Gravity, hand pump or 12 V: the water has to move somehow · review
RISEPRO 20 litre solar bag with a temperature indicator review
The only shower in this hub with a temperature indicator printed on the bag — a gravity solar bag that tells you how warm the water got before you stand under it.
The bottom line The one bag here that tells you what it has done with the sunshine before you find out the hard way.
What this listing puts on record
A 20 litre solar shower bag, also given as 5 gallons, in black PVC stated to heat the water to 45 °C in three hours of direct sunlight. A temperature indicator marked in °C and °F is fitted to the bag. A hose, a shower head and a tap are supplied, and the maker describes swapping between the shower set and the tap as straightforward.
What kind of shower this is
A gravity bag, with no pump and nothing to charge, and one addition nothing else in this hub has.
The indicator is the feature
A temperature strip, in both scales. Every solar bag on this shelf works the same way: black material, direct sun, a wait. Only this one closes the loop by telling you what the wait achieved. On a bag that can sit out all afternoon, that is worth more than another litre of capacity.
What the listing omits
No shut-off on the head. The tap is an alternative to the shower set, not a valve within it, so the shower itself has no described way of pausing.
No hose length, no weight, no packed size. Three blanks that make it impossible to compare the bag on size with anything here.
Before you hang it
A full bag is about 20 kg of water. The temperature indicator tells you whether the water is comfortable; it says nothing about what the water is fit for, and neither does anything else on this listing.
Availability
Selling between 12 € and 14 € across the German, French and Spanish Amazon stores when this page was checked.
It also sells on the British Amazon store in the local currency, which the range above does not cover — that range counts euro stores and nothing else.
The Italian Amazon price sits more than 1.6× above the cheapest store. That gap usually means a reshipper rather than a local seller, so that listing is kept out of the range above.
Catalogued on the American Amazon store with nobody selling it: the reference is there, the offer is not.

What it does well, and where it gives way
Strengths
A temperature indicator in °C and °F is printed on the bag, which no other shower in this hub offers
Publishes a temperature and a heating time together — 45 °C in three hours of direct sun
A tap is supplied alongside the shower head, so the same bag can fill a pan or a bottle
Compromises
No shut-off on the head itself; the control described is a tap that replaces the shower set rather than working with it
No hose length, no weight and no packed size anywhere on the listing
The materials are called safe and leak-proof without naming a standard or a test behind either word

What people ask before buying
What does the temperature indicator do?
It shows the temperature of the water in the bag in both °C and °F, so you are not guessing before you stand under it. On a black bag left in direct sun for hours, that is a genuinely useful thing to read, and it is the one feature no other shower in this hub has.
Can I use it as a tap instead?
The maker states a tap is supplied alongside the shower head and that swapping between them is easy. That makes the same 20 litres usable for washing up or filling a pan. What the water is fit for is a matter for the source and the site, not for the bag.
Mains-heated electric shower · 15 litre collapsible tank · 220 V 2000 W heater · 42 °C in 15 minutes stated · warm up to 3 hours stated · 3 or 4 litres per minute · 1.8 m hose
The only shower in this hub that heats its own water — a 15 litre collapsible tank with a 220 V heater, which means mains power or a 2000 W inverter before anything happens.
Best for: A camper van or a caravan with an inverter or a hook-up, where hot water on demand is worth carrying a heater for.
Gravity solar bag · 20 litres · no pump · hand-held head on a flexible hose · carry handle · no hose length, no weight, no ingress rating
A gravity solar bag: fill 20 litres, hang it in the sun and let height do the work — with no hose length, no weight and no shower duration published anywhere.
Best for: A sunny pitch beside the car, rinsing off sand or sweat, where a hanging point is easy to find and simplicity is the point.
Rechargeable pump unit, no tank · 3 or 4 litres per minute · 4800 mAh · IPX7 · shut-off valve on the head · built-in water filter · no run time, no hose length, no weight
A pump rather than a bag, carrying the highest ingress rating in this hub at IPX7 and a shut-off valve on the head — and publishing no run time at all.
Best for: A pitch or a van with a water container on site, where a shut-off on the head and a rating that survives immersion matter more than a published run time.
