Step 2 · Precise Sink Height Marking & Measurement

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Measure and mark the desired sink height on the wall. The standard height is 31-34 inches from the finished floor to the sink's top rim. Always check the sink manufacturer's instructions for their specific recommendations. Double-check this height against your plumbing diagram to ensure enough clearance for plumbing connections beneath the sink. Careful measurement prevents costly mistakes later.
