Reusing and recycling items in your kitchen is not only good for the environment, it can also help you save money. Your kitchen sink is one item that has many reusable and recyclable components. Here are some tips for recycling or reusing your kitchen sink.

Assess Your Current Sink

The first step is to take a close look at your existing kitchen sink. What is it made of? Stainless steel, enamel, porcelain, and cast iron are all materials that can often be reused or recycled. Make note of the size, shape, color, and condition. If it is still in good shape with no cracks, chips or stains, your sink may be suitable for reuse.

Donate or Sell

If you are remodeling your kitchen and replacing your sink, consider donating or selling your old sink rather than sending it to a landfill. Stainless steel and enamel sinks are especially desirable for reuse. You can donate it to organizations like Habitat for Humanity or post it for sale on sites like Craigslist and Facebook Marketplace. Be sure to advertise the dimensions, color, and any special features.

Repurpose In Your Home

A kitchen sink can be repurposed for a variety of uses around your home. Turn it into a potting sink in the garden, use it for washing pets outside, make it into a unique planter, or use it as a laundry sink in the basement or garage. Be creative and find a way to extend the life of your sink.

Recycle the Materials

If your sink is cracked, badly stained, or has other damage, the best option is to recycle it. Here are some recycling tips for common sink materials:

Stainless Steel

  • Remove fixtures, strainers, and other attachments.
  • Take the sink to a steel recycling center. Be sure to call ahead to verify they accept stainless steel sinks.
  • The sink will be melted down and turned into new steel products.


  • Porcelain sinks can be crushed and recycled as landfill cover.
  • Contact your local landfill to see if they accept porcelain for recycling.
  • Remove all metal or plastic fittings before recycling porcelain.

Cast Iron

  • Cast iron sinks can be taken to a metal recycling facility.
  • Be sure to remove any attached fixtures or strainers first.
  • The cast iron is melted down to make new metal products.

Enamel Coated Cast Iron

  • The enamel coating prevents standard metal recycling.
  • Remove enamel layer by sanding or using paint stripper.
  • Once coating is removed, cast iron portion can be recycled.

Recycle Sink Parts and Fixtures

Don’t forget that the fixtures, strainers, handles, and attachments on your sink may also be recyclable depending on the materials:

  • Metal strainers, handles, etc can be taken to a scrap metal recycling facility.
  • Plastic attachments may be recyclable – check codes on plastic pieces to verify.
  • Rubber gaskets can sometimes be recycled with scrap rubber.

How to Remove an Old Sink

When taking out your kitchen sink for reuse, repurposing or recycling, be sure to remove it properly:

  • Turn off hot and cold water supply lines and disconnect the drain pipe. Wear eye protection.
  • Remove supply lines, drain pipes, p-traps and any other plumbing connections.
  • Uninstall any attached counters, backsplashes or countertop material around the sink.
  • Use caution when handling sink – stainless and cast iron especially can be very heavy. Consider asking someone to assist you.
  • Once removed, thoroughly clean the sink with soap and water to prepare it for its next purpose.

By taking time to either reuse, repurpose or recycle your kitchen sink, you’ll keep it out of the landfill and extend its useful life. Examine your sink to determine if it can reused as-is, repurposed for other uses, or recycled through scrap metal or porcelain recycling programs in your area.
