I just redid my bathroom for dirt cheap and am putting the leftover cash in to my garage/shed.
My garage is not huge, space is at a premium.
I have a shed right behind the garage with room to grow.
Going to extend the shed a little, put my air compressor and storage tanks back there, pull the central vacuum system out of the house because I never use it, and reinstall I nbn in the shed.
Going to wire them to switches in the garage, run the hoses to a couple points inside, and have a pressure dial for the compressor mounted to the connection points.
I also have a spare furnace fan I use to create positive or negative pressure set up by a window, and I am going to move that in the the shed and run the ventilation from there as well.
Going to save a ton of room this way. Getting the shop vac, compressor, fans, storage tanks and all the shit that goes with it out of my way will free up the entire back wall of the garage, not to mention the extra storage space along the new wal space of the shed.
