Benefits Of A Cassette Toilet
While an ordinary bucket toilet will do the job, a portable cassette toilet comes with a multitude of added benefits. The biggest selling point is lack of smell. A chemical reservoir breaks down waste and hides the odor under a drain valve.
Chemical toilets are also familiar to use. They have a pump flush that doesn’t require you to separate liquid from solid waste. In the middle of the night, this is a convenient feature that also requires less action on your part.
Fortunately, a cassette toilet doesn’t need to be cleaned as frequently as a bucket toilet. The chemical tanks can go more than a week without emptying. This gives you more freedom to travel without having to look for a waste station.
How Does A Cassette Toilet Work?
A cassette toilet looks and operates much like your home toilet. To set up, you simply pour fresh water into the upper tank. A chemical solution or disinfectant goes into the wastewater tank. Once it’s ready to go there is very little ongoing maintenance that will have to be performed.
A pump flush uses fresh water to wash waste down into the chemically treated reservoir. The chemical reservoir breaks down waste to reduces smell. To empty a cassette toilet, the wastewater tank can be removed from the upper section with a lever. It can then be emptied into an RV dump station, marina, or standard toilet.
How To Dump A Cassette Toilet
The SerenLife outdoor portable toilet is one of the largest waste water tank on our list at 5.3-gallons. This gives the product roughly 50 flushes in-between cleanings. The exterior measures in at approximately 16.5in tall, 13in wide, and 16in deep.
This is a manual flush toilet that does have an indicator when it’s getting full. That means no batteries to upkeep and no guessing overfill. A 3.5-gallon clean water reservoir feeds the piston pump flush.
This product is sturdy and closes tight with a double-sealed drain valve. That makes it an ideal portable toilet to use as secondary seating within a van. The wastewater tank has a rotating pour spout that makes the dumping process clean and easy.
It’s difficult to find negative reviews on the SerenLife. The piston pump flush is very powerful and will do a great job of washing down waste. If pushed too aggressively there may be some splash back.
Thetford is a popular travel brand with two porta potties on our list. The Thetford 260B is the smallest portable toilet on our list with a 2.6-gallon waste water tank. This makes it ideal for someone who does not want to lift a lot of weight or has less space inside their van. The exterior dimensions of the toilet are 14in tall, 13.4 long and 15in wide giving it a much squattier appearance.
A manual bellows flush pump means less parts to break and ease of use. It holds 2.6-gallons of clean water and does not require batteries. A single sealed valve keeps the odors low.
Because the waste water tank is so small, you can expect about 27 flushes between cleaning. As a con, the product does not come with a waste level indicator. You will have to keep track of this so the bottom tank does not overfill. Finally, there is no carry handle on the waste reservoir. It will have to be kept level during transportation. Luckily, the tank is small so it should not be too difficult to carry.
The Camco standard has been around for a long time and is the most reviewed item on our lineup. It has the same size waste water tank as the SereneLife (5.3-gallons) but is slightly shorter and wider measuring in at 15.5in tall, 14in wide, and 16in deep.
Many favorable features are present in the Camco. It’s size and sturdiness make it ideal for long trips and extra seating. The bellow pump gives a controlled flush without extra parts. It also has a robust sealed valve to lock in odors.
This portable toilet is measureable with the SereneLife but there are a few key differences. No waste water level indicator is present on the Camco Model. There is no rotating pour spout.
Because this product lacks a waste level indicator, it will be more difficult to tell when it is full. The pour spout is simply a cap on the end of the reservoir which means you’ll have to be a little more careful when dumping.
Similar to what we’ve seen in our refrigerator reviews, Dometic consistently delivers feature packed products. Of course, these benefits come with a price. The Dometic portable toilet is the most expensive in our review.
This portable toilet is constructed with ABS and high-density polyetheline so you can sit, stand or climb on it. Besides the great looks, the Dometic 5-gallon portable toilet comes with stainless steel hold downs. This is perfect for driving around and securing the toilet firmly to your vehicle. Handles on both the top and bottom reservoirs make it easy to move around as well.
The Dometic toilet comes with a push-button pressurized flush. It will make you feel more at home, but of course comes with more parts and the potential to malfunction. The button flush does need to be occasionally pressurized to work seamlessly.
One of the biggest complaints we’ve seen with this toilet is the small seat. Even though the external dimensions fall in the range of other toilets (13.5” x 15.5” x 16.5”) the seat is significantly smaller.
Based on the Zimmer comfort portable reviews, this is all-around a good toilet to own. It is reasonably priced and hits most of the boxes checked. Measuring in at 16.5” x 16” x 14.5” it is on the shorter side of toilets with the 5-gallon tank. Combined with the large waste reservoir this makes it a great long-term travel choice.
This cassette toilets comes with a bellows flush pump which is one of the best rated we’ve come across. A bellows flush has with minimal parts making it a reliable pump. There is also a sturdy handle built right into the bottom reservoir.
As a con, there is no pour spout and no waste level indicator on the bottom tank. This means you will need to do a little guess work when it comes to determining the fill level. Fortunately, instead of a pour spout there is a very large screw cap. This should make it relatively easy to clean out waste.
