How to Choose The Best Kitchen and Bathroom Faucets for Hard Water?

When choosing faucets, we often focus on their aesthetic appeals and functionality. Many don’t realize that hard water in their local area will cause problems to their plumbing system. Hard water is high in mineral content, which causes very hard chalky deposits to develop inside the pipes.

Before you get started on your kitchen sink or bathroom faucet research, let’s first go over what hard water is, and why it’s important to have a kitchen faucet that is suited for this type of water.

You need a good faucet for your kitchen sink if you have hard water. Hard water causes problems with faucets. A good faucet will last a long time in the face of hard water.

What is Hard Water? Hard water is regular water only with high mineral content inside. In contrast with soft water, hard water has a much higher mineral content. Hard water is formed when water percolates through deposits of limestone, chalk, or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates, and sulfates. All these minerals dissolve in the water, through which they come into our homes. Water with a high mineral content can be seen as white traces on places where water has been. After the water evaporates, mineral traces can be seen.

Over time, the crusty deposits cause damage to faucets, appliances, and pipes. Detergents and soaps work less effectively if tap water is high in mineral content.

By some estimates, appliances work half as long if their internals is affected by a mineral build-up. Hard water often causes unsightly yellowish stains in bathtubs, showers, and sinks. Glass showers will slowly look more opaque due to the accumulated hard water stains.

If your skin is dry and easily irritated, it could be due to prolonged use of hard water. Also, hard water doesn’t rinse off shampoo well, which also causes dryness of your hair. Long-term consumption of hard water is also a risk factor for kidney dysfunction and various cerebrovascular problems. For these reasons, you need the best faucets for hard water, especially for your kitchen and bathroom.

Here are factors to consider:


An appropriate finish keeps faucets more resistant to hard water stains. The accumulated stain will be more difficult to remove, if you neglect regular clean-up, especially if your faucets are further stained by salt, soap, and dirt.

If you are looking for the best faucet finish for hard water, the silvery matte of brushed nickel should be an option to consider. Although abrasions created by wire brush take away its luster, the brushed nickel finish will make staining far less visible. Another type of finish is called a satin nickel, which goes through the electrolysis process. It’s shinier than brushed nickel, but still, resists hard water staining very well.

If your bathroom and kitchen have a more colorful or warmer design, you may choose brushed brass or white ceramic faucets. With the right finish, you may clean the faucet less often.


Best bathroom faucets for hard water should have an aerator to ensure reliable water pressure. Mineral build-up within the pipework may cause low water pressure, which is inconvenient when you are taking a bath or showering. If you have good water pressure, the aerator still helps to conserve water.

Magnetic docking should make faucets easier to use in the sink, due to a more flexible movement capability. The dual-function spray head allows you to switch between an aerated stream and a more powerful spray easily.


Because high minerals in tap water may affect your health, the best kitchen faucets for hard water should include built-in filters. These filters will contribute to reducing the excess mineral content in water, such as calcium, magnesium, and carbonates.

With this water filter you’ll get a system that balances the four elements you need to block:

  • Chlorine
  • Pharmaceuticals
  • Pesticides
  • Dirt
  • Odors

It helps control scale buildup, plus restores what your hard, chemical-filled water did to your hair, skin, and nails!

Best kitchen faucets for hard water should also include filters to remove sediment, due to higher levels of fine clay and soil. Although it doesn’t pose a health risk, slightly brackish well water will not taste as good. Be sure to choose faucets with filters listed as nano or ultra to get rid of potentially dangerous pathogens.

For better results, you should have a water softener installation at home to eliminate magnesium and calcium through the ion exchange process. A water softener system usually has a mineral tank to capture mineral ions, a control valve to measure the volume of water flow, and a brine tank to restore the positive charge of the resin beds.

High-quality components

Some bathroom and kitchen faucets have more complex internals, including electronic circuits, if they have sensors, LED displays, and touchless buttons. The lifetime of a faucet could be reduced by a few years if it’s not designed to work with hard or well water.

Faucets should work properly for their expected lifetime, despite the gradual build-up of minerals. As an example, ceramic sealing coats can better withstand slow degradation due to hard water.


Undoubtedly, bathroom and kitchen faucets designed for hard water are more expensive, due to better finish, higher quality internal components, and more features. However, more expensive faucets are not necessarily better than cheaper ones.

Set a budget, so you know what faucets are available within your price range. Compare faucet models to know more about their quality and durability. It’s also helpful to read user reviews to make sure whether these faucets are as functional and reliable as advertised.


It’s recommended to choose faucets that are not only good in your bathroom and kitchen but can also withstand hard water properly. An overly complicated faucet with tight tolerance is usually more vulnerable to hard water deposits. If there’s enough space, you should choose faucets with tall spouts for more flexible uses. If the spout has a short reach, it may not extend adequately into the sink bowl and may cause splashes.

To minimize the risk of leaks or dribbles, you should choose faucets with pull-down sprayers, instead of those with a side sprayer.

In conclusion

When you’re looking for faucets to deal with hard water, consider choosing a water filter also. Furthermore, keep your focus on aesthetic appeals and functionality. Hard water will cause problems to the plumbing system, and it is up to you how to solve those problems. Choose only the best faucets for hard water, which doesn’t mean you need to spend a fortune on faucets. Whether you are looking for kitchen faucets or bathroom faucets, check what you can find in your budget.

We hope you had a good time reading about hard water and all the troubles it brings. That is why it is so important to choose the best faucet for hard water.
