An old wash stand makes a classy addition to any home, but it can sometimes be impractical. To get the most from your wash stand, you can add a sink with plumbing lines to it. It is an involved process, but anyone can add a sink to their wash stand with the correct tools and a little patience. You will handle some dangerous power tools while you work, so always tie your hair back if it hangs lower than your shoulders and protect your eyes with goggles.
Examine the water pipes in the area where you will install the stand. If your water connection pipes come from the floor, you need to make room for them to come through the bottom of the wash stand. If the pipes protrude from the wall, plan to make access holes for them in the back of the wash stand.
Pull out all the drawers located directly below the wash stand's top. Open the doors at the bottom of the washstand so the bottom section is completely open.
Drill a 4-inch wide hole into the back or bottom of your wash stand, depending on the location of the water hookup pipes. Use a flat head wood drill to achieve the best results.
Measure the circumference of the sink bowl under the lips on its sides. Draw an outline on the top of the washstand that is the exact size and shape of the sink bowl.
Drill a pilot hole near the edge of the outline. Insert the blade of a jigsaw into the hole and cut out the outline.
Sand down the cut sections of the washstand with 60-grit sandpaper. Only sand the parts of the stand you cut or you might damage the finish. Clean away the debris and splinters using tack cloth (a sticky cloth designed for cleaning debris).
Place your faucet components onto your sink before you set it onto the stand. Tighten the bolt on the underside of the faucet components to hold them securely in place.
Line the bottom lip of the faucet with silicone caulk. Attach the flexible water lines to the faucet. Thread the loose ends of the flexible lines through the faucet holes in the top of the wash stand.
Push the wash stand up against the water supply lines.
Push the drain assembly through the bottom of the sink bowl so the top half protrudes past the sink drain hole. Place a line of caulk around the drain opening on the inside of the sink bowl. Set the drain ring over the hole (you may have to screw it into place) and clean away excess caulk.
Rotate the clips on the bottom of the sink so they face inward. Press the sink assembly to the wash stand so the end of the drain assembly meets with the drain protruding from your wall. Wipe away any caulk that leaks from under the sides of the sink bowl.
Crawl under the top of the wash stand and attach the loose ends of the water supply lines to the house's water supply lines. Tighten down the locknut on the end of the drain assembly to create a watertight seal. Flip the clips on the bottom of the sink so they rest under the top of the washstand, securing the sink in place.
Detach the bottoms and the back panels of the wash stand drawers. Slide them back into place and have an assistant hold them steady. Hammer finishing nails through the sides of the wash stand and into the sides of the draws, locking them in place.
