Now that you've decided to rejuvenate your bathroom with a pedestal sink, let's bring your vision to fruition. There are only two parts to this sink (the basin and the pedestal), and the project takes some measuring, a few bolts and some caulking (not to mention some muscle and an extra set of hands). However, for their stylish attributes, pedestal sinks present their own installation challenges. They can be quite heavy and cumbersome, but don't let the weight of these parts intimidate you. This job is really nothing more than a series of small steps.
Tools and materials you'll need
The main challenge in this installation is not so much in the amount of tools needed, just in being steady and meticulous in your measuring, as well as having that extra set of hands so your brand new sink doesn't come crashing down.
Remember! Get the right tools for the job:
Before you begin
Before you do anything, cut the water supply and drain the hot and cold lines into a bowl or bucket. Next, rough in a new waste pipe, something you may want to hire a plumber to do.While you have the wall open, install blocking. Consider a horizontal 2x4 screwed between the studs at basin height, beneath the plaster or drywall. Blocking provides a solid anchor for the lag screws and will hold the sink securely against the wall.
Mark the location
Freely set the basin and pedestal in position and prop up the basin with 2x4s. This may be a good time to get that extra set of hands. Either way, just make sure the sink is steady. With the sink level, mark the location for the mounting holes on the wall for the basin and pedestal.
Make your connections
Attach the new faucets and drain assembly onto the basin. Don't make it too tight, though, or the sink could crack. Apply a bead of plumber's putty (or Teflon tape) at the bottom of the valve handles and faucet for a watertight seal. These adhesives are the best way to ensure that your newly installed drain won't leak. It's also a good idea to run the water to test for leaks.
Get attached, get very attached
Attach the drain pipe to the basin's drain basket, and fasten the water supply lines to the new faucets. Connect the supply lines to the mixer.
In with the new
Set the new sink into place and use it as a template to determine where the lag screws are placed. Pre-drill holes for these screws, then use the nuts to screw them into the wall. Be sure to bolt only the basin in place, and be careful once again not to over-tighten the bolts and crack the sink.
With the basin supported by 2x4s, slip the pedestal out from under the basin. Connect the P-trap, and attach the water supply lines to the faucet. Once again, apply plumber's putty or Teflon tape and turn on the water to check for leaks.Scoot the pedestal back into its final position under the basin and bolt it to the floor. If it's not designed to take on floor bolts, simply apply adhesive caulk to the bottom and top of the pedestal before putting it in position.
Finish the project by applying adhesive caulk to the joint between the sink and the wall. Smooth and blend with your finger.
