10 Best & Most Practical Cassette Toilets (in 2021)

So you don’t want to give the forest nearby a long-awaited visit? Well, a cassette toilet is your best bet. Let’s take a look at 10 of the best toilets.

It’s 2:39 a.m. and you’re awakened by the strong sensation of having to pee, likely caused by the one gallon of Coca-Cola you were mixing with rum mere hours before going to bed. Shouldn’t have done that!

You try to refocus on falling back asleep but your bladder feels as if it might burst if you don’t visit the bathroom as soon as possible.

Unfortunately, you’re in an RV without a toilet so the nearest bathroom is actually an outhouse found about 8 campsites down the road.

You have two options. You can either pee in the forest behind your RV or tackle the dark journey to the nearest outhouse. If you relieve yourself in the bushes near your picnic table, chances are that you’ll smell wafts of it the next day.

But your ability to navigate uneven terrain is subpar at even the best of times, which makes you nervous about traversing roots and rocks in the pitch black.

You think to yourself, “if I had a portable toilet, I wouldn’t be in this position.”

Immediately after returning from your spooky adventure to the smelly outhouse, you add “order a cassette toilet” to the to-do list found in your notes. We’ve all been there.

So, here are the 10 best cassette toilets in 2021:

  1. Zimmer 5 Gallon Cassette Toilet

1. Zimmer 5 Gallon Cassette Toilet

Nature calls numerous times per day, which is why you need a portable toilet that is comfortable, flushwable, leak proof, and easy to use. This portable toilet features a 3-gallon freshwater holding tank and 5-gallon wastewater holding tank. The toilet’s pump allows people to use 50 to 70 flushes before the waste tank is full and needs to be dumped. The portable toilet has a valve on the side that closes tightly before and after the waste is expelled, which minimizes odors and combats leakage. But for the most smell-proof experience, the portable toilet company suggests purchasing additional deodorizing tablets. The toilet weighs less than 10 lbs and can be transported by the handles on either side.

2. SereneLife Outdoor Cassette Toilet

All hail the SereneLife travel toilet as it comes with a wastewater tank level indication so that you don’t need to track the flushes or open the tank to check how much room is left. The tank holds a whopping 5.3 gallons and can be emptied without a mess thanks to its splash-free rotating pour spout. Sounds lovely, doesn’t it?

A customer review notes that this toilet was handy during the pandemic as their family didn’t have to visit the public washrooms, making it easy for them to follow social distancing guidelines.

The portable toilet, ideal for traveling and road tripping, also has a double-sealed drain valve to prevent leaks and nasty smells from taking over your RV.

3. Camco Premium Cassette Toilet

This portable toilet’s claim to fame is its three directional flush and swivel dumping elbow. The three directional flush function makes sure that the toilet bowl is flushed clean every time, reducing odors and making the experience more enjoyable. Both the holding tank and the toilet lid seals tight to ensure that there is no mess when the vehicle is moving. The Camco Premium Portable Travel Toilet can hold up to 5.3 gallons of waste. The toilet weighs around 12 lbs when empty and approximately 56 when full. I hope that the person who tested this was appropriately compensated.

4. Dometic 5 Gallon Cassette Toilet

This cassette toilet features a hookup for discharge and is the best option for solo travellers as it comes in a 2.5-gallon model as well as a 5-gallon model. It’s easy to clean and is constructed with scratch-resistant polyethylene materials. The Dometic Portable Toilet is square-shaped and weighs around 11 lbs when it isn’t filled with human waste.

One customer notes that they use the blue deodorizing chemical in their Dometic Portable Toilet and it works like a charm.

5. Thetford Corp 365 Cassette Toilet

If you’re a sucker for appearance, then you’ll love this fancy and modern portable loo. The Thetford Corp White Porta Potti easily separates so that you can empty the tanks. Each tank has a carrying handle and a pivoting pour-out spout to ensure the process is free of any messes. This model has tank level indicators to let you know when the built-in freshwater tank needs to be filled or when the wastewater tank needs to be emptied. Even though you won’t need to track flushes, this cassette toilet can accommodate around 56 flushes before the tank needs some attention. This toilet is taller than most cassette or portable toilets, which makes it more comfortable when using.

A happy customer notes that they went with this portable toilet because of the customer service that the Thetford Corp brand provides. Similar to hammock stands and tent heaters, when it comes to portable toilets, you get what you pay for.

