Every hotel in China provides bottled water in the room. Restaurants serve hot tea rather than tap water. Convenience stores on every block sell 550ml bottles for ¥1–¥3. The message is clear, even without reading it anywhere: locals in China do not drink from the tap, and you should not either.
Here is why and the practical ways to stay hydrated throughout a China trip without going broke on bottled water.
Key Takeaways
- Do not drink tap water in China: not even in five-star hotels.
- Boiling helps but does not fully fix it: heavy metals are not removed by boiling.
- Bottled water is very cheap: ¥1–¥3 for 550ml at any convenience store.
- Free water dispensers exist at train stations, airports, and public buildings: bring a refillable bottle.
- Hot water (热水) from your hotel kettle is fine for tea and instant noodles.
- Brushing teeth with tap water is generally fine: the risk is from ingesting, not brief contact.
Why Is Tap Water Unsafe in China?
China’s water treatment plants are technically capable – the treated water leaving a plant in a major city typically meets WHO standards for microbiological contaminants. The problem is what happens between the plant and your tap.
Distribution pipes in older Chinese buildings are often made of galvanised iron or older materials that corrode over time. As water travels through these pipes, it picks up lead, rust, sediment, and other contaminants. A 2019 study published in Water Research found elevated lead levels in tap water in Chinese cities particularly associated with older residential buildings. The WHO guideline for lead in drinking water is 10 micrograms per litre – some samples from older Chinese buildings exceeded this.

What Is Safe to Do With Tap Water
| Activity | Safe With Tap Water? | Notes |
| Drinking | No | Use bottled or filtered water |
| Brushing teeth | Generally yes | Brief contact; not swallowed in quantity |
| Showering / bathing | Yes | No absorption risk from skin contact |
| Making tea or coffee (boiled) | Acceptable | Boiling kills bacteria; minerals remain |
| Cooking pasta/rice (boiled) | Acceptable | Boiling and high heat reduce risk |
| Ice in drinks | Caution | Ice at restaurants uses tap water — specify no ice if concerned |
| Washing fruit/vegetables | Rinse with bottled if eating raw | Residual water on raw produce is ingested |
Cheapest Ways to Stay Hydrated
Option 1: Bottled Water (Most Common)
A 550ml bottle of Nongfu Spring or C’estbon costs ¥1–¥3 at any convenience store (7-Eleven, FamilyMart, Lawson, local shops). A 1.5L bottle costs ¥3–¥5. Both brands are safe and filtered to drinking quality. For a week-long trip staying active, budget ¥10–¥20 per day for water — a negligible cost.
Option 2: Free Dispenser Refills
Chinese train stations, airports, hospitals, universities, and many shopping malls have free water dispensers (饮水机) in common areas. These dispense filtered hot and cold water. Bring a refillable 500ml–1L bottle and fill up whenever you pass one. You will pass one in every high-speed rail station — filling up before boarding a long train journey means you do not need to buy from the onboard trolley.
Option 3: Large Purified Water Jugs
For longer stays in one place (a week+ in one city), 5L bottles cost ¥5–¥8 and 18.9L dispenser jugs cost ¥10–¥20 at supermarkets like RT-Mart, Carrefour, or the app-based delivery platforms (Meituan, JD). Far cheaper per litre than individual bottles.

Option 4: Portable Filter
A LifeStraw, Sawyer Squeeze, or similar portable water filter removes bacteria, protozoa, and microplastics from tap water. Most do not remove heavy metals or dissolved chemicals. For the specific heavy metal concern in China, a filter with an activated carbon stage (like certain Sawyer or Katadyn models) provides better coverage. Useful for adventure travelers or long trips where buying bottled constantly is inconvenient.
Hot Water Culture in China
China has a strong cultural preference for hot or warm water over cold. The belief that cold water is bad for health is deeply embedded — even in summer, hot water (热水, rèshuǐ) is offered at restaurants as the default. This means:
- Your hotel room always has a kettle. Use it for tea or hot drinks.
- Restaurants will give you free hot water if you ask. Say: wǒ yào rèshuǐ (我要热水).
- Ice in drinks is less common than in Western countries — often you have to specifically request it.
- On Chinese trains, every carriage has a hot water dispenser (开水, boiling water) — for instant noodles and tea.
