First and foremost, you need to understand that Fireclay Sinks & Iron counterparts are significantly different.

In simple words, there are tangible differences between the two.

And, the main difference between the two is the material used for manufacturing.

As the name suggests, a Fireclay sink comprises ceramic that is fired in a kiln.

On the other hand, cast iron stays by its name as it is made of a metal that is smithed in a forge.

If you’re looking for a sink that gives an aesthetic look & feel, then without any second thought, I can recommend you a Fireclay sink.

On top of it, these little beasts are lighter & easier to clean.

On the other hand, on durability, robustness, and longevity, a cast iron sink wins the race.

In spite of cast iron sinks being heavier, they perform extremely well against stains.

It would be completely wrong to say that a Fireclay sink is better than a Cast Iron sink and vice-versa.

Frankly speaking, both are good in their own sense and comes with their own sets of pros and cons.

My suggestion to all my readers would be to look for the sink that NOT only caters to your requirements but also falls well within your budget.

Trust me, the costliest sinks aren’t always the BEST, and cheapest counterparts aren’t always the WORST.

Fireclay Vs. Cast Iron Sink | Major Differences

The important parameters on which we would be having a discussion are as follows:

  • Material
  • Price
  • Durability
  • Installation
  • Stain Resistance


As said earlier also, the major difference between the two is material itself.

Fireclay is ceramic and Cast Iron is metal.

So, most of the properties & features of Fireclay will resemble ceramic.

Similarly, the properties of a Cast Iron sink will resemble a metal family.

Heavier & Bulkier

It goes without saying that a cast iron sink would be relatively heavier and bulkier as Iron weighs more than ceramic.

Another significant reason for a cast iron sink being heavier is the fact that it has a coating of porcelain for a sturdy and robust build.

So, let’s understand the pros and cons of being heavier and bulkier.

Pros: durable, robust, and long-lasting

Cons: Less portable, and tedious installation process


When it comes to customization, a Fireclay sink takes the lead.

In simple words, a Fireclay sink provides you a wide range of customization in both usages and shapes, thanks to its malleability feature.


Do I REALLY need to say, which of the two sinks is more durable?

Yes, you guessed it, RIGHT.

A cast iron sink is more durable as compared to a fireclay counterpart, thanks to its metal features.


Beauty is in the eyes of Beholder.

So, both the sink have a good appearance.

A cast iron sink will give you a manly look something similar to an industrial or rustic one.

On the other hand, a fireclay sink will have an aesthetic and soft look.


To be honest, none of the two is a good choice for someone who is on a shoestring budget.

Both fall in the “high-end” category.

An average cast iron sink would cost you in the range of $350 to $700.

However, the premium models are priced at $2500.

On the other hand, fireclay sinks would cost you roughly in the range of $500 & $1500.

And, the premium models are available at a whopping price of $2000 and above.


Durability is definitely an important buying parameter so let’s discuss it in detail.

In terms of enamels and colors on the sink, fireclay scores higher than a cast-iron counterpart.

If you hate painting sink again and again, then fireclay could be a better option for you.

Unfortunately, a cast iron sink could lead to chipping more frequently.

When it comes to longevity/lifespan, we’ve got a clear winner and it is none other than a cast iron sink.

In fact, with proper and regular maintenance a cast iron sink can last for years to come, approximately 35-40 years- a lifetime deal, isn’t it?

Trust me, fireclay sinks aren’t also much behind in the race, they have in general a lifespan of 20 years which is pretty awesome as well.

Lastly, enamels are far more prone to staining as compared to its counterpart.

A cast iron sink will deal with problems such as rusting and over-heating in a better and effective way as compared to a fireclay counterpart.


For many of our clients, ease of installation is a big deal and can be a make-or-break decision.

To be honest, both these sinks need a good amount of effort from the buyers when it comes to installation.

And, if you’re a first-time buyer, then a cast-iron sink can put you on your toes when it comes to installing it properly.

At times, you may need to contact an expert for a proper installation of a cast iron sink.

Also, an additional under mounting support is needed in case of a cast-iron sink to prevent it from falling.

The unique design and weight of a cast-iron sink require additional sink parts for complete and proper installation.

On the other hand, a fireclay sink is relatively easier to install and comes with a set of specific instructions that you need to follow while expediting the installation process.

Stain Resistance

To be honest, a stain is an issue for both Fireclay and Cast Iron sinks.

Let’s dive deeper to find out how they deal with it.

Cast iron sink stands tall against stain issues at least in the first 10 years if NOT later.

I’ve not seen or heard of chipping happening in the first 10 years.

Similarly, chances of chipping & scratching are minimal in the case of the Fireclay sink as well.

However, when it comes to dealing with rusting, Fireclay does a better job just because Cast Iron is more prone to rusting.

The good news is, you can avoid rusting by following some simple tips such as avoiding the use of caustic cleaners and abrasives.

In the long run, Fireclay will pick up the stains relatively faster.

The enamel present on cast iron sinks prevents the occurrence of staining.

On the other hand, Fireclay sinks are porous and don’t have a protective layer in the form of enamel.

As a result, your fireclay sink will sooner or later start showing a yellowish layer on its top because of sauces, stews, etc.
