Answer:
Assuming you can not move the plumbing or don't want to, hopefully the drain is centered and far enough back to be behind the pedestal. The supply lines probably are not. If possible, I would extend them straight up to the level of the bowl and then angle them to behind the pedestal. Paint them white, chrome, or some contrasting color depending on your color scheme. My take on things like this is if you can't hide it, call attention to it. Old original pedestal sinks often had brass tubes for supply lines that were made just for this and no one thought anything about them. It was just normal.
