The best Solar showers, compared.
Top pick: RISEPRO 20 L black – Highest score among listings with their own review sample, 87, at about £8.90, with 4.1 from 3,094 reviews. Best value: RISEPRO 20 L green – Lowest single-bag price among those listings, about £7.40, with a card score of 83 and 3.8 from 5,154 reviews. Updated October 2026.
A solar shower for a UK pitch is a dark PVC bag you fill, leave in direct sun, then hang so gravity feeds a short hose. It is a camping rinse, not a roof solar-thermal collector, and not a battery pump. People use one for a tent, a van, a bathroom stopgap, or a slow boot or dog rinse, and not as a drinking-water store. You judge it by the seal, the hose and the hang. The outlet thread has to match the tap or the cap. A kinked hose will not flow. A full 20 litre bag is about 20 kilograms. Flow is gravity only, and a hose of about 25 inches is short. A 40 litre title means two 20 litre bags. Heat lines of about 40°C or 45°C in three hours are seller claims. A listing can print two temperatures that do not match. Use a temperature strip if one is fitted, and test the water on your wrist. There is no thermostatic mixer.

Question 1 of 2
How many bags do you need?
RISEPRO OW-C1004 is the black 20 litre bag at about £8.90 on amazon.co.uk, with 4.1 out of 5 from 3,094 reviews and rank 7 in Camping Showers. The listing claims a 3-hour heat to 113°C (45°C), which is an internal contradiction, plus a °C/°F strip and a 25 inch hose. UK reviews praise festival washes and sun-warmed water, and they criticise a kinked hose, short reach, weak flow unless the bag is high, and a switch or head that comes off. The score uses stars and review volume, not a heat test. The card score is 87, the highest among listings with their own review sample, so this is the top pick.
Pros
Cons
Best for: A sunny festival or a short bathroom repair if you can hang a full 20 litre bag.
Less suitable: Anyone who needs mains pressure, a long hose, or a guaranteed temperature in British cloud.
Specifications
Common questions
Does this solar shower bag include a shower head?
Yes. The listing includes a 25 inch hose, a shower head and a water tap, and says you can change between the shower set and the tap.
What heat does the listing claim?
The bullets say black PVC heats water to 113°C (45°C) in 3 hours of direct sunlight. Those two temperatures are both printed. A temperature strip in °C and °F is on the bag. Treat that line as a seller claim, and test the water on your wrist.
What do UK reviews repeat?
Buyers use it at festivals and as a temporary shower, and say it warms in the sun if it is laid out. They also say the hose arrives kinked, the bag must hang high, and the head or switch can come off.
The green RISEPRO FBA_K8 is about £7.40 on amazon.co.uk, the lowest single-bag price in this set, with 3.8 out of 5 from 5,154 reviews. It is a 20 litre PVC solar bag with an on/off head and a temperature strip. The heat line prints 113°C and 45°C together. Empty weight is printed as both 422 g and 458.13 g. UK reviews say it warms on a bonnet or dashboard and works on a van roof if you do not fill it full, and they report a kinked hose, a fragile head and at least one split bag. The 5,154 count matches the black listing B0B41KPJ3K, so it is not a second independent sample. The card score is 83. That lowest single-bag price, among listings with their own review sample, is why it is the best value.
Pros
Cons
Best for: A low-budget sunny pitch or van roof where a gentle gravity rinse is enough.
Less suitable: Buyers who need a stated hose length, a carry bag in the spec, or a bag that has already survived a full fill in reviews.
Specifications
Common questions
Does the green RISEPRO bag heat the water itself?
The listing says PVC heats water to 113°C (45°C) in 3 hours of direct sun, and a °C/°F strip is attached. UK reviews describe about 30°C after 4 to 5 hours on a dashboard, or about 6 hours clear-side-up on a bonnet. There is no battery. Treat the three-hour line as a seller claim.
Is a storage bag in the box?
The bullets do not list a storage bag. One UK review says a carry bag is still needed. The included-components line prints only 1.
What fails in UK reviews?
A kinked hose, a brittle head, an on/off switch that lasted two days, a filler-neck leak when the bag lay flat, and one unit whose cover sheet came off before a hole opened at half full.
