Installation & Assembly
Options include installation at 
various heights, various undermount 
reveals, and various amounts of 
forward overhang of the apron front. 
The choices made will determine 
what type of additional support will 
be necessary in the base cabinet. 
Presented here are just some of 
options and more popular mounting 
techniques.
THE STEPS
•  Evaluate the style of apron sink being 
installed and determine the type of 
mounting to be done. 
•  Keep in mind that unlike other sink 
styles which are dropped into a hole in 
the countertop, and supported by the 
countertop; apron sinks are positioned 
through an opening in the front of the 
cabinet and supported, only by the cabinet. 
•  Measure the sink and cabinet in order to 
properly prepare the base cabinet. 
•  Install necessary support braces. Several 
types of supports can be customized to 
uphold various types of sinks in various 
fashions. One typical technique, using 2˝ 
x 4˝ supports, with or without a plywood 
platform, is shown here. 
•  Place sink in position on the base cabinet 
supports. 
•  Clean the surfaces of the sink and 
countertop which will meet, with denatured 
alcohol. 
•  If undermounting the sink, apply a bead of 
silicone along the outer edge of the sink 
rim in order to form a secure bond with the 
countertop. 
•  Attach the countertop making sure of tight 
contact with the sink. 
•  Re-check that the sink is properly aligned 
and level. 
•  Remove any excess sealant along edges.
