Today, we will show you how to install a flushmount sink. A flush mount sink installation, is where the flushmount sink is at the same level of the slab on which it is fitted. This is different from an undermount sink. To avoid any kind of slipping, or getting hurt from rough or hard edges, we recommend using protective gloves from either cloth or rubber.
Place the flushmount sink on the slab on which it will be fitted. Turn it upside down and mark the area to be cut on the slab. On the edge of the slab from, where we will use the sink, take a marking pen that contrasts in color, and mark a point at about two to four inches as per your preference.
This will be the gap between you and the flushmount sink. Make these markings at least at three positions along the same edge. Draw a straight line connecting these marks. Align the sink edge with this line. Now mark the outer periphery on the three remaining sides. Please take care and ensure that the sink doesn’t shift from its position. Otherwise the markings will deviate.
Remove the sink, and you can see the outer marked boundary. Inside this outer boundary, mark a distance of 10 mm on all four sides. Connect each new point with a straight line and you will get another rectangle inside the earlier one you made.
Cut straight through the inner boundary and all hollow out to the full depth of the slab on all the four sides. This is the cavity for inserting your sink. Now on the marked outer boundary, make a cut that is 10 mm wide and 6 mm deep.
This is how the l-shaped cut will look like once the cavity and the shoulder of the slab are ready. Take the sink and fit the faucets, hand shower, soap dispenser and couplings with the sink upside down. Use a black sealing tape and apply on the outermost edge.
The adhesive on the tape will stick nicely to the stainless steel sink. After fixing it on all four sides, overturn the sink, lower it into the cavity and ensure that the sink rests properly on the six mm deep cut shoulder of the slab. Get under the sink, use a holding clamp and place it in the under slot of the sink. Tighten it on the slab to the extent that the upper edges of the sink are level or flush with the slab .Put a few more clamps all around the flushmount sink.
Your sink is now well balanced and securely fastened from below. Place the supplied masking tape on the sink, on all four sides exactly from the outermost edge. Fill silicon between the sink and the slab and dab it gently. This will fill any vacant space. Clear any extra silicon. the masking tape will protect the upper edges of the sink from the drying silicon. When silicon is dry, remove the masking tape and then the green colored protective covering.
Your sink is now ready to use. We highly recommend installing the drain pipes before you lower the sink in the cavity.