This black 20 litre listing is about £8.40, a pound above the green RISEPRO, and the brand line says RISEPRO while the bullets say URPRO. The manufacturer line says ONE WORLD COMPANY. Bullets add a balance tube, boom and rope, a temperature strip and the same 113°C (45°C) in 3 hours line. The saved UK reviews, the 5,154 count and rank 10 in Camping Showers are the same as B01L3OUT4I, including a green cover that fell off. Use the bullet hardware as the listing difference, and do not treat the star line as a second sample of this black bag. The card score is 83. It takes no award, because the review block is shared and the price is higher than the green bag.
Pros
Cons
Best for: Only if you specifically want the boom-and-rope bullet and you accept the shared review block.
Less suitable: Anyone comparing star ratings as if this were a separate 5,154-review product.
Specifications
Common questions
Is the brand RISEPRO or URPRO?
The specification brand line says RISEPRO and the manufacturer line says ONE WORLD COMPANY. The bullets say URPRO. Both strings are on the same amazon.co.uk listing.
What hanging parts are listed?
The bullets name a PVC balance tube, a boom and a rope so the bag can hang in a tent or from a branch. A hose length is not printed.
Can the 5,154 reviews be read as a separate test of this black bag?
No. The saved review text, the 3.8 score, the 5,154 count and the best-seller rank match the green RISEPRO listing B01L3OUT4I, and one review mentions a green cover sheet. Count that pool once.
TRIXES MM54 is the dearest set here at about £12.99 for two black 20 litre PVC bags, with 3.8 out of 5 from 392 reviews. Each bag is listed with a hook, rope, support bar, flexible hose and a shower head that is also the on/off valve. The heat claim is around 40°C in direct sun, with no hour count and no temperature strip. The listing says not for drinking water. Among 21 UK reviews, sunshine heating is praised and leaks, a snapped handle, one-season degradation and a weak outlet are the repeated faults. Package weight is 610 g for the parcel, not the weight of water. The card score is 79. This is the listing, not a workshop test.
Pros
Cons
Best for: A couple or a Guide camp that wants two bags and will pressure-test them before the trip.
Less suitable: Drinking-water storage, or a buyer who wants a printed heat-up time and a temperature strip.
Specifications
Common questions
Is this one 40 litre bag?
No. The title says 40 L as two bags of 20 L. Each bag is up to 5 gallons or 20 litres, and the set is two bags.
Can you store drinking water in it?
The listing says it is not suitable for drinking-water storage. Do not treat the other bags in this set as drinking-water carriers either if their listings do not say so.
What do UK reviews report?
Some buyers got warm water in sunshine and used a bag at Guide camp. Others report leaks at the bag or hose, a handle that snapped, stretch when hung, a dribble from a small outlet, and one heatwave in which the water did not heat as stated.
LFSEMINI is a two-pack of 20 litre PVC solar bags at about £7.99 on amazon.co.uk, with 3.5 out of 5 from 155 reviews and a much lower camping-shower rank than the RISEPRO singles. The bullets claim 40°C in 3 hours, an on/off switch and a hook sling, and they do not list a temperature strip. Across 38 UK reviews the repeated fault is a tap or cap thread that does not fit, plus slow flow, a kinked hose and a plastic smell. Some buyers did get warm water after about four hours when the parts went on. The low pack price is not treated as best value because several buyers could not use a bag out of the box. The card score is 71. This is the listing, not a workshop test.
Pros
Cons
Best for: A buyer who will test both threads with water before a trip and can return a mismatch.
Less suitable: A festival departure the same day, if you need both bags to seal without tape.
Specifications
Common questions
How many bags are in the pack?
Two. Each is listed at 5 gallons or 20 litres. The shelf price on the saved line is about £7.99 for the pack, not per bag.
Do the taps fit?
The listing does not give a thread size. Several UK reviews say the supplied tap or cap thread does not match the outlet, cross-threads, or will not go on, on one or both bags.
Does the listing include a temperature strip?
No temperature strip is in the specification or the bullets. The heat claim is 40°C in 3 hours of direct sun. Treat that as a seller claim.
Five amazon.co.uk solar shower bags are on this page. There is no separate methodology sheet and no laboratory heat test. Each card score is the figure already printed for that listing: the amazon.co.uk star rating divided by 5, multiplied by 70, plus the base-10 log of the review count multiplied by 10 and capped at 30. The two parts are added and then rounded. The top pick is the highest score among listings with their own review sample, the black RISEPRO 20 litre bag at 87. Best value is the lowest single-bag price among those listings, the green RISEPRO at about £7.40, with a card score of 83. The black listing whose bullets say URPRO shares the saved review text, the 3.8 score and the 5,154 count with the green bag, so it takes no badge. Prices and stars are the saved amazon.co.uk lines.
