Why your shower water may smell like chlorine
You are smelling the disinfectant your utility leaves in the supply on purpose. Whether it reaches you in the steam depends on which kind your city runs.
Free chlorine and chloramine behave differently
Water utilities maintain a disinfectant residual through the network. Australian supplies commonly use free chlorine or chloramine.
Leaves the water and gets into the air
Free chlorine is volatile. Warm water and fine spray can make its smell more noticeable in an enclosed shower.
That is why the smell may be easier to notice in the shower than at the kitchen tap.
Stays dissolved in the water
Chloramine combines chlorine with ammonia and remains more stable over long pipe runs.
It is less volatile, so smell alone is not a reliable way to identify it.

A pool-like smell can indicate free chlorine, but local utility information gives a more reliable answer.
The disinfectant type matters when choosing filtration. Carbon adsorbs free chlorine, while vitamin C reduces both free chlorine and chloramine through a chemical reaction.
See the chemistry page for the reaction, testing conditions and limits.
Check the disinfectant used in your area
The smell depends on the disinfectant used, its concentration and your local supply. Utility data gives a better answer than a national generalisation.
Melbourne
Why Melbourne is the strongest case
Free chlorine at a residual of about 0.76 mg/L. Free chlorine is the volatile one, so if any Australian city is going to give you a shower that smells like a pool, it is this one. If you are in Melbourne and you noticed a smell, you noticed something real.
Sydney
Sydney commonly uses chloramine, which is less volatile than free chlorine. A weak smell does not mean disinfectant is absent.
It also means the smell is a poor test for you. Sydney is a chemistry question rather than a nose question.
Brisbane and Ipswich
Seqwater adds chloramine before the water enters the South East Queensland grid, so it is still in the water when it reaches your shower.
What that means for a Brisbane shower
Chloramine does not leave the water in the steam the way free chlorine does, so a Brisbane shower can carry disinfectant you cannot smell. That makes chemistry the better test here, and vitamin C is the media that works on chloramine.
Adelaide
Why your neighbour may get a different answer
SA Water has disinfected South Australian water with chloramine since the 1980s, and names the supplies it chloraminates, from the Mid North and Yorke Peninsula to the southern Adelaide Hills. Its drinking water profile returns the disinfectant for your own postcode, which beats any city average.
Perth
Where the Goldfields fit
Water Corporation uses chloramination in the Goldfields rather than in metropolitan Perth, so a metro shower is on free chlorine and the smell is the volatile kind.
Canberra
Icon Water disinfects with chlorine and does not use chloramine at any point in treatment or distribution.
What that means in a Canberra shower
Icon Water says chlorine can be more noticeable when water is heated, which is exactly what a shower does.
Hobart
TasWater disinfects with chlorine and monitors the level across its network. It says the taste or smell can be more noticeable close to a dosing point or when flow is low.

Free chlorine is more volatile than chloramine
Free chlorine is more volatile than chloramine. Melbourne and metropolitan Perth run free chlorine, Sydney and Brisbane run chloramine, and in South Australia it depends on the supply.
Smell can be more noticeable where free chlorine is used, while chloramine may be harder to detect by smell. Check your local supply before choosing a filter.
If the smell is musty, earthy or metallic
These smells may have a different cause. Contact your water utility and check its current water-quality advice.
How to test free chlorine in your shower water
Use free-chlorine test strips and follow the manufacturer's instructions. Comparing water before and after installation can give you a practical baseline.
- One. Fill a glass from the shower before you fit anything.
- Two. Fit the filter and run it for a minute.
- Three. Fill a second glass.
- Four. Read both against the colour chart in the same light, and film it without cutting if you want it to count for anything.
Record both readings under the same conditions so you can compare the result clearly.
