Proper intallation of pedestal sink, are water supply lines supposed
to be visable behind a pedestal sink?

Dear monaseeta-ga; 

Thank you for allowing me to answer your interesting question. No, the
plumbing (ie the water lines) are not typically visible behind the
sink, rather they are INSIDE it. I think you?ll find this step-by-step
installation guide from Lowe?s quite helpful:

?Pedestal sinks come in two pieces?the stand (pedestal) and the sink
itself. The plumbing fits inside the pedestal, which is secured to the
floor.?

Having looked at a couple of sites on the subject, I believe that
those advertising their products are showing the ideal situation:  no
connections visible, but for the simple reason that there are no water
lines to the items shown.

Sites about installation reveal that the connection from the outlets
in the wall is visible.

From the practical side, if the outlets for the sink are in the wall,
the connection must be visible to some extent since the turn-off
valves have to be accessable.
