Zero reveals sinks look professional and there is no extra space for garbage and food to slip into. Most of the people go with zero reveal. And the last one is negative reveal, though it hides the rim of the sink under the countertop, the edges become dirty and hard to clean.

Trace the countertop of the quartz by placing the sink. Then trace the framework of the opening on the countertop. This is suitable for regular shapes like oval, rectangular or square. Use the instruction from the template given. It may be a paper template included with the sink or template printed on the cardboard carton holding it. Make your design by overturning the sink on cardboard; trace the outline of the sink mouth; and cut out the cardboard.

However, you will need to reduce the size of your template to cater to the rim that overhangs the basin. Form a length of plumbers putty and wrap the putty around the underside of the overhang on the sink strainer. Drop the strainer into the hole and exert pressure on the strainer to compress the plumber putty against the drain opening. Use the metal washer and rubber gasket that came with the drain to slip them onto the threaded end that extends below the sink.

Endeavor to clean the countertop with a solvent like alcohol before gluing them as directed by the manufacturer. Let it be parallel to the front of the counter.

Also, pour an unbroken bead of silicone caulk along the top rim of the rim. Ask an assistant to hold the sink against the underside of the counter the time you insert the end of a bar clamp through each of the drains of the sinkholes.

Tighten the clamp to hold the sink while still cranking the end of the clamp against the plank. Keep in mind that hard counters, like marble, quartz, and granite, often work better for this project than laminate or tile countertops. Figure out where you want to install the sink. The location depends on a few factors, such as the location of the water supply lines in your home.

Most sinks sit in the middle of countertops, but some installers choose a different aesthetic. Stone and concrete countertops work best with undermount sinks.

Wood, laminate, and other types of countertops tend to crack during the installation. Select a reveal style for your sink. This is important for appearance, but also has some effects on cleaning.

The rim will get dirty, similar to a regular drop-in sink. The overhanging countertop edges tend to get dirty and are hard to clean. Flip the sink over and trace around it with a pencil.

Then, remove the sink and measure the width of the rim. Simply put the template over the countertop, then trace it to size the opening correctly.

Put on safety gear, such as a dust mask and goggles. Then, choose the right saw for the material you wish to cut. For a material such as laminate, choose a jigsaw with a special laminate-cutting blade.

Not everyone has the tools needed. These countertops are also expensive, so damaged surfaces are not fun to contend with. Be sure to give your countertop fabricator the exact measurements of your new sink so they can cut it with precision. To make holes for the accessories like the faucet, use a drill. Choose a drill suitable for the countertop, such as a masonry bit for stone and concrete. Clean up the countertop and sink with denatured alcohol. Remove old caulk, sawdust or other debris on the countertop.

Use a scraper to eliminate any dried-out adhesive around the opening. Scrub it with a rag dampened in denatured alcohol to remove leftover debris. Unscrew the brackets under the sink by turning the wingnuts counterclockwise. Remember to shut off the water lines and detach the plumbing before attempting to lift the sink out. Method 2. Stack boards underneath the countertop to hold up the sink.

Many undermount sinks need to be lifted into position underneath a countertop. Center the sink in the middle of the hole in the countertop. Adjust the sink and the wood supports as needed. Align the rim of the sink with the cut edges of the countertop if you're going for a zero reveal aesthetic. Look down from above to make sure the sink is exactly where you want it.

Make sure it is even on all sides. Clamp the sink to supports to hold it in place while you install it. Set a piece of wood underneath the sink, then set another piece over the hole in the countertop. Pull the drain stopper out of the sink and lower the adjustable clamp through the drain.

Clamp the boards so the sink stays suspended about 1 in 2. Run a clamp through each drain. Another way to do this is with an undermount sink harness. The harness clips to the sides of the countertop. You then tighten the harness to lift the sink into place. Glue the studs to the underside of the counter with an epoxy paste. Get some undermount sink clips along with a bottle each of epoxy resin and hardener. Mix equal amounts of the resin and hardener together with a wooden stirring stick.

To install the studs, hold them to the countertop and spread glue over them with the stirring stick. Keep them no more than 10 in 25 cm apart. Spread silicone caulk around the countertop. Cut the tip off a canister of caulk and set it in a caulk gun. The bead of caulk needs to be above the rim of the sink. Choose a canister of a waterproof silicone caulk from a hardware store. This kind of adhesive holds undermount sinks in place long-term.

Tighten the clamps to bring the sink up to the countertop. Tightening the clamps raises the sink so it presses against the caulk. Adjust it before the caulk solidifies. Once the caulk solidifies, moving the sink becomes much more difficult. Install the sink clips and wingnuts over the glued studs. Fit a clip over a stud, then tighten it in place with a wingnut. Twist the wingnuts clockwise to tighten them. When the sink clips are installed correctly, they secure the sink tightly to the countertop.

If you notice a gap, the clips may not be on tight enough.
