When sourcing bathroom vanities, the choice of base material is critical for durability. Solid wood (such as Oak or Rubberwood) offers premium aesthetics and strength but must be properly sealed. For high-humidity areas, Plywood with a melamine or veneer finish is often superior to MDF or particle board because it resists swelling and warping. For the countertop, Sintered Stone or Quartz is highly recommended due to their non-porous nature, scratch resistance, and ease of maintenance compared to natural marble.
