Kitchen:FireclaySinks
Fireclay sinks are distinct and ready for heavy duty use. Fireclay is 
coated in a high strength glaze which is resistant to scratches and stains. 
Fireclay is a very dense material which makes each sink hard to chip

install with a frame supporting the underside of the sink.
5.  Install a length of 2x4 vertically under each corner of the sink 
base to create support legs directly under the sink. 
6.  The sink should rest 1/8” 
inch below the top of your 
cabinets, ensuring plenty 
of clearance for countertop 
installation. Use a level to 
make sure the sink is even and 
will drain correctly. 
7.  Place the sink in the support 
structure. Apply a bead of 
silicone sealant between the rim of the sink and the countertop 
to create a watertight seal. Hook up the drain underneath 
according to the drain instructions and the sink will be ready 
for use. DO NOT overtighten your disposal drain, this could 
damage your kitchen sink. Use plumbers putty to make a water 
tight seal between the drain and the sink. 
8.  Cut the countertop with your template and install the 
countertop. Apply a bead of silicone sealant between the rim of 
the sink and the countertop to create a watertight seal. 
1.  Trace the rim of the sink on a piece of craft paper or cardboard. 
Measure the distance between the edge of the basin and

according to this measurement. Cut on the second line to make 
your cut out sheet. 
2.  Measure the front apron of the sink and cut the face of the 
cabinet to allow the sink to slide in. 
3.  Install the sink support in the cabinet base. See steps 4 - 6. 
4.  Install two lengths of 2x4’s front to back in the cabinet base. 
Build out the support structure and ledge for your Fireclay sink 
to rest on.
