How Many Bottled Water Should I Drink a Day?

It seems like a simple question: how much water should you drink each day? But between fitness fads, health blogs, and confusing advice, most people are left guessing. The truth is, hydration isn't one-size-fits-all—and bottled water may not be the smartest way to meet your daily needs.

While the classic "8 glasses a day" rule is a decent benchmark, the real answer depends on your body size, activity level, climate, and even your diet. Athletes, travelers, and outdoor adventurers often need more, while someone working indoors all day might need less. The UK's NHS recommends drinking 6 to 8 cups or glasses of fluids a day, which is roughly 1.5 to 2 litres. This includes water, lower-fat milk, and sugar-free drinks.

How Many Bottled Water Should I Drink a Day?

Let’s break it down. A standard bottled water is around 500ml (16.9 oz). To meet the NHS guideline, that’s roughly 3 to 4 bottles a day. But that adds up—not just for your wallet, but for the environment. In the UK, around 7.7 billion plastic water bottles are used each year, and many of them don’t get recycled.

The Hidden Costs of Bottled Water.

Beyond the environmental toll, there are safety and trust issues. Some bottled water brands have faced scrutiny over microplastics and questionable sourcing. And if you’re relying on bottled water while commuting, traveling, or hiking, carrying multiple bottles daily is anything but convenient.
