Just had a new 3cm thick granite countertop installed, and I have a new SS drop in kitchen sink.





On the underside, I applied a thick bead of silicone around the perimeter, plus the clips provided by the sink manufacturer.

However, I was able to apply the clips only on the left, right and back sides.





The front side the sink is position so close to the front of the cabinet the granite cut out is basically flush with the cabinet frame, so all I have along the front edge is a bead of silicone. Is this enough?



or is there other ways to secure the front edge of the sink to the granite?

On a related subject, I am about to install a kitchen faucet on this sink tomorrow. Single hole Kohler Tyne pull down faucet, it can be installed directly on the SS sink hole as is, or it comes with an optional deck plate. I have been debating whether to use the deck plate. Do you think as a rental the with deck plate is more "tenant proof" or the sink itself is plenty strong?

The front edge should be just fine without the clips. Undermount sink would have been a different story.

There could be some flexing going on with a single hole mount. The single hole mount definitely looks better. What I would do is fabricate a stiffener plate that can go under the sink. I would use a 10in long x 2in wide x 1/4in thick aluminium plate with a 1 3/8 in hole in the middle. You can use plywood if you cannot source the aluminium.

Hi George,

What if he just used the top plate that comes with faucet and installed it on the bottom side to act as a stiffener ?

Just a thought.....

The manufacturer provided 12 clips for drop in mounting, I was planning on 3 clips each side. I put 3 on the left, 3 on the right, but due to the faucet hole in the back, I only installed two on the back side leaving the middle so it won't interfere with the faucet installation, and none in the front. So now I have 4 clips left. I wonder if I should put one more on the sides and two more on the back just to use it up or not necessary?

Stiffener on the underside? OK I just thought the same as Curly I could use the same deck plate on the underside?

Curly, I had the same exact thought when I read George's idea on a stiffener plate on the underside. I am going to give it a shot and see if it fits under there.

Sure, the deck plate can be used. A pull down faucet, with its large overhang, will flex the sink ledge a bit. The only reason I suggested custom fabricating the stiffener out of aluminium plate is that the larger the stiffener, the less the flex. The aluminium can be made large and still fit the available space.

OK, I installed the faucet today and attempted to use the provided deck plate on the underside as a stiffening plate. That didn't fly.

The reason is, I don't think that deck plate even if used above would stiffen anything. It is a very thin (and contoured) metal shell with a plastic filler inside. I could very easily bend it with my hands, I think all it does is to cover two extra holes if you had a 3-hole-faucet previously and it doesn't help with the faucet's rigidity (it may but just a tiny bit). I tried it on the underside and concluded it wouldn't work too well, a piece of 1/2" plywood would do much better.

You did not provide one piece of information - does the sink flex?

George, on normal usage like swinging the faucet left or right, pulling down the head and retracting, no flex at all. But if I grab the faucet high arc and pull it towards myself like I would a crow bar, yes I can see some flex. This is not normal usages obviously, but one never knows about what tenants may do.
