So, come on boys. Quit complaining and fit pedestals. That's what people hire you for! If it was easy then they would DIT!
Ian,
The trouble that plumbers have, is what to quote "before" you do the job on a pedestal.
Most of the time, it takes longer than the guess.
And then sometimes, they break during installation.
So really, it's the time, plus the insurance for incidental breakage, time to run to hardware stores to pick up different bolts to install with, and then finding out that the drain connection was never set up for a pedestal installation.
The bolts that come with pedestals, I just throw out immediately.
I pick up coach screws and anchors.
The wood screw end goes in the wall, hopefully into wood, if there is no wood, the wall anchors help.
The machine threads are for the lav side with big fender washers.
That way I can set the lav to the wall, throw on the fender washers, and thread on the nuts by hand. They are just to hold the bowl to the wall.
A base cabinet hides a multitude of plumbing sins.
The drain and supplies can be most anywhere, and still work.
With the door closed, it looks neat and tidy in the room.
A pedestal rough-in, needs to be planed before the drywall is ever put on, and even better before the framing.
