Some points to consider when buying a portable toilet for camping/recreation:

Portable toilets are comprised of two separate tanks as well as a pump for flushing. The two tanks consist of a flush tank and a holding tank. The flush tank, as the name suggests, is used to flush the toilet. It is filled with water as well as a flush tank additive. This tank is always the top tank in portable toilets.

The holding tank stores the waste in the bottom of the toilet and houses holding tank additive mixed with water. This is the tank which is emptied when the toilet is full.


Portable toilets come in a range of shapes and sizes to suit different needs. If it is a toilet for a couple, a 10 – 12 litre capacity holding tank would be suitable. If the toilet is for a family however, the larger size toilets with holding tanks up to 21 litres would be more suitable. These larger units also bring the seat higher off the ground and feel more like your toilet at home. A good point to remember when choosing a toilet is; larger capacity= fewer empties.


As toilets are housing human waste, toilet additives are required to keep it both sanitary and to reduce odours. Two different types of liquid are used for this purpose.

Top Tank Liquid: This pink fluid is mixed with water and placed in the top tank. It provides a fragrant smell and puts a non stick coating on the bowl when flushed.
Bottom Tank Liquid: There are two different types of bottom tank fluid which offer different levels of speed in breaking down the waste.

Green Holding Tank Fluid: Lasting between three and four days, this fluid biologically breaks down waste. For this reason it is regarded as the more environmentally friendly option.
Blue Holding Tank Fluid: Lasting between four and five days, it has a fresh fragrant scent but should always be emptied into toilets or sewerage systems.


As portable toilets do not have advanced plumbing systems, special toilet paper must be used to prevent clogging. Aqua soft toilet paper decomposes quickly in the waste tank and avoids clogging to ensure emptying your toilet is quick and easy.


All Porta Potti toilets are quick and easy to empty. With the toilet additives working efficiently to break down anything in the bottom tank, odours and unpleasentness is kept to a minimum.
It is imperative to check local regulations to find the most appropiate place to empty the contents of a portable toilet.


Select a toilet with a gauge for the added convenience of knowing exactly when the next empty is required.
Make sure you keep spare toilet additives on hand so you never get caught out in the outdoors.
Always read the operating instructions of your particular toilet before you use it for the first time.
