Bottled vs Tap Water in China: What Is Actually Safe to Drink

China's tap water is treated at the plant but older pipe infrastructure can introduce contamination between the plant and your tap. The default for visitors is: boil or use bottled water.

Boiling is the Chinese cultural norm — every hotel room has a kettle, train stations have hot water dispensers, and thermos flasks are a daily institution. Boiling kills bacteria and viruses; it does not remove heavy metals, but short-visit exposure is not a meaningful concern.

Bottled water is cheap and ubiquitous: Nongfu Spring, C'estbon, and Wahaha are the major brands. A 550 ml bottle costs ¥1–3. The advice is consistent across Beijing, Shanghai, Guangzhou, Chengdu, and Xi'an — boil or bottle, especially in older buildings.

Restaurants use boiled or filtered water for cooking and for the free tea poured at tables. Ice is generally fine at decent restaurants. Rural areas and older buildings warrant more caution.

Practical approach: drink bottled water, use the hotel kettle, and do not overthink it. The cost is minimal and the risk eliminated.
