When it comes to RV camping, having a sufficient water supply is essential. Water is not only needed for drinking, but also for cooking, washing dishes, showering, and flushing the toilet. Without enough water, an RV camping trip can quickly turn into a miserable experience.
The recommended water usage per day for an individual is approximately 1.5 to 2 gallons (5.7 to 7.6 liters). However, when it comes to RV camping, there are several factors that affect water usage, such as the number of people in the RV, the length of the trip, and the activities that require water usage.
Today, we will discuss how long 20, 30, 40, 50, and 100 gallons of water last in an RV. We will also provide tips for conserving water in an RV and calculating your daily water usage. By the end of the article, you will have a better understanding of how to manage your water supply on your next RV camping trip.
Factors that Affect Water Usage in an RV
The amount of water you use in your RV can vary greatly depending on several factors. Understanding these factors can help you better manage your water supply and ensure you have enough water for the duration of your trip.
Here are some of the main factors that affect water usage in an RV:
1. Number of People in the RV
The more people in the RV, the more water will be used. Each person will need water for drinking, cooking, and personal hygiene.
2. Trip Duration
The longer your trip, the more water you will need. This is especially true if you plan to use the shower or do laundry in your RV.
3. Activities that Require Water
Activities such as cooking, washing dishes, and showering all require water usage. If you plan to do a lot of cooking or have multiple showers per day, you will use more water.
If you are traveling in hot weather, you will likely use more water for drinking and cooling down. In contrast, if you are traveling in cold weather, you may use more water for heating and washing dishes.
5. Water Tank Size
The size of your water tank is a major factor in determining how long your water supply will last. A larger tank will provide more water, but it will also increase the weight of your RV.
How to Calculate Water Usage in an RV
Calculating water usage in an RV is crucial to ensure that you have enough water supply for your needs. Here’s how you can calculate your water usage:
1. Determine your RV’s water tank capacity
The first step is to determine the size of your water tank. Check your RV manual or look for the tank’s specifications online.
2. Estimate your daily water usage
On average, a person uses about 80-100 gallons of water per day, but this can vary depending on your habits and needs. Here’s a breakdown of estimated daily water usage:
- Drinking and cooking: 2-3 gallons per day
- Showering: 2-5 gallons per shower
- Toilet flushing: 1-2 gallons per flush
- Dishwashing: 3-5 gallons per day
- Handwashing: 1-2 gallons per day
3. Calculate your water usage based on the number of people and the duration of your trip
Once you’ve estimated your daily water usage, multiply it by the number of people in your RV, and the number of days you’ll be on the road. For example, if you’re a family of four and you’ll be traveling for five days, your estimated daily water usage would be 4 x 12 gallons = 48 gallons per day.
Multiply this by the number of days you’ll be on the road, and you’ll get your estimated water usage for the entire trip.
4. Take into account factors that affect water usage
Remember that water usage can vary depending on several factors, such as the weather, the type of activities you’ll be doing, and the availability of water sources along the way. Be sure to take these factors into account when calculating your water usage.
Estimation of How Long Water Lasts in Different Size RV Tanks (20, 30, 40, 50, 100 gallons)
When you’re out on the road in your RV, knowing how long your water supply will last is crucial. It’s important to plan ahead and be mindful of your water usage to avoid running out of water unexpectedly. Let’s take a look at how long water can last in different size tanks.
- 20 Gallons
A 20-gallon water tank can last for around 2-3 days for two people who are conserving water. However, if you are taking long showers or doing a lot of dishes, your water supply may only last for a day or less.
- 30 Gallons
A 30-gallon water tank can last for about 3-4 days for two people who are using water conservatively. However, if you’re taking long showers or doing a lot of laundry, your water supply may last for less than 3 days.
- 40 Gallons
A 40-gallon water tank can last for around 4-5 days for two people who are conserving water. However, if you’re taking long showers, doing laundry, or washing dishes, your water supply may last for less than 4 days.
- 50 Gallons
A 50-gallon water tank can last for about 5-6 days for two people who are using water conservatively. However, if you’re taking long showers, doing laundry, or washing dishes, your water supply may last for less than 5 days.
- 100 Gallons
A 100-gallon water tank can last for around 10-12 days for two people who are conserving water. However, if you’re taking long showers, doing laundry, or washing dishes frequently, your water supply may last for less than 10 days.
It’s important to keep in mind that the estimated days mentioned above are just a rough estimate. The actual number of days will vary depending on your water usage and tank size. Therefore, it’s best to monitor your water usage and refill your tank as needed.

Tips for Conserving Water in an RV
Conserving water while camping in an RV is crucial, especially when you’re off the grid and don’t have access to a freshwater source. Here are some practical tips to help you conserve water:
1. Fix any leaks
Even the smallest leak in your RV’s plumbing system can lead to a significant amount of water wastage over time. Check your pipes, faucets, and showerheads regularly and repair any leaks immediately.
2. Take shorter showers
While it may be tempting to indulge in a long, hot shower, it’s important to keep your showers short to conserve water. Limit your showers to 5-7 minutes, and turn off the water when you’re soaping up or shaving.
3. Use a low-flow showerhead
Investing in a low-flow showerhead can help you save a significant amount of water while still enjoying a refreshing shower.
4. Use a dishpan
Instead of washing dishes under running water, use a dishpan to save water. Fill the dishpan with soapy water, wash your dishes, and then rinse them using a minimal amount of water.
5. Reuse gray water
Gray water is the wastewater generated from your sinks and shower. Instead of letting it go to waste, you can reuse it to flush your toilet or water your plants.
6. Use disposable plates and utensils
While it’s not the most eco-friendly option, using disposable plates and utensils can significantly reduce your water usage. Just make sure to dispose of them properly.
7. Plan ahead
Before embarking on your RV trip, plan your water usage and make sure you have enough water to last the entire trip. You can also carry extra water in portable water containers to extend your water supply.
Proper water management is essential when it comes to RV camping. By understanding the factors that affect water usage in an RV and calculating how long your water supply will last, you can plan your trip more efficiently and avoid running out of water. Remember, the size of your water tank and your water usage habits will greatly impact how long your water lasts.
To conserve water while RV camping, always look for ways to reduce your water usage. This includes taking shorter showers, turning off the water while brushing your teeth, and using a dishpan to wash dishes. Don’t forget to check for leaks in your RV’s water system and to carry extra water with you in case of emergencies.
