PVC for shoestring budget equipment?

I ran across this today. Seems like the dish washing station and handwashing station could be of use for a family. Maybe a smaller version of the prep table, that could be a cook table too for a small camp stove. Thoughts?

Neat. I could see this more towards cabin use. Strange they do not offer a shower stand of some sort.
