What the AI looks for in Kitchen Drains & Strainers

Opening size
Standard kitchen basket strainers fit an opening of about 3-1/2 inch with a 1-1/2 inch outlet Bathroom drains and some bar sinks are smaller and need different parts.
Body material
Choose a solid stainless or brass body and locknut over plastic or thin stamped steel The locknut and threads take the most stress, and cheap ones crack or strip.
Thread length for thick sinks
Cast iron, fireclay and composite sinks need a strainer with a longer threaded body Short threads won't reach the locknut through a thick sink deck.
Stopper style
Options include a post-style basket, a twist-lock stopper, or a press-down spring stopper These determine how easily you can seal the sink to soak dishes and empty the basket.
Sealing method
Use plumber's putty or the supplied gasket; use stain-free putty or silicone on stone or composite sinks Regular putty can stain porous materials.
Disposal side
Use the disposal brand's own stopper or splash guard, not a basket strainer Disposal flanges have their own size and design.

Brands that matter

  • Kohler: Its Duostrainer line is a common higher-quality basket strainer.
  • Moen: Strainers in faucet-matching finishes.
  • Oatey: Basic replacement strainers and plumber's putty.
  • Keeney: Widely available strainers and tailpieces.
  • InSinkErator: Stoppers and splash guards for its own disposals.
  • Kraus: Strainers designed for its sinks.

What to avoid

  • Plastic locknuts on a sink that gets heavy use
  • Regular plumber's putty on natural stone or granite composite sinks

Questions

Will a basket strainer fit my garbage disposal?

No. The disposal side uses the disposal's mounting flange. Buy a stopper made for that disposal brand.
