A built-in sink is one that sits on the worktop. These usually have built-in drainers, as pictured below.
You need:
-
mounting clips
-
sealing tape
-
jigsaw
-
screwdriver
-
pencil
And this is how you do it:
-
Place the sink upside down on the worktop in the desired location.
-
Trace the outlines with a pencil.
-
Draw another line about 10mm inside the outline. Now cut a hole in the countertop along this inner line.
-
Stick the sealing tape along the bottom of the sink. Be careful not to crease.
-
Now attach the clips to the sink in a horizontal position.
-
These anchor clips are for worktops with a thickness of 30-40mm. If your worktop is thinner, you can clamp wooden wedges in between to secure it.
-
After placing a mounting clip on each corner of the sink (or on 4 opposite sides in the case of a round sink), place the rest evenly around the sink.
-
Now use the screwdriver to tighten the screws of the clips to anchor the sink in place.
- Note: If the overflow touches the countertop, you can simply swap out the thick gasket for silicone (this can happen if you have a thicker countertop).
