I think you're going to really appreciate the new sink. Mine is that size and I think the 10" depth is perfect. Not too deep and the 2 inches does make a difference. Mine curves a little in the back and there is room only for two holes. One in each back corner. It's in my laundry room, so a single pull-out faucet and soap dispenser is all that I need.
If you aren't sure about the holes; if you aren't sure about the color then I think you should wait. Personally, I like black and tan combinations. But I don't have a clear picture in my mind of the biscuit color.

I took a look at your sink. It's like mine and you will not have room for 3 holes. I think that is your only issue. Any color is going to be a contrast to your black counter top so it's a matter of your color preference. I've seen the black ones in black counter tops and it looked great too.

Am I missing something?

How do you get a 25" sink into a 24" base cabinet?

The sink only needs about 19 inches of hole space and it's 22 inches front to back. 25" wide. (I'm assuming the base is wider than 24 inches).

Hi Dian57,
Is this the sink that you have? See link at bottom.

I'm not sure if it is yours or not, if it is yours then you should be able to drill all the holes that you want. That is because on the model I linked to, the holes would be in the countertop and not actually in the sink.

If you have a different sink model that has the platform built on to the sink for the faucets, then you could still drill new holes but get ready, that composite material is harder than cryptonite. I went through 2 brand spanking new hole saws drilling one hole in one of those sinks.

I haven't needed to do that again but if I do I will purchase a diamond coated hole saw like you use on granite.

Yes, Banjo, that is the sink on order. And yes, the sink base is only 24"--I didn't even realize THAT issue.

Think I'll call tomorrow and cancel. I need more time to consider this.

Thanks for the opinions.

Yes you need to reconsider. Measure and re-measure before you commit. Good luck.

Blanco allows you to drill holes through their composite sinks only where there are knockouts. If you drill them where there are no knockouts, their warranty will be void. Sometimes drilling them "where you want them", will mean going through some molded support stuff that will make it VERY difficult to install your fixtures. Just something to think about...

I'd also say that's a very high price for a Blanco Silgranit, though it is what Expo sells them for. I got mine for half price by searching online. Also, if you want a contrast but not too much of one, think about the gray / silver sink. That's what we have.

Have you considered the black sink? Unless you want your sink to be a focal point, using the black will allow your eye to travel around the room and not "stop" at the contrasting sink. I have black and love love love its low maintenance. Yes, the silgranit is $$ but it's worth every penny!
