After a long travel day, that first glass from the hotel tap can feel like a small gamble.

Can You Drink Tap Water In Prague? Safety Basics For Visitors
For the vast majority of travelers, Prague tap water from the public supply is fine to drink straight from the tap. Large treatment plants such as Želivka and Káraný feed the city network and are checked constantly for microbes, metals, and other unwanted substances.
So if you are still wondering can you drink tap water in prague?, the answer is yes in regular hotels, apartments, offices, malls, and most food spots on the city network. The main exceptions tend to be private wells on the edge of the city or older buildings with outdated internal pipes.
| Place Or Situation | Is Tap Water Safe? | Notes For Travelers |
|---|---|---|
| Standard hotels in central Prague | Yes | On the city network, checked under Czech and EU rules. |
| Modern apartments and Airbnb stays | Yes, in almost all cases | Ask your host only in older or freshly rebuilt houses. |
| Traditional restaurants and bistros | Yes | Staff usually drink tap water; you can request a carafe. |
| Cafes and coffee shops | Yes | Coffee and tea use tap water that has already been boiled. |
| Public drinking fountains | Usually yes | Look for “pitná voda” signs before you fill your bottle. |
| Old homes with original metal pipes | Mixed | Run the tap briefly and ask a local if you have doubts. |
| Private wells outside the main network | Not always | Water may not be tested often; locals often filter or buy water. |
| Day trips to remote villages | Check locally | Carry a filter or bottled water until you learn the source. |
Locals notice that Prague tap water tastes a bit different from one district to another. That comes from the mix of softer surface water and harder groundwater, yet safety standards stay the same across the network.
How Prague’s Tap Water System Works
Understanding how the city treats and checks its water can make that first sip from the bathroom sink feel more relaxed. Prague draws its drinking water from surface reservoirs and protected groundwater areas, then runs it through treatment before it reaches your tap.
Where The City Water Comes From
The largest source is the Želivka water treatment plant south of the city. A second share comes from Káraný, a groundwater source northeast of town with slightly harder water, and a third plant at Podolí covers peak demand and backup needs during repairs or droughts.
Treatment And Disinfection
Before the water reaches taps, it passes through filtration, including layers of sand and sometimes activated carbon that catch particles and trace chemicals. Disinfection, mainly through controlled dosing of chlorine, keeps microbes under control as the water moves through long pipes under the city streets.
Monitoring And Legal Standards
Drinking water in large Czech systems is sampled throughout the day at plants and across the network, with results stored in national databases overseen by health authorities. In Prague this work is described by the Prague water company and follows Czech law based on European Union standards for drinking water, which set limits on microbes, pesticides, heavy metals, and many other substances.
Drinking Tap Water In Prague Safely And Comfortably
Once you know the system behind the tap, daily choices become simple. Here is how to handle the most common travel situations involving Prague tap water, from brushing your teeth to filling bottles for long walks along the river.
Hotels, Apartments, And Other Stays
In standard hotels and modern apartment blocks on the city network, you can drink from the bathroom tap, fill the kettle, and brush your teeth with no special steps. Many hotel staff members do exactly the same at work and at home.
If your room sits in an old building, you may see pipes that were installed long ago. In that case, let the cold water run for a short time in the morning before filling your glass, especially if the tap has not been used overnight. If the water looks cloudy for more than a few seconds, or you notice odd smells or colors, ask reception or your host for advice.
Restaurants, Cafes, And Bars
When you sit down for a meal, you can ask for tap water instead of bottled water. The phrase to use is “kohoutková voda” or “voda z kohoutku,” which both mean tap water. Some places pour a carafe for free or for a small service charge, while others prefer to sell bottled water; this difference comes from house rules instead of safety concerns.
Hot drinks and soups rely on water that has been boiled, which adds another layer of safety. Ice cubes in city bars and cafes usually come from the same treated supply; if you often get stomach upsets, skip ice on your first day and see how your body responds.
Public Fountains And Bottle Refill Points
Prague has an increasing number of public fountains and bottle refill taps, especially in parks and around busy tram stops. Many connect directly to the city network and are marked with signs that say “pitná voda.” When you see that phrase, the water is meant for drinking.
Some decorative fountains use recirculated water that is not meant for drinking, so always check for a sign. If you see “nepitná voda,” treat it as non drinking water and keep your bottle closed.
When Bottled Water Or Filters Make Sense
Even in a city with safe tap water, there are a few cases where a filter or bottled water may feel more comfortable. This does not mean Prague tap water fails safety tests; it is more about taste, personal health, and short stays in places with separate local systems.
Sensitive Stomachs And Health Conditions
Travel itself can upset digestion, and any sudden change in minerals or microbes can add to that. The CDC food and water advice for travelers notes that minor stomach trouble can appear even where basic water safety is strong.
Travelers with weakened immune systems, those receiving cancer treatment, or anyone on strict medical guidance may prefer extra layers of care. A simple bottle with a built in filter or boiled water cooled in a clean container can make daily choices feel easier during the trip.
Babies And Young Children
Parents often worry more about water for formula and toddlers than for themselves. Prague tap water from the city supply is cleaned and checked to a level that covers children as well as adults, yet many parents still prefer to boil water for baby bottles or use bottled low mineral water on short trips.
If you prepare formula with tap water, let the cold tap run for a short time, then boil the water and allow it to cool in a clean kettle or pan. Avoid filling bottles from hot tap water, since water that sits in a heater can pick up more minerals from the tank.
Day Trips Outside Prague
Once you leave the capital for smaller towns, mountain areas, or remote cottages, water sources can change. Large Czech towns usually have safe tap water similar to Prague, while tiny villages sometimes rely on small local systems or private wells.
On hiking trips, carry a refillable bottle from Prague plus a small travel filter or disinfection tablets for streams and rural taps. Local hosts are usually happy to tell you whether their water comes from the public network or from a private source that needs boiling or treatment before you drink it.
| Traveler Situation | Tap Water Plan | Extra Tips |
|---|---|---|
| Healthy adult in city center | Drink straight from the tap | Carry a refillable bottle and top up during the day. |
| Short city break with mild stomach worries | Start with small glasses | Mix tap and bottled water on day one. |
| Traveler with long term illness | Tap water plus simple filter | Use a personal filter bottle or boil drinking water. |
| Family with baby on formula | Boiled tap or bottled water | Use fresh cold tap water, boil, then cool before mixing. |
| Weekend at a rural cottage | Check the source first | Ask if the house uses the public network or a private well. |
| Hiking in Czech national parks | Do not drink straight from streams | Filter or boil river and spring water before drinking. |
| Long stay digital nomad | Use tap water daily | Add a small countertop filter if you dislike hardness. |
Final Tips For Drinking Tap Water In Prague
By now, the question can you drink tap water in prague? should feel settled. Under normal conditions, city tap water is safe, checked often, and used every day by residents, so you can travel lighter and skip most bottled water.
To recap the main habits: stick to cold tap water from the public network, let the tap run briefly in old buildings, and watch for “pitná voda” or “nepitná voda” signs at fountains. In bars and restaurants, do not hesitate to ask for tap water along with your meal or coffee.
If you live with a complex medical condition, plan ahead with your doctor and pack a filter bottle or simple treatment method. For everyone else, Prague tap water offers a safe, low cost way to fill your glass while you wander the Old Town, ride the trams, and enjoy long days on foot.
