Step 3 · Connecting the Bathroom Sink Plumbing

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

Position the sink and carefully connect the supply lines to the shut-off valves. Attach the P-trap to the drain and tailpiece, ensuring the drain pipe is positioned 18-20 inches above the floor. Remember to use sealant on all threaded connections to prevent leaks.
