hd4mark, not sure what part you're referring to when you say top, but the top of the freezer part is just stick on floor tiles. Figured they'e be durable, would hold up to moisture, etc. The signboard is just pine painted with chalkboard paint. Had to buy a quart of the stuff, but my daughter can use it for projects for the grandkids. I did see something online after the fact about making your own chalkboard paint.
