Can You Drink Bathroom Tap Water in the UK?

by Dr. Jonathan Doyle - Updated November 13, 2025
As far as water intake is concerned, most of us do not appreciate this basic facility in our day-to-day lives. Even in countries like the UK, for instance, it is common to find that water from the kitchen tap is safe for drinking, but what is more concerning is whether water from other taps, like those in bathrooms, is safe for drinking because many of us are curious to know whether water from different taps in our homes is safe for drinking, which is what this article tries to clarify.

Bathroom Tap Water in the UK - Is it Drinking Quality?

In the UK, tap water is controlled by a body known as the Drinking Water Inspectorate (DWI) . Tap water is safe for drinking in most cases, but things get slightly complicated if it is in a bathroom.

Plumbing System Design

Taps in bathroom plumbing generally function as part of the same plumbing system as kitchen taps. Though, in case of problems in plumbing or perhaps in cases wherein bathroom water is stored in a different water tank, it may at times create a hazard.

Temperature of Water

Most bathrooms provide water from taps that is even colder than that of water in the kitchen, but water which has been allowed to stand in large quantities, perhaps in a water tank, might include bacteria which could influence whether this water is safe to drink.

Pipe Condition

Old pipes may be corroded, which results in water contamination. Even in cases where water is drawn from any tap, whether in the kitchen or bath, it is possible that it is not as pure as it is supposed to be.

Why May Bathroom Tap Water Be Less Safe?

Even if water from most taps in the United Kingdom is safe to drink, it is possible that water from bathroom taps may be less safe for several reasons:

Stagnation

The water in bathroom pipes may have a longer chance of being stagnant as compared to water in kitchen pipes; this increases the risk of water contamination . Organisms tend to grow in stagnant water, as in cases of less usage in water pipes.

Non-Potable Tank Water

Some households' bathroom faucets may be connected to a cold water storage in the attic, which is also not always maintained to standard standards by whoever is responsible for doing so, resulting in contaminants such as dirt, bacteria, and more, making this water unfit to drink.

Old Pipes

An old plumbing system in a house could result in water containing lead, copper, or other harmful contaminants leaching from old pipes, which is quite hazardous for drinking water.

What About Water from the Bathroom Sink?

In the UK, water from bathroom sinks is safe for drinking, as long as it is directly from the mains water supply in most homes. However, as previously stated, this risk of contamination is raised where the water supply is from a storage tank, as well as in old water pipes.

That is why it is recommended to drink water from a kitchen tap, where water is generally fresh, as it is less likely to have been stored in old pipes for quite a time.

Signs That Your Bathroom Tap Water May Not Be Safe to Drink

Unpleasant Smell/Taste

If the water is emitting a strange smell, it is an indication that it is contaminated. Sometimes, bathroom water may have an unpleasant metallic taste because it is stale in the pipes, perhaps from an uncleaned water reservoir.

Cloudy/Discoloured Water

Observation of cloudy or discoloured water in tap water may relate to air bubbles, minerals, or impurities in water. This could be more noticeable in bathroom water taps in case of stagnant water in pipes.

Low Water Pressure

Low water pressure could also mean that there is a water flow issue in the plumbing system, which could endanger water safety.

How Can You Ensure Your Bathroom Tap Water Is Safe?

Concerned about drinking bathroom tap water in the UK, here are several things that you, as a consumer, should do to make sure that drinking water is safe for consumption:

1. Frequently Clean Your Plumbing Lines

A house check by a professional for plumbing is always necessary, more so in an old house. Also, if in your house, water passes from a water storage tank, regular cleaning of this water storage tank is vital to avoid contamination from bacteria present in the water.

2. Employ Water Filtration Systems

One of the most effective ways to provide safe drinking water from any water tap in the house, including those in bathrooms, is by installing a water filtration system in the house. Though water from kitchen water taps in most houses is safe, having a Waterdrop water filtration system installed in the house is also beneficial for increasing water quality by filtering unwanted substances such as chlorine, lead, and bacteria present in water.

3. Choose a Water Filter for Bathroom Taps

Concerned about bathroom tap water quality? A water filtration system for bathroom faucets would be a good addition to have in this regard. You could also look into a water filter that directly attaches to your tap for cleaner water.

Final Note

In short, tap water from bathrooms in the UK is safe for drinking, but certain conditions such as water stagnation, poor plumbing, as well as potential contaminants, might render this water less than suitable for drinking.
For increased assurance that only safe, clean drinking water is being consumed, it is always worthwhile to have plumbing systems tested from time to time, in addition to having a Waterdrop water filtration system at home.
Drinking water is a fundamental requirement for enjoying good health, and ensuring that water from the tap is clean is just as imperative. Whether water is from the kitchen sink or bathroom sink, it is always important to be aware of water quality to ensure that it is safe for consumption by members of your household.
