Can You Drink Shower Water in Australia?
Why the Cold Kitchen Tap Wins Every Time
You can, but it isn't the water you want in your glass. A shower blends in water from your hot water system, and Australian health departments are clear: only drink from the cold tap. The good news is the fix is simple. Drink from the cold kitchen tap, filter it with a benchtop system, and give your shower its own filter for your skin and hair.

Don't use the shower as a drinking tap. Australian mains water is treated to meet the Australian Drinking Water Guidelines, but the shower mixes in hot water, and NSW Health, the Tasmanian Department of Health and NT Health all say to use only cold tap water for drinking and cooking. Water also sits in the shower arm, hose and head between showers.
For drinking, use the cold kitchen tap, ideally through the HolyH₂O Trinity benchtop filter. For showering, add a Shower Mate to cut the chlorine on your skin and hair. Comparing every shower option? See our best shower filter Australia guide.
Where this comes from: the hot tap and flushing advice is from NSW Health, the Tasmanian Department of Health and NT Health drinking water pages, checked October 2026. Product figures are from HolyH₂O product pages and third-party testing of the Trinity by AS Enviro, an ISO/IEC 17025:2017 accredited laboratory. Results vary with your water.
Shower vs Kitchen Tap: Where the Water Comes From
In most Australian homes, every cold tap is fed by the same treated mains water. What changes at the shower is the hot water blended in and the fittings it travels through. That's why the kitchen cold tap is the drinking tap, and the shower is for washing.
| Tap | Where the water comes from | Drink from it? | Best HolyH₂O match |
|---|---|---|---|
| Kitchen cold tap | Treated mains water, straight from the pipe | ✓ Yes, the one to use | Trinity or Tap Mate |
| Bathroom basin cold tap | Usually the same mains supply | ⚠ Cold only, flush first | Keep drinking at the kitchen |
| Shower | Mains cold blended with water from the hot water system | ✗ Not a drinking tap | Shower Mate or Shower Max |
| Any hot tap | The hot water system | ✗ Never, say health departments | Use cold for the kettle |
| Rainwater tank tap | Roof runoff, not treated mains water | ⚠ Depends on your tank | See our tank water guide |

Why the Hot Water Is the Real Problem
Three state health departments say the same thing: use the cold tap for drinking and cooking. Hot water can carry more dissolved minerals and metals, because heating water can draw more metals out of pipes and fittings. A warm shower always includes water from the hot water system, so it falls on the wrong side of that rule.
"Use water from the cold water tap for drinking and cooking." Hot water can contain more dissolved minerals and metals.
"Never drink from a hot water tap." Only use water straight from the cold tap inside the home for drinking or cooking.
Use cold tap water for drinking and cooking, never hot. Flush taps daily with about 10 seconds of cold water first thing in the morning.
A shower blends hot and cold, so its water is partly hot-system water. Treat it as washing water, not drinking water.
The simple rule: if a tap can run hot, it isn't your drinking tap. Older pipes and brass fittings are part of the reason, and our guide to lead in Australian tap water and pipes explains how plumbing affects what reaches your glass.
Four More Reasons the Shower Isn't a Drinking Tap
Even setting the hot water aside, the shower is built for washing, not drinking. Water sits in its fittings, it can be fed differently from the kitchen, and any filter on it is designed for skin and hair.
Between showers, water rests in the shower arm, hose and head. Health departments tell us to flush drinking taps after water has been sitting, which is a good hint about the first splash from a shower.
Some homes plumb a rainwater tank into parts of the house. Know what feeds your bathroom before you treat any tap there as a drinking tap.
Mains water carries chlorine or chloramine to keep it safe through the pipes. Fine to drink, but it's the taste and smell you notice most in a hot, steamy shower. See what a shower filter removes.
KDF and catalytic carbon are chosen to work in hot, fast-flowing water for your skin and hair. They don't turn the shower into a drinking tap.

See the setup ↓What About the Bathroom Basin Tap?
The cold basin tap in most homes is fed by the same mains water as the kitchen, so the rules are the same: cold only, and flush it for about 10 seconds first thing in the morning. After a holiday or a few days away, run it for about 2 minutes. Health departments suggest using the flushed water for plants or washing up.
That said, the kitchen is still the easier place to keep good drinking water, because that's where a filter, the kettle and your glasses already live. Renting? Our renter's guide to tap water filters covers no-drill options for both rooms.
- Drinking from the shower or filling a bottle there.
- Filling the kettle or cooking pot from the hot tap to save time.
- Drinking the first water out of a tap after a weekend away without flushing it.
- Assuming a shower filter makes shower water drinking water.
- Drinking from a bathroom tap without knowing if a rainwater tank feeds it.
The Better Setup: One Filter for Each Job
Drinking water and shower water need different filters, because they do different jobs. A benchtop filter handles the cold water you drink and cook with; a shower filter handles hot, fast-flowing water for your skin and hair. Here's how the HolyH₂O range splits the work.

Shower filters reduce chlorine, chloramine and sediment; they don't soften hard water or reduce fluoride. Fluoride reduction is a job for the Trinity's activated alumina stage. Installing a shower filter for the first time? Our shower filter install guide takes about two minutes to read.
Drinking Shower Water FAQs
Can you drink shower water in Australia?
It isn't a good idea to use the shower as a drinking tap. Australian mains water is treated to meet the Australian Drinking Water Guidelines, but a shower mixes in water from your hot water system, and state health departments advise using only the cold tap for drinking and cooking. For a glass of water, use the cold kitchen tap, ideally through a benchtop filter like the HolyH₂O Trinity.
Is shower water the same as kitchen tap water?
In most Australian homes the cold water in the shower comes from the same mains supply as the kitchen. The difference is that shower water is usually blended with hot water from the hot water system, and it sits in the shower arm, hose and head between uses.
Why shouldn't you drink water from the hot tap?
NSW Health, the Tasmanian Department of Health and NT Health all advise against it. Hot water can contain more dissolved minerals and metals, because heating water can draw more metals out of pipes and fittings. Use the cold tap for drinking, cooking and filling the kettle.
Is bathroom basin tap water safe to drink?
The cold basin tap in most homes is fed by the same mains water as the kitchen, so the same rules apply: cold only, and run it for about 10 seconds first thing in the morning. If a rainwater tank feeds any part of your bathroom, check which taps it supplies before you drink from them.
Does a shower filter make shower water drinkable?
No. A shower filter like the HolyH₂O Shower Mate is built to reduce chlorine, chloramine, rust and sediment in hot, fast-flowing shower water for your skin and hair. It isn't a drinking water filter, and it doesn't change the hot water that comes through the shower. Drinking water belongs at the cold kitchen tap, where a benchtop filter like the Trinity does that job.
How long should I run the tap before drinking?
Health departments suggest running the cold tap for about 10 seconds first thing in the morning, and for about 2 minutes after the house has been empty for a few days, such as after a holiday. Use the flushed water for plants or washing up.
Can I fill the kettle from the hot tap to save time?
Health departments advise against it. Always fill the kettle and cooking pots from the cold tap, because hot water from the hot water system can carry more dissolved metals and minerals.
What's the best way to filter both drinking and shower water?
Use one filter for each job. The HolyH₂O Trinity benchtop filter looks after the water you drink and cook with, with third-party tested reductions of 99.5% fluoride, over 99.9% chlorine and 99.0% chloramine. The Shower Mate looks after the water on your skin and hair, reducing up to 99% of chlorine plus chloramine with KDF and catalytic carbon.
