How to Install a Pedestal Sink

Installing a pedestal sink where one already exists is an easy job for almost any homeowner. Although slightly more intimidating than installing a vanity, installing a pedestal sink is still an task that is within the skill set of many do it yourselfers.

Start by removing the existing pedestal sink. To do this, you must remove the mounting screws that attach the basin to the wall as well as the actual pedestal that is normally attached to the floor with a bolt. You must also detach the water supply line and the drain lines from the sink using an adjustable wrench.

Now, with the old pedestal sink removed, place the new pedestal sink in it place, using a couple of 2″x4″ cut to size to help support it. Using a pencil, trace around the basin where it meets the wall as well as where the pedestal meets the floor. Also make marks where the holes in the unit are located for the mounting screws.

Remove the new pedestal sink and drill holes for the new mounting screws, making sure the hole s in the wall hit blocking or a stud. Fill in the old holes from the existing unit, especially if the old holes will be exposed. You may also want to paint or wallpaper the area as needed.

Now you can install the new pedestal sink, beginning with the pedestal. Use lag screws to anchor it to the floor, and place the basin on top of it. Attach the faucet to the basin and align the basin with the mounting holes. Attach the sink to wall using lag screws and washers, being sure not to over tighten and crack the sink.

Next you should reconnect the drain fittings and water supply using an adjustable wrench. Test the basin to make sure that the faucet and drain is working properly. Make any needed adjustments and address any leaks. When the unit is functioning to your satisfaction, use some silicone caulk to seal the connection between the basin and the wall.

Install a new pedestal sink where an existing one is already located is an easy job for homeowners with some knowledge of plumbing, but may be too difficult for a true beginner. Consider also, that if there is not already an existing pedestal sink in place, you may have to install blocking in the wall and rearrange plumbing to properly install one. In this case, consider calling a contractor to do the work unless you have significant experience.
