How to Install a Pedestal Sink

Home Improvement

Give your bathroom style and more room with a pedestal sink. Before you start, check the installation instructions for support, and plumbing requirements. Keep in mind you might need to reroute plumbing. To remove your old vanity, turn off the water supply and turn on the faucet to relieve pressure in the lines. Loosen the nuts to remove the drain pipes, and disconnect the water lines from the valves. Cut the sealant along the backsplash and remove. If your vanity is secured to the wall, separate the top from the vanity with a putty knife, lift it off and back out the screws. The vanity should now pull out. With the old vanity out you can make plumbing repairs such as moving the supply lines and drain. Consider installing new plumbing since it will be visible. Some pedestal sinks require a support board behind the finished wall for extra strength. To install, mark the sink height on the wall, cut out part of the wallboard and studs, and install the support board with screws. Then repair the wall surface. This is an ideal time to paint, install wall tile or new flooring.

To install the new pedestal sink, mark the centerline on the wall and floor. Then make a mark 10 inches from the wall– accounting for the baseboard. Position the pedestal on the mark, and set the sink tight against the wall, check for level and adjust the pedestal as needed. Mark the sinks anchor holes on the wall and the pedestal hole on the floor. Move the sink and pedestal aside, and drill the three holes. Next, install hanger bolts in the wall leaving about 1 inch extending from the wall. Secure the pedestal to the floor with a lag bolt and washer. Dont over tighten. Attach your faucet and drain before setting the sink bowl in place. Now position it over the hanger bolts, level it, and secure it with cap nuts and washers.

Again, dont over tighten. Reconnect the drain and water supply, and check for leaks. Consider adding a new mirror and lighting fixture to match the look of your new sink.