6. Earthtec ETEC Non-Stick Cassette Toilet

In the portable toilet world, Earthtec is a big name best known for its commitment to developing environmentally friendly solutions. The Earthtec ETC Portable Toilet features a 5-gallon holding tank with  rotating pour spout that combats mess when getting emptied. The air-tight lid locks in odors and the toilet’s non-stick bowl, made with nanotechnology polymer, further ensures that users have a sanitary experience. This product does not have a tank level indicator but it can be used for up to 50 flushes before the tank needs to be emptied.

7. Reliance Flush-N-Go Cassette Toilet

This brand has been around for almost 45 years, which speaks to its reputation and quality of products. The Reliance Flush-N-Go Toilet features a 2.5-gallon waste tank, making it a perfect option for solo travellers. The toilet comes in black, grey, and white but due to the pandemic, customers are unable to specify which color they would like. This portable toilet runs on fresh water and has a spout that makes the wastewater disposal easy and mess-free.

Customer reviews note this product keeps all the smells inside, especially if you use a deodorizing solution. Some people have suggested that it’s easier to use the toilet if it’s sitting on something else as it is quite low to the ground. If you’re camping and are looking for a basic and affordable portable toilet model, Reliance also makes a toilet that empties into a bucket. However, it is currently out of stock.

8. YITAHOME Cassette Toilet

This cassette toilet is constructed out of environmentally friendly materials and features a 3.2-gallon freshwater holding tank and a 2.6-gallon wastewater holding tank. The RV toilet has an upgraded dual outlet spout and it’s pump handle pushes water to clean the entire bowl. The YITAHOME Portable Travel Toilet also has a built-in slide valve that is thoroughly sealed to lock in odors and prevent leakage. The portable RV toilet is extremely lightweight but can hold up to 275 lbs.

If you’re a fan of sealed side valves to prevent leakage, then this is the portable toilet for you. The SEAFLO toilet is self-contained and can be easily transported into and out of your RV. It weighs less than 10 lbs when empty and despite being incredibly lightweight, it can comfortably hold up to 330 lbs. When it comes to emptying the tank, the toilet has a rotating spout that makes it a mess-free experience. Customer reviews note that it sits quite low to the ground so it’s recommended for people with adequate squatting abilities. For older campers, I suggest opting for a portable toilet that is higher for easier use.

This portable toilet comes in two different tank size options: 2.6-gallon or 5.3 gallon.

10. Flexzion Portable Cassette Toilet

Last but certainly not least is the Flexzion Portable Camping Toilet that features a 5-gallon holding tank, the ability to flush, sealing slide valves to prevent spilling and odor, and sturdy side latches that securely hold the tank to the toilet. Made with high-density Polyethylene, the portable toilet is environmentally friendly, comfortable, and shockproof. Both the 3.2-gallon water tank and the 5.3-gallon wastewater tank are detachable and can be carried by handles.

One happy customer states that their husband said emptying the tank “wasn’t a horrible experience” and that they chalk that up to a big win as emptying a tank filled with bodily fluids is never a fun job.

What to Consider When Purchasing a Cassette Toilet?

When looking for a suitable cassette or portable toilet, there are several things to consider:

The tank size

The tanks within most cassette or portable toilets tend to be on the small side so try and find a model with the largest tank possible. This way you won’t have to do the glamorous task of emptying it on a daily basis. However, if you’re travelling in your RV alone, you may not require such a large tank. It’s also important to consider the weight of the portable tank when it’s full as you’ll need to carry it to the dumping station.

The lid

When searching for a good portable toilet, a locking lid is crucial as it will help minimize the smell but also will avoid any messes when the RV is in motion. Most people spend lots of time in their RVs so you don’t want it smelling like literal sh*t.

Does the tank have a level indicator?

Some cassette and portable toilets require it’s users to keep track of how many flushes have been used as this can indicate when the tank is getting full. However, if there are multiple people using the toilet on a daily basis, keeping track of the flushes can feel like a full-time job. If you’re not interested in keeping a small tally sheet and pencil in the bathroom, try to find a cassette toilet that has a tank level indicator so that you can easily see when it is full.

Features for easy transportation

Since you’ll be lugging the tank out of the RV and into the nearest public bathroom or dumping site, it’s helpful if the tank has a handle or is on wheels. This will make the rather unpleasant task slightly more pleasant.

Final Thoughts

Bringing a cassette toilet with you on your next trip comes with a bunch of benefits. You won’t have to visit the site’s restrooms or squat down in some forest nearby. These 10 cassette toilets are by far the toilets I’d take a look at if I were to buy one. Good toilet hunting!
