A cassette toilet is used in RVs or campers in the place of traditional, built-in toilets which empty into large waste tanks that must be pumped out at a large dump station. Cassette toilets are usually built into your RV and come with a small, portable waste tank that can be manually removed. Contents are then discarded, without the use of a pump, at either a public bathroom or a dump station. While cassette toilets do not have nearly the holding capacity as that of the traditional RV toilet, they make RV living more accessible as it eliminates the need to plan trips around dump site locations. You can simply remove the portable waste tank, which is usually equipped with wheels to make transportation easy, and empty it in an appropriate place along your travels. Cassette toilets work much like your home toilet. Freshwater from your RV's central water system to flush waste into the holding tanks with the simple push of a button. Some toilets even come with their own water tank which eliminates the need to access water that is used throughout the rest of the RV. Most toilets come with a waste level indicator so that you always know when your waste tank needs to be emptied. This makes travel planning much easier all around.
