Hi. Here's a pic of how it would look (similar anyway!). It depends if you want the sink to stand out or for the worktop to look seamless. As you're going for a shaker have you consider a butler or Belfast sink?

My initial reaction to the photos was that the kitchen units' colour somehow didn't quite 'gel' in the room and I was rather hoping colourhappy would come in and be able to cast her professional eye over it. I still really like the granite and I agree that at least changing the lower units will work. Perhaps the upper units need changing too? J Pleass, would you consider doing that?

There seems to be too much going on in your kitchen which is jarring, with colour and everything crowded around the old chimney breast. Perhaps the simplest thing to do might be to remove the backsplash and paint all the walls a warm neutral to tie in with the cupboard doors. I think the upper cupboards on the LHS of the old chimney breast could be removed to give a greater sense of space. As Jonathan has said, under cabinet lighting will brighten the space.

When we reserved the stone slabs at the stone yard we did indeed sign a disclaimer, it was our understanding that we couldn’t have the slabs if we didn’t sign. When I check their website, they don’t have the granite listed anymore, but then I’m pretty sure that we had the only 2 slabs they had of this granite, so this would make sense. Unfortunately we don’t have pictures of them. Thank you for your advice, I’m located just outside London so I will get in touch with Rossi Stoneworks. I just felt so clueless, so having a name of an expert to contact is a massive help. I did wonder if the marks were due to ‘sucker pads’ or something similar and raised this with the stone mason, but he said that wasn’t possible (I can’t remember the exact reason he gave), but I agree that the marks look so uniform in shape, which (I believe) points to something machinery related (as opposed to something naturally occurring within the stone). I fear that the disclaimer we signed may pose a problem - watch this space. I will add more on here with updates, in case anyone else experiences anything similar. Thanks again for your comments - I really appreciate it, I don’t feel as helpless now.
