After some more research and a good bit of speculation ive decided on regular aquarium grade silicon and 1/4 in red oak plywood. Is there a specific type of polyurethane or is any Polyshades ok, and what would i seal (not sure if thats the correct term i meent to coat entirely after coating with the polyurethane) it with? also flooring, can i use any vynil tile or can i get a list of options that you all have used? Thanks again - Sravis
