I'm replacing the bathroom vanity cabinet, sink and countertop, located between two walls. Picture below. I plan to cut the current p-trap arm, leaving enough of it sticking out of the cabinet to attach a coupling and connect to a new adjustable p-trap with slip joints.
what parts do I need? the piping is 1-1/4" ABS.
I presume a 1-1/4" to 1-1/4" coupling, a piece of 1-1/4" pipe, a 1-1/4 pivoting p-trap with slip joints. Will sink drain extension be needed, or goes directly into p-trap?
