Glass vs Stainless Steel Water Bottle — Which Is Better?

Clearly, plastic water bottles are bad for us and the environment, but what about the other two popular types? It’s time for a glass vs stainless steel water bottle battle. 

We’ll dive into details about each type to learn whether it’s safe for drinking, BPA-free, and eco-friendly. Let’s see the pros and cons of each to decide which water bottle is worth our money. Here’s what we’ll cover:

Glass Water Bottles Overview

Glass bottles are made from natural materials and don’t leave any taste or smell on your water. Plus, you can put them in the dishwasher. They seem a good option, but they’re also heavy and prone to break easily. Or are they?

Let’s learn more about glass water bottles and their safety. 

Are Glass Water Bottles Safe to Drink From?

Yes, drinking water from a glass bottle is the safest option. Unlike plastic and some stainless steel bottles, glass won’t leak any chemicals into your water, no matter the circumstances. Besides, most people claim that water tastes better from a glass bottle. 

If you’re worried about chemicals, getting this type of bottle might be the best option for you. Still, I suggest you keep reading because glass bottles have a few disadvantages that might persuade you to go for stainless steel instead.

Is Glass BPA-Free?

Yes, glass is entirely BPA-free. You don’t have to worry about any chemicals leaking from your glass water bottle. 

But is BPA really so dangerous?

BPA or Bisphenol A is a chemical often used in the production of plastic bottles that has a bad rep for being incredibly harmful to the human body. But a surprising volume of scientific studies confirms that BPA is safe for consumers.

Is Glass Eco-Friendly?

Yes, glass bottles are incredibly eco-friendly as they’re 100% recyclable. And we can keep on recycling them forever. 

But if you live in the US, you should keep in mind that only 33% of glass gets recycled, unlike the 90% rate in Europe. The big difference is largely due to government policies and consumer behavior. 

Benefits of a Glass Water Bottle

Glass water bottles have some clear benefits that make them a strong contender for the “Best Water Bottle” prize. Namely: 

  • No leftover smell or taste
  • Made from natural materials
  • 100% recyclable 
  • Durable & scratch-resistant
  • Dishwasher-safe
  • Won’t leach chemicals

And while all that sounds great, I’m still voting in favor of stainless steel bottles. Read on to find out why. 

Disadvantages of a Glass Water Bottle

A glass water bottle sounds great on paper, but it might prove impractical. Here are the main disadvantages you should consider carefully before deciding on this type of bottle:

  • More fragile 
  • Quite heavy
  • No insulation
  • Shorter lifespan

While glass bottles aren’t too fragile, they’re more likely to break than stainless steel bottles. 

But that’s not the big deal. 

The big deal is that they’re way too heavy. If you intend to bring your bottle everywhere, consider carefully whether you want the extra weight. Trust me, it matters. Especially if you’re going hiking. That’s why when it comes to a stainless steel vs glass water bottle, I’ll always go for the steel.

Stainless Steel Water Bottles Overview

Stainless steel bottles are my personal preference. They’re durable, eco-friendly, and entirely safe. What’s there not to like? 

Let’s learn more details and see if I’ll change my mind.

Is Stainless Steel Safe to Drink From?

Yes, a stainless steel bottle is entirely safe to drink from as long as they’re lead-free and insulated. These bottles don’t get corrosion and won’t leach any chemicals into your water.

If your stainless steel bottle smells metallic, you shouldn’t worry. Instead, you should clean your bottle thoroughly and check its quality.

Some people complain that stainless steel bottles give water a metallic taste, but I’ve been using one for several years now and I’ve never had this experience. Perhaps it depends on the manufacturing quality. 

Is Stainless Steel BPA-Free?

Yes, stainless steel is BPA-free. You’ll only have to worry about Bisphenol A if you’re drinking from a plastic water bottle. Stainless steel bottles last for years and are incredibly durable without posing any threats to your health. They don’t leach chemicals into your water and will keep it well-insulated.

Is Stainless Steel Eco-Friendly?

Yes, stainless steel is eco-friendly and 100% recyclable. While it’s true that stainless steel production releases greenhouse gas emissions, most of the production comes from stainless scrap. This considerably reduces the number of toxic gasses. The high recycling rate of the material further reduces carbon emissions by 52%.

And in case you’re wondering, glass manufacturing also releases greenhouse gasses as it involves very high temperatures. Either material can be eco-friendly as long as you take good care of your water bottle and use it for as long as possible.

Stainless Steel Water Bottle Benefits

Stainless steel water bottles have some undeniable advantages that make them a preferred choice:

  • Incredibly durable
  • Eco-friendly
  • Lightweight
  • Insulated
  • Corrosion-resistant
  • No sweat on the bottle

If you want to carry your water bottle with you all the time, lightweight stainless steel is the better option. I highly recommend it for gym enthusiasts, hikers, and anyone who doesn’t want to carry extra weight.

Disadvantages of a Stainless Steel Water Bottle

Stainless steel water bottles don’t have many drawbacks. In fact, they have only one.

Some people claim that water from a stainless steel bottle has a metallic taste. But I’ve been using one for a few years now, and I’ve never felt this. It’s best to try both types of non-plastic water bottles and decide for yourself. If you know someone with a stainless steel water bottle, you can borrow it for a day to see if the taste is weird. Still, keep in mind that the manufacturing quality will also matter.

And the Winner Is…

Glass and stainless steel water bottles are undoubtedly a better choice than plastic. Plus, drinking from plastic bottles is expected to grow by 34% until 2028. That’s one statistic you don’t want to contribute to.

So, a glass vs stainless steel water bottle — which one should you get?

If you’re a hiker or a sports enthusiast, or if you’ll carry your water bottle everywhere, stainless steel is the better choice. It’s lightweight, durable, and insulated. The only reason to pick glass over stainless steel is if you find that water tastes metallic in a stainless steel bottle. Or at least that’s my opinion based on the research I’ve done.

Let me know which one you chose and why in the comments.
