Find my drain
Tool

Which sink drain do I need?

Answer four questions about your sink. The finder names the drain type, tells you what to check on the box, and builds two searches filtered for your finish.

Your drain

How the finder decides

  1. Sink type sets the drain family. Kitchen sinks take basket strainers. Bathroom sinks take pop-up drains. Vessel sinks take umbrella, push button or grid drains with a long body. Bar and prep sinks vary.
  2. Overflow sets the drain body. A bowl with an overflow needs a slotted body; a bowl without one needs a solid body (VIGO). If you are not sure, the finder shows how to check.
  3. Hole size checks the fit. Kitchen strainers fit a 3-1/2 inch hole, and some cover up to 4 inches (Houzer, Keeney). Bathroom drain holes vary (Hunker), so the finder tells you to match the range printed on the box.
  4. Finish only changes the search. It does not change what fits.

When the finder is not enough

Questions people ask

How do I tell if my sink has an overflow?

Look for a small hole or slot near the top of the bowl, usually at the front or back, below the rim. Bathroom sinks often have one; kitchen and vessel sinks often do not. If you see one, you need a drain body with overflow slots.

How do I measure the drain hole?

Take the old drain out, then measure straight across the hole in the sink from edge to edge. Do not measure the old flange on top: it is wider than the hole. The size guide has a tap-to-check tool.

Are the suggestions tested?

No. We have not tested these drains ourselves. The finder applies the fit rules from maker guides and plumbing references, then searches current listings for that drain type and finish.
