The Short Answer: Don’t Drink the Tap Water

Let’s cut to the chase: No, it’s not recommended to drink tap water in Cancún.

While the water in Cancún technically goes through a purification process at the municipal level, the infrastructure—especially in older buildings or small establishments—can be unreliable.

Pipes may be outdated, and bacteria can still make their way into the supply before the water even reaches your glass.

Locals often boil their water, use filtration systems, or drink bottled water themselves.

And if they don’t drink it straight from the tap, you probably shouldn’t either.

The risks? Upset stomach, diarrhea, or worse—none of which pair well with beach lounging or snorkeling.

Why Is Tap Water Unsafe in Cancún?

The water treatment facilities in Cancún do their part, but the problem lies in the distribution system.

Old pipes, potential contamination during storage, and even small leaks in underground lines can introduce harmful microorganisms such as E. coli or parasites.

Additionally, many hotels and restaurants don’t rely on the municipal supply alone.

They often use private water tanks, and if these aren’t cleaned regularly, they can become breeding grounds for bacteria.

In short: the water might be safe when it leaves the treatment plant—but it may not be by the time it reaches your hotel faucet.

What About Ice, Fruits, and Salads?

This is where things get a bit tricky. You might be avoiding the tap, but what about that delicious frozen daiquiri or the refreshing cucumber salad?

Here’s the good news: Most tourist-friendly places—especially resorts, hotels, and well-rated restaurants—use purified or filtered water to make ice, wash produce, and prepare food. In fact, many of them go out of their way to ensure hygiene to meet international standards.

That said, street food vendors or very low-budget eateries might not follow the same precautions. If you're unsure, ask if purified water is used, or stick to cooked foods and peeled fruits.

Bottled Water Is Your Best Friend

In Cancún, bottled water isn’t just a convenience—it’s a must. Thankfully, it’s widely available, very affordable, and comes in multiple sizes.

Popular brands like Bonafont, Ciel, and Epura are safe and easy to find at any convenience store, supermarket, or hotel. A 1.5-liter bottle typically costs less than $1 USD.

Most hotels offer complimentary bottled water in your room, and you’ll often find large water dispensers in lobbies or lounges for refills.

Tip: Always carry a bottle with you when you head out for tours, beach walks, or excursions. The sun in Cancún is strong, and hydration is key!

Can I Brush My Teeth with Tap Water?

This one causes a lot of debate among travelers, but here’s a general rule:

  • Locals do it without issues (their bodies are used to the water).
  • Tourists might get sick from even small amounts if they have sensitive stomachs.

If you want to play it safe, use bottled water to brush your teeth. It might feel a little over-the-top at first, but many travelers swear by it after learning the hard way.

Also, try to keep your mouth closed when showering and don’t swallow any water, especially if you're staying at a small hotel or Airbnb.

What About Resorts and All-Inclusive Hotels?

Good news: Most resorts in Cancún go the extra mile when it comes to water safety.

They often have their own purification systems, provide free bottled water to guests, and use filtered water for food preparation, ice, and beverages.

In fact, it’s one of the reasons people feel so comfortable staying in all-inclusive properties—they know the basics are covered.

Still, it’s smart to double-check with the front desk and keep a bottle of water nearby just in case.

Can You Cook with Tap Water in Cancún?

If you're staying in a vacation rental or Airbnb with a kitchen, you might be tempted to cook using tap water.

For tasks like boiling pasta or steaming vegetables, the high heat will usually kill any bacteria—so it’s generally okay.

However, for rinsing produce, making ice, or mixing drinks, stick to purified or bottled water.

And always wash your hands with soap and dry them thoroughly if you’ve been using local tap water.

Pro Tips to Stay Safe and Hydrated

  • Always ask if ice is made with purified water when ordering drinks.
  • Carry electrolyte packets just in case of mild stomach upset or dehydration.
  • Don’t reuse plastic bottles more than once unless you’re refilling from a trusted filtered source.
  • Stay hydrated—especially under the hot Caribbean sun. Dehydration happens fast in Cancún!

Enjoy Cancún Without Worry

Cancún is one of the most stunning destinations in the world, and with just a few simple precautions, you can enjoy every moment of your trip without worrying about water issues.

Stick to bottled water, ask questions when in doubt, and listen to your body.

Trust us—nothing ruins a vacation faster than a stomach bug, and staying hydrated with clean water is one of the easiest ways to stay healthy.

So go ahead—book that flight, pack your bags, and say yes to adventure. Just don’t forget the bottled water!
