Cast Iron Sinks: Their Pros and Cons

Aramenta Waithe

Cast iron and stainless steel are two of the most popular materials for manufacturing kitchen sinks. Each material lends a distinctive look to the kitchen. Cast iron, while offering a variety of color choices, also has its drawbacks.

Understanding the pros and cons of cast iron sinks can help you decide whether cast iron is the best material for your sink.


Unlike stainless steel, cast iron gives you the ability to select the sink color of your choice. Cast iron sinks have a glossy enamel coating that not only resists wear and makes water spots less apparent, but also comes in a variety of colors. Whether your dream kitchen is decked out in celadon green or a deep, kingly red, you can color coordinate with a cast iron sink.


Cast iron sinks are especially durable, and if you take care of yours, there is no reason why you shouldn't expect it to outlive you. However, the enamel coating is not resistant to scuffing or chipping. You have to take care not to clean the sink with abrasive cleaners or bump it with heavy objects, as you could damage the coating. If any chips or scratches expose the cast iron beneath, the sink will begin to rust. Although you can repair damaged enamel, the sink may not look as nice as it once did.


The weight of cast iron sinks is both a blessing and a curse. While the weight contributes to the durability of the sink, you may need to make certain design decisions with your kitchen counter to make sure that the sink will have the support it requires. Additionally, you will probably be unable to install the sink without help, as you might be able to with a stainless steel model. Be prepared to ask for help or hire someone to perform the installation for you.


If you purchase a new filter for your drinking water and want to install a second faucet after putting the sink in, you may find it difficult to drill the hole for the second faucet. Drilling a hole could result in damage to the enamel, which could lead to rust and eventually force you to replace the sink. If you think that you might want to install a second faucet eventually, it is best to purchase a cast iron sink with the second hole pre-drilled.
