To be fair, most of the worktop discussions were in the other thread ("Critique my Kitchen Design")
But it's called Silestone Eternal Charcoal Soapstone

If you've had any quotes for the non "Eternal" ranges, then prepare to fall off your chair. What you see there was £3300 and i tried about 15 places, battling them against each other to get the best price!
Oh and it's in the "Suede" finish. The standard finish is polished but this gives it more of a matte look/feel.
Pictures really don't do it justice though. It's incredible.
The benefit with the "Eternal" range, is that they do it in a jumbo slab which is 3.2m which means less joins. I think the standard range only comes in at 2.7m lengths so we wouldn't have been able to have the sink/induction length as one piece.
