There's no one-size-fits-all answer to this question, as the cost of raising a vanity can vary depending on a number of factors. For example, the type of vanity you choose (freestanding, wall-mounted, etc.) and the materials it's made from will affect the price. Other considerations include the size of your vanity and the complexity of the design.
Generally speaking, you can expect to pay anywhere from $200 to $2,000 for a quality vanity. Of course, you can find cheaper options, but they likely won't be as durable or stylish as a more expensive model.
When choosing a vanity, be sure to keep your budget in mind. But also keep in mind that a vanity is a long-term investment, so it's worth spending a little extra to get a piece that you'll love for years to come.
