OceanHomes- it's already been painted as seen in picture with Cornforth Re Silestone etc- I personally have a strong dislike to man made stones because they have no life. Marble and granite on the other hand have depth and beauty. I see your point re other colour. I have looked at white and grey granites but non of available ones have a striking pattern. And my floor are white. Ma

We would need pics. From your description it sounds a bit 'orangey' with the colours so maybe you need to lighten it - white or a dark charcoal/black contrast.

If you go for a quartz or other solid surface, then any fabricator should be able to do a table for you. You need to face the back with something, we used mdf when we did it, and attach legs of your choice. In laminate you would need to buy a breakfast bar type top and use edging strips on the ends, so would have width limitations.

Tricky one...is the original worktop wood ?....cant tell from pic. I'm guessing you would have to use a strong angled bracket that runs along the whole length and then a supporting pole. If you just want somewhere to sit for a short while could you sit where the bins are and put bins elsewhere (maybe in a cupboard?)
