No, but pretty easy to imagine. White fiberglass panels on walls so that it is easy to wash. (Restaurant grade FRP panels) Lights around top of the walls so there are no shadows, 8" platform on the floor to raise client up for better access to legs. And an exhaust fan over the platform with a filter over it to catch overspray.
I also put a drain in the platform and a pump under it to pump excess water to the drain in the back, but this isn't really necessary. I don't think I would worry with the pump if I were doing it again.
