Question HELP converting two independently switched lights to a 3-way

The master suite has a walk through shower area that has two independent lights:
  • LIGHT1 is controlled from SWITCH1 outside DOOR1 on one side of the room
  • LIGHT2 is controlled with SWITCH2 outside DOOR2 on the other side of the room

This is a really annoying configuration, so I would like to convert this to 3-way circuit so that BOTH lights can be controlled from a switch outside EITHER door. Is the diagram attached the best way to accomplish this (grounds removed for diagram simplicity)?

Basically, the plan is to:
  • Run new wire (probably two 14/2 wires) between the two switch boxes to facilitate the 3-way switching and marking accordingly
  • Replace each regular switch with a 3-way switch
  • Abandon the line feed originally supplying one of the switches (wire nut off in the box)

Please let me know if I missed anything. Thank you!

Welcome to the forums.

Yes....your diagram is correct and workable but it means you'll need 14-4 w/gr NM-b cable. That can sometimes be difficult to find. If you can't find it you'd need a 14-3 and a 14-2. You'd only need to use the black of the 14-2. You could cap the white off at both ends.
