Prepare for the New Kitchen Sink Before you begin this project, read the manufacturer’s instructions and follow all local building codes. If you’re not comfortable installing a kitchen sink or related components (faucets and garbage disposers), Lowe’s can do it for you. Select the appropriate type of replacement sink. Single- and double-bowl drop-in sinks can be installed into most countertop surfaces. Undermount sinks install beneath the counter and should only be used with solid-surface and natural or engineered stone countertops. These instructions are for installing a drop-in sink. Step 1 Measure your existing sink. If your new sink has different dimensions and drain location(s) than the unit it will replace, you may need to modify the countertop opening and / or plumbing. Good to KnowFor best results, make a drawing of your old sink with all measurements including distances from the sink wall to the drain center to use as a shopping aid and reference. Or you can remove your old sink, take it to Lowe’s, and ask a Lowe’s associate to help you select a replacement unit. CautionWear safety glasses when working under the sink or cutting pipe and other materials. Step 2 Decide if you will also replace the faucet or install additional components such as a sprayer, soap dispenser, on-demand hot water tap or filtered water tap.Standard sinks have 1, 2, 3 or 4 holes on the rear lip for a faucet and additional components.Installation of a new faucet and other components is easier if it is done when you are installing a new sink, since you can easily access the hardware with the sink out of the countertop.

Step Two // How to Install a Kitchen Sink Lay out Sink Location Photo by Keller & Keller Mark the counter’s back edge to center the sink within its cabinet. If sink has a template, align it with the mark on the counter. Place its back edge 1½ inches from and parallel to the counter. Trace around it; proceed to the next step. If there’s no template, use 2-inch tape to outline the sink location. Mark the center of the sink on its back lip. Lay the sink upside down on the counter. Align the mark on the sink with the one on the counter. Adjust the sink to leave 1½ inches between its back edge and the backsplash. Be sure sink is parallel with the counter’s edge. Trace around the sink, then remove it. Measure the width of the sink lip, subtract 1/8 inch, and mark inside the sink outline by that much. To make the cut-out lines, connect all the marks with a straightedge.

Remove the Old Sink Before you begin, snap a picture of your plumbing configuration. This serves as a handy reference if you’re having trouble reassembling the plumbing later. Step 1 Turn off both the hot and cold water supply lines. The shutoff valves typically are in the cabinet below the sink or in the basement. If you cannot find them, turn off the main water line to the house. Step 2 Turn on the faucet to relieve water pressure in the lines. Step 3 Use adjustable wrenches to disconnect the water supply lines to the faucet. Have a small bucket ready to catch any water left in the supply lines and drainpipes as they are removed. Good to KnowLeave the faucet attached to the sink. You can remove both the sink and the faucet as one unit. Step 4 If you have a garbage disposer, turn off the circuit, then unplug it. Use pliers to disconnect the drainpipe and P-trap from the sink drain. Keep a bucket or pan underneath the drain to catch excess water. Step 5 Then remove the dishwasher drain line. Step 6 Remove the disposer following the manufacturer’s instructions. If you don’t have your disposer instructions, check the manufacturer’s website. Have a bucket ready to catch any water. Most disposers loosen at the mounting bracket connection to the sink drain and twist off. Step 7 Locate the metal clips under the counter around the sink’s perimeter. Loosen them with a screwdriver, open-end wrench or socket wrench and swing them toward the sink bowl. Step 8 Cut the caulk around the sink with a utility knife. Step 9 Push the unit from underneath and lift the old sink away. Step 10 Use a putty knife to remove grime, caulk and old plumber’s putty from the countertop. Likewise, clean any components you will re-install.

Depending on design, a kitchen sink may take up the entire top surface of a cabinet, or may be recessed into the countertop. To install a recessed sink, you need to cut a hole in the countertop to accommodate it. Some manufacturers will supply a cutting template with the sink. If not, you can draw your own guidelines. It is advisable to install the faucets and waste to the sink or countertop before the sink is secured in place because access is much easier. The method for connecting faucets is similar to that for a bathroom sink. In this example, a stainless steel sink is being installed into a laminate countertop.

4. Prepare the new sink by installing the faucet according to the manufacturer’s directions. Two common sink installation mistakes are, one, forgetting to clean the new sink thoroughly before installing and, two, forgetting to install the new faucet before installing the new sink. Factory-fresh stainless steel sinks smell awful, so it’s best to scrub them down outdoors. And it’s a lot easier to install the faucet before you install the sink, for at this stage, the mounting nuts are more accessible. While you’re at it, install all accessories too, including sprayer and detergent dispenser mounts.

Install The Disposal and Strainer Aaron Stickley Before installing any drain pipes, it is necessary to install the garbage disposal and basket strainer. Install the garbage disposal onto the desired side of the sink first, since this takes up the most space. On the other side of the sink (for two basin sinks) install a basket strainer. This is also a good time to install any other under-sink components such as a water filter or a ​hot water dispenser. Continue to 5 of 6 below.

Step One // How to Install a Kitchen Sink Sink Overview Illustration by Gregory Nemec The trickiest part of installing a new sink and faucet is connecting the sink’s drain—the pieces between the sink’s tailpiece and the waste line. Always start at the sink tailpiece and work down. This is where a swivel P-trap with a trap adapter earns its keep. It can swing side to side on two different axes and adjust up or down. Before you head off to the store, Richard recommends drawing a “map” like the illustration here and checking the inside dismeters of the tailpiece and waste line, usually 1 ½ inches. Then, instead of buying a kit, get only the pieces you need, including Schedule 40 PVC pipe to cut and fit as needed. Click “enlarge this image” to view illustration labels.
