How Long Can Bottled Water Be Stored at Room Temperature?
Bottled water can be stored at room temperature for up to 2 years if it is properly sealed and kept away from air, light, and heat sources. However, it should be noted that if stored outside in the sun or exposed to high temperatures, the water will begin to lose its taste and quality.

The shelf life of bottled water is determined by the chemicals in the plastics it’s packaged in. As these chemicals break down, they leach into the water, which can affect its taste and flavor. In addition, drinking water that has expired may cause health problems including hormonal imbalances, immune suppression, cancer, and birth defects.
If the plastic has been left out for too long, it will also degrade and may leak chemicals into the water. This is why a best-before date is often printed on bottled water containers.
When storing bottled water, it’s important to store it in the refrigerator rather than at room temperature as this will allow for better storage. The fridge will also help the plastic maintain its composition and will keep bottled water fresher for longer.
The refrigerator will also keep the water cooler, which will prevent it from absorbing the sun’s UV rays and heat. This can reduce the risk of bacteria growth, which will cause a change in taste and smell.
If you’re storing the water at room temperature, it’s a good idea to seal the lid tightly and don’t touch the bottle with your hands as this can also contaminate the water. You can also write the date you bought it on the side of the bottle, which will help you ensure that it’s not been stored longer than recommended.
Ideally, the shelf life of bottled water should be two years. Sadly, this is not always possible. This is because the plastics used for bottled water will start to leach chemicals into it sooner than this, even when the two-year expiry date is printed on them.
In fact, it can happen sooner than that if the bottle is left out in the sun or in excessively hot climates. In this case, the water can begin to taste and smell like plastic and will begin to lose its original taste.
When you’re storing the water in the refrigerator, it’s best to place the bottles upright as this will prevent them from tilting and falling over which can also lead to a loss of the water’s flavor. It’s also a good idea to place the bottles in a closed drawer or cabinet to prevent any air from getting into them.
Another way to make sure the water is safe to drink is to check for any mold or mildew. These can grow inside the bottle over time, and if they have not been treated with any chemicals, they can pose health risks.
If you find any of these issues in your bottled water, it’s a good idea to discard the water as soon as possible. This will help avoid any bacterial and/or mold buildup in your home and will ensure you’re drinking fresh, clean, and healthy water.
