These are nothing more than pretty plastic buckets with a liquid solid separator ($55 on Ebay), and a stirring stick, seat, vent fan and lid. It wouldn't take much to build one out of wood but the problem with wood is it absorbs liquids so one would want to do it with plastic. I have some solid surface counter top material that would work but that stuff is heavy. Maybe make it out of wood and use a shower pan PVC liner to keep the wood dry. PVC liner is $40 bucks at big box store. I have the wood. $55 for that separator is a bit much for an injected or vacuum formed piece of plastic.
Fiberglass is the answer - either wood covered with glass cloth and polyester or epoxy resin or a total fibeglass layup. Same way one would build a custom icebox or your boat.....keeps the liquid out very well.
