If the tap water isn’t safe, what should you do?

  • Buy sealed bottled water and check the seal is intact — it is cheap and available almost everywhere.
  • Boil it for one minute (three minutes at high altitude) if you have no bottled water; this kills the microbes that cause traveller’s stomach upsets.
  • Filter or purify with a reusable filter bottle or purification tablets — kinder to your budget and to the environment than buying plastic daily.
  • Watch the small stuff: ice, salad rinsed in tap water, and brushing your teeth can all catch you out in higher-risk countries. In cities, ice in reputable cafes is usually made from purified water.

A note on this guide: this is general travel guidance compiled from public-health sources, not medical advice. Water quality varies within a country and changes over time, and local boil-water notices can be issued at any time. When in doubt, choose sealed bottled or properly boiled/filtered water. If you are pregnant, travelling with young children, or have a weakened immune system, err toward bottled and speak to a travel-health professional before you go.

Tap water FAQ

Can you drink tap water in hotels?

In tap-safe countries, hotel tap water is fine. In higher-risk countries, hotel taps carry the same supply as everywhere else, so use the bottled water most hotels provide, unless the hotel states its water is filtered.

Is it safe to drink tap water if you boil it?

Yes — a rolling boil for about one minute (three at altitude) kills the bacteria, viruses and parasites behind most travellers’ stomach upsets. It does not remove chemical contamination, but for typical travel that is rarely the concern.

What happens if you accidentally drink tap water in a high-risk country?

Often nothing, but you may get a stomach upset (‘traveller’s diarrhoea’) within a day or two. Stay hydrated with sealed bottled water or oral-rehydration salts; most cases pass in a few days. See a doctor if symptoms are severe or persistent.

Can you brush your teeth with tap water?

In tap-safe countries, yes. In higher-risk countries it is safer to use bottled water and keep your mouth closed in the shower, as even small amounts can occasionally cause problems.

Is bottled water always safer?

Usually, but check the seal is intact — refilled bottles are a known scam in a few destinations. A good travel filter bottle is often safer, cheaper and greener than buying bottled all day.
