You’re standing at the hotel sink in Rome, toothbrush in hand, and the question hits you: is tap water safe in Europe? Can I actually drink this? Should I be buying bottled water for everything? You’ve heard vague warnings from a coworker who “got sick in Barcelona once,” and now you’re second-guessing something as basic as hydrating.
Take a breath. The short answer is that tap water in most of Europe is not only safe — it’s often better regulated than what comes out of your faucet at home. The EU has some of the strictest drinking water standards in the world, and many European cities have been delivering clean water for centuries. Literally. Rome’s been at it since the aqueducts.
But there are nuances. Some countries outside Europe are a different story entirely. And there are a few local customs around water that’ll save you money and confusion if you know them ahead of time.
This guide covers the major countries Americans visit — across Europe and beyond — so you can stop Googling “can you drink tap water in Italy” at 2 AM and actually get some sleep before your trip.
Convierge gives you destination-specific safety tips, including water advisories, right in the app. Check out the local intel features and travel with confidence instead of anxiety.
Let’s be direct. If you’re visiting Western or Central Europe — the UK, France, Italy, Spain, Germany, Portugal, the Netherlands, Austria, Switzerland, the Nordics — the tap water is safe to drink. Full stop.
The European Union’s Drinking Water Directive sets rigorous standards that member states must meet. In many cases, European tap water undergoes more frequent testing than US municipal water. Germany, for example, tests its tap water against over 50 quality parameters, and the compliance rate is above 99%. Austria’s water comes largely from Alpine springs and is genuinely some of the best-tasting water you’ll find anywhere on the planet.
So why do so many Americans worry about this? A few reasons. One, we conflate “Europe” with “abroad,” and “abroad” triggers a vague sense that everything is less safe. Two, we see Europeans drinking bottled water constantly and assume the tap water must be bad. (It’s not — it’s a cultural preference, and often a status thing.) Three, someone always has a friend-of-a-friend story about getting sick overseas, and it gets attributed to the water when it was almost certainly the third glass of wine on an empty stomach.
The real risk factors for getting sick abroad are the same as at home: undercooked food, poor hand hygiene, and overdoing it. The water is almost never the culprit in Western Europe.
If this is your first time heading across the Atlantic, pair this guide with our first-timer’s travel checklist so water safety is just one box you’ve already checked.
Here’s the breakdown for the countries Americans visit most. No hedging, no “it depends.” Just clear answers.
| Country | Tap Water Safe? | Notes |
|---|---|---|
| United Kingdom | Yes | Safe everywhere. Tastes different from US water — slightly more mineral-heavy in London, softer up north. You’ll adjust in a day. |
| France | Yes | Safe and well-regulated. At restaurants, ask for “une carafe d’eau” and you’ll get free tap water. Don’t let them push a €7 bottle of Evian on you. |
| Italy | Yes | Safe throughout the country. Rome’s public fountains (nasoni) are a highlight — more on those below. |
| Spain | Yes | Safe in cities and major tourist areas. Some coastal and rural areas have mineral-heavy water that tastes off but is still safe. Locals in those areas prefer bottled out of taste preference, not safety. |
| Germany | Yes | Excellent quality. Among the most rigorously tested water supplies in the world. Germans do love their sparkling water (Sprudel), but the tap stuff is perfectly fine. |
| Portugal | Yes | Safe in Lisbon, Porto, and other cities. Some older rural areas have pipes that affect taste, so locals sometimes prefer bottled. But it’s safe to drink everywhere. |
A few patterns worth noting. Every country on this list meets or exceeds the EU Drinking Water Directive standards (the UK maintained equivalent standards post-Brexit). In all of these countries, you can brush your teeth with tap water, make coffee with it, and drink it straight from the faucet without a second thought.
The taste will vary. London water has more calcium and magnesium than what you’re used to in, say, the Pacific Northwest. Barcelona’s tap water is famously not delicious — it’s safe, but it has a distinct mineral taste that makes locals reach for bottles. If taste is an issue, a filtered water bottle solves the problem without the environmental guilt of buying plastic.
One more thing: if you’re dining out in France and they bring you bottled water without asking, you didn’t order it — but you’re about to pay for it. The phrase “une carafe d’eau, s’il vous plaît” is your best friend. It gets you a pitcher of free tap water, and no one will judge you for it. Planning a trip to France? Our guide to traveling in Europe as an American covers dozens of these small customs that save you money and embarrassment.

Your trip might not stop at Europe’s borders. Here’s the quick take on four other popular destinations for American travelers, because the rules change significantly once you leave the EU.
This is the big one. Do not drink tap water in Mexico. The water treatment infrastructure varies enormously by region, and even in major cities like Mexico City, Cancun, and Guadalajara, the tap water is not considered safe for visitors. Locals have adapted over years of exposure, but your gut hasn’t.
Stick to agua embotellada (bottled water). Make sure the seal is intact when you buy it. Use bottled water for brushing your teeth. And be cautious about ice — more on that below.
