Or… you could always go with end grain block flooring!

Your power tools would then sit on sound-dampening material, your hand tools would land on an edge-friendly surface if you were to drop them, and your feet and knees would thank you for not making them walk on solid concrete all day long!

As long as you’re building a shop from the ground up, you might as well not skimp on the flooring!
