If you don’t need a sink in your vanity, then you also don’t need one with the structural integrity to hold up a sink. PVC piping is inexpensive and easy to use for building. Purchase the pipes, end joints and a pipe cutter from the hardware store and build a custom sized vanity. For the countertop, cut pipe pieces to form a top surface and add a piece of transparent thermoplastic for a smooth surface.
If you don’t want to spend a dime on wood, head to the back of your local grocery store at closing time and ask a representative. You will be able to find an ample supply of milk crates that can be stacked, screwed and painted to form the perfect vanity. If milk crates sound too tacky, cover the exterior in wood veneer or faux leather to perfectly hide your skeleton.
If you like bringing the beauty of nature into your home, consider designing a vanity that comes complete with plants on both sides. Find some planters that are 2 feet high and a piece of plywood that is your desired vanity length. Measure and cut square holes into the top of the plywood just slightly smaller than the planter underneath. Glue the pots to the plywood for stability and either paint and seal it or cover the top in veneer.
Search your local thrift stores for an old six-drawer dresser with mirror. Remove three of the drawers along with the drawer casing and front frame. Smooth out the edges and cover with veneer or re-stain if the dresser is solid wood. Use the remaining drawers for storage space and set your chair under the open space.
