Simple is good. Tar paper, plywood, caulk, and paint should do it. Never mind the cabinetry joints, just butt things up and screw it together w/ plenty of glue and caulk. Then roller paint it. I live in Florida, so there's no need for insulation. However, there's a need for a/c, which is why my darkroom is still the bathroom.
One trick I learned from having numerous contractors fleece me was to use good long screws instead of nails. Much sturdier, and you can put things together quickly w/ a power drill that has a screwdriver bit chucked up in it. Makes it a lot easier to take apart and set up someplace else if you move too.
