Sink Trap size

TopTrumper · 17 Jan 2006

Just a quick one fellas.
Can somebody confirm the standard bathroom sink waste trap is 32mm?

ChrisR · 17 Jan 2006

Bathrooms don't have sinks, generally, they have basins.
Sink waste is usually 1 1/2"= 40mm
Basin Waste is usually 1 1/4" = 32mm
Those are pipe diameters

Traps have "seals" measured in steps like 50mm, 75mm.
