Cucumber Water Calories and Nutrition Facts

DetoxWater Editorial Team•Published November 2, 2026

A 250 ml (about 1 cup) glass of unsweetened, strained cucumber water usually contains 0 to fewer than 10 calories (kcal). The amount of cucumber, steeping time, whether you squeeze or eat the slices, and any sweeteners can change the count. Use the ai nutrition analyzer to estimate calories from ingredients, but recognize that the amount transferred into infused water is uncertain.

How many calories are in cucumber water?

Plain cucumber water gets its calories from substances that move out of the cucumber during steeping. The under-10-kcal figure is a general guide for a glass of steeped infused water, not a laboratory measurement of every cucumber water recipe.

Water itself has no calories, and raw cucumber is low in calories. A 2013 review of cucumber describes the vegetable as water-rich and low in calories, but it does not measure the nutrition of cucumber water.

If you strain out the slices, you do not consume all the calories in the cucumber used to make the drink. Eating the slices adds their remaining calories; blending the cucumber into the water makes the whole cucumber part of the drink. Squeezing the cucumber or adding sugar, honey or another caloric ingredient can also increase the total.

For food safety, wash the cucumber, steep the water in the refrigerator for 2–4 hours and keep it refrigerated. Drink it within 24 hours for best flavor, and discard it after 2–3 days or sooner if it becomes cloudy, slimy or sour-smelling.

What are the nutrition facts per 250 ml?

There is no measured USDA FoodData Central entry for this particular cucumber water infusion in the data provided. The table instead uses USDA values for raw cucumber with peel to show what the cucumber contributes if you consume the slices as well as the water. The strained-water figures cannot be calculated precisely from those whole-cucumber values.

For the example, add 150 g of cucumber to 1 litre of water, then divide the water and cucumber evenly into four portions. Each portion has about 250 ml of water and 37.5 g of cucumber. The calculated column counts the cucumber nutrients in the water and slices together, without counting transferred nutrients twice.

NutrientPer 250 ml strained cucumber waterPer portion, including slices
CaloriesUsually under 10 kcalAbout 5.6 kcal
CarbohydratesNot measured1.36 g
SugarsNot measured0.63 g
FiberNot measured0.19 g
ProteinNot measured0.24 g
FatNot measured0.04 g
PotassiumNot measured55 mg
Vitamin CNot measured1.1 mg
SodiumNot measured0.75 mg

The calculated values come from USDA FoodData Central’s “Cucumber, with peel, raw” entry, FDC ID 168409. They are estimates based on the cucumber added, not USDA measurements of the finished drink. They also exclude any minerals already present in the water.

If you discard the slices, the drink contains only the portion of their nutrients that transferred into the water. A longer steep or more cucumber may change that amount, but the available data cannot say exactly how much.

How does cucumber water compare with juice and soda?

DrinkCalories and sugar
Unsweetened, strained cucumber waterUsually under 10 kcal per glass; the exact amount is not measured.
100% fruit juiceContains naturally occurring fruit sugars; calories vary by juice and serving size.
Regular sodaContains added sugar; calories vary by product and serving size.
Diet or zero-sugar sodaTypically has zero or few calories; check the label.

For a useful comparison, check labels for the same serving volume. Sugar provides about 4 kcal per gram, so a drink listing 20 g of sugar in a 250 ml serving has about 80 kcal from that sugar alone. Other ingredients can contribute calories too.

Unsweetened cucumber water can be a lower-calorie alternative to a sugary drink, but it is not a special detox treatment. It supports hydration; the liver and kidneys do most of the body’s detoxification, while the lungs and gut help eliminate waste.

Frequently asked questions

Does cucumber peel change the calorie estimate?

The USDA calculation above uses raw cucumber with the peel. Peeled cucumber has different nutritional values, so that calculation may not apply exactly.

Does cucumber water count toward fluid intake?

Yes. Unsweetened cucumber water is mostly water and can contribute to your daily fluid intake.

Can steeping cucumber longer increase the calories in the water?

Steeping time can affect how much transfers from the cucumber into the water, but the available data do not establish an exact calorie change. Keep the infusion refrigerated and follow the storage guidance.
