Installation Considerations

Installing a double sink vanity involves several steps. Here's a general guide to help you through the process:

1. Gather the Necessary Tools and Materials:

  • Double sink vanity
  • Measuring tape
  • Level
  • Screwdriver
  • Adjustable wrench
  • Pipe wrench
  • Hacksaw (if needed)
  • Plumber's putty
  • Silicone caulk
  • Water supply lines
  • Drain assemblies.
  • P trap(s)
  • Shutoff valves (if not already installed)

2. Measure and Mark the Placement: 

Measure the dimensions of the vanity and ensure it fits in the desired location. Use a level to ensure the vanity will be installed evenly.

3. Shut Off the Water Supply: 

Locate the shutoff valves under the sink or near the main water supply line. Turn them clockwise to shut off the water supply to the sink area.

4. Remove the Old Vanity (if Applicable): 

Disconnect the water supply lines and the drain pipes from the existing sink. Remove any caulk or adhesive securing the vanity to the wall. Carefully detach the vanity from the wall and remove it from the area.

5. Install the Faucet and Drain Assemblies: 

Follow the manufacturer's instructions to install the faucets and drain assemblies onto the sink(s) before placing them on the vanity.

6. Place the Vanity: 

Set the double sink vanity in its intended location, ensuring it is level. Mark the positions of the back and side walls on the vanity.

7. Make Necessary Adjustments: 

If the vanity doesn't fit flush against the wall due to baseboards or uneven surfaces, use a hacksaw or a jigsaw to modify the vanity or the wall.

8. Connect the Water Supply Lines:

Attach the flexible water supply lines from the shutoff valves to the faucet connections. Tighten the connections with an adjustable wrench.

Ensure the hot water supply line connects to the hot water faucet and the cold water supply line connects to the cold water faucet.

9. Install the Drain Pipes:

Attach the P-trap(s) to the sink drain(s) using the provided gaskets and slip nuts. Adjust the trap's height as needed to align with the drainpipe.

Connect the P-trap(s) to the wall drainpipe or the main drain line using the appropriate fittings. Ensure all connections are tight.

10. Secure the Vanity to the Wall: 

Use screws or brackets to secure the vanity to the wall at the marked positions. Ensure it is level before fully securing it in place.

12. Apply Plumber's Putty and Caulk: 

Apply a small amount of plumber's putty around the base of the faucet(s) and the drain flange(s) to create a watertight seal. Then, run a bead of silicone caulk along the edges of the sink where it meets the countertop and walls to prevent water from seeping underneath.

13. Reconnect the Water Supply: 

Turn on the shutoff valves to restore the water supply to the sink. Check for any leaks and make adjustments if necessary.

14. Test the Sink and Drains: 

Run water in both sinks and check for any leaks around the faucet connections and drain assemblies. Ensure the water flows properly through the drain pipes without any backups or obstructions.
