Gravity, hand pump or 12 V: the water has to move somehow · review
The only gravity bag in this group and the only shower here with an on-off switch at the head — twenty liters heated to 113 °F in three hours of sun, at 408 grams.
A solar shower bag of 5 gal / 20 L with a removable hose and an on-off switchable shower head.
KIPIDA states leak-proof, environmentally friendly materials heating water to 113 °F (45 °C) in 3 hours of direct sunlight, with no gas or electricity needed; a capacity of up to 5 gallons / 20 L in a compact, lightweight bag; a hose, a shower head and a water tap supplied, with a hanging hook sling for a tree or a shower tent, and an upgraded head with an easy on/off switch from low to high flow; a temperature indicator in °C and °F attached to the bag; and a 12-month warranty with a 30-day money-back guarantee.
No hose length. No fill opening. No packed size.
The feature this shelf’s introduction singles out.
Wet, stop, soap, rinse. Without a trigger, the only way to stop a gravity bag is to lift the head above the water line or kink the hose.
Twenty liters is not much water once it is running, and this is the only shower in this group that publishes a way of stopping it. The switch is also stated adjustable from low to high, so the same bag is a trickle for washing up or a full flow for a rinse.
This shelf’s buying tip, in a sentence.
Water is about a kilogram per liter, and a branch that holds an empty bag proves nothing about a full one.
Twenty liters is the largest capacity in this group, and gravity is the only thing moving it — so the bag has to be at head height before it does anything. Fill it where it hangs.
A figure with its condition attached.
Direct sunlight, by the maker’s own words, which is more than most solar claims state. Forty-five degrees is hot for a shower.
A black bag of twenty liters on an overcast day will not reach it, which is why the temperature indicator printed on the bag matters: the figure does not have to be assumed. What a solar bag cannot do is cool itself down again.
What the other four showers in this group all need.
Four of the five showers here run a 6000 mAh pump, and three of those also ship a 1500-watt immersion heater that needs a wall socket or a generator.
This one has no electrical part at all, which is why the ingress rating row on this page reads not applicable rather than not published.
KIPIDA’s instructions carry the filling and the hanging. Nothing here replaces them, and nothing on this page describes any product as safe.
The American Amazon store was listing it at about $19 at the time of writing.

Because twenty liters is not much water once it is running. This shelf's introduction names it as the single feature that makes a small tank last a whole wash: wet, stop, soap, rinse. Without a trigger the only way to stop a gravity bag is to lift the head above the water line or kink the hose. This is the only shower in this group that publishes one, and the switch is also stated adjustable from low to high — so the same bag can be a trickle for washing up or a full flow for a rinse.
About twenty kilograms, and that is this shelf's buying tip’s whole point: water is roughly a kilogram per liter, and a branch that holds an empty bag proves nothing about a full one. Twenty liters is the largest capacity in this group and it has to be lifted to head height to work at all. The practical answer most people reach is to hang it from a vehicle, a shower tent frame or a substantial branch, and to fill it in place rather than carry it full.
That is the maker’s figure and it comes with its condition attached — direct sunlight — which is more than most solar claims state. Forty-five degrees is hot for a shower; the pool-shower listings elsewhere in the catalog publish maxima of 55 and 60 °C (140 °F) on rigid tanks. A black bag of twenty liters on a cool or overcast day will not reach it, and the temperature indicator printed on the bag is there precisely so the figure does not have to be assumed. What the bag has no way of doing is cooling itself down.
Close prices, same category: comparable camping gear. We keep only the specifications all of them publish, because a column with gaps compares nothing.
