A 36-inch vanity can include drawers and cabinets, but the most amount of storage can be found in vanities between 42-60 inches wide if your bathroom can support it.

And if you're designing an Americans With Disabilities Act (ADA) compliant bathroom, the sink countertop of the vanity unit should be 34 inches above the floor to allow wheelchair access.

The optimal vanity height for men typically falls between 34-36 inches, while women often prefer 32-34 inches. If you’re sharing the space, 34 inches hits the compromise jackpot.
