 installing kitchen sink
Author: ekm92 (GA)

I'm replacing a drop-in twin-bowl stainless steel sink with a Kohler single-bowl. The rear, left and right sides of the new sink set flush with the counter when dropped in. The middle of the front rim sets about 1/16" higher than the left and right sides. If I put my full body weight on the front lip it will touch the counter top but I can see the front wall of the sink flex a bit. I have not installed the mounting clips yet. I'm afraid that the pressure needed from the clips on the front will cause a bend in the lip, cause the front wall of the sink to warp or cause the counter top to crack from the pressure being put on it. I returned one sink thinking it was a design flaw but the second one does the same thing. Should all sides of the sink set flush with the counter top before the clips are installed? When the sink is in the box I can put a yard stick across the front lip and see the middle is higher than the left and right sides. The counter top is perfectly flat. Is this something to worry about? I don't want to damage the sink trying to flatten it out if it's not correct to begin with.

Thanks

i've dealt with worse.. just strategically locate a couple of clips near the high spot and tighten away. use a good polyseamseal caulking all around the opening before setting the sink and wipe away any excess immediately after tightening.

In almost all cases there will be a portion of the sink that doesn't sit perfectly on the countertop . Sometimes I'll place a weight on the high spot til after the caulking has dried.

Thanks guys! I was afraid of bending the sink or hurting the counter top. Used the clips from the old sink in addition to the clips that came with the new one. Have probably nine clips across the front lip of the sink. Everything sits flush now.

Thanks for the advice.

sounds like you could park an F-450 on the side of the sink and the front won't lift.. good job..

The F-450 wouldn't be able to pull the sink out of the countertop, that's for sure.
