Best Cast Iron Sink 2020 Buying Guide

As mentioned earlier, a good cast iron sink should last you for a long while and yes, it is durable. But do keep in mind that its enamel coating can chip due to rough treatment. That being said, it continues to hog the headlights for all the right reasons. Here are a few things that you may want to keep in mind with regard to cast iron sinks.

  • Weight:

Cast iron sinks primarily consist of a heavy metal alloy as the base with an enamel coating on the top. It is this enamel coating that gives the sink its neat glossy finish and also one that makes it possible to get the sink in various colours and shades. That being said, it can be quite heavy – more so than most of the other sink types in the market. So you may want to keep that in mind when you opt to purchase a cast iron sink for your kitchen.

  • Installation:

When it comes to cast iron sinks you can either go for a top mount or an under mount style. It is basically your own preference but you should know that a top mount does not require much effort on your part. Since the sink is quite heavy, it can be a challenge to do an under mount. Under mount sinks are not impossible but just that they may require additional fixtures at the bottom to brace up the sink. It is a good idea to call in the professionals to install your under mount sink so that it continues to function seamlessly and effectively.

  • Cost:

This is something that you may want to carefully weigh when choosing to purchase the best kitchen sink. Typically, cast iron sink prices often range from $400 to $600 and some of the latest models may even be pricier than that.

Maintenance tips for cast iron sinks:

Maintaining cast iron kitchen sinks must be easy, right? Well, the enamel surface of a cast iron sink makes it easy, compared to other types of sinks but that being said, you would still be required to take care of your sink and here are a few maintenance tips to help you do just that.

  • To clean your cast iron kitchen sink, all that is required is some warm water and a gentle scrub and that should take care of most of the stains and particulates. But you can also use a gentle non-abrasive cleaner to get rid of persistent stains or particulates.
  • Do not store your tea or coffee grounds in your enamel covered sink as it can easily stain the same. Getting rid of this stain may not be possible with a simple warm wash but you may require some deep cleaning agents with some heavy scrubbing on your part. Tip: Avoid storing your tea or coffee grounds for long, in your cast iron sink.
  • Try not to drop heavy implements in your sink. Granted that the enamel coating has been applied under much pressure and is meant to be durable. That being said, if you do end up dropping heavy vessels in your sink, then it can chip and crack the enamel layer which can spoil the whole “look”. And if that happens, it is extremely important that you get these cracks and chips attended to right away so as to prevent the metal base from developing rust and damage.


These are some of the top ranking cast iron kitchen sinks in 2020, each stands apart on account of its features and functionalities. Do check out the lot and choose one that fits in with your idea of what you need for your kitchen as well as your current budget for the same.
