These instructions are for installing a self-rimming, drop-in bowl--the easiest type to put in.

If you're installing a self-rimming sink in a new countertop, you'll start by making a cutout for the bowl.

Nearly all sinks are sold with a template for marking this hole. Position the cutout according to the manufacturer's directions.

A single sink is typically centered from side to side and front to back.

When installing a heavy sink (such as cast iron), you can simply use a bead of plumber's putty rather than adhesive to seal the edges; the sink's weight will hold it in place. If you are installing a recessed or frame-mounted sink, attach the sink with the mounting clips or metal strip included with the unit.

	1. Use the sink manufacturer's template to draw the cutout line on the countertop. If no template is provided, set the bowl upside down on the countertop and trace the outline, then draw a second line about 3/4 inch inside that line to serve as your cut line.
	2. Carefully drill a 3/8-inch starter hole inside the cut line. Using a saber saw, begin cutting along the line. Before finishing the cut, screw a scrap board longer than the span of the cutout to the center of the cutout to prevent it from falling when you finish cutting. Remove the support after you finish the cut.
	3. Place a bead of plumber's putty around the bottom edge of the drain-assembly housing's lip, then press the housing into the drain hole. Attach the gasket and washer, then tighten the locknut (hold the handles of a pair of pliers in the housing with a screwdriver to prevent the housing from turning while you tighten the locknut). Remove any excess plumber's putty. Attach the tailpiece to the housing with the slip nut and washer.
	4. If you haven't already done so, install the faucet as discussed HERE. When the faucet is in place, turn the sink upside down and run a bead of silicone adhesive along the underside of the molded lip (adhesive is included with some sinks). Turn the sink over and carefully align it with the countertop's front edge. Press firmly around the lip to form a tight seal. After the adhesive has set, apply a bead of latex caulk around the edge, then smooth it with a wet finger. Install the pop-up assembly (see Installing a Faucet).
	5. Set the sink in place, firmly pressing down all edges to assure a secure seal.
