This is a photo from when my home was built in 2014. As you can see it was plumbed for a single sink vanity. Like others here I am wanting to replumb the drain to accommodate a double vanity. What’s the easiest way to accomplish this. You can’t see it in the photo but there is 3-4 feet of wall past the single drain pictured which will allow me add the additional drain and vent im assuming. I know very little about plumbing. I figured out how to split the water supply (not pictured here). Thank you in advance!

This is what John's link is getting at. You will need a long sweep 90 coming off the waste. Code is to use a 2x1.5x1.5x1.5 but my supplier only had 2x2x1.5x1.5 so i used a reducer to vent to 1.5. Also, your vent has to be 6 inches above flood level (top of vanity) which is typically 42 inches. My vanity is 37 inches off the floor so i set my vent to over 43 inches off floor level.
