Can You Drink Tap Water in Bangladesh?

One of the first questions we and most travelers to Bangladesh want to know is whether the tap water is safe to drink. It’s a fair question and seriously important. The only two times I’ve been sick when traveling were because of drinking bad water, when I drank water that someone told me was safe (filtered, boiled, etc.), and I didn’t deal with it or check it myself.  I was ill for weeks. It can have a massive impact on your trip and health.  So here’s my guide and answer to the question:  Can you drink tap water in Bangladesh?

The short version is simple, and the answer is no.  You should NOT drink the tap water in Bangladesh, but there are a few really important details. In this guide, I’ll walk you through whether you can drink tap water in Bangladesh, what’s actually safe, and how to avoid getting sick while you’re traveling in Bangladesh.

Can You Drink Tap Water in Bangladesh?

A tiny percentage of households in Bangladesh have access to a piped water supply, but according to WaterAid, 86% of the poorest households’ water supplies are contaminated with E.coli.  Of course, that isn’t your hotel in Dhaka, but even now, in 2026, when it’s said that 59% of Bangladesh’s population has access to safe drinking water, it does NOT necessarily mean the water comes from the tap.

Tap water is widely available across Bangladesh, but that doesn’t mean it’s safe to drink.  There is NOWHERE in Bangladesh where the tap water is safe to drink.

It wasn’t until January 2026 that the Bangladeshi Government declared that access to safe and potable water was an inherent component of the Right to Life under Article 32 of the Constitution of Bangladesh. That’s nearly 25 years since Bangladesh became an independent country, but once you start to travel around the country, you can understand why it’s taken so long.  It’s one heck of a challenge.

But it’s also important to remember that access to safe and potable water isn’t the same as having potable water from a tap.

The Short Answer: No

No, you should not drink tap water in Bangladesh.

Why Tap Water Isn’t Safe to Drink in Bangladesh

There are a whole number of reasons as to why Bangladesh, the 7^th most climate-impact vulnerable country in the world, has unsafe tap water.  This low-lying country is subject to frequent cyclones and tidal surges that result in saltwater impacting fresh water supplies.  Cyclones hit Bangladesh almost every year, with a severe one hitting, on average, every three years.

Domestic wastewater discharge often makes its way into rivers and freshwater supplies.  Seepage from pit toilets is common.  Discharge of chemicals from manufacturing processes into rivers.  The list is long.  You only have to look at the Buriganga River in Dhaka, down at Sadarghat, as we did when we explored Dhaka, to understand part of the problem.

There’s also been an over extraction of groundwater throughout the country, which has led to a degradation of the water table, as much as 3 meters a year in Dhaka, for instance.

And then there are the problems with what’s in the water in Bangladesh.

Arsenic in Drinking Water in Bangladesh

Now, to be fair, some arsenic is always found in water, but there are higher levels suggested by the WHO guidelines of arsenic found in some stored drinking water in Bangladesh.  A UNICEF report from 2018 detailed that arsenic concentrations above 10 parts per billion were found in stored drinking water in all 64 districts in Bangladesh.

Arsenic gets into the water naturally. It is found in alluvial sediments that have been deposited in the Bengal Delta over the past 11,700 years, and thus it contaminates the groundwater.

E.coli in Drinking Water in Bangladesh

UNICEF also indicates that e.coli contamination can be found in 50% of household supplies of drinking water.  Poor sanitation, flooding, leaking pipes, and poor storage hygiene contribute to this.

Bacteria, Parasites, and Other Contaminants in Drinking Water in Bangladesh

Tap water in Bangladesh can contain bacteria, parasites, and other contaminants that your body isn’t used to.  Even if locals drink it seemingly without issues, visitors often don’t have the same tolerance, which means it can quickly lead to stomach problems.

Tap Water Safety in Bangladesh

Even in the modern parts of Dhaka, like Gulshan, where water systems are more developed, it’s still not considered safe for visitors to drink directly from the tap.

Is Tap Water in Bangladesh Safe for Brushing Your Teeth?

I wouldn’t.  If water isn’t safe enough for drinking, then it’s not safe enough for brushing your teeth.  Use bottled or filtered water to brush your teeth.

Is Tap Water in Bangladesh Safe for Showering?

Yes, showering is fine. Just avoid swallowing water. If you’re a contact lens wearer, like me, then follow all the usual instructions about not wearing your lenses while showering, and ensuring that your hands are fully clean and dry before inserting your contact lenses.

