This should be up to you. I have a 36" wide undermount with two bowls. The smaller bowl is 7" deep and the larger one is 9" deep. I love the big one for 'hiding' and soaking pots, but I feel it in my back if I try to scour a pot there. The granite adds an inch to the depths. I'm 5'6".

We just made this decision a few weeks. Initially we bought a Blanco sink that was 12" deep, but found that we could get something better and less expensive from a custom metal craftsman. We asked him to duplicate the dimesions of the sink we bought, and he thought 12" was way too deep. His exact words were " 7-8 inches are normal, 10 is considered deep." And that was the consensus of several folks on GW. We decided to go with 10", our friends have one this depth, and we really like it--they use a grid in the bottom, which raises things up a bit. If you've got 3cm granite, it will probably add a a bit over an inch to your depth. I'm not particularly tall, so I don't have to stoop over. We have lots of hand-washables and can always use the hiding space in the sink!

I have an Elkay undermount single bowl sink -- would never want anything more than 7" deep. The undermount will add a few inches and your back will hate you if the sink is any lower.

We've had our new two bowl undermount sink and granite countertop for about 6 months. The granite is 1 1/4" and both sink bowls are 8" so the total depth is 9 1/4". My wife likes the depth but wouldn't want the sink any deeper.

The taller you are, the more you'll have to bend over to touch the bottom of a sink and the less pleasant a really deep sink will be if you do any dishwashing by hand, I think. I'm 6' tall, my sink is 7" deep plus an inch and a half of countertop, and I wouldn't want it any deeper.

I really miss my 12 inch deep Blanco.
Water seems to end up all over the counter a lot more with the 8 inch sink in the new house.

It does depend on how tall the user is though.
Someone 6' tall would probably find it uncomfortable to use a 12 inch sink on a regular basis.

Hi,

Thanks for your comments. I went with a 7 1/2" Elkay sink and was concerned it wasn't deep enough. But if I add another inch for the granite, I think I will be fine. I thought with a deeper sink there would be less water splashing onto the counter. But I am pretty tall and a 10" sink felt way too deep for me. So hopefully the 7 1/2" sink will be o.k.

Thanks again for all your input!

One thing to keep in mind when going with a deep sink, especially if it is going to have a garbage disposal, is the height of the drain pipe coming out of the wall. Extra expense if you have to lower the drain pipe to be below the disposal outlet.

I have a 7.75" deep sink, and I love its depth.

I'm 5'2", and if I lay the broiler pan flat on the bottom of the sink to scrub it, I am right at the end of my effective reach. I'd have to stand on my tiptoes to scrub the pan, if my sink were any deeper.

A taller person could reach the bottom of a deep sink, but they'd have to bend over more than I do.

I don't get that much splashing on the counter, really. Some but I just squeegee it back into the sink (one of the great benefits of undermount or integral sinks, you'll find)

I get extra clearance from my faucet, which is shaped like an upside-down L--it goes up and out, but NOT back down, so I have something like 11" between it and the countertop.

Have you been to the "Kitchens" forum? Lots of people w/ lots of experience and insight. (I've decided what I wanted in my kitchen by realizing I did NOT want what someone else loved, bcs I valued different things)
