Keep an eye out for those big holiday sales. You know the usual suspects: Memorial Day, Fourth of July, Labor Day, and of course, Black Friday Sales. These are often the best times to snag a great deal on bathroom vanities due to the major sales and discounts you'll find.

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.

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).

With the most common design being a top-mount or under-mount sink, that means most vanities will be measured to the surface of the countertop. Standard bathroom vanity height starts at 32” and goes up to 36”, with 34” typically leaning towards the new universal average.