Amazon star line
70%Star points are the amazon.co.uk rating divided by 5, then multiplied by 70. A 4.1 line is 57.4 points before volume is added. A 3.8 line is 53.2. A 3.5 line is 49. This is the listing average, not a laboratory score.
Review volume
30%Volume points are the base-10 log of the amazon.co.uk review count, multiplied by 10, and capped at 30. The card score adds the star points and the volume points, then rounds. A shared review block is counted once. The listing whose bullets say URPRO uses the same saved review text as the green bag, so it adds no second sample.
A solar shower bag is a 20 litre PVC bladder you leave in the sun and hang for a gravity rinse. Read the thread, the hose and the heat claim before the star line. Prices and stars below are the saved amazon.co.uk lines for these five listings, not a laboratory test.
A solar shower, among the products kept for a camping or festival rinse, is a dark PVC bag you fill with fresh water, leave in direct sun, then hang so gravity feeds a short hose. UK shoppers are not buying a roof solar-thermal system. The government technology note treats that as a collector and a hot-water cylinder. They are also not buying a USB bucket pump.
One heat line prints 113°C and 45°C together. Those figures do not both describe a shower. Treat the line as a seller claim, and test the water on your wrist before it touches skin.
A full 20 litre bag is about 20 kilograms. Flow is gravity only. UK reviews sit, kneel, or use a van roof. A 25 inch hose is short. Do not expect mains pressure.
Two listings share one saved block of 5,154 reviews, the same 3.8 score and the same rank line. Adding that figure twice invents a second sample. The listing that shares the block takes no award.
The first check is whether the bag is actually sun-heated. A USB pump whose listing says there is no heating function is a different product, and this page does not score those pumps. Heat lines that promise about 40°C or 45°C in about three hours are seller claims. One listing prints 113°C and 45°C together. Do not publish 113°C as a measured temperature, and do not claim a bag reaches 45°C in three hours of British weather.
Every bag kept here is 20 litres. A full bag is about 20 kilograms, so the hang has to hold that weight. A title that says 40 litres means two 20 litre bags. Flow is gravity only. UK reviews sit, kneel, or use a van roof, and a stated hose of 25 inches is short. The outlet thread has to match the tap or the cap. Mismatched threads are the repeated complaint on one twin pack, which is why a low pack price is not automatically the best value. Straighten a kinked hose before the trip.
Three typical situations, each with a recommendation from this comparison.
You can hang a full bag from a van, a sound branch or a shower tent and you want a short rinse. The black RISEPRO 20 litre bag is the top pick at about £8.90, score 87, with 4.1 from 3,094 reviews. UK reviews praise festival washes and also report a kinked 25 inch hose. It warms only in the sun.
You want the lowest single-bag price, and a gentle gravity rinse in the sun is enough. The green RISEPRO 20 litre bag is the best value at about £7.40, score 83, with 3.8 from 5,154 reviews. UK reviews report sun-warmed water on a vehicle, and also a kinked hose and a fragile head. A full 20 litres is hard to lift.
You want two bags, with a hook, rope and support bar listed, and you will pressure-test them before the trip. The TRIXES set is about £12.99, score 79, with 3.8 from 392 reviews. The listing says the bags are not for drinking-water storage. UK reviews include leaks and a snapped handle.
The top pick is the black RISEPRO 20 litre bag at about £8.90. The score is 87, from 4.1 and 3,094 amazon.co.uk reviews, the highest among listings with their own review sample. UK reviews praise festival washes and sun-warmed water. The hose is 25 inches and reviews say it arrives kinked. The heat line prints 113°C and 45°C together, so that line is not a measured result. The best value is the green RISEPRO 20 litre bag at about £7.40, score 83, with 3.8 from 5,154 reviews. It is the lowest single-bag price among listings with an independent review sample. The same 5,154-review block also appears on the black listing whose bullets say URPRO, so that count is not a second sample. The twin pack at about £7.99 is not the best value: UK reviews repeat a tap thread that does not fit. Neither score is a laboratory test.
