Bathroom Remodel Cost Calculator

A bathroom remodel packs a lot of trades into a small footprint, which is why the cost depends so heavily on the finishes you choose, the labor those finishes require, and how complex the layout changes are. The 2025 Cost vs. Value report put a midrange remodel of an existing 5 × 7 ft bathroom at $26,138 on national average. Having a clear read on those drivers before work begins is the difference between a renovation that stays on track and one that spirals past its budget.

The calculator works from a fixed table. You pick the bathroom (half, full or master) and the scope (cosmetic, mid-range or upscale), and it returns that combination's low and high estimate, from $3,000-$5,000 for a cosmetic half bath to $45,000-$60,000 for an upscale master bath, along with a typical timeline. The breakdown splits the midpoint of the range into fixtures (20%), tile and flooring (20%), plumbing (15%), vanity and countertop (15%) and labor (30%). Nothing is adjusted for your region, and layout changes such as moving plumbing are not priced separately.

Set aside a 15-20% contingency before you start, because mold remediation and hidden structural repairs have a way of surfacing only after the walls are open. Permit fees are another line item people routinely overlook, and the calculator does not include them; they depend on your municipality and the scope of work. And when you are weighing finishes, lasting function tends to outlast whatever happens to be trending this year.
