Installing a new stainless steel sink in your kitchen will make food preparation and cleanup amazingly easier. A double or single sink can be used for many purposes besides just washing vegetables and dishes. Follow the directions below to install a stainless steel sink into your kitchen countertop.
Step 1 - Connect the Faucet
Fit the faucet unit into the countertop and connect the taps to the hot and cold water pipes under the sink with a pipe wrench.
Step 2 - Cut the Countertop Hole to Fit the Sink Bowls
Measure the distance from the faucet to the countertop edge. Lay the cutting template for the countertop on the counter and outline it with a pencil, allowing a countertop edge of 2 inches at the front. Cut out the countertop hole for the sink, following the template outline. Gently sand around the upper edge of the countertop hole to remove splinters and rough laminate pieces.
Step 3 - Caulk the Sink Edge
Invert the sink unit over the countertop hole and apply a thick strip of silicone caulking all around the sink's lip edge. Press it down slightly with the putty knife to keep it in place when you flip the sink unit over. Use silicone caulking instead of plumber's putty as the putty tends to dry out after just a few years.
Step 4 - Press the Sink Unit Down into the Countertop
Turn the sink unit over and set it down into the countertop, pressing down heavily on the lip edge. A band of caulking should ooze out all the way around the sink edge, showing a tight, waterproof seal has been formed.
Step 5 - Fasten the Sink Edge to the Underside of the Countertop
Place four T-screw clamp fasteners at the four corners of the sink unit, with the slot head of the screw at the bottom. The clamp fastener grips the top and bottom of the countertop and the screw passes through the stainless steel of the sink itself. Tighten the screws a little at a time each with the flat-head screwdriver until the clamps bite solidly into the countertop at top and bottom. The sink lip should be level all the way around when the screws are tightened correctly.
Step 6 - Clean Off Excess Caulking with a Putty Knife
Wait at least two hours for the caulking to harden. Carefully scrape off the excess hardened caulk from around the sink edge with the putty knife and utility knife. If you try to clean off the caulking before it has set it will stick firmly to your tools, your hands, your clothes, and the countertop.
Step 7 - Test the Taps and Plugs for Leaks
Put the drain plugs into the sinks and run the hot and cold water taps to fill them 1/3 full. Check for faucet leaks and that the drain plugs hold firmly.
