You only need to cut a hole for the drain - we didn't use any silicone or anything to seal it to the countertop but you could if you wanted. I just didn't like the way it looked. The flat bottom just means you do have to clean it more often, since toothpaste and soap don't wash down as quickly, they stick to the porcelain and dry there making the sink look scummy. I will offer one other word of warning - make sure your vessel sink has an overflow drain. Ours did not and while its not a problem in our house, if we had kids we would have had a flood seven times over. [EDIT: I googled that sink and it looks like it does have an overflow. Also, now that I think of it caulking the bottom would probably be a good idea w kids so water doesn't get under there and get nasty.] This post was edited by Swentastic on Thu, Jul 24, 14 at 14:39

I have a similar color scheme in my kitchen. Basalt slate formica countertops (dark gray/black), alder cabinets, oak floor. I chose to do the Silgranit Super Single in anthracite, and I love it. IMO, anthracite looks great with dark countertops. I'm guessing with quartz you would undermount the sink? With the anthracite it would pretty much just disappear into your countertop. Stainless would look nice too, but since you are asking about silgranit my vote is for anthracite! HTH.

Thanks teechah. I have mannered gold in the guest bath with black/red accents. The office is ryegrass with black furniture and the guest bedroom is a tan (can't remember the name), with a black iron bed with a tan, black and red striped comforter. I was leaning toward a chocolate accent wall.....because of the sheen of this comforter, I think I need colors with a "dusky" feel. Not necessarily darker colors, just a dusky tone, if that makes sense. The blue I have on my walls now is a very clean light blue and in my opinion it doesn't flow well. A different shade of blue might work well, though.

Many who have vessel sinks in any bathroom but a powder room tend to get them replaced with more traditional sinks. Some are large enough, but vessel sinks have the difficulty of not easily being able to wipe water from the counter back into the sink, and smaller ones are difficult to do such simple tasks as shave or brush teeth - so the thought of washing dishes in one seems absurd. Even the bathroom type of vessel sink seems to be waning. If you found one large enough to wash dishes, you have the difficulty of the raised sides which are not convenient for doing dishes, wiping counters or prepping a meal. Kitchen surfaces have to be practical otherwise they will not sell well. Most would not find a type of vessel sink in the kitchen practical. Many other types of kitchen sinks function very well, so consumers will pick the functional sink over one that does not function well. Today, the under mount sink is very popular because it functions better than the older over mounts. The under mount sink allows water / crumbs on the counter to be wiped right into the sink and does away with a potentially gunky, moldy caulk line. I imagine people will want more this type of set up then one which increases the sides of the sink above the counter.
