How to Install a Pedestal Sink

Connect the Tubes
With the fixtures in place, connect the plastic supply tubes to the Tee at the bottom of the spigot. Then connect the water supplies to the faucets. Leave the water supplies dangling. Use two wrenches working against each other to make a tight joint without stressing the piping.
Connecting a One-Piece Fixture
To connect a one-piece fixture, start here. Connect two supply tubes to the inlets, using two wrenches as already shown. Then mount the fixture to the sink with lock rings or lock nuts, tightening with a basin wrench. Then continue from here.
Connect the Tailpiece
The last sink connection is the tailpiece, which connects to the drain. Place a ring of plumber's putty around the flange that enters the sink from above, insert the tailpiece from above, and tighten the lock ring from the bottom.
At this point, you have connected the spigot, two faucets, and the tubes connecting these parts. And you haven't spent a second on your back!
Step 3: Mount the Sink
You knew it had to happen. At some point, you'd have to lift this sink!
Test-Mount the Sink
Position the pedestal and place the sink on it, flush to the wall. When the sink is level, mark the mounting holes.
Center and level the sink on the pedestal. Hidden shims adjust the angle. Mark the mounting holes at the bottom outside.
With the sink in place, measure and cut the drain parts to length. Kevin cut the drain tubing with a tubing cutter, a special-purpose gadget with a cutting wheel, but a hacksaw will also work.
Remove and Replace the Sink
Pull the sink away from the wall and drill holes for your fasteners. If there is framing behind the mounting holes, drill for two 5/16" × 3" lag screws. Otherwise, use spring toggles.
With the holes drilled, return the sink to the pedestal. Drive in the lag bolts or insert the spring toggles. After you push a toggle through the wall, its wings will expand and lock on to the wall. Pull the bolt toward you as you start tightening, so the wings grab the wall instead of whirling inside it.
Don't tighten either a lag bolt or a spring toggle with your Tarzan routine—you could break the sink!
Step 4: Finish Up
With the sink finally mounted, a few connections will complete the job.
To connect the drain pipes to the plastic drain pipe coming out of the wall, install an adapter. Goop the proper solvent onto the pipe, and then twist the fining into place.
Tighten the drain assembly with locking pliers or a pipe wrench. Tighten evenly, holding the parts in good alignment. Connect each water supply to the stop, the valve that shuts off the water from the house supply. An adjustable wrench will not scar metal like a pipe wrench.
Open the stops and test for leaks. Tighten any leaking pipes gently until you can't feel any water on your hand.
