A sink strainer is the removable basket or filter that sits in a sink drain and traps food, peels and grit while letting water flow through. It protects pipes and septic systems from clogs and is the cheapest way to keep a kitchen running smoothly. This page focuses on the strainer itself; it is part of our wider sink hardware section.
The collection holds about 70 strainers and filters, and every item listed is in stock at the moment. List prices run from under $10 to about $40 per listing, and most fall between roughly $16 and $27. Many listings are two-packs, three-packs or combo sets, so compare the unit count rather than the headline price. Stainless steel and silicone are the main materials, with a few disposable mesh filters.
Kitchen Sink Strainer Basket Types
Most shoppers are matching a replacement for a worn basket, so it helps to know the main designs:
- Deep basket with post: the classic design with a center knob. Lift it to empty; some models twist or press down to seal.
- Shallow wide-rim strainer: sits higher in the drain and covers more of the opening, which suits sinks with a garbage disposal.
- Fine mesh basket: a sink mesh strainer with small perforations catches coffee grounds and rice that slip through standard holes.
- Stopper combo: a two-in-one basket adds a rubber seal so the same part strains or holds water.
- Flat silicone cover: rests on top of the drain rather than inside it and flexes to fit several sizes.
- Disposable filters: disposable filters use mesh bags you throw away with the scraps, handy for heavy cooking or shared kitchens.
Stainless Steel vs Silicone Strainers
A stainless steel sink strainer is rigid, rust resistant and handles boiling water and dishwasher cycles. It holds its shape for years and looks clean in a steel sink. The downside is that rigid baskets must match the drain size closely.
A silicone sink strainer is soft, quiet against the sink and easy to turn inside out for cleaning. It tolerates hot water well and grips the drain, but it can stain from tomato sauce or turmeric and is less sturdy under heavy pots. Many households keep one of each: steel for daily use, silicone for the bathroom or a second sink.
Getting the Right Fit for Your Drain
- Measure the opening across the top of the drain, not the basket you are replacing, which may have worn or been the wrong size.
- Check the depth if you have a garbage disposal or a deep drain body; a tall basket may not sit flat.
- Look for "universal" or a stated diameter in the listing, and compare it with your measurement.
- Check the rim. A wider lip stops the basket from dropping through and keeps scraps from slipping around the edge.
A bathroom basin is a different size altogether; smaller covers and hair catchers for basins are grouped on our sink drain parts page, along with full drain assemblies.
Replacing the Strainer Body Under the Sink
Dropping a new basket into the drain needs no tools. If the whole strainer body under the sink leaks, though, you will need to replace the assembly. Shut off the water, loosen the slip nut on the tailpiece, unscrew the large locknut beneath the sink and lift the old body out. Clean the opening, seal the new flange with plumber's putty or the gasket provided, then tighten the gasket and locknut from below and reconnect the pipe. For stone or composite sinks, use a silicone sealant instead of putty to avoid stains. Run water for a minute and check for drips before putting things back under the sink.
Daily Care That Keeps Water Moving
- Empty the basket after each meal so scraps do not sour or block flow.
- Scrub steel and silicone with dish soap and a small brush; most go in the dishwasher.
- Soak stained silicone in warm water with baking soda.
- Replace the rubber seal on stopper combos when the sink no longer holds water.
- Keep a spare basket so you can swap one into the dishwasher without leaving the drain open.
Sink Strainer FAQ
What is the best material for a kitchen sink basket?
Stainless steel is the most durable choice for daily kitchen use because it resists rust and heat and keeps its shape. Silicone is a good second option where you want a soft, quiet strainer that is easy to clean.
Will any strainer fit my kitchen sink?
Most US kitchen sinks share a standard drain opening, so many baskets fit, but depth and rim width vary. Measure your drain and check the stated diameter, especially if you have a garbage disposal.
Do fine mesh strainers slow down drainage?
Slightly, because the smaller holes catch more debris and can fill faster. Emptying the basket regularly keeps water flowing; for heavy cooking a wider-hole basket may drain faster.
Can I use a strainer in a bathroom sink?
Yes, but bathroom drains are much smaller than kitchen drains. Use a small cover or hair catcher made for basins rather than a kitchen basket.
How often should I replace a strainer basket?
Steel baskets last for years; replace them when the mesh bends, the post breaks or the seal stops holding water. Silicone strainers may need replacing sooner if they tear or stain heavily.
