How Many S’Well Bottles Should I Drink Per Day?

S’Well Water Bottles do a great job of keeping water ice cold for up to 36 hours, thanks to a clever triple-insulated, vacuum-sealing design.

When I got my S’Well bottle, I realized that I was unintentionally drinking a lot more water than ever before — which also led me to wonder exactly how many S’Well bottles I should aim to drink each day. 

If your goal is to drink eight cups of water per day, you’ll need to drink four 16 oz S’Well bottles, about two-and-a-half 25 oz bottles, or a single 64 oz bottle each day. Just keep in mind, the exact amount of water each person needs to stay hydrated can vary substantially based on age, health, location, and activity level. 

In my case, I had the 16 oz. bottle and my goal was to drink about a gallon of water per day (I’m pretty active so I need more than the average person). That meant that I needed to drink around eight bottles a day. 

Below I’ll show you how many S’Well bottles you should drink each day, depending on the size of your bottle and your specific goals. I’ll also teach you why you may not actually need as much water as you may think (though it’s better to err on the side of too much than too little). 

How Many S’Well Water Bottles Should You Be Drinking Per Day?

The number of S’Well water bottles you should drink each day depends on your target intake and the size of your bottle.

If you’re unsure how much water you should aim to drink, 8 cups per day is a safe baseline target (more on that below).

Use the following table to determine exactly how many S’Well bottles you’ll need to drink each day to reach your goal.

S’Well Bottle Size	4 Cups/Day	8 Cups/Day	1 Gal/Day
9 oz.	3.5	7	14.2
16 oz.	2	4	8
17 oz.	1.9	3.8	7.5
20 oz.	1.6	3.2	6.4
25 oz.	1.3	2.6	5.1
40 oz.	0.8	1.6	3.2
64 oz.	0.5	1	2

How Much Water Should You Be Drinking Per Day?

You’ve probably heard that you should be drinking 8 cups of water per day. While that’s a decent rule of thumb, it doesn’t really tell the whole story. 

In reality, the answer depends on quite a few different factors — including how active you are, where you live, your age, and your overall health.

Healthcare Triage did a great job of breaking down the “8 glasses of water a day” myth in the video below. 

Some days when I'm just working from home and not doing a lot I'll drink a lot less than 8 glasses of water per day.

Other days spent working out, at the beach or in the sauna I'll drink way more than 8 glasses of water per day. Always listen to your body.

Ultimately, drinking when you’re thirsty and aiming to have colorless or light yellow urine is more than good enough for a majority of healthy adults.
