Travel Question

    Can You Drink Tap Water in Rio?

    The tap water in Rio is technically treated and safe according to local standards, but we recommend drinking filtered or bottled water. Most Brazilians—including locals in Rio—drink filtered water at home and buy bottled water when out. Visitors with sensitive stomachs are especially advised to stick to bottled water.

    Practical Water Tips

    • • Buy bottled water from supermarkets (much cheaper than convenience stores)
    • • Ask for 'água mineral' (mineral water) at restaurants—it's standard practice
    • • Hotels typically provide filtered water or a mini-bar with bottled options
    • • Ice at restaurants and bars is usually made from filtered water and is safe
    • • Bring a reusable bottle with a filter to reduce plastic waste

    Staying Hydrated

    Rio's heat and humidity mean you'll need to drink more water than usual. Aim for at least 2-3 liters per day, more if you're active or at the beach. Coconut water (água de coco) is sold everywhere on the beach and is a natural, delicious way to stay hydrated and replace electrolytes.

    Quick Tip

    A 1.5L bottle of water at a supermarket costs about R$3 ($0.60). On the beach, coconut water from a fresh coconut is about R$8–10 ($1.50–2).

    Frequently asked questions

    Can you drink tap water in Rio de Janeiro?

    Tap water in Rio is treated to local standards but we don't recommend drinking it straight. Most Cariocas drink filtered water at home and buy água mineral (bottled mineral water) when out. Visitors with sensitive stomachs should stick to filtered or bottled water to be safe.

    Is it safe to brush your teeth with tap water in Rio?

    Yes — brushing your teeth and showering with Rio's tap water is fine for the vast majority of visitors. The caution is about drinking larger amounts. If you have a very sensitive stomach, use bottled water for brushing too, but most travellers never have a problem.

    Is ice safe in Rio restaurants and bars?

    Generally yes. Established restaurants, bars and hotels use filtered water and commercially produced ice, which is safe. Use normal judgement at very informal street stalls, but you don't need to refuse ice in your caipirinha at a proper bar — it's not a common source of trouble.

    Is bottled water expensive in Rio?

    No. A 1.5-litre bottle from a supermarket is around R$3–5; convenience stores and beach vendors charge more. Buy a few large bottles from a market for your room and carry a refillable bottle for the day rather than paying beach prices every time.

    Is coconut water (água de coco) safe to drink?

    Yes, and it's one of Rio's great pleasures. Fresh green coconuts sold on the beach and streets (R$8–12 in 2026) are naturally sealed, hydrating and full of electrolytes — ideal in the heat. Drink it straight from the coconut with a straw.

    Can babies and young children drink the tap water?

    Use filtered or bottled water for babies and young children, including for making formula, and to be extra cautious for brushing their teeth. Their stomachs are more sensitive to unfamiliar water, and bottled water is cheap and available everywhere, so it's an easy precaution.

    Are salads and raw vegetables safe to eat in Rio?

    At established restaurants, yes — salads at por quilo buffets and sit-down places are washed in treated water and eaten routinely. Be more cautious with raw produce from very informal street stalls. Peelable fruit is always a safe bet if you're worried.

    What should I do if I get an upset stomach in Rio?

    Rest, drink plenty of bottled water and rehydration salts (soro caseiro or sachets from any farmácia), and eat plain food. Pharmacies are excellent, well-stocked and everywhere in Rio. See a doctor if symptoms are severe, bloody or last more than a couple of days.

    Do hotels in Rio provide drinking water?

    Most hotels provide filtered water, a kettle or a minibar with bottled water, and many have filtered-water dispensers on each floor. Hostels usually have a filter in the kitchen. Check on arrival; if not, a supermarket run for a few large bottles solves it cheaply.
