Installing A Counter Top Bathroom Sink

If it is time for you to replace your old bathroom sink, you have several options. There are wall-mounted sinks, pedestal sinks, and last but not least, counter top sinks. We are working on the assumption that the counter top sink is what has been chosen. There are a wide array of beautiful counter top sinks to choose from. The installation process is relatively easy as long as you have the right tools and right attitude.

Begin by using the manufacturer provided template to draw the cutout line on the chosen countertop. If a template is not provided then use the bowl by turning it upside down and tracing the outline, then retrace a new line 3/4″ inside that one to use as your new cut line. Drill a 3/8-inch starter hole inside the cut line for the saber saw to make the initial cut, then follow through. Try screwing a scrap board, longer then the span of the cutout, to the center of the cutout to prevent it from falling when you finish cutting. Be sure to remove the support after you finish.

Now, place a bead of plumber’s putty around the base edge of the drain-assembly housing lip, then put pressure on the housing, pushing it into the drain hole. You then attach gasket and washer and tighten the locknut. Be sure to remove and clean-up any excess putty, then attach the tailpiece to the housing using the slip nut and washer. If the sink has a pop-up assembly, remove it before installing the faucet. Now you will want to install the faucet into the sink-body. When it is in place, turn it the sink upside down and run a bead of silicone adhesive along the underside of the sink’s lip/edge. Lower the sink into the counter top and align with the front edge while pressing firmly around the lip. This will provide a tight seal after the adhesive sets. Once it is set, apply a bead of latex caulk around the sink’s edge for added protection, smooth down with the tip of a wet finger.

Install the pop-up assembly now. Remove the stopper from the tailpiece, then install the tailpiece as shown so the pop-up port faces the spout. Attach the pop-up to the tailpiece, and thread the pivot rod into the opening at the drain stopper. Put the lift rod in the spout, attach to the pivot rod by the extension rod, and adjust so the drain stopper will open and close properly when the rod is operated.

Now you will want to connect the faucet’s hot and cold supply lines, bend them gently so they attach, and meet, the shutoff valves. Be sure the compression nuts and flared fittings are tightened appropriately. Ensure that the lines are clear and free of any debris while also checking for leaks.

That is all there is to it. Remember the best time to install a counter top sink is after you have removed a wall mounted or counter top sink, so the wall and/or floor underneath the removed sink will not need to be altered. Now you are ready to enjoy your beautiful new counter top sink.
