Pedestal Sink Installation Made Easy

TOOLS AND MATERIALS REQUIRED: Level Drill with assorted bits 9/16″ wrench Tape measure Framing square Channel lock pliers

Some notes before you begin: 1) Observe all local plumbing and building codes. 2) Prior to installation, unpack the new lavatory and inspect it for damage. Return the lavatory to its protective carton until you are ready to install it. 3) These instructions are for installing the lavatory to wood frame construction. For other installations, supply suitable bracing and fastening devices of sufficient size and strength. 4) The walls and floor must be square, plumb, and level.

Pedestal Sink Installation Instructions

Step One: 1) Rough-in the supplies and drain piping Note: The supply stop handles cannot extend more than 3″ from the finish wall when in the open position. 2) Install sufficient backing behind the finish wall to provide a secure material for the anchoring devices. 3) Apply two self-adhesive gaskets (provided) to each of the three ridges in the bottom recess of the lavatory.

Tips to Remember: 1) Lavatory selection: When replacing a pedestal lavatory, keep in mind, beyond color and style, additional criteria in selecting the piece for your bathroom or powder room. 2) The unit may expose wall and floor imperfections, which may complicate the installation. 3) If you do not want anything touching the floor or an easier to clean system, try a shrouded lav, they are as sturdy as the pedestal lav and give a nice open look to the room.

Step Two: 1) Mark the centerline on the floor. 2) Position the pedestal on the floor centerline. 3) Carefully set the lavatory on the pedestal. 4) Move the pedestal as required to ensure proper fit in the desired location. 5) Level the lavatory. Add more self-adhesive gaskets as needed to level the lavatory. Note: The lavatory must be supported by the pedestal. 6) Check the lavatory placement. 7) Mark the center of each anchoring hole on the wall, and mark the floor through the hole in the pedestal bottom. 8) Carefully remove the lavatory from the pedestal. Then move the pedestal from the area.

Faucet selection: The faucet will require proper clearance between the stopper level and the wall.

Step Three: 1) Drill a ” mounting hole at the mark on the floor, then drill two ” hanger bolt holes at the marks on the wall. 2) Mount hanger bolts to the wall so approximately 1-1/4″ of each bolt remains exposed. Note: other fastening devices of sufficient size and strength may also be used. 3) Install the faucet and drain to the lavatory according to the manufacturer’s instructions. Note: Do not fully tighten slip-joint drain connections at this time.

Existing hardware: With pedestal sink lavatories, wall mounted, or shrouded lavatories, you will have a substantial amount of supply and drainage hardware exposed to sight. Make sure your P-trap, supply lines, and valves are acceptable for the appearance. This is a perfect time to change and upgrade.

Before installation: When you open the box(es), you will want to do a quick check to make sure all the parts are included. There will be a parts check list in your instruction booklet.

You will want to install the faucet and drain onto the lavatory top before you install the top. It is easier to work with at this point and the two pieces don’t add too much weight.

Step Four: 1) Position the pedestal mounting hole over the hole in the floor. 2) Secure the pedestal to the floor with the wood screw and washer. Tighten the wood screw until it is snug. Caution! Risk of product damage: Do not overtighten. Overtightening the wood screw may cause damage to the product.

Step Five: 1) Set the lavatory on the pedestal so the hanger bolts extend through the lavatory holes. 2) Level the lavatory. 3) Install the cap nuts and washers, and tighten until snug. Caution! Risk of product damage: Do not overtighten the cap nuts. Overtightening may cause damage to the product. 4) Connect and tighten the trap. Connect the hot and cold water supplies to the faucet.

Installation tips: If available, the installation is much easier with two people. Some of these lavatories are very heavy and can be cumbersome to move around. The most important time for help is when you are putting the lavatory onto the mounting hardware and lining up the P-trap at the same time. It is great to have someone lifting and placing while the other is lining up the pipes.

Installing the legs into the wall is a relatively simple job. However, when screwing in from the threaded side, put a threaded rod connector over the threads to protect them (another option is to use multiple nuts). This will make a much easier time of tightening the nuts while holding up the lav top.
