A solar camping shower turns nothing but sunlight into warm water, no fuel, no batteries, no moving parts. The best one for you depends on how much pressure you want and how reliably sunny your trips are.
Our quick picks
The picks
Best solar shower overall: Advanced Elements Summer Shower
The Advanced Elements Summer Shower is the archetypal solar camp shower done right: a 5-gallon bag with a four-layer construction (a clear top panel over a black absorber layer) that heats noticeably faster than single-layer black bags. Fill it, lay it flat in direct sun for 2–3 hours, hang it from a branch or shower stand, and gravity does the rest. Manufacturer specs cite water reaching comfortable shower temperatures (80–110°F depending on conditions) in about 3 hours of full sun.
Flow is gravity-only, so expect a gentle stream rather than a spray. Five gallons covers one thorough wash-and-rinse or two quick rinses if you close the valve between lathers. A side pocket holds soap, a small mirror mounts on the face of the bag, and the whole thing rolls to the size of a paperback. At roughly $30–$45 it is the cheapest reliable hot water in camping.
Best for: Car campers and weekend campers in sunny climates who want warm water with zero fuel, zero batteries, and near-zero cost.
Best solar shower with real pressure: NEMO Helio LX
The one thing a hanging solar bag cannot give you is pressure. The NEMO Helio LX fixes that: a 22-liter (about 5.8-gallon) soft tank lies flat in the sun to heat like any solar bag, but a foot pump pressurizes the system to roughly 10 PSI, which produces an actual shower spray strong enough to rinse shampoo or hose mud off gear. At moderate flow the tank delivers close to 7 minutes of pressurized water, and the valve holds pressure between lathers so nothing is wasted.
Because it sits on the ground rather than hanging, you skip the hunt for a sturdy branch, and the whole system packs down to a flat disc. At $175–$200 it costs several solar bags' worth, but it is the only pick here that combines sun-heated water with genuine pressure and no fuel or electricity.
Best for: Car campers and overlanders who want solar heat plus real spray pressure and are willing to pay for it.
When solar is not enough: battery pick
Solar showers have one honest weakness: they need sun. The Ivation Portable Outdoor Shower sidesteps the weather entirely. Drop its USB-rechargeable pump into any bucket, jug, or pot of water you have warmed on a camp stove, and it pushes a steady flow (around 1.5 liters per minute) through a real showerhead. Owner reports put runtime at roughly 2–2.5 hours per charge, which covers many showers.
The Ivation does not heat water itself, which is exactly why it pairs so well with a solar bag: heat water in the bag on sunny days, heat it on the stove when clouds roll in, and shower the same way either time. As a standalone buy it is also the cheapest path to a pressurized camp shower.
Best for: Campers in cloud-prone regions, and anyone who wants a pressurized shower from stove-heated water when the sun does not cooperate.
When solar is not enough: on-demand hot water
The Camplux AY132 abandons the sun altogether. It is a propane-fired tankless water heater that produces hot water on demand at up to 1.32 gallons per minute, with output temperatures of 100–117°F depending on flow setting and inlet temperature. Connect a standard 1-lb propane canister, feed it water from a gravity tank or a 12V pump in a jug, and you have unlimited hot showers with no waiting and no weather dependence.
The tradeoff is bulk and setup: heater, propane, water source, pump, and hose. That is a lot of system for a solo weekend, but for group camps and overlanders who shower daily, the unlimited supply is worth the assembly.
Best for: Groups and overlanders who burn through hot water and would rather carry propane than wait on the sun.

How solar showers actually heat water
Every solar shower works on the same principle: a dark surface absorbs sunlight and converts it to heat, and the water inside acts as a thermal mass that holds it. A black 5-gallon bag in direct summer sun typically reaches 80–100°F in 2–3 hours; thin cloud cover stretches that to 4 hours or more, and heavy overcast can cut solar input by 80 percent. For the full physics, heating benchmarks, and positioning tricks, see our explainer on how solar camping showers work.
Two positioning moves matter more than anything else. First, angle the bag so its flat face points at the sun: flat on the ground at midday, propped against a rock or tree when the sun is low. Second, put it on a dark surface (a dark tarp, a dark rock, a car hood) so heat reflects back into the water instead of soaking into grass or sand.
Capacity math: gallons per shower
A disciplined camp shower (wet down, close the valve, lather, rinse) uses roughly 1.5–2 gallons per person. That means:
- A 5-gallon bag like the Advanced Elements covers one thorough shower or two quick rinses.
- The Helio LX's 22 liters (5.8 gallons) covers one long shower or two disciplined ones.
- For a family of four showering daily, plan on 6–8 gallons per day, which points toward refilling a bag twice or stepping up to the propane system.
Water weighs about 8.3 lbs per gallon, so a full 5-gallon bag is over 40 lbs. Fill it near where it will hang or lie, not back at the spigot.
Cold weather and cloudy climates: honest limits
Below roughly 40°F ambient, a solar bag may never reach comfortable shower temperature even in full sun, because heat loss to the air offsets solar gain. Shoulder-season campers and anyone headed somewhere reliably overcast should treat solar as a bonus, not the plan, and carry a backup: stove-heated water with the Ivation pump, or the Camplux if the group justifies it.
How we picked
Every pick is rated on the Kit Score: we aggregate manufacturer specs, verified owner reviews from REI, Amazon, and outdoor forums, and cross-reference gear testers who published measurable results. No invented figures, and no claims of hands-on lab testing. These four also anchor our broader roundup of the best portable camping showers, which compares them against the full field.
Frequently asked questions
How long does a solar camping shower take to heat up?
In full direct sun on a warm day, a 5-gallon black bag reaches 80–100°F in roughly 2–3 hours. Hazy sun or cool air stretches that to 4 hours or more, and heavy overcast may leave you with lukewarm water at best. Laying the bag on a dark surface and angling it toward the sun measurably shortens the wait.
How many showers do you get from a 5-gallon solar shower?
One thorough shower or two quick rinses. A conservative wet-lather-rinse routine with the valve closed between steps uses about 1.5–2 gallons per person. Two people sharing a bag should plan to refill and reheat for the second full shower, or split the bag as two short rinses.
Do solar showers work on cloudy days?
Poorly. Thin cloud cover cuts solar input by 20–50 percent, and heavy overcast by 80 percent or more, so expect lukewarm water (70–80°F) after a full afternoon. If your trips skew cloudy, pair the bag with a battery pump like the Ivation and heat water on your stove, or skip solar for a propane on-demand heater.
Is a solar shower bag or a pressure shower better?
A hanging bag is cheaper, lighter, and simpler, but delivers a gentle gravity stream. A pressurized system like the NEMO Helio LX heats the same way in the sun but adds a foot pump for roughly 10 PSI of real spray, which rinses hair and gear far better. If you shower on most trips, the pressure upgrade is the one most campers say they would pay for again.
Can you drink the water from a solar shower?
No. Shower bags are not rated as potable water containers, and warm water accelerates off-gassing from any polymer bag material. Keep drinking water in containers rated for it and use the solar bag for washing only.
A solar shower is the cheapest comfort upgrade in car camping: $40 and a sunny afternoon buy you a warm rinse every night. Browse more camp gear picks or read about how we research and rate gear.
