I'm building an outdoor kitchen and have to buy the countertops, or at least hire a countertop guy, soon.
Because (a) there is a gas grill so I can't use flammable materials like plywood and (b) it's outside so ply or OSB or MDF (?!) would rot or turn to mush, what, if anything should I use?
The maximum span is 26" between supports. This is over an alcove for a fridge. That area will be supported on three sides but open at the front. If push comes to shove I think I might be able to squeeze in some 2" deep angle iron but I would prefer not to.
Don't mind paying for 1- inch thick slab but obviously I don't want to spend hundreds on a countertop only for it to give way.
One idea I had was cement backer board.
