How to find the right Kitchen Sink Accessories AI guide

What the AI looks for in Kitchen Sink Accessories

Sink hole and drain sizes
Kitchen sink drain openings are about 3-1/2 inch; deck accessory holes are about 1-3/8 to 1-1/2 inch; kitchen drain piping is 1-1/2 inch Almost every fit problem comes from mixing these up with bathroom sizes, which are smaller.
Sink material and thickness
Cast iron, fireclay and granite composite sinks need parts with longer threads than thin stainless sinks Strainer bodies and dispenser shanks sized for thin steel may not reach the locknut on thick sinks.
Finish match
Buy deck-visible parts in the same brand and finish as the faucet Finishes like 'brushed nickel' and 'stainless' vary between brands and look mismatched side by side.
Garbage disposal present
A disposal side uses the disposal's own mounting flange, not a basket strainer Basket strainers and disposal flanges are not interchangeable.

Brands that matter

  • Kohler: Wide range of strainers and dispensers in finishes that match its faucets.
  • Moen: Accessories matched to its faucet finishes.
  • Oatey: Plumbing basics: putty, strainers, traps and tailpieces.
  • Keeney: Common for drain parts, traps and repair kits.
  • Danco: Repair and replacement parts for existing fixtures.

What to avoid

  • Bathroom-sized (1-1/4 inch) drain parts for a kitchen sink
  • Flexible corrugated drain pipe in place of a rigid P-trap
