Whether it’s ice-cold water for a long sweaty hike or a hot coffee wake-up kick on your morning commute, you need a good quality reusable water bottle to ensure you stay hydrated.

With the abundance of different reusable water bottle materials on the market, it can be challenging to decide which one is right for you.

Don’t panic! I’m here to help…and I’ve brought my obsessive research skills with me!

In this article, I’ll dive deep into some of the most common materials for reusable bottles so you can make an informed decision about the best water bottle choice for your eco-friendly lifestyle.

How to Choose a Reusable Water Bottle: Six of the Best Materials for Sustainable Supping

Do you think your water bottle choices are limited to plastic and glass? Think again!

Reusable water bottles come in various materials, each boasting unique benefits and pros and cons.

How and where you’ll use the bottle will dictate the best material for you.

From classic stainless steel to ancient copper, there’s an option available for every eco-friendly consumer looking to reduce their single-use plastic consumption.

Check out my environmentally friendly water bottles article for my review of the best options currently available.

Glass Reusable Water Bottle

Glass water bottles aren’t as durable as other reusable water bottles (although many glass bottles come with protective silicone sleeves to help avoid breakages).

However, they’re still an excellent choice because they are non-porous and won’t retain any lingering taste or odor.

Pros

  • A healthy choice because it doesn’t leech any chemicals into your drink
  • Can be recycled at the end of its life cycle
  • You can use borosilicate glass water bottles for hot and cold drinks
  • Easy to clean with hot water and eco-friendly dish soap
  • Customizable with decorative (and protective) silicone sleeves
  • Dishwasher safe

Cons

  • Easily broken
  • Can be heavy/bulky
  • Often expensive
  • Not a good choice for children

Stainless Steel Water Bottles

Stainless steel water bottles are safe to use, are incredibly durable, and easy to keep free from mold due to being able to be cleaned with boiling water.

While not offering quite as pure a drinking experience as glass, stainless steel bottles still offer an entirely non-toxic drinking experience (providing it’s made from high-quality 18/8 food-grade stainless steel).

Pros

  • Durable and long-lasting (could last a lifetime with proper care)
  • Easy to keep sterile
  • No harsh chemicals
  • Maintains drink temperature (especially double-walled options)
  • Suitable for hot and cold drinks
  • You can recycle stainless steel bottles many times

Cons

  • Cheaper versions might give off a metallic taste
  • Metal water bottles can be heavy/bulky
  • Stainless steel is often expensive

Aluminum Water Bottles

Aluminum bottles are popular because they’re usually cheaper than a stainless steel water bottle.

However, they must be lined with plastic, enamel, or epoxy resin to prevent the metal from being attacked and broken down by acidic drinks.

Pros

  • Lightweight and easy to carry around (good for exercise)
  • Fast-drying, so won’t retain any lingering odors or taste after washing
  • Cheaper than stainless steel and glass

Cons

  • Has to be lined (leading to concerns about chemicals leaching into the water)
  • Can make water taste metallic
  • Easily damaged when dropped

Plastic Water Bottles

Plastic bottles have a bad reputation. Disposable plastic water bottles, in particular, are an environmental nightmare that adds to the global plastic waste crisis.

However, when you invest in reusable plastic bottles, you’re making a better environmentally conscious choice than using disposable plastic bottles.

BPA-free plastic bottles are considered safe, but some people are concerned about chemicals passing from the plastic into their water.

Various types of plastic are used for reusable plastic water bottles. Check the recycling symbol (usually on the base) to discover what your plastic drinks bottles are made from.

Pros

  • Available in a wide range of sizes, shapes, and colors
  • Inexpensive
  • Lightweight and portable

Cons

  • Not recommended for hot drinks
  • Potential for chemicals to leach from plastic
  • Will distort in extreme temperatures
  • Possible plastic taste when new

Copper Water Bottles

Copper water bottles have long been used in Ayurvedic medicine to improve the digestive system and overall health.

Today, they’re praised for reducing bacteria and neutralizing compounds that cause bad taste or odor.

They can also help keep your drink at optimal temperature longer than glass or plastic bottles.

Pros

  • Naturally antibacterial
  • Some believe copper enhances overall health by promoting energy flow and well-being throughout the body
  • Keeps cold water (and Moscow Mules! ????) cold
  • Looks cool
  • Durable

Cons

  • Potential for oxidation or discoloration
  • Heavy to carry around
  • Can cause stomach aches in some people
  • Metallic taste
  • Often more expensive than plastic or metal bottles

Silicone Water Bottles

Silicone water bottles are not massively popular, but some people consider them the best choice for multiple reasons.

They’re lightweight and portable, making them easy to take wherever you go. You can even get collapsible versions.

They’re also durable and won’t leach chemicals into your water like plastic or aluminum can.

However, they can be hard to clean properly and may retain stains. And don’t put them in the dishwasher. It’s better to hand-wash silicone water bottles to keep them looking their best.

Pros

  • Lightweight and portable
  • BPA-free, non-toxic material
  • Durable and long-lasting
  • Doesn’t impart any taste or odor into the water

Cons

  • Can stain if not cleaned properly after each use
  • Harder to find than other types of water bottles
  • Expensive compared to plastic or aluminum options
  • Limited color choices or designs available
