Bathroom vanity installation costs range from $200 to $1,000. Prefab vanities fall on the lower end, and custom vanities fall on the higher end. You may also need plumbing connections for the sink and faucets. Plumbers charge between $45 and $200 per hour, so account for that in your budget.

Stainless steel vanities are exceptionally durable and resistant to corrosion, making them an ideal choice for contemporary bathrooms. They are easy to clean and maintain and are impervious to moisture. MDF is an engineered wood product that is often used for cabinet and vanity construction.

Typically a custom vanity costs about twice as much as a prefab vanity because there are more subcontractors involved in making and putting the vanity together. Plus, you need to purchase materials separately from various vendors (vanity base, counter top, sink, & hardware).
