Garage Workbench Dimensions

My workbench is built higher than most at 42 inches from floor. Doesn't mean I'm tall. LOL
A concrete floor will reak havok on the legs and feet so I have a wooden platform to stand on. It will lift up and serve as a blind to power tools stored under the bench. Dirll shaving and the like drop through it and stay there until I lift it to sweep.
Keep in mind that a sturdy workbench is just that. If you have plenty of wall space you might wait until you catch someone remodeling indoors and grab used kirchen cabinets. Doors and drwers are nice too. A section of formica countertop is handy as well
