When you pick out your pedestal, you should also pick out a bathroom faucet that is compatible with the faucet holes in the sink top. This is not a big challenge. You have two choices: A 4" centerset or 8" wide centerspread, meaning the distance center to center between the outside holes.
Here's a handy installation tip: Hook up the faucet, drain assembly, and drain plug lift rod to the sink before you mount the pedestal. Then attach the sink to the wall with the bolts provided. Be careful not to over-tighten, or you could crack the porcelain. Now attach the water supply lines and the drain assembly. Turn the water on and check for leaks.
