Pros and Cons of Glass 

Glass bottles are considered some of the safest bottles to drink from. Similar to stainless steel, they have their own advantages and disadvantages.


  • Glass keeps the taste of your water in its pure form. It does not have any metal parts. It can save you from any metallic taste.
  • Glass does not leach any chemicals into your water as well. It does not require any lining which makes it safer than other water bottles such as aluminum.
  • Glass bottles can be washed in the dishwasher. High-quality glass bottles will not undergo any wear and tear. Yet they can be easily broken if you accidentally drop them.
  • Glass is highly sustainable. Although it is expensive, if you use it carefully, you can use it for many years.


  • Glass bottles do not have any insulation so they cannot keep the temperature of your drinks for hours, as opposed to stainless steel bottles.
  • Glass is easily breakable which gives it a shorter lifespan than stainless steel.
  • Some public places do not allow glassware.
  • Glass can be heavier than a stainless steel water bottle with or without content.

What About Plastic Water Bottles?

Granted, plastic is lightweight, durable, and extremely cheap. That’s why it’s one of the most used materials for water bottles. However, plastic can transfer not only a certain taste or odor to your water when you drink, but it can also leach harmful chemicals that end up in your body

More importantly, even if you wash and reuse plastic bottles, you’re still contributing to the ever growing single-use plastic litter that’s harmful to the environment. Single-use plastics are an important factor in driving climate change and plastic water bottles are one of the largest contributors to these litter issues.

Finally, plastic is not a good material when it comes to keeping water (or any other drink) hot or cold for a long time, usually, because these water bottles are not insulated.
