I very much doubt there are any books on this, you could look for something from the Soviet era, but practices from those times might not be applicable today, quite a few tanks back then were made from titanium, just because it wasn't really a matter of expense back then, today it is welded or rotomolded plastic
PVC is on the fragile side, PE(HDPE) is a safer bet if the bath chemistry allows (I'm not familiar with copper plating), 6mm HDPE is about the norm used for tanks, ribbing is as needed, shape of the tank will dictate it (tall/narrow vs shallow/wide will require different reinforcement), double skinning is a norm as Adama said, cheapest way is particle board (15+mm thick) skinned with glass fiber vinyl resin (there are a lot of resins out there, need to make sure the particular one resists the chemicals in the tank), stainless steel is of course an option, local environmental safety regulations may restrict you in the choice of materials as well, so check with them first, then look for books and construction materials
and modern plating systems don't overflow over the edge of the tank on to the floor, and water isn't everywhere, there are drains like on roofs of houses from anything that can overflow to catch liquids before they have a chance to mix and cause even more problems than just a spill
