9 Best RV Cassette Toilet For Rvs, Campervans & Van Living – 2022

Finding a suitable, comfortable cassette toilet for your RV or campervan is crucial. 

While some people are quite happy managing public restrooms or the great outdoors, others want a functioning toilet they can use in the comfort of their RV.

One option is a cassette toilet, sometimes called a cartridge toilet. It’s not entirely portable, and unless you retrofit a SOG kit, you’ll still need to use chemicals to control odors.

However, they’re more budget-friendly than expensive composting toilets, and their design means you don’t need to carry waste through your living area. 

If you’re looking for a cassette toilet for RV living or your campervan vehicle, here are some of the best options and some portable chemical toilets.

 A Thetford cassette toilet is one you can rely on.

Specification

  • Material: Resin
  • Item Dimensions LxWxH: 16 x 16 x 12 inches
  • Holding Tank: 5.3 gallon holding tank is detachable for easy emptying

This durable portable travel toilet from Camco is sure not to leak. The tank is sealed firmly, so no smells will escape while you’re traveling. It uses a bellows-type pump to flush and can hold over 5 gallons of wastewater. 

Be aware that when completely full, this can weigh up to 25kg, and it has no wheels, so it will need to be carried to the dump – you may wish to empty it more frequently.

The small size only has a 2-gallon waste tank but bear in mind that at a little over 12 inches, it’s really short, so you’ll need to squat when using it. The 5-gallon version featured here is a more practical option.

PROS

  • Great as an emergency option
  • Seals tightly to prevent both leaks and odors
  • Compact and lightweight

CONS

  • Difficult to empty-weak water pump

9. Dometic CTW 4110 Cassette Toilet

  • Holding Tank: 4.2 gallon

For that real home-away-from-home toilet, this Dometic model may be expensive, but it’s incredibly comfortable. 

The ceramic inlay is easy to clean but weighs less than a whole ceramic toilet, while the high-power flush system keeps everything nice and sanitary. 

The seat can rotate up to 90 degrees for total comfort in smaller areas.

The 4.2-gallon waste tank is a good size, while it has a simple control panel on the waste tank to make it really easy to use and empty.

How Does a Cassette Toilet Work?

A cassette toilet works in much the same way as any other portable chemical toilet. 

You’ve got an upper tank that you fill with water and a wastewater tank that you add chemicals to. 

Once you’ve used the toilet and flushed it with clean water, the waste goes into the lower tank, where the chemicals break it down.

The difference with a cassette toilet is that you then empty the cassette or cartridge from an internal access door, or more commonly an external hatch, rather than having to carry the tank through your living area.

The tanks often have wheels or carry handles to make this easier.

Pros of a Cassette Toilet

The main advantage of a cassette toilet is that it’s a permanent solution – you can install it and have a properly working toilet in your own mini bathroom space. 

For many people, this helps them feel more comfortable – instead of a portable toilet taking up living space, you instead have a dedicated toilet space.

They’re also cheaper than composting travel toilets. So if you want a permanent toilet in your RV or campervan but have a budget you’re working to, then a cassette might be the best solution.

And while cassette toilets by default aren’t eco-friendly, you can retrofit a SOG. These kits use small, low-power fans to draw odors away from your bathroom area into the cassette.

SOG 2 kits instead vent outside the vehicle, either through the floor or the roof. Either way, the result is a toilet that doesn’t smell without the need for harsh chemicals.

Cons of a Cassette Toilet

Unfortunately, cassette toilets aren’t perfect, and there are a lot of things to consider before you buy one. 

Firstly that issue around needing chemicals if you don’t upgrade with a SOG kit. 

Chemicals aren’t always easy to buy when you’re traveling, and even when they are available, they can be expensive. Plus, you need to find a proper dumping station.

Even when you find a dumping station for your chemicals and waste, it’s not exactly a pleasant job, and it isn’t always an environmentally friendly option.

Plus, while they’re cheaper than composting toilets, they’re much more expensive than a standard portable cassette toilet, and they’re trickier to fit, too – you’ll need to install your own access hatch into the van wall.

Cassette Toilet Size

Cassette toilets come in different sizes, and while you can read about their weight when you choose which one to buy, you need to remember that they’ll weigh a lot more when they’re full. 

They do have wheels and handles, though, so you aren’t expected to carry them, and you can empty them before they’re full too.

