Pedestal sinks are popular in small bathrooms where there isn't room for a vanity, and are available in multiple styles to match almost any decor. Although it may appear to be freestanding, a pedestal sink is anchored to the wall for security and can be installed on almost any type of flooring, including tile.

Instructions

  1. 1

    Carefully stand the sink pedestal in an upright position. Align the pedestal with the plumbing in the wall or floor. Set the basin on the pedestal; slide both basin and pedestal until the back of the basin is touching the wall. The pedestal will be several inches from the wall.

  2. 2

    Mark the basin anchor holes on the wall with a pencil. The anchor holes are located at the back of the basin and can be seen underneath the basin. Mark the location of the anchor holes in the pedestal base on the floor. Move the basin off of the pedestal, and set both basin and pedestal out of the way (Ref. 1).

  3. 3

    Drill the floor-anchor locations with the drill and the appropriate-size diamond carbide drill bit. The instructions should indicate what size of bit is needed. Drill slowly, and sprinkle water on the tile while drilling. This type of drill bit gets hot drilling through tile; water keeps the bit cool and the tile from cracking. Insert the provided anchors into anchor holes. Not all pedestal sink bases require floor anchors; it is based on the model that you purchase.

  4. 4

    Install the faucet and drain assembly on basin before setting pedestal and basin in place. Follow the manufacturer's instructions for installation of faucet and drain. Tighten everything by hand until pedestal and basin are secured in place. Connect the water lines to the shutoff valves if they are not already. You will finish the plumbing connections when the pedestal sink is firmly secured to the wall and floor (Ref. 2).

  5. 5

    Set the pedestal in place over the anchor holes. Place a level across the top of the pedestal, and use the provided shim cushion or a wood shim to adjust until level. The shims go between the pedestal base and the floor.

  6. 6

    Insert anchor bolts through pedestal base and into the anchors. Carefully tighten the bolts, but do not over tighten. Set basin on top of pedestal and anchor to the wall anchor plate with provided bolts.

  7. 7

    Caulk around pedestal base with the latex kitchen and bath caulking.

Tips and warnings

  • It is easier to reinstall the faucet parts and connect plumbing before the pedestal sink is set and anchored in place.
