BERGER Bio Supreme 22 L flush toilet, starter set with paper and sanitary fluids review
A two-tank flush toilet sold as a starter set with paper and sanitary fluids, and the thinnest specification of the nine: two of the nine columns this hub compares are filled.
The bottom line The most complete starter set on the shelf, and the emptiest comparison sheet in the hub.
What this listing puts on record
A portable flush camping toilet stated at 22 L in its title, with a piston-pump flush, a removable waste tank, a level indicator, a swivel-out emptying spout with a vent valve, a built-in transport wheel, and a lid and seat that come off without tools — sold as a starter set with special toilet paper and matching sanitary fluids.
A set rather than a toilet
The first bullet point is a packing list, not a specification: the toilet, the paper, the fluids, everything needed to begin. Nothing else in this hub arrives with a flush chemical in the box. It is a genuine convenience, and it is also what the whole listing is built around — the four bullet points that follow describe features and comfort, and never return to a number.
22 litres, of what
The only figure on the entire page is 22 L, and it sits in the title next to the model name. A flush toilet has two tanks. Which one holds the 22 litres — or whether it is the pair of them together — is never stated, and the removable waste tank named in the title gets no volume of its own. That is the number that decides how many days pass between carries, and it is the number this listing leaves ambiguous.
The fluids are the maker’s business
Sanitary fluids and special paper come with the set. How much goes in, when, and what happens to the tank contents afterwards are questions for the maker’s instructions and for the rules of the site you are on. This page records what is supplied. It does not tell you how to use it, and it does not tell you where to empty it.

What people ask before buying
Is 22 litres the waste tank?
The listing does not say. The figure appears in the title beside the model name, and the bullet points describe a removable waste tank, a level indicator and a piston-pump flush without attaching a volume to either one. On a flush toilet the split between the two tanks is exactly what decides how often it has to be carried.
What do the sanitary fluids do?
The set includes them, and the listing goes no further than saying so. How they are used, in what quantity, and what may be done with the contents afterwards are set out in the maker's instructions and by the rules of the site. This page does not extend them.
Dry separating camp toilet set · 5 L urine canister · 38 cm seat height with the riser fitted · odour-trap plug, hemp litter, two 10 L compostable bags and six clips · no water or chemicals
A dry separating toilet sold as a set rather than as an object: the 38 cm seat height it publishes is the height with the supplied riser fitted, and the toilet on its own is never given one.
Best for: A van conversion already built around the maker's box system, where the toilet has to clip to what is there.
Folding bag camp toilet · leather-faced seat on an MDF core · 42 cm seat height stated · 200 kg stated · folds to 8 cm · hinged lid and closing seat ring · biodegradable bags supplied
The highest seat height of the nine at 42 cm, on a folding bag toilet with a leather-faced seat over an MDF core — and no mass and no capacity published anywhere on the page.
Best for: Knees that will not thank you for a 30 cm seat, where the toilet travels by car rather than on a back.
Bucket camp toilet · 19 L single container · 38 cm seat height stated · 120 kg stated · moulded pouring recess · seven colours · no mass or packed size published
The simplest toilet of the nine: one 19-litre bucket under a seat and lid, a 38 cm seat height and a moulded recess to pour it out of — no tanks, no valve, no published mass.
Best for: A festival or an allotment pitch where the toilet lives in a car boot and the seat height is the only figure that has to be right.
