I'm looking to replace the sink in my quartz countertop. The new sink I've purchased is a drop in sink of the same dimensions. It "fits" into the hole, with the exception that on both the left and right side of the sink are a couple tabs. So the sink fits into the hole, except for the tabs. These tabs sit under the lip, but would require notching out the counter in 4 spots by about 1/8". The sink would almost fit in like a puzzle piece.
I want to understand the risk of getting a grinder and doing this myself. Is there a chance of really messing up my counter top? Is this a DIY job, or call a Pro due to the complexity and mess?
Tabs under the sink: The instructions/cutout is a rectangle with 4 sides. It doesn't move out/in to follow around the tabs. The hole to cut would take into account the size of these tabs. Thus, if installing new, the whole would just be bigger than the one I have now. Instead of making the entire hole bigger, I'm hoping to cheat and notch the counter top for these tabs under the lip. These tabs are for clamping the sink.
I cannot find the install instructions online (it's just the 1 large page cutout diagram), but this is the sink: https://www.blanco.com/ca-en/sinks/vision-f/vision-210-silgranit--pdp-59.046/
I've added a picture of the tabs. They are not removable Looking at the picture and thinking a bit more about this --- if I were to only notch out for these tabs, that means the sink would most likely be resting on the counter top on the dark/black material. The grey lip would not sit down flush, and thus there would be a gap. So my original question is slightly different, I originally thought about grinding out a 4 small parts for the tabs, now it seems I really do need to widen the hole. Is this a job for a Pro?
