Tools: screwdriver, prybar.
Supplies: spackling compound (for patching damaged wall).
1. Remove any drawers and doors so they won't swing open as you carry the unit away.
2. Remove the countertop (including the basin, if it is a one-piece molded unit). Whether your countertop material is plastic laminate or tile, the surface material is applied to a plywood deck. You want to remove this entire deck, not just the finished surface. You can determine how the deck is attached to the vanity merely by looking up from underneath the countertop. Remove any screws. If the counter top is glued to the base, you may have to pry it off, and some older cabinets may need to be dismantled on the spot.
