We have been remodeling our bathroom and needed a new sink and counter top. We really wanted a granite top but just didn't have the money to spend $300+ to get one. So this was our solution.
Step 1: Secure a table
Step 2: Prepping the granite
Next start cutting. Please note that I used hearing protectors, safety glasses and a mask.
I cut the stone with a 4 1/2" grinder equipped with a diamond blade. Go slow and let the saw do the work. If you try to hurry and press too hard you can damage the grinder.
If your sink comes with a template then use it to mark the hole cut out.
Ours didn't come with one but the sink was new and free so I can't complain.
