Raspberry Watermelon Water: Recipe & How to Make It

DetoxWater Editorial Team•Published November 5, 2026

Raspberry watermelon water is water infused with raspberries and watermelon; it takes 2 hours 10 minutes and makes about 4 cups (950 ml).

What is raspberry watermelon water?

Raspberry watermelon water is a chilled infusion made by letting fresh fruit steep in drinking water. The raspberries add a tart berry flavor, while the watermelon gives the water a mild, sweet aroma.

Unlike a blended drink, the fruit is left mostly intact and can be strained out before serving. It is one of many berry infused water recipes that rely on fruit for flavor rather than added sweetener.

What ingredients and ratio do you need?

Yield: About 4 cups (950 ml), or approximately 4 servings
Prep time: 10 minutes
Steep time: 2–4 hours, refrigerated
Total time: 2 hours 10 minutes with the shortest steep

Ingredients

  • 60 g raspberries, about 1/2 cup
  • 75 g watermelon flesh, cut into cubes, about 1/2 cup
  • 950 ml drinking water, about 4 cups

This ratio uses about 1 cup (135 g) of prepared fruit for 4 cups (950 ml) of water. Choose ripe, fragrant fruit for the most noticeable flavor. The drink will still taste primarily like water, with a gentle fruit infusion rather than the intensity of juice.

How do you make raspberry watermelon water?

  1. Rinse the raspberries gently under running water. Rinse the outside of the watermelon before cutting it.
  2. Cut the watermelon flesh into small cubes, discarding the rind and any hard seeds. Measure out the fruit for the recipe.
  3. Place the raspberries and watermelon in a clean pitcher or covered jar. Leave the raspberries whole for a clearer infusion.
  4. Pour in the drinking water, stir gently and cover the container.
  5. Refrigerate for 2–4 hours. Pour into glasses with the fruit, or strain it out before serving.

The shorter steep gives a lighter result; leave the pitcher refrigerated for the full 4 hours if you prefer a more developed flavor. Stir gently before pouring, since the fruit may float or settle as it rests.

Why do raspberry and watermelon pair well?

Raspberries bring a bright, tart note that balances watermelon’s mild sweetness. Watermelon’s softer flavor leaves room for the berries, so neither fruit needs to overpower the other. For a lighter berry taste, use a little less raspberry; for a more pronounced berry note, gently press a few berries against the side of the pitcher.

The main benefit of raspberry watermelon water is hydration. Whole raspberries and watermelon also contain nutrients, but the amount that passes into steeped water is uncertain; eating the fruit provides more of its fiber than drinking the strained infusion.

The liver and kidneys do most of the body’s detoxification, while the lungs and gut help eliminate waste. This drink supports hydration, not a special detox process. You can also explore raspberry infused water for its tart flavor or watermelon infused water for its mild sweetness.

How should you store raspberry watermelon water?

Keep raspberry watermelon water covered in the refrigerator and drink it within 24 hours for the best flavor. Return the pitcher to the refrigerator promptly after serving rather than leaving it at room temperature.

Discard the infusion after 2–3 days, or sooner if it becomes cloudy or slimy or develops a sour smell. Use a clean pitcher and freshly rinsed fruit each time you make a batch.

How can you vary raspberry watermelon water?

Add fresh mint

Add a small sprig of rinsed mint before chilling for a cool herbal note. Keep the fruit amounts the same so the raspberry and watermelon remain the main flavors.

Press some of the fruit

Gently press a few raspberries or watermelon cubes before adding the water for a stronger, cloudier infusion. Pressing releases more fruit into the drink than steeping it intact.

Serve with the fruit

Leave the fruit in the glass instead of straining it out. The watermelon makes a soft bite after steeping, and eating the fruit adds its calories and nutrients to what you consume.