Still, if you want a more maneuverable one, look for options with a smaller capacity – you’ll need to empty them more frequently, but they won’t be as difficult to transport to the dump when full.

Features To Look Out For

Some of the optional or varying features to look out for with a cassette toilet are:

Flush Type and Nozzles

Cassette toilets will either work with a manual pump flush or with a battery. If you choose the battery, you’ll need to keep it charged, while the manual one just needs a little bit of work every time you use it. 

Many cassette toilets have one flush nozzle, but some have up to three, which is usually cleaner – more water across more of the toilet’s surface means it’s more likely to clean waste away in one go.

Fill Indicators

Because the cassette is stored below the toilet and accessible from an external hatch, it’s not always obvious when it’s full and needs to be emptied. 

Some cassette toilets have indicators to let you know when they’re full. 

Carry Handles & Emptying Spouts

Emptying a cassette is never pleasant, so look for one that makes carrying them to the dump easier. You’ll also want an easy-pour spout because nobody wants splashbacks from their toilet.

Other Toilet Options

portable cassette toilet

There are campervan toilet options to suit every budget. 

Collapsible camping toilets are really simple, essentially a seat with a hole. Add in a biodegradable bag (or two – double lining is always a good idea), and you’re good to go. 

Easy, very cheap, ideal for small campers or car camping but not the most comfortable, nor the best at keeping things sanitary.

Portable chemical toilets are the same as cassette toilets, except that you can move them around. This means there’s no complicated installation in your RV or campervan. 

Emptying one is a little trickier, and you need to be careful if you carry them through the rest of your van.

Composting toilets are the most expensive RV toilet, but they’re eco-friendly, sanitary, and easy to use. 

Solid waste consists mainly of water. It evaporates most of it with a fan keeping the tank ventilated. The rest decomposes.

Installation is a little more complex, but the results are worth the effort.

Of course, the easiest and cheapest option is to use nature as your toilet – as long as you are comfortable doing so, discreet and above all else, responsible. 

All you’ll need is a shovel to bury your waste and some toilet paper, which you’ll need to find a bin for. But, please don’t go pooping on a beach or anywhere else other people may pass by!

Not only is it disgusting, but you’d be giving every van lifer & RVer a bad name. Just look out for a public toilet. It’s not always easy in the middle of the night, though.

Emptying a Cassette Toilet

How to empty a portable toilet

The actual process of emptying a cassette toilet is relatively straightforward. Open the hatch on the outside of your vehicle and push in on the pressure points to release it. 

Then pull up the lever to unlock it before sliding it out.

Wheel or carry it to the disposal, and then swivel the nozzle around to face away from the cassette, removing the cap. Then just press the pressure release valve, and pour out the contents. 

Once it’s empty, it’s a good idea to give it a bit of a clean.

Once that’s done, refill the chemicals if necessary and replace the cap before rotating it back around. 

Slide the cassette back into your vehicle and push the lever down to lock it into place.

Cassette Toilet Chemicals

You can use a few different chemicals for a chemical toilet, but you’ll usually just choose from blue or green in the black water tank. 

Blue is the standard chemical, but green is an alternative that’s free from Formaldehyde. 

Check your campground and RV dump station requirements, as some mandate that only green can be used.

Pink chemicals are also available, but these aren’t for the waste tank. They are additives for the flush tank that improve the fragrance of your toilet. They aren’t needed, so it’s up to you.

To do away with the need for chemicals, you can retrofit a SOG kit. It adapts your cassette toilet, so it works in a similar way to a composting travel toilet.

Cassette Toilets and Toilet Paper

toilet paper for cassette toilets

Using regular toilet paper with a chemical toilet can be a little bit risky because it’s possible to block the waste tank. 

An alternative is to buy quick-dissolving paper that’s designed to break down faster. Others people just prefer to use a separate bin next to the toilet to store used paper.

Ultimately, it’s your preference, but if you buy a bin, make sure it has a lid and that you empty it regularly. Otherwise, those odors will quickly build up. 

We use a separate bin in our onboard bathroom and use biodegradable and slightly scented dog poop bags.

In Conclusion

A cassette toilet is a good option if you can’t afford the upgrade to a composting toilet. They’re a step up from a portable toilet and a leap forward from a low-cost and less sanitary option.

The best cassette toilets are comfortable and easy to use. Find one that’s a good size for your camper, and be careful when you empty it. 

It’s not a nice job, but you’ll get used to it. Or just get your partner to do it for you every time.
