We are in the process of building a new 40x60 shop. Should be ready to go in about 2-3 more months.
Our plans for a wash bay are only going to be:
Power America Hot Water Pressure Washer mounted inside the building with a reel on the outside of the building with 50-100 ft hose.
Also we got a stainless steel vacuum, car wash style, that we are going to mount on a concrete slab to vac the trucks out.
Its not the best set-up but will be better than what he had.
What is it that you guys have in mind for a wash bay????
