I would dedicate one corner of the shop to a mechanical space for your air compressor, dust collector, electrical box, basically the big tools that make a lot of noise. But I would also put a toilet, shower, and sink in it, but scavenge a design from about a 40’ boat. These small yacht bathrooms are designed so the whole room is a shower, so everything can get wet. Figure about 4 square foot of space. Mostly it will just be a toilet, but sometimes being able to wash off the dust before coming inside can be a huge advantage.

As long as you are in the construction phase I would also run 200amp electric, water and plumbing, and a large natural gas line. As well as two additional underground conduits because… well because its cheap once the trenches are already open, but a royal pain to do later.
