The rigors of a day in the outdoors may want you looking for a hot, refreshing shower. But in order to heat water, you may have to burn fuel such as propane or wood. Enter the solar showers to the scene! Though energy from the sun has been at the center stage of energy supply for centuries, gravity based solar showers were first conceived in 1985.
In this article, we look at some of the best portable solar showers available in the market. We will focus on the gravity based showers which can be elevated on a tree, pole or car under the sun to heat water and use gravity to maintain flow, rather than relying on any sort of pump. These showers are compact enough to carry when not in use.
While these showers come in different sizes, we will focus specifically on 5-gallon capacity showers (20 liters), as such showers can provide a light bath to 2-3 people.

What is a portable solar shower and how it works?
A portable solar shower is a gravity based gear that consists of a water container which can be exposed to the sunlight to hear water. A typical solar shower consists of a nozzle valve to fill water, a hose with a shower head, along with the shower bag. Since it relies on gravity to manage the flow of water, a solar shower must be elevated and hoisted on a tree branch, pole, or a car. Solar showers can be used for light bath, cleaning utensils, washing clothes and even cleaning your gear such as a surfboard. Solar showers are quite handy in outdoor activities such as camping, hiking, fishing, sailing, beach fun, and kayaking.
The key component of the solar shower that makes all it happen is the shower bag. Most high-end solar showers have bags with a 4-layer construction, though some other shower bags also have a 3-ply construction. The shower bags are made up of non-toxic PVC or PVA. Each shower bag has two sides – see through, black color coated, flexible solar panel side which is exposed to the sun and the operating side of the nozzle, shower head, and optional mesh pocket. It is important that you expose only the solar panel side to the sun.
Solar showers come in different capacities ranging from 2.5 gallons to 20 gallons. However, 5-gallon (20 liters) shower is most suitable for camping and other outdoor activities. The solar panel in a 5-gallon solar shower can heat water to 100o-110 o F in about 4-5 hours of exposure to sunlight. Most high-end solar showers also come with a temperature gauge to give an indicative temperature of the stored water.
How to pick the best portable solar shower?
Picking the most suitable solar shower is largely about picking the best shower bag. You would want to pick a portable shower with a durable, efficient and easy-to-handle shower bag. Specifically, in order to pick the best solar shower, you should consider the following factors:
- Building material of the shower bag
- Size and weight of the solar shower
- Nozzle, shower head and valve
- Additional features
Building material of the shower bag
The building material of the shower bag is probably the most important criterion to consider while buying a portable solar shower. While some solar shower bags are also made of non-biodegradable PVC plastic, almost all the options listed above are made of non-toxic PVC or PVA. High-end solar showers such as the Advanced Elements Summer Shower also have a non-PVC ripstop version also available.
High-end solar showers such as Ivation Portable Outdoor Shower and Advanced Elements Summer Shower have a four-layer construction. These four layers consist of the reflector layer, the insulator layer, the solar panel layer and the water reservoir layer. This 4-ply construction makes the shower efficient and durable, though, this may also make it a little heavier to carry.
So check the building material and construction design while picking the most suitable option.
Size and weight of the solar shower
If you are backpacking or hiking and carrying your own supplies, the weight of the empty solar shower becomes important criteria to consider. Thankfully, almost all the solar showers are reasonably lightweight, with a weight less than 2 pounds (24 ounces) and hence comfortable to carry along. The basic Coleman Portable Solar Shower is the lightest of all at around 0.6 pounds (it has 3-ply construction and does not include a temperature gauge).
Nozzle, shower head and filling valve design
The nozzle, shower hose, and shower head are important parts of a solar shower. Some popular solar showers such as Sportneer Solar Camping Shower and Advanced Elements Summer Shower have on/off heads to regulate the water flow, while other solar showers have on/off nozzles to regulate the flow. On/off shower heads are generally more comfortable to use. Similarly, check the reviews of the solar shower you want to buy to see if there are any common issues with leaking valves.
The diameter of the filling valve is another important thing to check out. Wider the filling valve, easier it is to fill, drain and clean the solar shower. You can check out the specifications and reviews of the solar shower to determine the suitability.
In addition to the factors listed above, there are some additional features that can make a solar shower purchase attractive.
One of the most important such features is the built-in temperature gauge. A temperature gauge can help in indicating the temperature of stored water and also act as a level indicator. Try to pick a shower which has such a temperature gauge, preferably on the lower side of the shower bag.
Long hose pipes, Velcro straps and mesh pockets with mirrors are also good accessories to have. Moreover, the Sportneer Solar Camping Shower comes with a mesh carrying bag, making it an extremely attractive buy. For other solar showers, this is an additional accessory to buy.
Look out for such additional features to determine if a particular solar shower would best suit your needs.

General Usage guidelines
Please keep the following things in mind while using the portable solar showers:
- Never fill the shower bag beyond the maximum advertised capacity. Since the shower bags are made from lightweight PVC/PVA material, they are not super-durable. You can use the see-through side or temperature gauge to determine the water level in the bag.
- Since the shower bags are made from PVC or PVA, they should not be used to carry drinking/potable water, even though the PVC used is marked non-toxic. Because of heating, there may be scaling in the shower bag. It is, however, fine to use the shower to wash clothes, utensils or gear.
- Always ensure that only the prescribed see-through side is exposed directly to the sunlight. Exposing the wrong side can damage the shower bag. The side with texture, hose, Velcro straps etc. is the wrong side.
- Always monitor the reading in the temperature gauge before using the water in the shower. Though these gauges may not be 100% accurate, the readings give a decent idea about the stored water. If your shower does not have a temperature gauge, run a little water through the hose and feel it to determine its suitability for use.
- Since the body of shower bag is flexible, nozzles and valves are not that sturdily attached. Handle them with care to ensure a long life for your portable shower. Do not twist the valves beyond their twisting capacity.
- If you find it difficult to elevate a filled shower bag on a branch, you can tie a paracord or rope to the handle/handle strap and then fill in the water, and hoist the bag using the rope/cord. Just make sure that the rope is sturdy enough to withstand the weight of a filled shower bag.
Cleaning your solar shower bag
Because of continuous reuse, you may need to clean up your solar shower after a while. This is necessary to ensure that you do not have any mildew or mold build up in the bag.
To do so simply take some common domestic bleach cleanser (or better, bleach packs or bleach crystals), add recommended amount of water and let it stand for an hour or so. You can even add a small amount of mild fabric detergent to the mixture. Then, shake the bag and let the mixture flow through the nozzle. After that, rinse the bag with plenty of water and let it flow a couple of times more. To dry the shower bag, leave it to dry in the shade.
