Do Unwashed Water Bottles Contain More Bacteria Than Toilet Seats?

A person holds up a stainless steel water bottle.

Cutting down on disposable water bottles by turning to a reusable water bottle is great and all, but are you guilty of not washing it? It’s so convenient to grab and go—and when you get back home after a long day, you tell yourself you were the only one using it. That means it’s basically clean… right?

Hmm… wrong. Turns out, if you wouldn’t lick a toilet seat, you shouldn’t drink out of a dirty water bottle.

Why a toilet seat specifically? Because according to a study conducted by WaterFilterGuru.com, your water bottle could be carrying up to 40,000 times more bacteria than the average toilet seat.

If you don't want to clean your water bottle every day, at least get one that does some cleaning for you.

But that’s not all. After carefully swabbing all these items three times (and different types of water bottles), the research shows that the average reusable water bottle has 14 times more bacteria than the average pet bowl, five times the bacteria found on the average computer mouse, and two times the bacteria found in a kitchen sink.

That’s super disgusting when you realize the kitchen sink is one of the germiest, bacteria-infested areas of a home (even worse than the toilet seat—surprise, surprise).

So, what can you do to avoid a bacteria-filled bottle? Wash it! Experts recommend cleaning your water bottle after every single use, even if it only contained water. You can easily accomplish this with hot water and soap, or putting it in the dishwasher if it’s dishwasher safe.

Don’t let your water bottle become a breeding ground for bacteria. Keep it clean and fresh, and stay hydrated the healthy way!
