About Sink Strainers

Sink strainers are available in various styles and finishes—including chrome, stainless steel, nickel, and bronze. They are available at home centers and plumbing supply stores ranging in price from under $10 to over $60 each. Be sure to buy a quality strainer that’s made from stainless steel or brass for your sink.

Nothing is more annoying than a strainer basket that doesn’t remain open when you want it, which is most of the time, or one that doesn’t close easily to hold water in the sink. Before buying a new strainer for your sink, read the customer reviews and rating of models you are interested in on home center websites.


  1. I removed excess putty from the bottom of the sink opening and strainer. However as I tightened the locknut washer some putty eventually came out between the sink and the top of the rubber gasket… when I used less of the putty (an earlier attempt) there wasn’t enough and water eventually leaked from that area. This might fail, too. Frustrating.

    • Katherine,
      Plumber’s putty should squeeze out all around the sink strainer when you tighten up the locknut. A little of the putty may continue to ooze out for a time, but it can be easily wiped off.

  2. Yes, I understand the putty squeezing out around the top of the strainer, but should any come out under the sink, around the gasket(s)?

    • Katherine,
      Putty didn’t squeeze out around the gasket under the sink when I replaced mine, but it should still seal OK if it does.
