The standard depth for finish countertops is 24 inches
Upper counter cabinets are built with an average depth of 12 inches.
Upper cabinets above the refrigerator and other large appliances are often 24 inches deep (twice the average depth) to make accessing them beyond the appliance possible.

STANDARD HEIGHT AND DEPTH OF BATHROOM VANITY
Standard height of a bathroom vanity is 30- to 32-inches.
The standard vanity depth is 21 inches
In a small powder room, you can gain floor space by trimming at least part of the vanity to 18, 15, or even 12 inches deep
For a double sink, you'll need at least 60 inches from side to side, 72 inches if possible.
You might also find the 30- or 32-inch standard height of a vanity too low. If so, consider building up the toekick on a stock vanity or ordering a taller one that stands 34 to 36 inches off the floor
