Yes, stainless steel water bottles are better than plastic for many good reasons. They are sustainable, eco-friendly and overall good for us and the environment.

Stainless steel is highly recyclable. At the end of its life, you can send your stainless water bottle to your local recycling plant and they will turn it into something entirely different. While technically, plastic bottles are recyclable but more often than not, they end up piling in our landfills and floating in bodies of water.

If you are still on the fence about stainless steel water bottles, here are the reasons why they’re better than plastic bottles:

Environmental Impact

Unfortunately, single-use plastic drinking bottles contribute a lot to plastic waste. These disposables are piling up in our landfills and littering our oceans. They are non-biodegradable which means it takes hundreds, if not thousands of years before they decompose. And if they break down, they become microplastics which pose a huge threat to marine life. When they are buried in our landfills, they contaminate the soil with toxic chemicals, rendering the soil infertile.

Imagine if a vast area of land is covered with plastic. Wide deforestation and soil erosion that leads to floods could happen. This problem can affect the majority of living organisms. It makes the land inhabitable with no chance of propagation of plants for food and resource.

Not only on land, but plastic also causes a myriad of problems to bodies of water. They are a threat to marine life because they cause suffocation making the water not ideal in becoming a source of food and a shelter to aquatic lives. In the air, plastic can contribute to greenhouse gases when they are burned. This can lead to climate change and global warming. Again, the environment is at stake.

Using a stainless steel water bottle can help prevent all of these terrible things from happening, thanks to the reusability property. No disposal after use, no pollution contributed.

Durability and Temperature Retention

Have you ever tried adding hot water to a plastic bottle? Maybe out of curiosity you did but what happens next is that the plastic shrunk, distorted and deteriorated. It is because plastic bottles are so thin that they can never withstand extreme temperature.

On the contrary, most if not all stainless steel water bottles feature double wall vacuum insulation which allows them to keep beverages hot or cold for extended periods of hours. They even let you handle the heat without scalding or burning your hands.

Extreme conditions such as throw and drops are manageable and handled effortlessly by stainless steel water bottles. But plastic? Not so much. Some can even break and leak.

Better for Our Health

Plastics contain toxins and chemical compounds like BPA or bisphenol-A that are detrimental to human health and the environment. BPA is linked to many health problems like heart disease, infertility, male impotence, hormone disruption and is widely considered as carcinogenic.

Prolonged exposure to heat and sunshine for example if you leave your plastic bottle inside your car, could potentially cause toxin leakage. Conversely, stainless steel water bottles are safer to use. They don’t impart or alter flavours which can be great if you transition from one drink to the other. They are even rust-proof and resistant to bacterial and mould growth.


Plastic bottles, although cheaper, are not considered as cost-effective due to them being single use.The less chance of reusing the product, the bigger chance of shedding money.

Yes, the initial investment for stainless steel water bottles is high but it’s one of the minor trade-offs we can all live with considering the benefits we get from using them. They are durable enough to last for many years, some claiming up to 12 years before you need to replace your water bottle. Wherever there is potable water, you can use and fill the reusable water bottle without spending money.


Honestly, plastic water bottles are dull and boring. Once it’s empty it already loses its luster. Who would ever carry around an empty transparent plastic water bottle? No one because it is never stylish.

However, stainless steel water bottles are gorgeous. They come in beautiful patterns, prints and designs. Chilly’s Bottles for example have unique, colorful and pretty designs that you can choose from. There’s Icon Avocado, Tropical Flamingo, Metal Rose Gold and many more.
