Once the bowl is clean, close the valve to seal off the waste tank, containing odors and ensuring it remains watertight.

When the waste tank is full, simply detach it from the seat portion and empty it into a flushing toilet, a vault toilet, or an RV dump station. This process is straightforward and allows for proper disposal without the need for a permanent plumbing system.

Cassette toilets are an excellent option for adding a reliable and portable toilet to your camper, van, boat, or cabin. They offer convenience and comfort without requiring complex installations.

What Can I Use For A Pop Up Camper Toilet?

For a pop-up camper, a water rinse cassette toilet is the best choice. These toilets are compact, easy to store, and designed to contain odors, making them ideal for use in smaller, enclosed spaces like a pop-up camper.

Bucket-style toilets, while simple and affordable, are not well-suited for indoor use due to their inability to fully contain odors. Cassette toilets, on the other hand, feature sealed waste tanks and effective odor control, providing a much more pleasant experience.

Another advantage of cassette toilets is their compact size. Many models are short and small enough to be stored under a seat in your camper, maximizing your limited space while still offering convenience and comfort.

Where Can I Empty A Portable Toilet?

Most portable toilets are designed with a detachable base tank that can be emptied in several ways, depending on your location and available facilities.

If you are at home, you can empty the waste tank into your household toilet. Be sure to flush multiple times to prevent clogs, especially if the tank contains thicker waste. While this method is straightforward, it can be a bit tricky and requires extra care to avoid spills.

At campgrounds, vault toilets are a convenient option for emptying your portable toilet, as long as it only contains organic waste, water, and toilet paper. Avoid dumping anything with chemicals that are not biodegradable.

RV dump stations are another great choice. These are specifically designed for waste disposal and are often equipped to handle larger tanks, making the process quicker and easier.

For extended stays in the wilderness, consider using a portable waste tank. These tanks typically hold up to 30 gallons of wastewater securely. You can empty your portable toilet into the waste tank and later dispose of the contents at an RV dump station.

To make the process smoother, use plenty of water and a tank treatment in your portable toilet. This helps break down toilet paper and solid waste, reducing clogs and making the tank easier to empty.

How Does the Height of a Portable Toilet Compare to a Regular Toilet?

A standard regular toilet has a seat height of about 15 inches. Some models, often referred to as “comfort height” or “chair height,” are slightly taller, which can make standing up easier for older adults or those with mobility issues.

Portable or cassette toilets vary in height, with seat heights typically ranging from 12 to 17 inches. This makes it possible to find a model that fits your needs, whether you prioritize compact storage or added comfort.

When choosing a portable toilet, it is important to consider both the height and capacity. A slightly taller seat height is generally more comfortable and practical, especially for those who may have difficulty getting up from lower seats. Taller models also tend to mimic the feel of a standard toilet more closely, which can enhance the overall experience.

Why Should You Empty Your Portable Toilet Before Leaving It for More Than a Few Days?

Portable toilets are designed to be completely sealed, preventing odors and leaks during use. While this is a fantastic feature, it is important to understand what happens to the waste over time. As sewage waste breaks down, it naturally releases gases. If left in the toilet for an extended period, these gases can create pressure inside the sealed tank.

Pressure buildup can lead to unpleasant surprises, and there are stories from campers who left their portable toilets full during summer storage only to return to a messy and unpleasant situation.

To avoid this, always empty your portable toilet after every trip. Not only does this prevent pressure buildup, but it also makes the tank much easier to clean. The sooner you empty it, the less likely you are to deal with hardened waste or lingering odors. Regular maintenance ensures your portable toilet stays fresh and ready for your next adventure.

Why Is My Portable Toilet Difficult to Empty?

The most common reason for a portable toilet being hard to empty is insufficient water in the wastewater tank during use. A lack of water makes it difficult for solid waste and toilet paper to break down properly, leading to clogs and a tougher emptying process.

Before you start using your portable toilet, always add about a gallon of fresh water to the wastewater tank. Including a tank treatment product is also crucial, as it helps break down solid waste and toilet paper, making the entire process smoother.

Another common mistake is avoiding the use of rinse water or only using the toilet for solid waste. While this might seem like a way to conserve water, it actually makes things harder when it is time to empty the tank. Portable toilets rely on a good amount of liquid to keep everything broken down and moving easily during disposal.

In short, to make emptying your portable toilet hassle-free, ensure you start with enough water in the tank, use a quality tank treatment, and don’t skimp on rinse water during use. Proper preparation and maintenance will save you a lot of trouble later.