This isn’t fear-mongering. It’s just the reality of the infrastructure right now. Mexico has incredible food, culture, and hospitality. The water situation is a minor inconvenience, not a reason to skip the trip.
Same deal as Mexico. Tap water in Thailand is not safe to drink. Bangkok, Chiang Mai, the islands — bottled water everywhere. The good news: bottled water in Thailand is absurdly cheap. You’ll pay 7-10 baht (about 20-30 cents) for a bottle at any convenience store, and your hotel will usually provide a couple of complimentary bottles daily.
When ordering water, “nam kuat” means bottled water in Thai. At sit-down restaurants in tourist areas, the water and ice served are typically safe (made from purified water). Street food stalls are where you want to be more careful — more on ice below.
Japan’s tap water is safe, clean, and honestly exceptional. The water treatment standards in Japan are among the highest in the world, and you can drink from the tap anywhere in the country — Tokyo, Osaka, Kyoto, rural areas, everywhere.
Japan also has vending machines approximately every 30 feet (slight exaggeration, but barely), so you’ll never be far from water regardless. But there’s no health reason to avoid the tap. For everything else you need to know before heading to Japan, check out our complete Japan travel guide.
Australia’s tap water is safe and well-regulated across the country. Sydney, Melbourne, Brisbane, Perth — drink up. The water quality in most Australian cities is comparable to or better than major US cities. Some remote outback areas rely on bore water or tank water that might taste different, but even that is generally safe.
Two questions that come up constantly: Can I drink from public fountains? And is the ice safe?
In countries where tap water is safe, public drinking fountains are also safe. They’re fed by the same municipal water supply. Rome’s nasoni — those small cast-iron fountains scattered throughout the city — are one of the best things about visiting. There are over 2,500 of them, they run continuously with fresh, cold water from the same aqueduct-fed supply that serves the city, and they’ve been keeping Romans hydrated for over a century. Cover the spout with your finger and water shoots up from a small hole on top, making it easy to drink without putting your mouth on anything.
You’ll find public fountains throughout Italy, France, Germany, and most of Western Europe. If the fountain has a sign that says “acqua non potabile” (Italy), “eau non potable” (France), or “kein Trinkwasser” (Germany), that means it’s NOT for drinking — it’s decorative or for washing. No sign? You’re good.
Here’s the simple rule: if the tap water is safe, the ice is safe. Restaurants in Europe make their ice from the same tap water you’d drink from the faucet. There’s no separate, sketchy ice supply chain.
In countries where tap water is NOT safe (Mexico, Thailand), ice becomes a judgment call. At established restaurants and hotels, ice is almost always made from purified water. At street food stalls, it’s a coin flip. The generally safe move is to skip ice at smaller, informal spots and accept it at proper restaurants. If you want to be extra cautious, just drink your beverages without ice — nobody will look at you funny.
And yes, before you ask: brushing your teeth with tap water is perfectly fine in any country where the tap water is safe to drink. You’re using a tiny amount, and it’s the same water supply. In Mexico and Thailand, use bottled water for brushing, but in Europe, your hotel bathroom sink is totally fine.
For Mexico, Thailand, and other destinations where tap water isn’t safe, here are the practical moves that experienced travelers rely on.
Stock up daily. Buy a few large bottles of water each morning from a convenience store or supermarket. It’s dramatically cheaper than buying individual bottles from tourist spots throughout the day. In Mexico, look for garrafones (5-gallon jugs) at your rental — many Airbnb hosts provide them with a dispenser.
Learn the phrase. In Mexico, ask for “agua embotellada” or “agua purificada.” In Thailand, “nam kuat” gets you bottled water. In both countries, servers at tourist-facing restaurants will default to bottled water, but it never hurts to confirm.
Check the seal. This matters more in some regions than others, but it’s a good habit. Make sure the cap on your bottled water hasn’t been opened and refilled. A properly sealed bottle will have a plastic ring that snaps when you first open it.
Consider a filtered bottle. If you’re traveling through multiple countries with different water situations, a bottle with a built-in filter (like a LifeStraw or Grayl) gives you peace of mind everywhere. It won’t replace caution in places like rural Mexico, but it’s a solid backup.
Skip ice at street stalls. We covered this above, but it bears repeating. Sit-down restaurants in tourist areas? The ice is almost certainly purified. The cart selling fresh-squeezed juice on the side of the road? Maybe skip the ice. The juice itself is worth trying — just ask for it without ice.
Don’t forget the salad. In countries where you can’t drink the tap water, raw vegetables washed in that water carry the same risk. At established restaurants, produce is typically washed in purified water. At market stalls, you’re rolling the dice. Cooked food is always the safer bet if your stomach is sensitive.
For the vast majority of American travelers visiting Europe, tap water is a non-issue. Drink it from the faucet, drink it from public fountains, use it to brush your teeth, and stop buying overpriced plastic bottles. Your wallet and the planet will thank you.
For Mexico and Thailand, switch to bottled and take the basic precautions above. It’s a minor adjustment that becomes second nature by day two.
