A Guide to Granite Counter top Sink Installations
A sink Installation can often be the crowning jewel in your kitchen’s glory, so it is important to get it right. In this latest blog, we will look at four different types of granite countertop sink installations and the tools you need in order to achieve the look.
The Undermount Sink
The undermount sink is the most popular granite countertop sink installation as it really does get the best out of the stone. The undermount allows you to show off your beautiful edging work, achieved with our polishing pads for stone and your attention to detail in the drainage grooves. Undermount sinks cannot be achieved with the cheaper worktops such as laminate or Formica, so it really does provide the customer with the opportunity to show off their fabulous stone worktops.
These tops are popular as they are easier to than other granite countertop sink installations as you can wipe the water and debris directly into the sink, without trapping it in the lip of the sink as you would in an overmount sink.
The Tooling - CNC
Fabricators can achieve this look by cutting out a hole with a core drill and then using a router to route out the sink shape. To achieve the true professional look you can follow with a 20mm polishing wheel. Fluting wheels will add your drainage grooves and should be followed by an abrasive polishing wheel to polish it to a high shine finish.
For a different shape to your drainer grooves use the flue tips from position 1-4 to achieve a honed finish and hand finish with Electrofacing sheets.
The Tooling – Hand Tools
You can achieve this look by cutting the shape with a core drill and then using a Vacuum Brazed Drum to smooth the edges. If you are cutting a simple straight sink you can simple core the corners and cut out with a small blade. Wet polish out the edges with a diamond finger drum or for dry polishing use our dry polishing drums.
Another method for the more skilled fabricator would be to use a curved granite blade to cut out the sink hole.
Inset / Overmount / Drop In Sinks
Whatever you call them, these installations involve the sink unit sitting on top of the granite countertop. These installations usually come with the drainage board attached to the sink, so do not require fluting tools to create the drainage grooves in the stone. This traditional style sink will simply drop into the cut out hole and is then usually sealed with silicone.
Although these can be tougher to clean than the undermount or the Belfast sinks they are usually very easy to replace should you need them to change. Simply unseal, take the sink out and drop the new sink in, without any risk damage to the stone.
This is a relatively easy install as opposed to the undermount style sink. You will still need to cut out the sink shape with a core drill and a router but as the edge is hidden you will not need to do any polishing. Simply drop the sink in and seal with the silicone.
The Belfast / Butler Sink
This style of granite countertop sink installations is quickly gaining popularity in kitchens, particularly in the county kitchen décor. The sink rests its weight on the kitchen unit, with the exposed front edge. Just like the under mount style, the Belfast is installed under the granite countertop, exposing the edges and allowing you to show off your fluting skills on the drainage grooves. You will often find the Belfast used as a colour contrast to the countertop or kitchen units. The back section of the granite tends to be quite weak as it is bridging the two sides together, so some fabricators will opt to have this as a separate piece.
The tooling required for this look is exactly the same as the undermount installation.
The Tooling - CNC
Fabricators can achieve this look by cutting out a hole with a core drill and then using a router to route out the sink shape. To achieve the true professional look you can follow with a 20mm polishing wheel. Fluting wheels will add your drainage grooves and should be followed by an abrasive polishing wheel to polish it. For a different shape to your drainer grooves use the flue tips from position 1-4 to achieve a honed finish. The sink does not need a fixing clip to hold into place as it rests on the kitchen cabinet. Silicone will still be required to provide the all-important watertight seal.
The Tooling – Hand Tools
You can achieve this look by starting with a core drill in the two top corners and using a small blade to cut between. Wet polish out the edges with a diamond finger drum or for dry polishing use our dry polishing drums. Use silicone provide the all-important watertight seal.
The Roll Top Sink
The roll top sink is not a common installation and can often be seen as a very superficial look. It does, however, have its benefits. The roll top sink is easy to install and will avoid any water puddles on the stone.
We said this was an easy installation and we certainly weren’t exaggerating. As the roll top runs all the way from the front to the back and is fully supported on the kitchen unit you do not need to cut out the sink shape or etch in the drainage grooves. Simply seal with silicone to the countertop and you are good to go!
