I have purchased an antique dining server which I would like to use as a bathroom vanity. And I would actually like to tile the top. The existing top is not appropriate for tiling because in has an elaborate edge and because it would be too thick. So I would like to replace it and also build a little frame around the new top to house the tiles. What's an appropriate material to support that construction? Can I go with compressed particle board (it will be concealed) or should I go for solid wood. Please keep in mind that I don't have a planer or a router. All I have is a table saw, a miter saw and a router.
Many thanks in advance!
