I’d really like this Ikea double domsjo sink on my island www.ikea.com/gb/en/catalog/products/S79931650/ but I’m planning quite a slimline island so, 210cm wide and 70cm deep. The domsjo is 66cm deep so only got a tiny bit of worktop behind it. Am I going to end up with a ridiculous situation whereby water splashes off the back of the island? Has anyone done similar with a big sink like this? Do I need some more worktop space behind the sink, or even a little raised bit of worktop, like a mini splashback, or would that just look crap. Would love assistance, or any feedback on the domsjo sink. I’m such an amateur at all this 
Thank you
