Whether you’re only in it for the annual road trip or you’re a camper at heart, you’ll surely be familiar with both the fun times and mishaps when it comes to staying in an RV or pop up camper. Even veteran campers have things that they wished they knew when they were just starting out on living the van life, such as having the proper water source, cassette toilet, shower area, and being sustainable, among many others.

In this blog post, we’ll delve into what they are first. Knowing which one would suit your vehicle and lifestyle the best will bring huge changes to your camping life! Having a portable toilet right from the start of living in a van will improve both sanitation and comfortability, which will help you adjust to the lifestyle.

Here’s the extensive guide on the best cassette toilets and shower combos that can fit perfectly into an RV or whatever purpose you may wish for – make sure to check out the Thetford options!

What is it?

Cassette toilets are a common fixture that you’ll see in European RVs, a permanent toilet with a portable holding tank that makes camping life a lot easier. Bear in mind to not confuse them with portable ones. With cassette toilets, the toilet is permanently attached to the RV, and only the holding tank is removable or portable. On the other hand, with portable toilets, the whole system (toilet and holding/waste tank) is removable/portable, which is a good feature for when you prefer to take a dump outside.

Nowadays, even in America, a lot of RVs for sale have these in them compared to the traditional RV toilets, which brought a surge of popularity for these products. Numerous manufacturers that were solely based in Europe before are now venturing into more countries due to this. Check out the table below for your cassette toilet shower combo, and cassette toilet needs for your RV or pop up camper, with Thetford being on that list!

Why is it the best pick?

A lot of campers prefer the cassette toilet over the usual options because of its portable holding tank feature. With traditional options, you’d have to drive to a place with a dump station before you can clean it out. This can be quite a hassle when you’re camping at a site with no nearby dump station in sight. On the other hand, with this option, you can camp out anywhere regardless of the presence of a dump station. Since it has a portable feature, if there are no available dump stations nearby, you can simply remove it, go to the nearest public restroom, and dump the contents of the tank there. This way, you no longer have to worry about prioritizing the availability of dump stations when picking for a camping site.

Also, having an option to buy a replacement for the portable waste tank will save money in the long run. This way, if it gets damaged, you only need to buy a new tank of the same type—you don’t have to change the toilet, too!

Furthermore, they preserve the smell of clean air inside your RV with its chemical reservoir that breaks down waste and prevents the odor from wafting out from under the drain valve. Lastly, there is no need to separate liquid and solid wastes when you’re using chemical cassette toilets, which makes everything more convenient for you.

How does it work

They are very easy to use and maintain. The way it works is very similar to how a home toilet would operate. In a nutshell, here’s how it works: a compact bowl is installed permanently in the RV over a removable waste tank, the waste is flushed directly into the tank after flushing, and you must remove it when it’s full.

Components
Toilet Pump flush Portable tank

In general, all models have three main components, namely, the toilet, flush/water source, and the portable waste tank.

  • Toilet
    • As previously mentioned, it is permanently fixed. They have a control handle that enables you to open and close the valve between the toilet and the waste tank underneath. Some have a toilet that turns 180 degrees to allow maximized space usage, while some can only rotate at a 90-degree angle.
  • Pump flush
    • The flush makes use of fresh water to direct the waste down into the tank. For most models, the water is usually sourced from the RV’s central reservoir, while some have their own holding tank.
  • Portable waste tank
    • It is usually accessible from a door located outside, on the driver’s side, of the RV. This makes retrieval easy when you need to dump the contents.
    • It is a chemically treated reservoir; a chemical solution goes into this tank, which breaks down the waste and prevents bad smells from permeating through the RV.

To use the unit, all you need to do is make sure the water source is connected to the RV’s central water tank or if the model has its own water tank, make sure it’s filled properly. Check if the chemical solution is in the wastewater reservoir. Once everything is set up, you can go ahead and use the toilet. Just make sure that the valve is open prior to using it, so that the waste can travel to the reservoir after use. Once you’re done and you’ve already flushed, close the valve and lid.

Monitor the indicator of the waste reservoir regularly; check if it’s nearly full. It is always better to empty it out before its capacity is maxed out to ensure a fresh-smelling vehicle. Also, always monitor the availability of fresh water for the flush, whether it’s your RV’s central water tank or the water tank.

How often should you empty it?

With the help of the chemical treatment within the water reservoir, you won’t need to empty it out as often compared to bucket toilets that usually require daily cleaning. It is recommended to empty out and clean a cassette toilet every 2-3 days to retain a fresh and clean environment within your RV. The disinfectants that go together with the chemical toilet are helpful when cleaning the toilet. Simply mix water and a liquid bio detergent so that the remaining wastes in the tank can be disposed of in liquid form, which makes cleaning and maintenance easier. Water and ammonia or distilled white vinegar can also be used to keep the tank and area smelling fresh.

Also, it is very important to carefully read and follow the user manual’s instructions. Do the indicated maintenance check and cleaning on the valve blade and seal to prevent any mishap from happening while you’re on the road.

Size, Weight & Capacity

Ensure that the model that you’re buying can easily fit without any repercussions. Consider the working area that you’ll be left with when it is installed. If you want something that can double as an extra seating, look for tall chemical toilets that will be comfortable to sit on. If you’re only looking for an option that you’d only use solely during relieving yourselves, then it’s better to opt for shorter models to save up space.

Also, it’s important to take note of the weight that the whole system will be when it is full, and make sure that you can handle the weight when it’s time to carry it to the dump station. If you bought a 5-gallon chemical toilet, make sure that you can carry it when it’s full, which can weigh up to 30-40 lbs.

For the capacity, consider the number of people that it will accommodate and your access to dump stations. If you’re only travelling by yourself and will be camping in areas with dumping stations, a 3-gallon cassette toilet may be the perfect choice for you. But if you have less access to dumping stations or you’re traveling with one or two more companions, then opt for a toilet that has a bigger capacity.

Flush

For flushes, choose your preferred flushed type. Some have a pump flush, while some have a battery-powered flush. Both are useful, but some people prefer pump flush better because you won’t need batteries for it. Another thing to consider is the flush nozzle type. It’s better to pick a three-way nozzle because it keeps everything tidier after every flush compared to a single sprout flush.

Indicator

Not all models have colored indicators that will tell you when the tank is nearly full (or already full). It’s better to opt for one that has one, so that you can plan ahead and make your way towards the nearest public restroom or dumping station. This also makes cleaning and maintenance easier because ones with no indicators can be pretty difficult to monitor, and sometimes leaks happen when you’re not paying close attention to the capacity.

Lid lock and sealed valve

Always pick one that has a tight lid lock and valve between the upper and lower tanks to prevent splashes and leaks and to avoid bad odours. Sometimes, pressure can build up in the waste tank, and opening the valve can cause some splashes. So, it’s better to open the valve first while the lid is tightly locked, to make sure that you won’t get splashed by wastewater.

Waste tank handle, wheels, and emptying spout

Toilets with a large capacity can become very heavy when full, as mentioned earlier. Make sure to pick a brand that offers carry handles for easier maneuvering of the tank when it’s time to clear it out. Some models even have extendable handles and wheels, which is a great pick for heavy waste tanks because you can carry them like luggage. Also, look for a model that has an emptying spout, so you can easily pour out the liquid waste accumulated in the tank.
