Louisville tap water is treated and regulated. It can still smell like a pool when you turn on a hot shower. That smell is usually the disinfectant Louisville Water uses to keep the system clean, not a sign that the pipes failed overnight.
If the odor shows up at every cold tap and does not fade as the water runs, it is coming in with the supply. If it is only at one fixture, or it disappears after a minute, start with the drain or a stagnant line before you shop for equipment.
What you are smelling
Louisville Water disinfects with chloramine (they also call it total chlorine). It is related to the chlorine used in pools, at a much lower dose. Hot water in a closed shower releases that odor into the air faster than a glass at the kitchen sink, which is why the bathroom is where most people notice it.
A glass of cold water might taste a little medicinal or flat. Coffee and tea pick it up too. None of that means the water is unsafe. It means the disinfectant is doing the job it was added to do, and some homes want that taste and smell gone.
A simple check, the same one Louisville Water publishes: run cold water for a minute, fill a clean glass away from the sink, and smell the water, not the drain. If the glass smells like chlorine or medicine, it is the water. If the glass is fine and the sink still smells, it is the drain.
What does not fix it
Leaving a pitcher on the counter, boiling a pot, or running the tap longer will not do much. Chloramine is more stable than free chlorine. It does not air out the way pool water does.
A fridge pitcher can take the edge off one glass. It does nothing for the shower, the laundry, or the rest of the house. A water softener does not remove disinfectant taste either. Softening is for hardness and scale. If spots and soap film are the complaint, that is a water softener conversation, not this one.
We do not sell a water test as the next step, and we do not treat city water as if it were unsafe.
What actually helps
Match the fix to where the smell bothers you.
Every tap, including the shower. A whole-home water filter sits at the point of entry. Showers, laundry, ice maker, and every faucet see the same treated water. That is the right tool when the pool smell hits you in the bathroom. Louisville homes on city water usually start here. Read how that equipment how a whole-house water filter works, or the Louisville whole-home filter page if you want the local version.
Just the glass you drink. Reverse osmosis is kitchen equipment. It has its own faucet. It is not a whole-home filter and it will not change the shower. People pick it for coffee, cooking, and fewer cases of bottled water. Tank and tankless options are on the drinking water systems page. For a Louisville kitchen specifically: reverse osmosis in Louisville.
Both. If the shower smell and the drinking glass both bother you, that is a filter plus a kitchen RO, not one tank that claims to do everything. Whole-home systems is the pairing page.
Well homes are a different conversation. Sulfur, iron, or sediment is not chloramine. If that is what you smell, say so on the call so nobody quotes a city filter for a well problem.
How to decide in one conversation
You do not need a technician at the house to sort this out.
- City or well.
- Smell at every tap, or only in the shower, or only in the glass.
- Scale and soap film as a separate yes/no. That is the softener, not the filter.
From there the quote is a whole-home filter, a kitchen RO, both, or neither. Call or text 502-865-9330, or quote a whole-home chlorine filter.
