Remodeling bathrooms - plumbing layout

[Michael_0104298021]

Hey guys. I'm remodeling 2 back to back bathrooms sharing one common drain / vent. A friend suggested I post the layout up here to make sure I'm on the right track. Any thoughts / suggestions would be extremely helpful!

Looks pretty good. The stack is just a vent above the take off for the bathrooms right?
The revent from below ties in at 42" above the floor, six inches above the highest flood level assuming you have 36" high lav counters.
I would keep the venting 2" back to the main stack.

Hi Terry, thanks for the quick reply. Yes, from the floor plane and up, the stack is only a vent. I will definitely stick with the 2" vent back to the stack. Is there any other arrangement that would be more optimal, or is this layout how it would normally be done?
