Hi Wayne, Porcelain slabs are good for worktops without the cost of granite or dekton. The pros: Cheaper to buy Easy to install (laid on cement base) Perfect for outdoor use Hard wearing Good choice of colours Cons: There will be a join where every tile meets Cut edges don't look great. We try to design the kitchen so that all edges on show are machined. Installation wise, they sit on top like a normal worktop, they don't need to sit on ply or a base. They are very strong and will support the weight of a kamado. That sais, we normally put a central support under our worktops if there's a kamado going on top. many thanks jody
