Variations in Canal Boat Cassette Toilets
Many older boats started out with the trusty cassette camping toilet. With the growth of the leisure industry and overlapping motor home and caravan markets, the choice for boaters is now pretty sophisticated.
Very basic cassette toilets have a separate reservoir tank below the bowl for collecting waste. Flushing fluid is contained in a reservoir around the bowl and flush is activated by either pushing on a bellows type button or twisting a lever.
The reservoir is separated from the bowl for emptying. These basic units are self contained, require no plumbing, very little space and are fully portable.
The other end of the spectrum are the fully plumbed in electric flush units that can even be specified with ceramic bowls for easy clean and a “homely” feel.
Installation of even the most sophisticated units in this class is simple, requiring a water supply from the on-board pump and a 12VDC feed of the appropriate size cable to prevent volt drop. They can be retrospectively fitted with relative ease but it is better to plan the system so services can be laid in during the first fix.
The majority of these units will have cassette access to the rear, being designed for caravans and motor homes where an access door can be externally mounted. This is the principle consideration when planning the position of the toilet.
Make it easy for yourself if possible and have the back of the toilet mounted against a side wall or into a corridor. The standard 17/19 litre capacity holding tank of the most popular units can be removed out into most narrowboat walkways. With wider canal craft this is obviously not an issue, although do plan for walkways to accomodate cassette removal. A neat door can be used to cover the access hole. Alternatively use the access to a vanity cupboard.

Don’t worry too much about the position of the bowl, good quality units are available where the bowl can swivel round on the fixed base by 180’. Check individual toilets from suppliers in our Specialist Products
