Water helps the body regulate temperature, aid digestion, lubricate joints, transport nutrients to our cells, and prevent infection. Unfortunately, many of us aren’t drinking nearly enough.
When I decided to increase my own fluid intake, the first thing I did was buy a new water bottle. I've got myself a 18 oz Thermos Water Bottle and I love the flip lid and wide open chug chap. It’s a great water bottle and keeps my drinks cold all day long. I love drinking from it (when my kids don't steal it from me)
Depending on your fluid intake goals and the size of your bottle, the number of Thermos Water Bottles you should drink each day will vary. If you aim to drink the recommended eight cups per day, you’d need to finish four 16 oz bottles, two 32 oz bottles, or a single 64 oz bottle.
Below, I’ll show you how many Thermos Water Bottles or Tumblers you should drink each day, depending on your goal and the size of your bottle. I’ll also teach you how to determine how much water you should actually be drinking per day.
How Many Thermos Water Bottles Should You Be Drinking Per Day?
The number of Thermos Water Bottles you should drink per day depends on your own fluid intake goals and the size of your bottle.
Because I’m so active, I usually aim for eight cups of water per day and drink around 4 of my 18 oz Thermos bottles to reach my target.
My kids don’t need to drink nearly as much. When they steal my water bottle they only need to drink about 2 bottles worth to drink 4 cups a day.
Use the chart below to determine just how many Thermos bottles or tumblers you should drink each day to reach your own hydration goals.
| Thermos Bottle Size | 4 Cups/Day | 8 Cups/Day | 1 Gal/Day |
| 12 oz | 2.7 | 5.3 | 10.7 |
| 16 oz | 2 | 4 | 8 |
| 18 oz | 1.8 | 3.6 | 7.1 |
| 20 oz | 1.6 | 3.2 | 6.4 |
| 24 oz | 1.3 | 2.7 | 5.3 |
| 25 oz | 1.3 | 2.6 | 5.1 |
| 32 oz | 1 | 2 | 4 |
| 40 oz | 0.8 | 1.6 | 3.2 |
| 64 oz | 0.5 | 1 | 2 |
| 68 oz | 0.5 | 0.9 | 1.9 |
How Much Water Should You Be Drinking Per Day?
The amount of water you should drink each day varies significantly from person to person. Factors like your location, age, weight, activity level, and overall health all play a big role.
While it’s commonly stated that you need to drink eight glasses of water a day to stay hydrated, it’s really not that simple.
Eight cups is a reasonable target but may be too much for some and not nearly enough for others.
Healthcare Triage did a great job of breaking down the “eight glasses a day” myth in the video below.
According to The National Academies of Sciences, Engineering and Medicine, most people can meet their daily hydration needs by simply letting their thirst guide them.
It was found that, on average, well-hydrated women consumed around 91 oz of water each day and men 125 oz. Just keep in mind, that includes liquid from beverages as well as food — with about 20% coming from food and 80% coming from water and beverages – including caffeinated beverages (thank you coffee!)
Healthy adults who drink when they’re thirsty and drink more before, during, and after physical activity are well-hydrated more often than not.
