800x400 Black/Grey Sandstone Slab for Patio - Suppliers?

[st96001414]

As per the title, we're in the process of levelling the back and will soon be ready for slabs. We love the 800x400 slate tile look (like photo attached) but appreciate after discussion with the chap who is laying the patio, the slate tiles of approx 10-12mm are a little on the thin side for a house we can see ourselves staying here for years to come.

So, we're looking for a solid Indian Sandstone equivalent 800x400. I've been searching this weekend and most places will sell me only 800x400 as part of a pack of smaller tiles to make up a mixed set. The only place I have found that sells something similar is this place online (Rock Unique):

Could anyone else advise if you know of other suppliers that sell what we are looking for?

Appreciate any advice guys...

Speak to steve at london stone. If he can;t do it he can certainly point you in the right direction.

You could more easily and cheaply get black limestone. It fades very quickly and will be mid grey within a year.
