MDF or Medium-Density Fiberboard is an engineered wood made from composite wood pieces and fibers, which are held together with either a wax or resin adhesive. A thin decorative veneer layer is then stretched around the composite plank of wood. MDF is denser than plywood, and is used all over the furnishing industry. It is NOT to be confused with plywood.

MDF is one of the most economical materials in cabinet construction, and that’s its true benefit. In the past, its durability came into question especially when placed in humid bathroom conditions. But when finished properly, MDF can be used in the bathroom with few if any problems. That’s the rub, though: MDF is a comparatively inconsistent material, due to variance in the fiber sizes and qualities of the many different woods used to make the material, and so it’s hard to determine how “well finished” an individual board may be.

MDF is commonly found in cheaper vanity cabinets, and although it is usually fine, it’s not the best choice for your bathroom. It’s best to keep your MDF cabinets in the kitchen and other drier environments.

MDF cabinets don’t expand and contract as much as real wood, but they can be damaged by moisture if water is allowed to penetrate the surface of MDF. This would result in some serious swelling in your vanity. With proper ventilation and perfect sealing of the material, MDF can be used in the bathroom without any problem. As an added precaution, you can seal the backs and edges around MDF cabinets with oil-based sealer and a few coats of poly sealer. This should prevent warping and shrinking, and is a recommended step to take if you buy an MDF vanity.
