Shower water, often referred to as tap water, is indeed what you get when you turn on the shower faucet. Tap water is a general term for water that flows through your plumbing system, whether it’s used in your kitchen sink, bathroom sink, or shower. This water is typically sourced from various locations, including rivers, lakes, and underground aquifers. It goes through a purification process to ensure it meets safety and quality standards.
Ever wondered why the water in your shower feels different from what comes out of your kitchen tap? The key to understanding this lies in the temperature. When you shower, the water often feels softer, and this is because it’s typically warmer than the cold tap water you use for drinking. Is Shower Water Tap Water?
The warmth of shower water comes from your water heater, which heats up the tap water before it reaches your showerhead. This not only makes your shower more comfortable but also reduces the risk of scalding from hot water. Tap water quality can vary based on local water treatment processes and the presence of minerals, which can affect its texture and taste.
Should I Shower With Filtered Water?
Before diving into the details of shower water sources and safety, let’s address a common question: should you shower with filtered water? The answer depends on several factors, including your location, personal preferences, and health concerns.
| Factors to Consider | Details |
|---|---|
| Water Quality | If tap water has impurities or a strong chlorine odor, consider using a water filter to improve water quality. |
| Skin Sensitivity | Sensitive skin may benefit from filtered water to reduce skin irritation caused by harsh water chemicals. |
| Environmental Concerns | Using filtered water can minimize the release of harmful chemicals into the environment, affecting aquatic life. |
| Cost Considerations | Installing a water filter for your shower is an additional expense; weigh the benefits against the cost. |
Where does a shower water supply come from?
To understand whether shower water is tap water, we first need to consider the source of the water that flows into our bathrooms. The water supply to your shower typically comes from the same source as your tap water, but the journey it takes may involve some differences.
Municipal Water Supply
In most urban and suburban areas, shower water is sourced from the municipal water supply. Here’s how it usually works
- Water Treatment Plant Water is sourced from lakes, rivers, or underground reservoirs and undergoes treatment to remove impurities, bacteria, and other contaminants.
- Distribution Network The treated water is then distributed through a network of pipes to homes and businesses.
- Water Main The main water pipe entering your house delivers water to your plumbing system.
Well Water
For homes in rural areas or locations without access to municipal water, well water is a common source for both tap and shower water
- Groundwater Source Wells tap into underground aquifers to access groundwater.
- Well Pump A well pump brings the water to the surface and directs it to the plumbing system.
Reasons shower water isn’t safe to drink
While the source of shower water is typically the same as tap water, there are several reasons why shower water may not be safe to drink. Let’s explore these reasons in more detail.
You Have an Old Home with Old Pipes
Older homes may have plumbing systems with pipes made from materials like lead or galvanized steel. These materials can corrode over time, potentially introducing contaminants into the water. Drinking water from these pipes is not recommended, and the same holds for shower water
Your Shower Water Sits in a Water Storage Tank
In some homes, particularly those with low water pressure, water storage tanks are used to ensure a steady supply of water. Water stored in tanks can become stagnant and may be exposed to air and bacteria. This can result in a less-than-ideal water quality for drinking.
Your Shower Head is Old, Dirty, or Stained
Showerheads can accumulate mineral deposits and microbial growth over time, affecting the quality of the water that flows through them. These contaminants can be harmful if ingested, so it’s advisable not to drink shower water in such cases.
Your Shower Water Runs Through a Water Heater
Many homes have water heaters that heat the water before it reaches the shower. These devices can introduce various issues
- Heater Contaminants If the water heater is old or not well-maintained, it might introduce contaminants into the water.
- Temperature Water heaters heat water to high temperatures, which can cause chemicals to vaporize, making shower water less suitable for drinking.

Health Effects of Showering with Unfiltered Water
While shower water is not intended for consumption, it’s important to consider the potential health effects of showering with unfiltered water. Even though you’re not drinking the water, your skin and respiratory system can be affected.
Sensitive Skin
Showering with unfiltered water, especially if it contains chlorine or hard water minerals, can have adverse effects on your skin
- Skin Dryness Chlorine and hard water minerals can strip your skin of its natural oils, leading to dryness and irritation.
- Eczema and Dermatitis Individuals with skin conditions like eczema or dermatitis may experience flare-ups when exposed to unfiltered water.
Respiratory Conditions
The steam and mist created during a hot shower can be inhaled into your lungs, potentially causing issues if your shower water is not filtered
- Asthma Chlorine fumes in shower water can trigger asthma symptoms in sensitive individuals.
- Respiratory Irritation Irritants in unfiltered water can lead to throat and lung discomfort.
FAQ’S
Can showering with unfiltered water worsen allergies?
Yes, unfiltered shower water can exacerbate allergy symptoms due to the presence of allergens and irritants.
Can I reduce the health effects of unfiltered shower water without installing a filter?
You can try shorter and colder showers, as this minimizes your exposure to potential contaminants.
Are there any DIY methods to improve shower water quality?
Some people use vitamin C or activated carbon shower filters as a DIY solution to reduce chlorine and impurities.
How can I tell if my tap water has high chlorine levels?
You can have your water tested by a local laboratory or use a chlorine test kit, readily available at hardware stores.
Conclusion
In conclusion, shower water is, in essence, tap water drawn from the same source. The distinction lies in the temperature and the potential impact of water heating mechanisms. The processes of heating and delivery can introduce variables that may affect the quality and safety of the water.
Regular monitoring, adherence to water safety guidelines, and responsible water heater maintenance are essential steps to ensure that the water you use for drinking, bathing, and other household activities remains safe and of high quality. By staying informed and taking appropriate measures, you can enjoy peace of mind in knowing that your tap water and shower water are both sources of clean, safe water.
