Thanks guys, - - and yes, - - lots of angles that had to be charged accordingly for, - - definitely a very tricky job, - - the design worked much easier from above then below, - - all the utilities are located basically right below the sink and toilet of this new bathroom (heater, gas meter, water meter, sump pump, AC condensate lines, just to name a few), - - and the shower is located over a tight crawl space.
Yes, - - I did all the plumbing myself (and everthing else), - - the staircase runs behind and over the toilet, - - which made venting tough to figure, - - but luckily I was within the 5' rule, - - so I did a loop vent in the wall behind the pedestal sink, - - and tied that back in below to the old house vent.
As far as the supply lines to the pedestal sink, - - it's not by accident that they're hard too see, - - I installed them both to the right of the pedestal base, - - to try and hide them from view from the main room or upon entering the bathroom. I also painted the PVC drain arm a brighter white to better match the trimwork color, - - it's all in the details, right??
Here's a quick scan of the before and after on the design/location, - - sorry so quick and sloppy, but I'm on the run.
