Tap water, ice and drinks in Indonesia
You are about to pick a drink at a roadside stall and want to know what is fine.
IndonesiaQuest Editorial · Updated 20 October 2026
Use sealed bottled water for drinking and brushing your teeth in Indonesia, and treat tap water as something for washing only. Ice follows the same logic as any other drink: ask where it came from, and choose busy places. A few simple habits keep your holiday on schedule.
Why bottled water is the easy choice
The US Centers for Disease Control and Prevention (CDC) says water can look clean and still carry bacteria, viruses and parasites, and it names factory-sealed bottled water as the lowest-risk choice for travellers [1]. That is the logic behind a bottle in your hand at every outing.
Check that the seal is intact before you drink. Hotels commonly provide complimentary bottles, and shops sell more at small cost.
What should I do about ice?
The same CDC page warns that contaminated water used to make ice can make you sick, so ice should be treated like any other drink [2]. That is a reasonable rule at a roadside stall as well as in a hotel bar.
At a busy restaurant, ask staff where the ice comes from. At a small stall, ask for your drink without ice. Our guide to street food hygiene for sensitive stomachs explains how to judge a stall.
Which drinks suit which situation?
| Drink | What to do | Good for |
|---|---|---|
| Sealed bottled water | Check the seal | Everyone |
| Hot tea and coffee | Order freshly made | Adults, older children |
| Sealed boxed juice | Choose for children | Young children |
| Fresh juice | Ask about the water and ice | Adults who are comfortable |
| Drinks with ice | Ask where the ice came from | Busy tourist-area venues |

Boiling is the best way to kill disease-causing organisms, and the CDC advises a full rolling boil for 1 minute, with the water cooled before use [3]. A kettle in a villa or serviced apartment makes this practical.
Check what the room provides, because hotel facilities vary. Our note on hotel wifi, hot water and air-con covers other in-room checks.
What routine works in a hotel room?
- Keep sealed bottles by the sink for brushing teeth.
- Ask reception where filtered refill water is available.
- Close your mouth in the shower, and keep children’s baths short.
- Rinse toothbrushes with bottled water.
- Carry a small bottle in your day bag.
For children, pack rehydration sachets and plain biscuits in case a stomach is upset.
Who is this best suited to, and when are other options better?
These habits suit first-timers, families and older travellers who want a plain routine. Better options for a very sensitive stomach are hotel restaurants and venues that serve sealed drinks, and a licensed agency can build those into your day.

Questions Malaysians ask
Can I drink tap water in Indonesia?
Plan to treat tap water as undrinkable and use sealed bottled water instead. Water can look clean and still carry bacteria, viruses and parasites. Use sealed bottles for drinking and for brushing teeth, and ask your hotel where refill water is available.
Is ice in drinks fine in Indonesia?
It depends on the source, so treat ice like any other drink. You cannot see where ice came from, so ask the staff. At small stalls, ask for no ice, and choose busy places in tourist areas.
Are fresh juices and coffee fine for children?
Hot coffee and tea are boiled, which helps, but fresh juice depends on the water and ice used. For children, choose sealed boxed juice, hot drinks cooled down, or fruit that you peel yourself. Ask staff whether juice is made with bottled water.
What if my stomach is upset?
Rest, sip sealed bottled water regularly, and eat plain food such as rice or toast. Rehydration sachets from a pharmacy help if you feel drained. If symptoms last, or a child or elderly parent has a fever or blood in stools, see a doctor promptly.
