What Size Is a Standard Laundry Sink in Australia?

There isn't one standard size, but many laundry sinks are around 510mm to 600mm long and 450mm to 500mm wide. Small laundry sinks suit tight cabinets. Larger sinks and troughs give you more room for soaking, buckets, and bigger items.

The outside size of the sink is only part of the story. A 600mm-wide sink won't always fit a 600mm cabinet, because the internal opening is smaller once you allow for the cabinet sides.

Check the internal cabinet width, bench depth, bowl depth, and space for waste pipes underneath. Then use the product drawing to confirm the fit. We see this save a lot of trouble when you're replacing an existing sink.
