I just finished dry fitting our his/her sink plumbing in the master bath. A friend "apprentice" plumber chimed in to say it is no good. I know S-Traps are no-no's but properly vented may pass inspection??? The vent also picks up the shower and tub under the floor.

Am I good to glue or not? Thanks in advance for the expertise.

That is totally wrong.

The vent for the lavs will come off above the trap arm, not below.
The revent is at 42" above the floor. You can't run a dry vent below the flood level of the fixtures being served.
The trap goes into a vertical santee, with the vent out the top, reventing at 42" above the floor.

Now I need to rest my eyes. It hurt looking at that. :)

There is NO WAY to 'properly vent" an "S" trap, which is why they are forbidden.
