A basic update, meaning new fixtures, vanity, flooring, and paint with the existing layout, generally runs $8,800 to $20,000. A mid-range full remodel with a tiled shower, new tile floor, vanity, and fixtures runs $20,000 to $40,000. A high-end or gut renovation, or one that moves plumbing, runs $40,000 to $55,000 or more. The Massachusetts statewide average sits around $17,600, though that number includes a lot of smaller updates. Moving the toilet, tub, or shower is what pushes a project toward the high end, because it means opening the floor and reworking drain lines.
