We have four farmhouse style sinks in two different houses, and all present the same problem. It doesn't have anything to do with the material as two sinks are concrete, one stainless steel, and one composite stone. With the two kitchen sinks it's very frustrating spraying out the food particles from corner to corner. Food particles go from one side to the other, and it's very difficult to corral them to the drain. The two concrete bathroom sinks don't have enough slope, so when shaving and brushing teeth, the water and material flow to the opposite side of the sink. It's annoying to wash a 3' wide sink every time it's used. And gross if the sink isn't cleaned from side to side after every use. As a compromise, we're installing a farmhouse concrete bathroom sink with two drains and more slope. As I evaluate many things in life, a, farmhouse sink is a solutions looking for problem.

I've a friend with a Blanco sink that looks similar. The big issue is keeping it clean, because it's very hard to get the gunk out of those squared off corners. Personally, I'd go with something with rounded corners, even if they're only slightly rounded. We have an Oliveri Sonetto, which has modestly rounded corners (but is more expensive). http://www.harveynorman.com.au/kitchen-appliances/sinks-taps/oliveri-sonetto-undermount-sink.html That said, I don't think there's anything wrong with the quality of Blancos, it's the straight edge design that looks good in the magazines but is a pain to live with. You might have a look at Abey and some of the mid-range Clark sinks as well (our last house had a very serviceable Clark Monaco).

Quartz by any major manufacturer is basically made in the same way using the basically the same raw materials and process. Caesarstone just happens to be the "COKE" of the stone world and the advertising budget to match. Is it the "BEST" in our opinion there are better options, finishes and prices. Some of the better brands in Australia would be Technistone, Silestone and Samsung for finish, durability, price and after sales service. Though Smartstone have some very nice marble look ranges now as well that look and feel just as good as the top brands. Ikea, Bunnings where, if not still are using caesarstone brands of quartz. Though it does change around. like their fabricating companies

Could you swap the fridge with the wall oven, going by your photo both fridge and Wall Oven would fit side by side. I would definately have the fridge on the cook top wall and not on the other side of the kitchen. I see by the photo that the timber beam could be in the way, I would speak to your plumber who should have a simple solution on ducting the range hood. A simple one built into a special cabinet above the cooktop can recirculate or be ducted outside by either exposed stainless tube for your industrial/country look or have the ducting boxed in, the ducting can be flexable so no problem avoiding beams.
