Materials Needed

  • Double vanity
  • P-trap
  • Drain
  • Plumbing wrench
  • Plumbing tape
  • PVC glue
  • PVC pipes
  • Water supply lines
  • Basin wrench
  • Pipe cutter

Step By Step Guide

Step 1: Prepare the Vanity

Before installing the double vanity, you need to prepare it for plumbing. Remove any drawers or shelves to give you access to the underside of the vanity. You will need to measure the distance between the drain and water supply lines and mark the vanity accordingly.

Step 2: Install the Drain and P-trap

Start by installing the P-trap onto the drain. Make sure to use plumbing tape on the threads to ensure a tight seal. Insert the drain into the drain hole on the vanity and tighten the nut underneath to secure it. Use a plumbing wrench to tighten the nut, but be careful not to overtighten and crack the drain.

Step 3: Install the Water Supply Lines

Attach the water supply lines to the valves underneath the sink. Use a basin wrench to tighten the nuts, but again, be careful not to overtighten and damage the valves. Make sure to use plumbing tape on the threads to ensure a tight seal.

Step 4: Connect the Drain and P-trap to the Plumbing

Using PVC pipes and PVC glue, connect the P-trap to the plumbing. Cut the PVC pipes to the appropriate length using a pipe cutter. Make sure to use PVC glue on each connection to ensure a tight seal.

Step 5: Test the Connections

Turn on the water supply and check for leaks. If there are no leaks, turn on the faucet and let the water run for a few minutes to ensure that the drain is working properly.
