A solar shower is a water bag you leave in the sun. The sun warms it, and gravity does the rest. It’s one of the cheapest upgrades in camping, and it’s also easy to get wrong.
The main choice is between a gravity bag and a pressurized shower. Here’s one pick for each job.
| Pick | Type | Capacity | Best For |
|---|---|---|---|
| Advanced Elements 5-Gallon Summer Shower | Gravity solar bag | 5 gallons | Car camping and families |
| Sea to Summit Pocket Shower | Ultralight gravity bag | 2.6 gallons | Backpacking |
| NEMO Helio LX | Pressurized, foot pump | 5.8 gallons | Real water pressure |
How a Solar Shower Works, and Where It Falls Short
Most solar showers are black bags. In direct sun, the better ones warm five gallons to about 110°F in under three hours. Warm is the right word. You won’t get a hot shower.
On a cloudy day, the sun won’t do the job. You can pour in hot water from a stove, which every bag here allows.
Pressure is the other catch. A gravity bag only has the height you hang it from, so the flow is a gentle stream. One test measured about 0.9 liters per minute for the Advanced Elements.
Water also weighs about 8.3 pounds a gallon, so a full 5-gallon bag is roughly 42 pounds to hoist. Plan your anchor point before you fill it.
Gravity Bag or Pressurized?
Gravity bags are cheap, light, and simple, but they need a high, sturdy branch or hook. Pressurized showers like the NEMO sit on the ground and use a foot pump, so you don’t hang anything.
The trade-off is cost and bulk. A pressurized shower costs several times more than a bag. Want something that heats on its own at home? See our best solar water heater guide, and our solar power for camping guide for the rest of your camp setup.
Our Picks
Advanced Elements 5-Gallon Summer Shower — Best Overall
This is the benchmark solar bag, and it tops several 2026 test roundups. Its four-ply design stacks a reflector, an absorber, and an insulator around the water, and it has a built-in thermometer so you can check the temperature before you step in.
It typically costs roughly $30 to $40. In one six-week test it showed no leaks or seam failures, while a cheaper single-layer bag developed a pinhole leak in week three.
| Pros | Cons |
|---|---|
| Reaches about 110°F in under three hours of direct sun | Gentle flow, since it relies on gravity alone |
| Built-in thermometer and an on/off switch on the head | The 5-gallon version’s hose is short, about 15 inches |
| Four-ply build, with a good record for durability | Hard to dry fully, so air it out with the top open |
Best for: Car campers and families who want a proven, low-cost warm shower.

Sea to Summit Pocket Shower — Best for Backpacking
At roughly 4 to 5 ounces, this is the lightest option by a wide margin. The 10-liter bag packs to about the size of a fist, comes with a cord and a twist-on showerhead, and doubles as a dry sack.
It gives about seven minutes of shower per fill. Sea to Summit’s pouch even reminds you to shower well away from streams and lakes, which is good practice with any camp shower.
| Pros | Cons |
|---|---|
| Ultralight, and packs to about fist size | Pressure fades as the bag empties |
| Tough taped-seam nylon that doubles as a dry sack | Needs a high, strong anchor point |
| About seven minutes of shower per fill | The roll-top can leak slightly, and grit can clog the head |
Best for: Backpackers and bike tourers who count every ounce.

NEMO Helio LX — Best Pressurized Shower
The Helio LX fixes the biggest complaint about solar bags. A foot pump pressurizes the 5.8-gallon tank, so you get steady spray for 7 to 10 minutes without hanging anything. It comes with a 7-foot hose, and it also works for dishes, pets, and rinsing gear.
It warms gradually in the sun, or you can fill it with hot water. It’s the priciest pick, with NEMO listing it at $199.95 and some retailers lower.
| Pros | Cons |
|---|---|
| Real pressure from a foot pump, with no overhead hanging | By far the priciest pick |
| 5.8-gallon tank and a 7-foot hose | Only warms gradually in the sun, so it’s not a fast heater |
| Sits on the ground, and handles dishes and pets too | Heavier and bulkier than a bag, at about 2 lbs 4 oz |
Best for: Campers who want real water pressure and don’t mind paying for it.

Frequently Asked Questions
How long does a solar shower take to heat up?
About two to three hours in direct sun for the better 5-gallon bags, which reach roughly 110°F.
Do solar showers work on cloudy days?
Not well. On a gray day you’ll need to add hot water from a stove or kettle.
How long does one fill last?
About seven minutes for the 2.6-gallon Pocket Shower. A 5-gallon bag gives enough for a couple of short showers, since its flow is gentler.
Do I need somewhere to hang it?
For gravity bags, yes: a sturdy branch or hook high enough for the hose. The NEMO sits on the ground and needs no hanging point.
Is a solar shower worth buying?
For a few dollars, a gravity bag is a big step up from a bucket in sunny weather. If you camp in cloud or cold, a pressurized shower with hot water is more reliable.
Final Verdict
| Pick | Best For |
|---|---|
| Advanced Elements 5-Gallon Summer Shower | The best all-around solar bag for car camping |
| Sea to Summit Pocket Shower | Ultralight carrying on trail |
| NEMO Helio LX | Real pressure, with no hanging |
For most campers, the Advanced Elements is the right buy. Choose the Sea to Summit if weight matters more than capacity, and the NEMO if you’re tired of a weak trickle.
