I have two piles of reclaimed and unused granite in my backyard. One pile is formed into the shape of an outdoor kitchen, and the other pile is stacked to minimize the ground area it takes up. I am now selecting between two 4x8’ slabs to use on a table top.
I also have several items from the local Habitat for Humanity outlet where they have a lot of materials reclaimed from high end remodels. I bought a couple of stainless steel sinks from them, one was never used. Most of what I’ve bought there are old tools, abandoned by homeowners, handymen, and contractors. They have plenty of kitchen counters and cabinets and lots of doors.
