Water should be one of your primary considerations before you head out camping. Some campsites offer fresh water, but others don’t. Therefore, you need to know how much water to carry for drinking, cooking, and personal hygiene.

You need five US gallons (18.9 liters) of water for a camp shower. Additionally, few camp showers hold beyond five US gallons (18.9 liters). You can survive with fewer gallons, but you need to be a pro at water conservation and have a shower with a slow flow to pull it off.

Now that you know how much water you need for a camp shower, I’ll let you in on the different shower options you have for camping. I’ll also explain how best to save shower water when camping. 

Why Five Gallons (18.9 Liters) Is the Magic Number

Showering during camping feels nothing like showering at home. The flow rate from camp showers is much slower, translating to less water needed for the shower. However, you will still enjoy a refreshing shower with less water.

You need five gallons (18.9 liters) because most camp showers hold that amount of water. Due to the decreased flow rate of camp shower heads, you’ll take a complete ten-minute shower with five gallons (18.9 liters). 

Your body size will also dictate how much water you need for a camp shower. If you are a six-foot-four (1.93-meter) football linebacker, expect to use more water than a ten-year-old kid. 

Nevertheless, five gallons (18.9 liters) should be enough for both of you. The difference is that a ten-year-old kid will leave the shower with a couple of gallons to spare.

Camping showerheads are typically smaller and utilize smaller pins to save water. Therefore, they use less water compared to home showers. 

You can use up to 30 gallons (113.6 litres) of water for a ten-minute shower at home. During camping, five gallons (18.9 liters) will serve you just as well. 

This stat demonstrates how much water we waste using home showers.

How To Save Shower Water During Camping

Water can prove to be a very precious commodity during camping, especially if you don’t have a freshwater body near you to fetch water. Therefore, you must use water as conservatively as possible. Showering consumes a lot of water, but you can save plenty using a simple trick. 

Turn off the water when not in use. We waste a lot of shower water by leaving the shower on during lathering, for example. When camping – and even at home – you don’t need to have the shower on throughout the entire bath. 

A system called the navy shower can help you save plenty of water during camping. Spend the first 30 seconds getting wet under the shower, then switch it off.

Lather your body, and turn on the shower for a minute to rinse off. The target is to spend less than two minutes under the shower. 

By doing this, you’ll save a ton of fresh water. 

If the navy shower is too tough for you, save water by using a low-flow showerhead. It reduces the rate of water flow, resulting in reduced water use.

What Are the Types of Camping Showers?

The different camping showers have three things in common: 

  • A water reservoir
  • A hose
  • A showerhead

They differ in heating capabilities and methods, complexity, and price.

The types of camping showers available are:

  • Canvas
  • Solar
  • 12V showers
  • Gas-heated showers
  • Car-fitted showers

I’ll look at each of these in greater detail to help you choose the best one for your camping trip. 

1. Canvas

Canvas showers are the simplest type of camping showers available. 

They have a hose, a reservoir, and a showerhead. Canvas showers depend on gravity to work, so you need a place to suspend the bag, like a tree branch. 

You also need an improvised screen to shower using a canvas shower or get comfortable with showering in the open. The bag is too heavy for a shower tent, so you’ll need to get creative to secure privacy. 

You’ll have to preheat the water if you must shower with warm water. 

The main advantage of a canvas shower is its simplicity. Fill the reservoir with water, find a private spot, and get to showering. 

2. Solar

A solar camping shower is just like a canvas shower, but this one uses the sun’s energy to heat water for you. 

The cover is made of heat-absorbent material that heats the water using sun rays. All you need to do is leave the full bag out in the sun and let nature work its magic. 

You’ll wait several hours before the water heats up. Therefore, ensure that you maximize the time when the sun’s hottest. 

You can accelerate the heating by placing the bag on a metal surface, for example, a car bonnet. Before you start showering, ensure that the water’s not too hot. 

Just like the canvas shower, the solar shower needs gravity to work. A tree branch would work best, considering that the bag is too heavy for a shower tent. 

An advanced type of solar shower can be mounted on your vehicle’s roof rack. That way, the water heats up as you move around. 

This type of solar camping shower doesn’t take up much space. The vehicle’s height also presents a high-enough mounting point for the shower. 

However, you’ll have to bathe very close to where you park your vehicle. 

The main disadvantage with solar showers is that no sun means no hot water.

12V showers address the water pressure disadvantage plaguing the solar and canvas showers. 

The 12V shower comes with an electric pump that you place inside the reservoir. The pump provides water pressure to facilitate a relaxing shower. 

Since you don’t have to hang the tank overhead, you can bathe inside a water tent using the 12V shower. 

However, hot water enthusiasts must still heat the water before showering. 

The Ivation Portable Outdoor Shower from is an excellent option for this category. It utilizes rechargeable batteries that you can fill using any USB port. 

At full charge, the shower will give you one hour of continuous use. 

4. Gas-Heated Showers

This is one of the options for a camper that can’t do without a hot shower, but it isn’t cheap.

These showers use propane to heat your shower water and a battery-driven pump to deliver it.

Some of these showers allow for the regulation of water temperature. They come in wide varieties, so you will get one that suits your needs. 

The more advanced your shower gets, the more you’ll have to shell out. 

A gas-heated shower can prove to be a worthwhile investment during an extended camping trip. Having to heat your water every day can be tiring and inefficient. 

5. Car-Fitted Showers

If camping is the sort of thing you do regularly with your car, you should consider a car-fitted camping shower

The shower’s pump uses power from your engine to pump water from the reservoir. It uses the heat generated by your engine to heat your shower water. 

You regulate the shower water’s temperature in the same way you regulate your car’s internal temperature. With a car-fitted camping shower, you’ll really enjoy your showers, especially if you park close to a body of water. 

I advise that you invest in a long outlet hose so you can set up a shower tent next to your car.


Five US gallons (18.9 liters) will work well regardless of whichever type of camping shower you use.

You can use far less than five gallons (18.9 liters) per shower if you shower conservatively. Try the navy shower and marvel at how much water you save.