Is Tap Water in Bangladesh Safe for Washing Your Face?

Yes, washing your face with tap water is generally fine, but again, avoid getting it in your mouth.

Is Tap Water in Bangladesh Safe for Washing Fruits & Vegetables?

No. Tap water is not ideal for washing anything you plan to eat raw. Use filtered or bottled water.

Is Tap Water in Bangladesh Safe for Hot Drinks?

Boiling water removes some of the danger, but not all.  We always used filtered or bottled water for hot drinks.

How to Get Safe Water to Drink in Bangladesh

There are a few safe and easy options for drinking water.  A huge number of people visit and live in Bangladesh and safely drink water every day.  Here are your options for drinking safe water in Bangladesh.

Use Bottled Water in Bangladesh

Bottled water is the most common and easiest option. It’s widely available and cheap.  It’s worth checking that the seal is intact when you buy it, as refilled bottles can occasionally be an issue, although we have NOT seen this at all.  The challenge is plastic waste.  And as you travel around Bangladesh, you’ll see that trash and waste are a massive problem.

Use Filtered Water in Bangladesh

Filtered water is often available in hotels, cafés, and some guesthouses. This can be a good option, especially if you want to reduce plastic use.  If you want to be certain that your water is filtered, then bringing a filter water bottle from Grayl or Lifestraw is the best option, and you’re truly in control of your own water supply.

When drinking water from unsafe sources, we use both a steripen and a filter water bottle.  And that’s because after getting sick in Nepal from trusting someone else to filter my water, I don’t ever want to go through those 8 weeks again.  The same happened in South America. It might be an extremely effective weight loss problem, but it is deeply unpleasant.

FAQs on Drinking Tap Water in Bangladesh

There are a few common questions that come up about safe drinking water in Bangladesh.

Should You Avoid Ice in Bangladesh?

In most cases, yes, unless you’re in a higher-end restaurant or hotel where you’re confident the ice is made from filtered water.  In the heat of South Asia, however, it’s also best to avoid drinking iced drinks.  You will rehydrate and cool down much more quickly if you drink room-temperature water.  Just ask for “normal”.

Should you drink Fruit Juices at a Market in Bangladesh?

While you’re exploring Bangladesh, you’ll visit more than one market. I recommend the areas of Old Dhaka that you can visit as part of this tour. And you’ll see drinks stalls, where there’s sugar cane juice, freshly squeezed lemon juice, and the like.  If you’re with a guide, then take their advice, but I wouldn’t drink juice from here.  Glasses and cups are often reused, and the hygiene is not what your constitution is used to.

Can You Drink Tea & Coffee in Bangladesh?

Yes. Hot drinks like tea and coffee are safe, as the water has been boiled.

What about Water in Hotels in Bangladesh?

All hotels provide bottled or filtered water for guests. It’s always best to use this rather than drinking from the tap.  If you run out (we did every day), then just ask for more, or buy from a store.  You’ll find bottled water available everywhere.

Do Filter Water Bottles Make Tap Water Safe in Bangladesh?

Yes, a good quality filter bottle can make tap water safe to drink. It’s a useful option if you want to avoid buying bottled water.  You should make sure that you have a good functioning filter and that it’s a recognized brand.  The best filter water bottles to use in Bangladesh are Lifestraw or Grayl.

Do Steripens Make Tap Water Safe in Bangladesh?

Yes, Steripens can be effective in making water safe in Bangladesh.  Steripens ultraviolet (UV-C) light to destroy over 99.9% of bacteria, viruses, and protozoa.  They work by disrupting the DNA/RNA of microorganisms, preventing them from reproducing or causing illness.

We don’t use them independently; we use a Steripen in conjunction with a filter water bottle.

Practical Tips for Drinking Water Safely in Bangladesh

Stick to bottled or filtered water, and keep a bottle with you at all times.  Check seals on bottled water, avoid ice, and be cautious with anything that might have been washed in tap water.  If you want to reduce plastic use, consider bringing a filter bottle.

Final Words on Drinking Tap Water in Bangladesh

Tap water in Bangladesh isn’t something to consider.  It’s best to stick to bottled or filtered water, take a few simple precautions, and you won’t have any issues staying healthy during your trip.  Filter water bottles and Steripens go with us on every trip and provide a level of security, but sometimes bottled water is the best way to go.
