Kiwi summers are getting hotter. While we're out there making the most of it with beach days, backyard cricket, endless BBQs, our bodies are quietly working overtime to stay cool.

The problem? Most of us aren't drinking nearly enough water to keep up.

Between the kids tearing around on school holidays, gardening in the midday heat, and those sticky nights when sleep feels impossible, your water needs spike. But knowing exactly how much you need (and actually drinking it) are two very different things.

A Just Water home water cooler takes the guesswork out of staying hydrated and makes it effortless for the whole family

How Much Water Should You Actually Drink During Summer?

You've probably heard the standard advice for adults: 1.5 to 2 litres a day. But during a New Zealand summer, that's not enough for most people.

On a warm day, it’s better for adults to aim for 2.5 to 3 litres to stay properly hydrated.

You'll need even more water if you're spending time outdoors, exercising, or drinking coffee and alcohol, all of which dehydrate you faster than you realise. And if you're feeling tired, lightheaded, or just a bit off? That's often your body asking for water.

The challenge is remembering to drink consistently throughout the day. That's where having chilled, great-tasting water always within reach makes all the difference.

Why a Home Water Cooler Is a Summer Game-Changer

💧 Cold Water, Instantly

When it's hot, everyone wants cold water, not lukewarm tap water or waiting for the jug in the fridge to chill. A Just Water cooler delivers instant chilled water whenever you need it, whether you're coming in from the garden or the kids are asking for their fifth drink of the afternoon.

💧 Your Family Will Actually Drink More

Here's the thing: when water is easy to access and cold, people drink more of it. Kids especially. A home water cooler sitting in the kitchen becomes a natural reminder to stay hydrated, no nagging required.

💧 Water That Actually Tastes Good

During summer, tap water may be slightly warm. Just Water coolers use filtration to improve the taste, making every glass crisp, clean, and refreshing. When water tastes better, you drink more of it. It's that simple.

💧 Affordable for Every Household

Just Water home cooler rentals start from as little as $1 per day. No more filling ice trays. No more cluttering your fridge with big jugs. No more warm water pretending to be refreshing. Just chilled, filtered water on tap for less than your daily coffee.

Choose the System That Suits Your Home

Fill-Your-Own Home Water Cooler (Most Popular)

This option comes with a filter kit that attaches directly to your tap, letting you fill the reusable bottle (also supplied) whenever you need it. Simply pop the filled bottle onto your water cooler and enjoy unlimited chilled, great-tasting water all summer long.
