I just ripped out a bar for a customer that had a sink in it.  The bar was in the basement which I’m in the process of remodeling.  I’ll be making a new bar which won’t be a pennisula set up, but it will be along a wall (like a kitchen cabinet).  Dilema (aside from figuring out the new forum):  The old drain is approx. 30″ from a wall.  Old setup – 1 1/2″ copper drain line into drum trap then copper drain line into 4″ cast iron.  Since I can’t use an S-Trap, any suggestions for running a drain through the floor. 

I can send pictures if needed.

Thanks Dave
