Water and Ice in Thailand: What's Safe to Drink and How to Avoid an Upset Stomach?
The Question Every Traveler Asks
Tap water in Thailand isn't safe to drink — that's a fact worth knowing clearly, not just 'being a bit careful'. But that doesn't mean you need to fear every drop of water — you just need to know the rules.
Bottled Water — the Simple Solution
Sealed bottled water is cheap and sold everywhere — 7-Eleven, supermarkets, restaurants. This is the safest, simplest way to drink, and you don't need to overthink it.
Ice — What's Really Important to Check
Industrial ice (round with a hole in the middle, factory-made) is usually safe — this is the common type at restaurants and hotels. Local ice with an unclear source (mainly at unknown street stalls) can be less reliable. At most tourist places and regular restaurants, ice is completely safe.
Brushing Teeth and Showering
Showering in tap water is completely safe — the risk is only in swallowing, not skin contact. Brushing teeth with tap water is usually considered safe (a tiny amount swallowed), but those especially sensitive can use bottled water for this too.
What to Do If an Upset Stomach Happens Anyway
Rest, plenty of fluids (water + salts, there are special powders sold at local pharmacies), and avoiding heavy food for a day or two. If symptoms are severe or last beyond 2-3 days, worth seeing a doctor — there are tourist clinics at all major destinations.
What About Vegetables and Food Washed in Water
Vegetables and fruit washed at proper restaurants (not a questionable street stall) are usually safe — businesses regularly serving tourists are aware of this sensitivity. In any case of doubt, you can ask to skip unpeeled fresh vegetables at unknown stalls.
Water at Hotels
Most hotels (even budget-level) provide free water bottles in the room, at least one or two a day — worth taking advantage of this and not buying water separately every time, especially at mid-range hotels and above.
A Reusable Bottle with a Filter
Long-term travelers or environmentally conscious ones sometimes consider a bottle with a built-in filter (like LifeStraw) — saves buying disposable plastic over time, though not essential for a short trip when bottled water is available and cheap everywhere.
Kids and Babies
The same rules apply to kids too, but with heightened sensitivity — worth being more careful with ice and non-bottled water for those with more sensitive digestive systems. Always bottled water for baby formula, not tap water.
