Can you brush your teeth with tap water in Bali? This is one of the most common questions travelers ask before visiting the island. While Bali is a world-famous destination known for its beauty, culture, and hospitality, water safety is something you should understand clearly to avoid unnecessary health issues during your stay.
Is Tap Water in Bali Safe?
In short, tap water in Bali is not considered safe for drinking. The water supply may go through basic treatment processes, but it is not purified to the same standards found in countries like Australia, the United States, or most of Europe. Contamination can occur during distribution through old pipes or storage tanks.
Even though locals may use tap water for daily activities, travelers—especially those not used to local bacteria—are more likely to experience stomach problems if they ingest it.
Can You Use Tap Water to Brush Your Teeth?
Yes, you can brush your teeth with tap water in Bali, but with some caution.
For most travelers, using a small amount of tap water while brushing is unlikely to cause serious illness, especially if you spit it out and rinse minimally. However, there is still a small risk of ingesting bacteria, which can lead to mild digestive issues such as “Bali Belly.”
Safer Approach
To reduce any risk, many visitors prefer to:
- Use bottled water for brushing teeth
- Rinse their mouth with bottled or filtered water
- Avoid swallowing any tap water
This is especially recommended for:
- People with sensitive stomachs
- Children
- Travelers staying for a short period
- Anyone wanting to avoid even minor health disruptions
What About Hotels and Villas?
Higher-end hotels, resorts, and private villas often have filtered water systems installed. In some cases, the tap water in these places is safer for brushing your teeth.
However, you should not assume all accommodations have drinkable tap water unless clearly stated. If in doubt, ask the staff or simply use bottled water to stay on the safe side.

- Consuming contaminated water
- Eating improperly washed fruits or vegetables

Even small exposure—like brushing your teeth with unsafe water—can contribute to the risk, although it is less likely than drinking it directly.
