We have extended our kitchen and want to extend the original quarry tile floor, we can get some old 1 inch thick 6 X 6 tiles but what would be the best way of fixing them?, the original ones are laid on a bed of sand & cement so would it be best to use the same method, its not a big area, roughly 2.5M X 3M, about 320 tiles. I am going to put the concrete slab down but will get a tiler in to lay the tiles. Also what sort of cost might labour be, i am thinking about £200, we are in east midlands.
