Bathroom Remodel Cost Ranges

Half bath cosmetic: $1,000-2,500. Full bath standard: $8,000-15,000 (most common project). Master bath full renovation: $25,000-50,000. Luxury master: $50,000-100,000+. Bathrooms have the highest cost per square foot of any room renovation because of the density of plumbing, electrical, tile, and fixtures in a small space.

Highest-ROI Bathroom Upgrades

The upgrades that add the most value relative to cost: updated vanity and mirror ($500-2,000), new toilet ($200-500), modern lighting ($100-400), fresh paint and grout ($100-200), and new faucets/hardware ($100-300). These cosmetic changes can make a bathroom feel new for under $3,000 total — recouping 80-100% at resale.

⚡ CalcWolf Insight

A bathroom addition (adding a bathroom where one did not exist) recoups 53-58% of its cost at resale — lower than remodeling an existing bathroom. However, going from a 1-bath to a 2-bath home increases the buyer pool dramatically, making the home sell faster even if the dollar ROI is modest.
