Master bath single vanity to double vanity drain plumbing

[Andj]

In process of redoing my master bathroom. Will be changing single vanity to double vanity.

Current stack is in far left of wall where vanity sits. Current single vanity has a 2" horizontal ABS wet vent to 3" abs stack. Toilet is also connected to same stack. This is on second floor with no additional items utilizing the drain stack from above.

Was wondering on what the best recommended way to convert drain plumbing to support double vanity. Came up with the following idea. See Image. Is this the best way to go?

In Toronto Canada if it matters.

In most cases, doing that would position the outlets too high to connect to the sinks.

You normally run 2" before you split to two.
