The answer is a big “No.”

You shouldn’t drink tap water in Thailand. This applies to all types of accommodations, from the cheapest to 5-star hotels. Tap water may contain:

  • Germs – pathogens and disease-causing bacteria
  • Heavy metals
  • Debris from aging pipes (old and corroded)
  • General dirt and impurities

Safety

Tap water is generally safe for the following uses:

  • Teeth brushing: You can use tap water for brushing your teeth for short or long durations. Small leftover amounts are not usually dangerous, but:
    • Do not intentionally swallow the water
    • If you have a very sensitive stomach, it is better to use bottled water
    • Take extra care when children are brushing their teeth
  • Washing: You can wash clothes and clean floors or other items with tap water
  • Showering: It is safe to shower and wash your body with tap water
  • Boiling water: Boiling kills most bacteria, but it does not remove debris or heavy metals. Therefore, it is still not considered safely drinkable

General Discussion

  • Most hotels in Thailand provide 2 free bottles of sealed drinking water per day
  • Many hotels have installed filtration systems, allowing guests to refill water free of cost
  • Always use bottled water for making tea or coffee instead of tap water, especially in hostels
  • You can use the silver “water refill” machines found on street corners for drinking water; these are generally safe and inexpensive

Accidental Drink

Do not panic. An accidental sip or small gulp is highly unlikely to cause major or immediate harm.

However, if symptoms of gastroenteritis such as nausea, vomiting, or abdominal cramps occur, consult a doctor immediately.

Tip

Be more careful in small villages or remote island areas, where water quality is often poorer than in major cities.
