The trade-offs become clear on delivery day. These units arrive as heavy, unified pieces. A 72-inch freestanding vanity with a pre-glued quartz countertop easily tips the scales at 280 to 340 pounds.

Standard delivery covers liftgate service to the edge of your driveway. Drivers will not maneuver a 300-pound wood and stone unit up front porch stairs, around tight hallways, or into a second-story master bath. Bringing the unit inside requires at least two capable people, heavy-duty moving straps, and a clear pathway.

Plumbing alignment is another practical challenge. Custom vanities leave open cavity space for varied pipe locations. A factory-built, pre-assembled vanity cabinet uses dedicated drawer boxes and structured internal dividers. If your rough-in waste pipe and hot/cold valves are offset from standard center lines, you will need to cut the rear paneling or hire a plumber to relocate the wall stubs. Budget an extra $200 to $400 for pipe modifications if you are retrofitting an older home.
