Things You'll Need:
- Pencil Tape measure Crescent wrench Drill Safety glasses Level Lag bolts and washers 2 by 4 or 2 by 6 lumber Water supply lines Bathroom sink drain pipes P-trap
-
Step 1
Install an anchoring plate in the studs where the sink will be installed before covering the studs with drywall and finishing the drywall. Cut 2 by 4 or 2 by 6 lumber to fit in between the wall studs and either nail or screw them into place. Install the drywall and finish normally.
If the bathroom is already finished, plan on using drywall anchors to anchor the sink to the wall. -
Step 2
Place rubber bumpers on the bottom of the sink where the sink and the pedestal will meet to reduce the effects of shock and friction between the two components. Install the faucet onto the sink according to manufacturer specifications.
-
Step 3
Gently place the sink on to of the pedestal and position the sink and pedestal against the wall where it is to be installed. Be sure the sink is level. Mark the wall where the anchors need to be pre-drilled, and mark the floor where the pedestal anchor will be installed.
-
Step 4
Pre-drill the holes for the anchors in the floor and the wall.
Put the sink and the pedestal back into place where the anchor holes were pre-drilled, and add the anchors to the holes. Tighten the anchors to the wall and the floor, but do not over-tighten the anchors or the porcelain will crack. -
Step 5
Attach the water supply lines to the water shut-off valves coming out of the wall, and then attach the supply lines to the hot and cold sides of the water faucet installed in the sink. Tighten the fittings with a crescent wrench.
Run the drain pipes, installing the p-trap in between the drain pipe exiting the sink and the drain pipe entering the wall. Cut the drain pipes to fit as needed. Tighten the drain pipes by hand. -
Step 6
Slowly turn the shut-off valves on. Turn the faucet in the sink on and allow the water to flow for a minute. Check all of the water connections for leaks.
