New to Barcelona? Make the tap water taste good
Say goodbye to tap water worries & bad taste.
Is Barcelona tap water safe to drink?
Yes. Drinking water in Spain must meet Royal Decree 3/2023, and the latest SINAC bulletin for every Barcelona supply zone says the water is fit for consumption. Read more in can you drink tap water in Barcelona.
What newcomers notice is the taste. Mains water is disinfected so it stays safe all the way to your tap, and some people taste that chlorine. Most of the city also has hard water: Zone D, which supplies 72% of Barcelona, measured 32.9 °f in its latest sample (hardness by zone). That is why so many people here end up buying bottled water.
Bottled water delivery or a filter at the tap?
Water delivery means 20-litre bottles to carry, store and swap, a dispenser in the kitchen, and running out at the wrong moment. A filter at the tap gives you unlimited water with nothing to carry. We compare both honestly, including when delivery is the better choice, in water delivery vs. a tap filter.

Renting? We leave the kitchen as we found it
Most expats rent, so the system is built for that. The standard tap needs a 1.3 cm hole in the worktop; when you move out, we cover it neatly. If you would rather not drill at all, we replace your existing tap with a 3-way tap (€79.90, yours to keep) that gives normal and filtered water from one spout. Check your rental contract if you are unsure what changes it allows.
If you move to a new flat within our area, we uninstall and reinstall the system for free.
Signing up, in English
Message us on WhatsApp in English with your postcode and a photo of the cupboard under your sink. We confirm it fits, book a visit (usually within 1–5 days) and install it in about two hours. We measure your water before and after and show you the numbers.
€24.90/month or €249/year in Barcelona city; €27.90/month or €279/year in Badalona, L'Hospitalet, Sant Cugat and Esplugues. Installation, filter changes and maintenance included. No deposit, no upfront cost, no minimum term: two months' written notice to cancel.

Water filters for expats: common questions
Is tap water in Barcelona safe to drink?
Yes. It meets Spain's drinking water regulations (Royal Decree 3/2023), and SINAC lists every Barcelona supply zone as fit for consumption. Many people filter it for taste, not safety.
Why does Barcelona water taste of chlorine?
Mains water is disinfected so it arrives at your tap in good condition. Some people taste that disinfection, especially if they are used to bottled water. Our system reduces chlorine by 99.5% (SGS test, new membrane).
Do I need my landlord's permission?
We leave the kitchen as we found it: a neat cover over the tap hole when you leave, or a 3-way tap with no drilling at all. Check your rental contract if you are unsure what it allows.
Do you speak English?
Yes. You can sign up, ask questions and get support in English on WhatsApp.
What happens if I move?
If you move within our area, we reinstall the system at your new flat for free. If you leave Barcelona, cancel with two months' written notice.
Which areas do you cover?
Barcelona city, Badalona, L'Hospitalet de Llobregat, Sant Cugat del Vallès and Esplugues de Llobregat.
