Can You Drink the Tap Water in Thailand?
QUICK ANSWER
No, tap water in Thailand is not safe to drink, so stick to bottled or filtered water and avoid non-purified ice. Thailand uses the baht. Watch the outlets: US-shape plugs fit but run on 220 volts, which can damage US-only devices. Tipping is appreciated but not traditionally required.
Thailand is a fantastic, easy destination, but the tap water and a plug detail are the two things to get right. Here is what you need to know about the water, currency, tipping, and power adapters before you land in Bangkok or the islands.
Can you drink the tap water in Thailand?
No, tap water in Thailand is not recommended for drinking. While the water is treated and may leave the plant safe, the pipes and storage tanks can introduce contaminants, and visitors' stomachs are not adapted to local microbes, so tap water commonly causes travelers' illness. Stick to bottled or filtered water for drinking, which is cheap and available everywhere, and use it for brushing your teeth if you have a sensitive stomach. Ice at reputable hotels and restaurants is usually made from purified water and generally fine, but be cautious with ice and drinks from very basic street stalls. Sticking to bottled water is the simple precaution that protects your trip.
What currency is used in Thailand?
Thailand uses the Thai baht (THB), shown with a symbol resembling a B with a vertical line. Thailand is fairly cash-based, especially for street food, markets, tuk-tuks, and small vendors, so carry baht for daily spending, ideally in a mix of small notes. Cards are accepted at hotels, malls, and larger restaurants in cities and tourist areas. Withdraw baht from an ATM for a fair rate, though note that Thai ATMs charge a fixed foreign-card fee per withdrawal, so taking out larger amounts less often reduces fees. Choose to be charged in baht rather than dollars, and use a card with no foreign transaction fees where possible.
Do you tip in Thailand?
Tipping in Thailand is not deeply traditional but is increasingly appreciated, especially in tourist areas, and amounts are small. In restaurants, leaving the loose change or rounding up is common, and around 10 percent for good service in a nicer restaurant is welcomed, though check the bill, since upscale places may add a service charge. Tip massage therapists, hotel staff, and helpful guides small amounts, and it is polite to leave a little for good service generally. You do not need to tip for street food or a quick meal. A modest tip is a kind gesture rather than an obligation, and small notes make it easy to leave one.
What power adapter do you need for Thailand?
Thailand is a place to watch the voltage carefully. Outlets commonly accept Type A and Type C plugs, and some the Thai Type O, and many sockets take the US-style flat pins, but the electricity runs at 220 volts, nearly double the US 120 volts. So a US plug will often fit physically, yet plugging in a single-voltage US appliance like a hair dryer can destroy it or be dangerous. Always confirm your devices accept 220-volt input; phone and laptop chargers are almost always dual voltage and fine with just an adapter, but check anything else and use a converter for single-voltage items. Do not assume a device is safe just because the plug fits.
No, tap water in Thailand is not safe to drink, so stick to bottled or filtered water and be cautious with ice from basic stalls. Thailand uses the baht and is fairly cash-based. Crucially, US-shape plugs fit but run on 220 volts, so check every device, and tipping is appreciated in small amounts though not traditionally required.
