The emptying arrangement decides the toilet, not the seat height
Portable toilets come in three arrangements, and the choice is really about what happens afterwards rather than about the seat. A bucket and liner system is a seat over a rigid pail with a bagged insert: light, cheap, no plumbing, and entirely dependent on the bags and on having somewhere to put them. A flush model carries two tanks — a fresh water tank and a waste holding tank, both quoted in liters — separated by a blade valve; it is the most familiar to use and the heaviest to carry to an emptying point. A separating design keeps liquid and solid in two containers, which is why it stays odorless without chemicals, and it asks the user to understand it. Once the type is settled, the numbers are ordinary furniture numbers. Seat height decides comfort and whether standing up is easy. The stated load rating is published for the seat and lid assembly. Waste tank capacity in liters sets how often it has to be carried, and a full tank is heavier than any listing photograph suggests. Look also for a level indicator, a vent button that stops a pressurised tank spitting, and a valve seal the maker sells as a spare part. Disposal is not an equipment question: emptying points and what may go into them are set by the site and by local rules. We compare toilet type, fresh and waste tank capacity in liters, seat height, stated load rating, valve and seal arrangement, packed dimensions, and empty weight.
Seat and lid only · fits a 5 gal / 19 l bucket · 0.7 lb · polypropylene
A seat and a lid that snap onto a five-gallon bucket you already own — 0.7 pounds, published to the hundredth of an inch, with no pail and no bags in the box.
Best for: A bucket already in the garage, and the lightest possible answer
≈ $16
15 in seat · 450–500 lb as a range · 4.8 lb · bags rated 11–13 lb of waste
The only toilet in this group that publishes its load rating as a range — 450 to 500 pounds — and the only one that rates the bags by the weight of waste they hold.
Best for: A car or a tent where the seat has to be the widest available
≈ $30
16 in seat, 12 in wide · 400 lb · fits 31.5 × 35.5 in bags · ABS, carry bag
The tallest seat in this group at sixteen inches, published for knee trouble — and the only listing here that gives the bag size it takes in inches.
Best for: A family camp where the seat height has to suit everyone
≈ $60
450 lb · 12 in seat opening · folds to 14.1 × 12.6 × 2.7 in · fits 12 gal bags
The flattest folding toilet in this group — under three inches packed — with a 450-pound rating, a phone tray, a paper holder and the bag size it takes published in gallons.
Best for: A car boot where the toilet has to disappear between trips
≈ $40
15.6 in seat · 350 lb · aluminum alloy · 2.5 lb · 12 bags and 6 gel packs
The only aluminum toilet in this group and the lightest complete one at two and a half pounds — with the lowest load rating on the shelf, 350 pounds.
Best for: A pack rather than a boot, where every pound is counted
≈ $40
Flush · 20 l detachable waste tank · 100+ flushes · double-sealed drain valve · level indicator
The only flush toilet in this group: a twenty-liter detachable waste tank, a double-sealed drain valve, a piston pump and a level indicator — and no fresh water capacity published anywhere.
Best for: A camper or a boat with an emptying point within carrying distance
≈ $100
This family belongs to the the camp kit — see everything that has to work with it.
The published type says so: flush with a tank, bag, or separating. The constraints differ entirely.
For isolating the waste tank from the bowl. Its mechanism is published and decides day-to-day comfort.
Emptying arrangements are the maker’s and depend on local rules. This site prescribes nothing.
The figure the maker publishes for the seat. This site reports it and grants no permission from it.
The published seal arrangement is what the maker provides for. Treatment products are a matter for their manual.
That depends on the published toilet type. Bag models need them continuously.
The published figure is compared against a domestic seat. Many compact models sit distinctly lower.
Packed dimensions are published separately from the deployed ones. Neither follows from the other.
Waste tank capacity decides how often the chore comes round, fresh tank capacity decides the flushes, and the seal arrangement decides whether the thing stays in the camp or goes back to the garage.
The table keeps only what four items in five declare. A half-empty column hands an advantage to whoever kept quiet.
