Who is each format for?

Hosts of smaller children's parties

A single 2-litre bottle can cover a drinks-table top-up without opening a whole multipack. It gives 10 servings if you pour 200 ml into each cup; plan around the cups and refills you expect to use.

Hosts planning more refills

A 6 × 2-litre pack holds 12 litres, enough for 60 servings at 200 ml each. That format makes more sense if you expect to use the volume and have space to store unopened bottles and refrigerate any you open.

Shoppers choosing a particular brand

Check the bottle size as well as the name. Bestway Wholesale lists Highland Spring in 2 litres, and Tesco has listed a 2-litre Evian bottle. Volvic and Buxton show smaller sizes on their official UK still-water range pages, so check the exact product before counting on either for a 2-litre plan.

What should you check before buying?

Start with the drink you want to serve, calculate the volume from your cups and expected refills, then check how you will store and handle the bottles.

Priority What to check Your needs
Drink type Check that the product is plain still water if that is what you intend to serve. NHS guidance names water and milk as drinks for children and advises avoiding sugary fizzy drinks, squash and juice drinks. I want a straightforward water option for a group of children, without assuming that flavoured or fizzy drinks are interchangeable with it.
Total volume Multiply your planned cup size by the number of servings. A 2-litre bottle provides 10 servings at 200 ml each; six such bottles provide 12 litres, or 60 servings at that cup size. For a few refills, I may need only one bottle. If many guests are likely to return to the drinks table, I need to plan for the total volume rather than the bottle count alone.
Storage and caps Read the instructions on the bottle you buy. Tesco and Sainsbury's say to refrigerate their opened own-label bottles and use them within 3 days; Sainsbury's also warns that its bottle cap could be a choking hazard for small children. I need space for the bottles and a way to keep opened ones refrigerated. Loose caps also need to be kept away from young children.
Exact bottle size Confirm that a preferred product is 2 litres, not merely part of a still-water range. Volvic's and Buxton's official UK range pages display sizes up to 1.5 litres. If my serving plan depends on 2-litre bottles, I'll check the selected product's size before calculating how many to buy.

Party-water mistakes to avoid

  • Assuming a familiar brand has a 2-litre bottle

    Volvic's and Buxton's official UK still-water ranges display bottles up to 1.5 litres. Choosing by brand alone could leave your volume calculation based on the wrong size.

    Check the exact size on the product you plan to buy, then calculate the number of bottles from that size.

  • Counting bottles instead of servings

    One 2-litre bottle supplies 10 servings only if each serving is 200 ml. Different cup sizes change how far it will go.

    Choose a cup size, estimate the servings you expect to pour and calculate the total litres before deciding between a single bottle and a pack.

  • Opening the whole pack at once

    Tesco's and Sainsbury's own-label product instructions say to refrigerate opened bottles and use them within 3 days.

    Open bottles as the drinks table needs refilling, and follow the storage directions on the products you buy.

  • Leaving loose caps on the drinks table

    Sainsbury's warns that the cap on its 2-litre bottle could be a choking hazard for small children.

    Collect removed caps promptly and keep them out of young children's reach.

Brand and supermarket ranges

The named ranges differ in the bottle sizes shown, so compare the exact product rather than assuming every still water comes in 2 litres.

Sainsbury's

Sainsbury's lists still spring water as both a single 2-litre bottle and a 6 × 2-litre pack.

  • The pack holds 12 litres while keeping each bottle at 2 litres.
  • Its instructions say to refrigerate opened bottles and use them within 3 days; its bottle-cap warning matters around small children.

Tesco

Tesco lists an own-label 2-litre still natural mineral water bottle.

  • A single bottle is an option for a smaller serving plan or a top-up.
  • Tesco says to refrigerate it after opening and use it within 3 days.

Highland Spring

Bestway Wholesale lists Highland Spring still spring water in a 2-litre bottle.

  • The listed bottle matches an exact 2-litre serving plan.
  • The cited listing is wholesale-facing; check the bottle size and availability at the shop you intend to use.

Evian

Tesco has listed Evian natural mineral water in a 2-litre bottle.

  • The listed format meets a 2-litre bottle requirement.
  • Check availability before relying on it for a party.

Volvic

Volvic's official UK natural mineral water page displays 500 ml, 1-litre and 1.5-litre bottles.

  • Those displayed sizes give alternatives if an exact 2-litre bottle is not essential.
  • Confirm a 2-litre product separately before building a party plan around that size.

Buxton

Buxton's official UK still-water page displays 500 ml, 750 ml, 1-litre and 1.5-litre bottles.

  • The displayed sizes can be counted into a plan that allows smaller bottles.
  • Check the exact product if your plan requires 2-litre bottles.

Questions about serving and storing water

Is still water a sensible default for a children's party?

Plain still water is a straightforward option for a shared drinks table. NHS guidance names water and milk as drinks for children and advises avoiding sugary fizzy drinks, squash and juice drinks.

How many cups will a 2-litre bottle fill?

A 2-litre bottle fills 10 cups at 200 ml each. If you plan smaller or larger pours, divide 2 litres by your chosen cup volume instead; the calculation is for party planning, not an intake target.

What should I do with opened bottles after the party?

Follow the directions on the bottle you bought. Tesco's and Sainsbury's own-label 2-litre products say to refrigerate opened bottles and use them within 3 days; instructions for another product may differ.

Can I refill an empty party-water bottle?

Sainsbury's instructions for its 6 × 2-litre spring-water pack say not to refill those bottles for hygiene reasons. If you want a refillable serving vessel, use a clean reusable jug or bottle instead.
