How Does Water Safety Work in Vietnam?
Last verified: 2025-06 · Asia
1The Quick Answer
Never drink tap water in Vietnam — stick to bottled water, which is widely available and very cheap.
2What You Need to Know
Tap water in Vietnam is not safe to drink due to ageing pipes and contamination risks. Bottled water (500ml) costs 5,000–10,000 VND at convenience stores and is available everywhere. Ice at tourist restaurants and hotels is generally made from purified water and is considered safe. Ice at roadside stalls and street vendors — particularly large block ice — should be avoided as it may be made from tap water.
3Practical Tips
Practical Tips
- 1Buy large 1.5-litre bottles from convenience stores like Circle K or Winmart for better value than individual small bottles.
- 2Brushing teeth with tap water is generally considered acceptable by most travellers, but use bottled water if you have a sensitive stomach.
- 3Carry a reusable bottle with a filter (e.g. LifeStraw) for environmental sustainability and backup water safety in rural areas.
