Why Build a Solar Shower?

When camping or staying in a remote cabin, warm water can feel like a luxury. A solar shower uses sunlight to naturally heat water, giving you an eco-friendly way to clean up after a long day outdoors. It’s inexpensive, simple to set up, and requires no electricity.

What You’ll Need

Gather a few basic items to get started:

Black plastic or PVC bag (5–10 gallons): Black absorbs sunlight and heats faster.
Sturdy rope or cord: For hanging the shower.
Shower nozzle or simple spout: Many kits include one.
Optional insulation or reflective tarp: Helps retain heat longer.
Tree branch, tripod stand, or overhead support: To hang your shower.

Step 1: Choose the Location

Select a sunny spot with strong overhead support:

Direct sun exposure for at least 4–6 hours.
Flat, stable ground to prevent tipping.
Privacy: Use a tarp or portable shower tent if needed.
Easy drainage: Away from camp kitchens or sleeping areas.

Step 2: Prepare the Water Container

You can buy a pre-made solar shower bag or make your own:

Bag method: Fill the black bag with clean water and seal tightly.
DIY PVC option: Attach a black PVC pipe to a hose bib with a simple spigot. Paint it black if it isn’t already.

Tip: Pre-filter the water if it comes from a stream or lake to remove debris.

Step 3: Set Up and Heat

Hang the bag or pipe high enough so gravity provides water pressure.
Place the container where sunlight hits it directly for most of the day.
Let the sun warm the water. In full sun, temperatures can reach a comfortable 100–120°F (38–49°C) in about 4 hours.

Step 4: Add the Shower Head

Connect the included nozzle or attach a simple spout or garden sprayer.
Check for leaks and tighten any connections.
Test water flow before showering.

Step 5: Enjoy and Maintain

Rinse off dirt before soaping up to conserve warm water.
Drain and dry the container after each use to prevent algae or bacteria growth.
In colder seasons, empty the container at night to avoid freezing.

Tips for Better Results

Use dark-colored containers to speed up heating.
Add an insulated wrap or reflective blanket around the bag to keep heat longer.
Place the shower on a raised platform if trees or hooks are unavailable.
Bring biodegradable soap to minimize environmental impact.

Final Thoughts

A solar shower is an easy, eco-friendly way to stay clean while camping or living off-grid. With just a few supplies and a sunny spot, you can enjoy warm water almost anywhere—no electricity required.
