Ensure the vanity fits without blocking doors or walkways. Consider depth, width, and any plumbing needs, especially in compact bathrooms.
Materials
Bathrooms are humid, so choose solid wood, plywood, or water-resistant MDF. Avoid particle board, and look for countertops in water-resistant materials like quartz or granite.
Storage Needs
Choose storage options like drawers or cabinets based on your needs. Closed cabinets suit shared bathrooms, while open shelving works well in smaller spaces.
Compatibility
Choose a sink style (undermount, vessel, integrated) that fits your style and maintenance needs. Ensure faucet compatibility with the pre-drilled holes in your vanity.
