How To Drill Holes for a Pedestal Sink

A pedestal sink, at its barest, looks like a basin sitting on a pedestal. Compared to countertop sinks and other bathroom vanities, a pedestal sink takes up less floor and wall area. Despite its slim look, a pedestal sink can still remain elegant and classy even if it is installed in a very small bathroom. This article describes the general procedure for drilling holes for a pedestal sink, as well as installing a pedestal sink.

  1. Prepare the installation area and materials. Remove the old pedestal sink and other old fixtures. Make sure water supply to the sink is turned off. Wear protective eyewear or goggles.
  2. Position the pedestal sink and its base. Unless you will be installing the pedestal sink in a location different from your old pedestal sink’s, you will most likely situate your new unit in the same location as the old one. Depending also on the model of your new unit, the base may not need to touch the wall, although it needs to be attached to the floor.
  3. Mark the mounting hole points. Making sure that the base and the sink are level, use a pencil, colored chalk, or marker to mark the mounting holes both for the sink and the base. If your new pedestal sink unit came with a template from the manufacturer, this should become easier for you. Just use the template to mark the drill holes on the wall and floor.
  4. Fire up your drill. Drill all the holes needed on both the floor and wall. Use the marked points as your guide. Use a masonry bit to drill the holes through the tiles and concrete.
  5. Secure the mounting bracket. To anchor the bracket securely onto the wall and floor, fasten the screws and ensure that the bracket is level.
  6. Install the faucet to the sink or basin. You will need to connect supply lines (usually flexible tubes) to the faucet. Make sure that you tighten the fittings so that the tubes won’t easily come off. Mount the faucet to the appropriate hole on the sink or basin and secure the faucet with putty.
  7. Attach or hook the sink to the wall bracket. Then, connect the drain assembly, making sure that fittings are tightly fastened.
  8. Install the base or pedestal. It will be underneath the sink. In most cases, you will secure the pedestal to the floor with bolts. Don’t fasten the bolts too tightly, though, as you could break the tiles or the base. Once the pedestal is securely in place, connect the faucet pipes to the water supply. Also connect the drain tube to the drainage pipe.
  9. Turn on the main water supply. Turn on the faucet on your sink and check for leakage, especially in the underside area and at the connection points of the supply tubes. Check also for leaks in the drain assembly. Fix all leaks before putting your new sink to actual use.

The process described in this article is something that you can do on your own. If you decide to do it yourself, you will be able to save some money and maybe learn some plumbing experience. However, if you can afford to do so, you may want to have your pedestal sink installed by a professional for a small fee. Many stores also provide free delivery of your sink unit to your home, as well as free installation of the unit.
