Kitchen&BarSinks:Drop-In
Drop-in kitchen sinks are easy to install and are designed to install 
beautifully in a wide range of countertop surfaces. Sinkology Drop-In 
kitchen sinks make DIY kitchen renovations effortless and impactful. 
Drop-In sinks can be used to replace an old sink or installed in 
luxurious new countertops.
1.  Flip sink upside down and trace the outside edge onto craft 
paper or cardboard. Add a second line that is 1/2” inch inside 
that line. Cut out the traced template using the second line. 
2.  Positionthetemplateatonthecountertopandalignwith
cabinet and plumbing connections. 
3.  Mark openings and cut the countertop. 
4.  Alwaysdoublecheckthesinkfortinsidetheholebefore
moving on. 
5.  If your sink does not come with mounting hardware, refer to 
bath sink drop-in installation instructions on page 4. 
6.  Before dropping your new sink into the countertop for the last 
time apply a thick bead of Sinkology antique brown or clear 
neutral cure 100% silicone around the hole on the countertop 
to form a water tight seal around the sink. See our Complete 
SiliconeInstallationKit(#SINSTALL-101) for Copper Sinks. 
7.  Install hardware. Place 
notched end of all bolts 
into the keyhole slots. See 
diagram. Lower the sink 
carefully into the countertop 
so the bolts enter without 
interference.
Important
Not all Drop-In kitchen sinks require mounting hardware. If your 
kitchen sink does not come with mounting brackets, we recommend 
securing your sink with 100% silicone and expandable foam
(see bath sink drop-in instructions on page 4)
