Hi all. I am wanting to make my own hearth - purely decorative, not for a burner. Has anyone made one before? I was thinking laying some tiles over paving slabs. The height of the concrete floor to the lip of the recess is 70mm so would probably have to stack 2/3 slabs on top of one another (stretcher bond). Ideally, I would have lowered the base of the recess but it would mean having to get it all re-skimmed at the bottom.
