Enameled cast iron sinks have been a popular choice for kitchens for over a century, and for good reason. Here is an in-depth look at why enameled cast iron makes for such an attractive and durable material for kitchen sinks.

What is Enameled Cast Iron?

Cast iron sinks are made by pouring molten iron into a mold to form the basic shape of the sink. The cast iron is then covered with a glass-like enamel coating, which is bonded to the iron under high heat. This enamel coating makes cast iron resistant to scratches, stains, acids and impacts.

Enameled cast iron offers the strength and durability of cast iron along with a beautiful and hygienic glass coating that comes in various colors. The enamel also prevents rusting, unlike uncoated cast iron sinks.

Benefits of Enameled Cast Iron Kitchen Sinks

Long-Lasting Durability

The first benefit of enameled cast iron is its extremely long lifespan. Properly cared for, these sinks can easily last 50 years or more. The strong, thick cast iron body resists dents, cracks and warping from daily use. And the enamel coating prevents scratches and stains over decades of use. This makes enameled cast iron perhaps the most durable sink material on the market.

Heat Resistance

Another advantage of enameled cast iron is its resistance to high temperatures. Pots and pans fresh from the stove won’t damage a cast iron sink like they could a plastic or acrylic sink. You can safely empty boiling water or pull hot dishes straight from the oven into an enameled cast iron sink without worry.

Stain and Scratch Resistance

The glassy enamel finish of these sinks resists staining, etching and scratching better than other sink materials like stainless steel. Its non-porous surface won’t absorb stains from spills and cleans up easily. The enamel won’t etch or discolor from acidic foods like tomatoes. And it stands up well to scratches from cooking utensils over years of heavy use.

Attractive Appearance

Enameled cast iron sinks come in a variety of attractive colors like black, white, biscuit and almond. The thick, glossy enamel has a very attractive look and feel compared to other sink materials. And unlike stainless steel, the finish is chip and scratch resistant. So an enameled cast iron sink will maintain its beautiful appearance for decades.


Cast iron sinks tend to be quieter than sinks made of stainless steel or other thin metals. Their heavier construction absorbs noise and vibration better. So an enameled cast iron sink is less likely to cause clanking and clattering of dishes.

Variety of Styles

These versatile sinks come in a range of configurations, from classic farmhouse apron-front to modern zero-radius designs. This allows an enameled cast iron sink to fit any kitchen decor. And most brands offer accessories like drain boards, racks and strainers to customize your sink.

Disadvantages of Enameled Cast Iron Sinks

Heavy Weight

The main downside of cast iron sinks is their heavy weight, ranging from 50 to over 100 pounds. This makes installation more difficult, and may require cabinet reinforcement. Their weight also means they cannot be mounted on most granite or stone countertops.

Susceptible to Chipping

While durable, the enamel coating can chip from impacts with heavy cast iron cookware. Care must be taken to avoid such damage during everyday use.

Higher Cost

Enameled cast iron sinks typically cost more than sinks made of stainless steel or composite materials. But their extreme durability offsets the higher initial investment over the life of the sink.

Caring for an Enameled Cast Iron Sink

An enameled cast iron sink is easy to keep looking beautiful and performing at its best. Here are some care tips:

  • Use a mild abrasive cleaner to gently scrub away stuck-on foods or stains. Avoid harsh cleansers.
  • Rinse thoroughly after cleaning to remove any lingering abrasive cleaner or particles.
  • Towel dry after each use to prevent mineral deposits from forming. A squeegee also works well.
  • For tough stains, make a paste with baking soda and water and scrub with a soft brush or sponge.
  • Be gentle with cast iron cookware to avoid chipping the enamel finish. Use a pan protector when required.
  • Re-seal the enamel every year or two using a commercial re-sealing product to protect the finish.
