Things To Consider Before Buying a Kitchen Sink For Hard Water

Bowl Size

There are mainly three different sizes when it comes to kitchen sinks — single oversized bowls, double bowls, and triple bowls. This, most of the time comes down to personal preference, but otherwise, you usually won’t need anything more than a double bowl.

Hard water doesn’t affect the bowl of your kitchen sink anyway if you use the right material, so you just have to pick the size that suits you the best.

If you need to multitask, you should pick the double bowl, but other than that, a single oversized bowl can work the best and is the easiest to clean.

Sink Material

Not all materials are resistant to hard water, and they can easily get stained or get corroded. But the most common materials that are good for hard water are stainless steel, granite, copper, composite, fireclay, and greystone.

These all look fantastic, so you can just pick any that fits your liking. However, some can be more expensive than others.

So if you’re going for a luxurious look, you can pick greystone, fireclay, granite, or composite, but stainless steel will work the best for most people.

Stainless steel and copper are the cheapest out of them all too, so they’re the most commonly used material.

Sink Type

There are tons of sink types out there, but undermount sinks are the most common ones. This is because they often work the best for kitchens too, especially for hard water.

In a nutshell, undermount sinks are installed with the kitchen countertop instead of being placed in a pre-cut hole inside the countertop.

Since they’re installed like this, there isn’t a rim between the sink and the countertop. This makes it more costly but also better looking. So depending on your preferences, an undermount sink can be excellent.

Faucets

If you live in a cold country or just prefer getting hot water out of your taps, you should definitely consider getting a hot-water faucet. These are installed underneath the cabinet and can provide water up to 190 degrees Fahrenheit.

Cooking can be much easier with this too since you’ll often need already heated or boiled water for various dishes.

However, hard water tends to accumulate more when you heat them up, so getting a softener with your faucet is highly recommended.

Wide Drainage Sections

One of the most important parts of a sink is the drainage, so you shouldn’t ever cheap out on them. Instead, try to pick a sink with wide draining sections since they make a bigger difference than you might think.

Difference Between Hard Water & Regular Water Use In Kitchen

As mentioned above, hard water is water with more minerals than your regular drinking water. This might sound harmless, but it can contain so many minerals that they’ll be harmful to your kitchen.

Some of the most notable minerals they contain are magnesium, lime, and calcium. This is why they aren’t the best for regular use in your kitchen, since they can easily react with other materials or chemicals.

One of the best examples of this is soap and other cleaning materials. When these come in touch with hard water, they can cause deposits in your sink, clog your drainage pipes, and they can stain your kitchen sink and faucet.

This makes hard water require much more maintenance than regular water when it comes to basic use in the kitchen. The best way to prevent this is by investing in different and more resistant materials for your sink itself.

Hard water stains usually look white or brown, and they’re not easy to get off either. You can also notice deposits on the openings or edges of your faucet, drain, and pipes.

This is the main difference between hard water and regular water in the kitchen. So if you want to prevent these changes or minimize them, get a resistant material for your sink, such as stainless steel or consider using a softener.

How to Deal with Hard Water Problems

Hard water can only create stains over a long period of time in your sinks. Stainless steel prevents your sink from getting hard water stains too, but at some point, you will get a few hard water stains.

So to prevent this, you should use a softener. A softener will remove as many unnecessary minerals as possible from your water, allowing you to have next to no chances of getting hard water stains.

Softeners can be a bit costly, depending on your sink, though. So even if you have a stainless steel sink with a softener, you should learn how to keep it clean from any hard water stains or deposits, especially on the faucets. Here’s a step-by-step guide to removing them from the faucets —

  1. Soak a clean cloth in vinegar and cover the faucet with it. Make sure to cover the areas with visible hard water deposits well.
  2. Let the cloth sit for 30 to 60 minutes. Leaving it for an hour will give the best results.
  3. Take the cloth off and get a non-scratch sponge to prevent scratching your faucet, and scrub the entire faucet. Make sure to rub well on the white/brown hard water stain areas.
  4. Rinse the area thoroughly with water.
  5. Repeat these steps if the stains don’t go away instantly, or leave the cloth there for longer.

These are all steps to clean your faucet. A softener will prevent most stains on your kitchen sink itself, but if it doesn’t and you get hard water stains, you can follow the same steps above to keep your sink clean.

Kitchen Sink Material For Hard Water

There are tons of options when it comes to good kitchen sinks, but you might be wondering what kind of sink is best for hard water. The most obvious choice is stainless steel since it’s usually the cheapest option and can work best for more people. But here’s an in-depth list of the best kitchen sink materials

Stainless Steel

Stainless steel kitchen sinks can last 15-30 years. They’re resistant to scratches and stains and are easy to clean. On top of that, they are usually cheap, too.

Cast Iron

Cast iron is much better than stainless steel, but it does come at a higher price.

However, cast iron kitchen sinks can last for 20-30 years and are much more resistant to hard water than stainless steel. It’s hard to get dents or chips on these sinks too, and they’re easy to clean and are one of the most durable kitchen sink materials.

Quartz Composite

If you’re willing to spend some money, quartz composite sinks can be the best possible option for your kitchen, especially for hard water. They look luxurious, and they can last for 40-50 years!

They’re also resistant to stains, dents, and scratches, and are extremely easy to clean. Along with that, it’s fully antimicrobial, making it perfect for any kitchen.

So overall, stainless steel is the best cheapest option, cast iron is the best mid-range option, and quartz composite is the best material for a sink.

Final Thoughts

Hard water is a common problem in the kitchen. This is why using the best kitchen sink for hard water is so important.

Hopefully, now you have a good idea to choose the right sink for hard water. There are tons of options to pick from, but stainless steel ones can be the most durable and the cheapest.

But as a final note, I’d highly recommend you keep your faucet aerators clean. Although these aren’t visible, they’re the most prone to getting hard water stains, and they can affect the flow of the water.
