What Are Solar Showers?

Solar showers are innovative devices that utilize the sun’s energy to heat water, providing an eco-friendly way to shower outdoors. They are particularly popular among campers, hikers, and outdoor enthusiasts, as well as homeowners seeking an energy-efficient way to add a shower to their pool or garden area. Here’s an overview of what you need to know about solar showers, including their benefits, how they work, and some recommended products based on my research.

How do Solar Showers Work?

Solar showers absorb heat from the sun and transfer it to the water contained within a special bag or tank. These bags are typically made of durable materials like PVC and are colored black to absorb solar heat effectively. They can heat water to temperatures ranging from 113°F to 120°F, sufficient for a comfortable shower without the risk of burns​​.

Benefits of Solar Showers


Solar showers offer a range of benefits that make them an appealing choice for outdoor enthusiasts and eco-conscious individuals alike. Here are some key advantages:

  • Eco-Friendly: Utilizes renewable solar energy to heat water, reducing reliance on non-renewable energy sources​​​​.
  • Cost-Effective: No electricity or fuel required, saving money on energy bills and reducing operational costs​​​​.
  • Portability: Lightweight and easy to transport, making them ideal for camping, hiking, and other outdoor activities​​​​.
  • Easy to Use: Simple setup and operation, with no complicated installations or maintenance required​​​​.
  • Temperature Control: Many models come with temperature indicators or gauges to ensure water is at a comfortable temperature​​​​.
  • Water Efficiency: Promotes the conservation of water by controlling the flow rate and reducing wastage​​.
  • Versatility: Can be used in various settings, including camping sites, gardens, pools, and remote areas without access to hot water​​.
  • Safety Features: Includes design elements like durable materials and leak-proof constructions to ensure safe use​​​​.

These benefits highlight the practicality and sustainability of solar showers, offering a convenient solution for warm showers in the great outdoors or in any situation where traditional hot water access is limited.

Types of Solar Showers


The versatility of solar showers makes them suitable for a wide array of applications, from backcountry camping to luxury poolside amenities. Understanding the different types available can help you choose the right one for your needs. Here’s a more detailed look at the main types of solar showers:

1. Portable Bag Showers

These are the most common and convenient type of solar showers, designed for ease of use and mobility. They typically feature:

  • Capacity: Ranging from 2 to 5 gallons, which is enough for several minutes of showering. Larger bags can hold up to 10 gallons, providing enough water for multiple showers.
  • Material: Made from durable, heat-absorbent materials such as PVC or rubber, these bags are designed to capture and retain solar heat efficiently.
  • Design: Black in color to absorb more heat, with a clear section or temperature gauge to monitor water temperature. They often come with a hose and showerhead attachment for ease of use.
  • Portability: Lightweight and foldable, these bags can be easily packed in a backpack for hiking, camping, or any outdoor activity.

2. Permanent or Semi-Permanent Solar Showers

Designed for installation in a fixed location, such as beside a pool, in a garden, or at a permanent campsite, these showers offer more durability and can be a more integrated part of outdoor decor. They typically feature:

  • Construction: Made from weather-resistant materials like stainless steel or weather-proofed wood, these showers are designed to withstand the elements.
  • Water Capacity: Depending on the design, they may have a built-in reservoir that is filled manually or connected to an external water source.
  • Heating Method: Some use solar panels to heat water directly, while others heat the water indirectly by circulating it through a solar-heated coil.
  • Installation: They require a more permanent setup, often including a concrete pad or secure mounting to a deck or patio.

3. Hybrid Solar Showers

These showers blend elements of both portable and permanent solar showers. They might feature:

  • Versatility: Designed for easy setup and breakdown, these can be moved between locations but offer a more substantial structure than a simple bag.
  • Heating Efficiency: With advanced features like integrated solar panels or a heat-exchanging design, these showers heat water more efficiently and maintain the temperature longer.
  • Capacity and Features: Offering larger water capacities than portable bags and often including amenities like temperature controls, foot washes, or even filtration systems.

Choosing the Right Type

When selecting a solar shower, consider the intended use, the number of people using it, and the availability of sunlight in the area. For solo campers or hikers, a lightweight portable bag shower might be perfect. Families or groups might benefit from a larger bag or a hybrid model. For those seeking a more luxurious or permanent solution for their home, garden, or poolside, a permanent solar shower would be the best choice.

Each type offers a unique set of benefits tailored to different settings and needs, ensuring that there’s a solar shower option suitable for virtually any outdoor living or adventure scenario.

Considerations When Choosing a Solar Shower

When selecting a solar shower, consider factors such as capacity, heating time, materials used, weight and size, and extra features like water flow control and temperature indicators. Large-capacity models are ideal for groups or longer trips, while smaller, lightweight options are perfect for solo travelers. The material should be durable enough to withstand outdoor conditions, and additional features can enhance the convenience and user experience​​.

Using Solar Showers Effectively

For best results, place your solar shower in a sunny spot to maximize heat absorption. Remember, it can take several hours for the water to heat up, so plan accordingly. Always test the water temperature before use to ensure it’s comfortable and not too hot. Mixing cold water can adjust the temperature if needed​​.

Solar showers offer a convenient and eco-friendly way to enjoy warm showers outdoors, whether you’re camping, at the beach, or have a pool at home. They embody a simple yet effective solution for outdoor hygiene, capitalizing on renewable energy to provide comfort and convenience in remote locations or wherever access to hot water might be limited.
