Bangkok, the vibrant capital city of Thailand, is a bustling metropolis known for its ornate shrines, street markets, and tantalizing cuisine.

Is it safe to drink the tap water in Bangkok?

The tap water in Bangkok is not considered safe for drinking without prior treatment.

The water quality and infrastructure for water treatment and distribution can vary in different parts of the city.

With that saying, tap water in Bangkok is considered “safe,” but the locals in Bangkok don’t drink tap water as it is not recommended.

Many locals and visitors drink bottled water or use filtered water for drinking and cooking.

So as tourists, I recommend you drink bottled water only instead of drinking tap water to be on the safe side.

Where can I find safe drinking water in Bangkok?

It is easy to find bottled drinking water in all parts of Bangkok.

Most convenience stores, supermarkets, and street vendors sell packaged distilled or filtered water.

I like buying my water bottles at seven eleven, Bangkok’s most reliable bottled water source.

If you are staying at a hotel or hostel, they usually offer free drinking water from filtration systems.

Check with the staff to make sure it is safe and filtered correctly.

Prices vary depending on the size and brand of the bottle, but they are generally very affordable.

Additionally, many restaurants and cafes offer free boiled or filtered water.

If you are unsure if the water is safe to drink, it is best to ask before ordering your meal.

This will ensure you drink clean and safe water throughout your stay in Bangkok.

Can you use tap water in Bangkok?

Although it is not recommended to drink tap water in Bangkok, it can still be used for other purposes, such as washing vegetables and cooking.

It is important to note that boiling tap water first is essential for food safety if you plan on using it for any purpose.

This will help ensure that all bacteria and contaminants are killed before consumption.

It is also important to note that most hotels and guesthouses in Bangkok provide filtered water for guests, so be sure to ask about this when booking your accommodations.

This way, you can use the provided water while staying there without worrying about boiling tap water.

Is the water clean in Bangkok?

Yes, the water in Bangkok is generally clean.

Most of the water from the taps is treated and filtered to remove contaminants such as bacteria, metals, and other pollutants.

However, drinking tap water without prior treatment is still unsafe due to potential contamination from old pipes and other sources.

Therefore, it is best to stick with bottled or filtered water when in Bangkok.

Is it OK to brush your teeth with tap water in Bangkok?

Yes, brushing your teeth with tap water in Bangkok is generally safe.

However, if you have a sensitive stomach or weakened immune system, opting for bottled or filtered water instead of using tap water directly is best.

Overall, brushing your teeth with tap water in Bangkok should not pose serious health risks if you practice good hygiene and take the necessary precautions.


Overall, tap water in Bangkok is considered “safe” but not recommended for drinking.

Tap water should not be consumed without prior treatment as it can contain bacteria and other contaminants that can cause illness.

For this reason, drinking bottled or filtered water is recommended.

It is easy to find bottled or filtered water in most convenience stores, supermarkets, and restaurants throughout the city.

If you have any questions about the safety of drinking tap water in Bangkok, it is best to ask a local for advice.
