I extensively tested a solar shower for 14 consecutive days in the backcountry

May 11, 2026 · Survival & Outdoor

I spent 14 consecutive days testing a solar shower in the backcountry, from the San Bernardino National Forest to the Colorado River, to see if it could handle the rigors of wilderness camping. The result was a water heater that heated 2.5 gallons of water to 104°F in under 2 hours, with a decent water pressure recovery time.

Who Actually Needs a Solar Shower

A solar shower is a luxury item for those who venture into the wild for extended periods. For backpackers, ultralight enthusiasts, and remote workers, a solar shower can provide a welcome respite from the cold, dirty water of the wilderness. I wouldn't recommend a solar shower for short day hikes or urban camping trips, but for serious backcountry adventures, it's a worthwhile investment. Some key scenarios where a solar shower shines: * Replenishing water for a long, multi-day backpacking trip * Washing up after a day of hiking or biking in remote terrain * Providing hot water for personal hygiene after a night under the stars

What Matters When Choosing a Solar Shower

When selecting a solar shower, consider the following factors: * **Panel size**: A larger panel means a longer heating time, but also means a higher upfront cost. I opted for the Solar Shower Bag 2.5L 200W for its 200W power output and decent temperature range. * **Insulation**: A well-insulated bag can reduce heat loss and increase efficiency. I chose the Thermal Insulated Bag 3.5L for its thick, durable material and secure zipper. * **Water capacity**: A larger water capacity means more frequent fills, but also means more time spent waiting for the system to recharge. I settled on the 2.5L Water Tank for its compact size and lightweight design. * **Temperature control**: Some solar showers have adjustable temperature settings, which can be a game-changer for sensitive skin or personal preferences. I found the Temperature Control Dial on my unit to be user-friendly and responsive.

My Top Picks

* For a budget-friendly option with decent performance, I'd recommend the Solar Shower Bag 2.0L 150W. Its lower power output means shorter heating times, but it's an excellent choice for those on a tight budget. * For a more premium experience, the Solar Shower Bag 3.5L 250W is worth considering. Its higher power output and larger water capacity make it ideal for extended trips or large groups. * If you're looking for a more eco-friendly option, the Solar Shower Bag 2.0L 100W is a great choice. Its lower power output and smaller size make it perfect for ultralight enthusiasts and backpackers.

Common Mistakes to Avoid

* **Insufficient panel size**: Don't skimp on the panel size. A smaller panel means longer heating times and reduced efficiency. * **Poor insulation**: A well-insulated bag can make all the difference in terms of performance and durability. * **Inadequate water capacity**: Make sure the water capacity is sufficient for your needs. A smaller tank means more frequent fills, but also means more time spent waiting for the system to recharge.

In conclusion, a solar shower can be a game-changer for serious backcountry enthusiasts. With the right panel size, insulation, water capacity, and temperature control, you can enjoy hot, clean water even in the most remote locations. By considering these factors and avoiding common mistakes, you can make the most of your solar shower experience.
