Stainless Steel vs Plastic Water Bottles: Which One's the Best?

5 Reasons Why Stainless Steel Water Bottles Reign Supreme

Since reusable water bottles were introduced to the public arena back in 1947 after World War II, they have slowly but steadily cemented themselves as a staple of everyday life for many people.

Seeing as plastic was so readily accessible back in those days, polyethylene water bottles became all the rage, for better or for worse.

As time passed, the negative health and environmental impacts of plastic water bottles became apparent, and stainless steel water bottles were introduced roughly 50 years later.

Let's take a look at the stainless steel vs plastic debate and review five reasons why stainless steel water bottles are far superior to plastic water bottles, answer some FAQs, and discuss the best stainless steel water bottle out there.

Topics Covered in This Guide

Environmental Impact

We all know how devastating plastic bottles are to the environment, but let's take a look at some eye-opening statistics regarding plastic products.

Aside from the visible pollution we see with our own eyes every day, waste from disposable water bottles that wash into the ocean kills 1.1 million marine animals every year.

There are also giant garbage patches, or plastic soup, that form offshore in the middle of the ocean, with the most notable being the Great Pacific Garbage Patch in the center of the North Pacific that measures roughly 1.4 million km².

Stainless steel water bottles do not contribute to that horrendous oceanic plastic bottle pollution at all. These reusable bottles are also much more durable and long-lasting than a plastic water bottle, reducing overall plastic pollution.

Plus, if you choose a quality reusable water bottle made from Greens Steel that lasts a lifetime, you can rest assured that your water bottle choice will have a 0% impact on global pollution.

Temperature Retention

The temperature retention of plastic water bottles is next to nothing. Once you take a frozen or chilled drink in a plastic water bottle out of the fridge or freezer, it will quickly heat up and melt, which also leads to condensation on the outside of the water bottle. This will leave a nasty soup in your cup holders, bags, or desk.

Unlike plastic, stainless steel bottles can keep your chilled drinks cold for up to six hours and heated drinks hot for up to twelve hours with zero condensation.


Let's be clear on this massive plastic problem; everyone's heard that drinking out of plastic bottles is "bad for you", and although this is true, nobody really knows why this is so.

Long story short, plastic water bottles leach chemicals into your drinks, especially with hot liquids. Here's a list of just some of the health concerns that come from drinking water out of plastic water bottles and how they leak toxic chemicals into your body.

• BPA from both single use plastics and reusable plastic bottles is linked to blocking the action or hormones and disrupts the balance of them, potentially leading to stubborn belly fat, mood swings, and hormonal imbalances.

• Carcinogenic phthalates disrupt the endocrine system and are also linked to male fertility issues, diabetes, obesity, and attention deficit hyperactivity disorder.

 Aside from leaching unwanted chemicals, plastic bottles are also notoriously difficult to clean and can easily become an out-of-control breeding ground for bacteria. This can lead to bad tasting and smelling water as well as digestive issues.

Switching to stainless steel bottles totally eliminates all of these health concerns as they contain no plastics aside from the lids. As long as the reusable bottle lids are BPA free, you're good to go. They're also very easy to clean, and bacteria can not grow on 18/8 food grade stainless steel.

Durability & Longevity

Plastic water bottles easily shatter or crack when dropped and warp when hot liquids are added to it. As we mentioned above, adding hot drinks to plastic bottles pulls out many toxic chemicals, that are bad for fertility, weight, and other health concerns.

Even if you do manage to not drop it, plastics wear down pretty fast. If colors or designs are sublimated onto the outside of the water bottle, they will flake, chip, and peel off in just a few months time.

The only thing that can really destroy a stainless steel bottle is an 18 wheeler truck running it over. Aside from that, dropping, toppling, or knocking over your stainless steel bottle really won't leave more than a slight scratch - stainless steel products can easily withstand multiple drops.

Plus, the colors and designs added to stainless steel bottles are applied in such a way that they simply can not come off.


While plastic bottles may seem cheaper in the short term, it will cost you more money in the long term once you have to replace it - and you will have to replace it again and again.

Seeing as our stainless steel bottles are made to last a lifetime, and come with a lifetime warranty, going the stainless steel route is a once-in-a-lifetime purchase. 

No matter how you slice it, stainless steel water bottles are the more cost-friendly option.
