Advantages of Cast Iron Kitchen Sinks

There are many advantages to choosing a cast iron kitchen sink for your home. They remain popular in the design world simply because of their durability and how easy they are to maintain. Most cast iron kitchen sinks have a layer of porcelain enamel over the cast iron, which gives them an extremely durable and hard surface.

The main advantages for choosing cast iron kitchen sinks include:

  • Easy to Clean – Their smooth and glossy finish is perfect for hiding water spots and streaks.
  • Retains Heat – Cast iron is known for how it retains heat very well, which is a huge benefit when you’re washing many dishes or pots and pans by hand.
  • Available in an Array of Colors – It’s incredibly easy to make a style statement when choosing to add a cast iron kitchen sink to your home, plus they serve an efficient purpose.
  • Lasts a Lifetime – Cast iron kitchen sinks can last a really long time, and most manufacturers offer lifetime guarantees or lifetime limited warranties.
  • Authentic Vintage Sink – If you love vintage pieces, then adding a cast iron kitchen sink to your space will give you the most authentic vibe and look.
  • Materials Used – You will find that many of the new models for cast iron kitchen sinks are made from recycled and reclaimed content, which is fantastic since that makes them an environmentally-friendly choice.
  • Easy to Refurbish – The porcelain coating on most cast iron kitchen sinks can be refinished if necessary.

Keep in mind that even though cast iron kitchen sinks are known for their durability, the enamel coating can crack or crack if you drop something hefty on it. You’ll want to make sure that you are careful when washing heavy pots and pans. It doesn’t happen often, but it can happen.

If you experience a chip, the cast iron’s black surface might be exposed and therefore begin to rust. Make sure you pay attention if this happens and immediately contact the manufacturer since most cast iron kitchen sinks have a lifetime warranty.

These types of sinks are also susceptible to some stains and might be difficult to remove. However, by using a little baking soda and some arm muscle, the stains should quickly come off. Due to the heaviness of cast iron kitchen sinks, you’ll want to make sure you are using a sturdy countertop or cabinet to support the sink.

Types of Cast Iron Sinks

When choosing a cast iron kitchen sink, you should first decide what type of cast iron sink your space can accommodate. These are the different types of cast iron kitchen sinks you can choose from:

Drop-In Style – The cast iron kitchen sinks designed to just drop-in are considered the easiest type of cast iron kitchen sink to install. However, they may require more caulk than other varieties to seal the gaps between the countertop and the sink.

Under-Mount – The under mount cast iron kitchen sinks are known to be more challenging to install and also come with a higher price tag.

Apron Style aka Farmhouse Style – The cast iron kitchen sinks that come with the apron-front style, which typically features an exposed, drop-down front, normally require a particular type of cabinet that is designed for accommodating this type of cast iron kitchen sink.

Regardless of the type of cast iron kitchen sink you choose, you need to keep in mind that you may have to modify your countertop’s design to accommodate this type of cast iron kitchen sink.

Self-Trimming vs. Regular

The self-trimming cast iron kitchen sink will overlap your cabinet face and hide the cabinet’s cut-out, which in turn makes the installation process exceptionally easier. Both contractors and cabinet makers are fans of the self-trimming cast iron kitchen sinks. They never have to worry about having a cabinet face with a ‘perfect’ cut-out; the self-trimming cast iron kitchen sink easily covers any miscalculations or an uneven cut.

In fact, the self-trimming cast iron kitchen sink will easily hide any blemishes from the installation process, including the cabinet cut-out.

Undermount vs. Overmount

If you are trying to decide between an undermount or overmount cast iron kitchen sink, you’ll need to consider your countertop material before choosing the best type of sink for your space. Whether an undermount or overmount cast iron kitchen sink is right for you will depend on things like your budget and if it’s going to be a DIY project.

While most undermount cast iron kitchen sinks are predominantly preferred for appearance, an overmount can be a much better investment in longevity for some countertop materials, such as wood. However, the undermount cast iron kitchen sinks are mainly loved due to their smooth appearance and how they can complement different kitchen decors, such as stone or other solid surface countertops.

Below are the most significant differences between undermount vs. overmount sinks.

Undermount Sinks

The undermount cast iron kitchen sinks have this name mainly because they sit right under your counter, making the edge of your sink sit below the countertop’s level. You will generally find three different types of undermount installation:

  • Positive Reveal – Counter stops right before the edge of your sink, creating a ledge.
  • Negative Reveal – Counter can overhang the sink by a little.
  • Flush – Your sink edges and counter are entirely aligned.

Below are some of the pros and cons for choosing an undermount cast iron kitchen sink:

Pros:

  • Provides Clean, Attractive Lines
  • Acquires Slightly More Counter Space
  • Easy to Clean Messes Directly into Your Sink
  • Are Typically Deeper for Cleaning Large Pans or Pots

Cons:

  • More Expensive
  • Recommended Professional Installation
  • Bigger Risk of Chipping the Counter Edge
  • Must Be Perfectly Sealed to Avoid Water Getting Into Gap Between Counter and Sink
  • Work Best With Granite and Other Types of Stone or Water-Resistant Composite

If your kitchen countertop is not water-tight (ex: wood), you should not choose undermount cast iron kitchen sinks. We strongly recommend a solid surface countertop for undermount cast iron kitchen sinks.

Overmount Sinks

These types of sinks are known as drop-in or top-mount and have a lip that sits just above the countertop and covers a minimal area.

Pros:

  • Easy DIY Project
  • Typically More Affordable (Even when Hiring a Pro to Install)
  • Best for Porous Countertops and Ones that Need Protection (Ex: Butcher Block)

Cons:

  • Raised Lip can Interrupt the Countertop Level Surface
  • Often Collect Water and Crumbs Around Edges

Which is Better Cast Iron or Stainless Steel Sink?

Both cast iron kitchen sinks and stainless steel sinks have a pretty long lifespan. However, the stainless steel sink will probably only last between 15 up to 30 years, while cast iron kitchen sinks last well over 25 to 30 years and often last a lifetime. So if you’re looking for longevity, then the cast iron kitchen sinks definitely last longer than the steel ones.

Keep in mind that cast iron kitchen sinks can be restored or refinished to last a lifetime. And, of course, the more the sink is maintained, the longer it will last. Cast iron kitchen sinks are also more durable and can handle more wear and tear through the years vs. the steel sinks getting pinged or rusty over time.
