How to Install a Stainless Steel Sink

Undermount sinks require a finished, water-resistant edge on the countertop.

Stainless steel is one of the most enduring trends in home decor. From refrigerators and dishwashers to ranges and custom hood vents, just about any appliance and fixture is available in stainless steel—including, of course, sinks. Stainless steel sinks can be installed on top or of below the countertop, depending on the countertop material. The fastening system used varies by model and manufacturer, so be sure to follow the manufacturer's instructions for your specific product.

Things You'll Need

• Stainless steel sink
• Faucet
• Jigsaw
• Drill and hole saw
• Drain parts
• Silicone caulk
• Caulk gun

1. Determine the best type of installation for your needs. There are two basic ways to install a stainless steel sink—undermount and top-mount. An undermount sink installs so that the finished countertop is installed over the lip of the sink. The main advantage is that when wiping debris and liquids off of the countertop, nothing gets caught at the lip of the sink. This installation is primarily used under granite and composite (solid-surface) countertops, although it can also be used with tile countertops with the proper detailing. A top-mount sink installs so that the lip of the sink rests on top of the finished countertop. The main advantage here is that the countertop does not have to be specially fabricated or installed so as to have a finished edge around the rim of the sink. Top-mount is commonly used with laminate and custom tile countertops but also works for stone and composite materials.

2. Install the rough top in preparation for an undermount sink, or install the finished countertop in preparation for a top-mount sink. The steps for installing undermount and top-mount sinks are basically the same. The major difference is that for an undermount sink (in most cases), the sink is resting on a plywood rough top, on top of which the finished countertop will be installed. With some countertops, there is no rough top, and the sink is attached directly to the underside of the countertop. This typically involves special anchors and adhesives and is best left to the countertop professional who is doing the installation.

3. Lay out the sink template on the rough top or countertop at the desired sink location. Most manufacturers provide a preprinted template with their sinks. Trace along the template to mark the cutting hole for the sink. Then, freehand another line approximately 1/4" inside the traced line (or as directed by the sink manufacturer). This is the line you will actually cut along, to provide a lip for the sink to rest on.

4. Mark holes for the faucet, as applicable. Another consideration prior to installing the sink is whether or not the sink has holes on the rear rim for the faucet. If the sink is manufactured without the faucet holes, the faucet will need to be mounted into the countertop. This typically requires a 1 3/8" hole saw of the appropriate type for the countertop material. Make sure the sink cutout allows sufficient room for the faucet.

5. Cut out the sink hole using a jigsaw or other type of saw appropriate for the material. Drill the faucet holes, as applicable.

6. Install the faucet into the countertop or onto the sink, as directed by the faucet manufacturer.

7. Apply silicone caulk along the rim of the sink, and fit the sink into or under the hole in the countertop. Secure the sink using the appropriate hardware. Carefully wipe away any excess caulk for a clean look.

8. Complete the installation by making the drain and water-supply connections below the sink.

Tips & Warnings

• Install your faucet and drain fittings into the sink prior to installing the sink into the countertop. This is much easier than crawling under the sink to do these operations later.

• Remember to measure twice, cut once! Remember the rookie who cut the hole three times and it was still too big!!!!
