REPLACING YOUR OLD SINK:

 

Note: If replacing a sink in an existing counter top, the sink cutout in the counter top 

must not exceed 327/16” or be more than 207/16” from the front edge. If the existing cutout 

exceeds these dimensions then a new counter top is required. Measurements are based 

on 24” deep base cabinet and 25” counter top.

IMPORTANT - Refer to the counter top manufacturer to determine the appropriate 

cutting method for your counter top.
IMPORTANT - The clip system on this sink is designed to hold it in place while the 

silicone dries. If the sink opening is too large the sink can be weighed down to hold it in place while the silicone 

dries. Take care not to scratch the sink if using a weight.

INSTALLATION INSTRUCTIONS

Verify that your counter top is level.  Measure the false 

drawer openings on the kitchen cabinet to ensure the sink 

apron will cover the entire opening. 

Note: If false drawer fronts are larger than the width and/

or height of the apron,  fill in any gaps. 

Remove false drawer fronts from the cabinet where the 

apron will be located.
