Is Bathroom Water Safe to Drink?
by Dr. Jonathan Doyle - Updated January 15, 2025
When you’re thirsty, it’s easy to turn to the tap for a quick drink of water. But if you’re standing in the bathroom, you might hesitate for a moment. Is bathroom water safe to drink? This is a common question many Australians ask, and it’s important to get the facts straight before you sip. In this blog, we’ll explore whether bathroom water is safe to drink in Australia, the potential risks, and what you can do to ensure your drinking water is pure and safe.
The Safety of Drinking Bathroom Water in Australia
Water in Australia is generally treated and regulated to be safe for consumption. However, the safety of water can vary depending on its source, treatment, and how it’s stored. When it comes to bathroom water, there are a few key factors that could affect its quality.
Drinking Water Standards in Australia
Australia has stringent regulations in place to ensure the water supply is safe for all residents. According to the Australian Drinking Water Guidelines (ADWG), all public water supplies must meet specific standards to ensure that water is free of harmful contaminants. These guidelines focus on microbial, chemical, and radiological safety.
This means that water from the tap, whether in your kitchen, bathroom, or any other part of your home, is supposed to meet these standards if you are connected to a municipal water supply.
However, there are a few things to consider before drinking water from the bathroom tap.
Potential Contaminants in Bathroom Water
While tap water across Australia is treated for safety, the bathroom tap might be at a higher risk of certain contaminants. Here are a few reasons why you might want to think twice before drinking bathroom water:
Water Storage and Pipes
The water from your bathroom tap comes from the same supply as your kitchen tap, but there’s a key difference – the plumbing system. In many homes, water in the bathroom pipes has often been sitting unused for longer periods. This can result in stagnant water that may collect minerals or even bacteria over time.
In older homes, the pipes themselves may be made of materials like lead or galvanized steel, which can leach harmful substances into the water. This is particularly a concern in homes built before the 1970s, where plumbing systems may not meet current safety standards.
Mould and Mildew
Bathrooms are naturally damp environments, and this moisture can promote the growth of mould and mildew in places like taps, shower heads, and the surrounding areas. While these contaminants may not directly affect the water supply itself, they can contribute to unpleasant tastes or odors when you turn on the tap.
Temperature Fluctuations
The water temperature in the bathroom tends to fluctuate more than in the kitchen. If the water has been sitting in the pipes for a while, it may be more prone to bacterial growth, especially if the water is heated to a warm temperature.
Is Bathroom Water Safe to Drink in Australia?
In most cases, water from the bathroom tap in Australia is just as safe to drink as water from the kitchen tap. However, there are some instances where you might want to be more cautious:
For most Australians, however, there is minimal risk when it comes to drinking bathroom water, especially if the home is well-maintained and the plumbing system is up to standard.
What About Water from the Toilet Tank?
If you’re wondering whether water from the toilet tank is safe to drink, the answer is no. While the water in the toilet tank comes from the same water supply as your tap, it’s exposed to many potential contaminants. Toilet tanks can harbour bacteria, mould, and even chemicals from cleaning products. So, it’s always best to avoid drinking water from the toilet tank or bowl.
How to Ensure Safe Drinking Water at Home?
While bathroom water is generally safe to drink in Australia, there are ways to ensure that the water you consume is as pure as possible. Here are some tips:
Install a Water Filter
A good quality water filter can remove impurities, chlorine, and even bacteria from your drinking water. Installing a filter on your kitchen tap or throughout your home can provide you with an extra layer of protection and peace of mind.
Regularly Maintain Your Plumbing System
Keep your pipes and taps clean and free from mould or mildew. If you live in an older home, consider replacing any old plumbing systems, especially if the pipes are made of lead or other hazardous materials. Regularly flushing the taps can also help keep the water clean and fresh.
Check Your Water’s Taste and Smell
If you notice a strange taste or odour coming from your bathroom tap, it could be a sign of contamination. In that case, avoid drinking the water and contact your local water supplier for advice. You may need to flush your pipes or install a water filtration system.
Stay Updated on Local Water Quality Reports
Many local councils in Australia provide annual water quality reports, which include information on the safety of drinking water in your area. Check these reports to stay informed about any potential issues with your water supply.
Conclusion: Should You Drink Bathroom Water in Australia?
For the majority of Australians, drinking water from the bathroom tap is generally safe, as long as the water supply is treated and the plumbing system is in good condition. However, it’s important to be mindful of any potential risks, especially if you live in an older home with outdated plumbing or if you notice any unusual signs in your water, such as taste, colour, or smell.
If in doubt, consider installing a water filter or using a kitchen tap for drinking water. And remember, never drink water from the toilet tank, as it can contain harmful bacteria and chemicals.
By following the tips outlined in this guide, you can enjoy clean, safe drinking water from all taps in your home – whether they’re in the bathroom, kitchen, or elsewhere.
